Tropical Storm Arthur Discussion Number 10
NWS National Hurricane Center Miami FL AL012020
1100 PM EDT Mon May 18 2020

Arthur's cloud shield has shifted to the left or north side of the
cyclone's direction of motion since the previous advisory, which is
a distinctive sign of a tropical cyclone beginning to lose its
tropical characteristics, especially now due to the cyclone moving
over 23 deg C sea-surface temperatures. However, there remains
enough convection within 45-75 nmi of the center for Arthur to still
be classified as a tropical cyclone. The initial intensity has been
increased to 50 kt based on a recent 0129 UTC ASCAT-B overpass that
indicated several 50-51 kt wind vectors existed in the northwestern
quadrant.

The initial motion estimate is 070/13 kt. Arthur should move east-
northeastward tonight and then turn toward the east by Tuesday
morning as the cyclone moves around the northern periphery of a
low- to mid-level ridge. On day 2, all of the global models are
forecasting the mid- and upper-level circulations to separate
from the low-level circulation, with the latter feature dropping
southeastward and then southward around the eastern portion of a
low-level ridge. The new track forecast is similar to but slightly
east of the previous advisory track on days 2 and 3, and closely
follows a blend of the consensus models TVCN and GFEX.

Only slight strengthening is expected during the next day or so
due to baroclinic effects while Arthur undergoes extratropical
transition. Data from NOAA Buoy 44014, located west Arthur's
center, indicate that a cold front passed over that station around
2300 UTC, which would place the front about 50-75 nmi west of the
cyclone at this time. Therefore, a merger with the front is likely
during the next 12 hours. The system should begin to steadily
weaken shortly after 24 hours when Arthur will be moving over
SSTs near 20 deg C, and in conjunction with the aforementioned
decoupling of the circulations.

Dangerous coastal surf conditions and rip currents are expected to
continue along portions of the mid-Atlantic and southeast U.S.
coasts during the next couple of days. See products from your local
National Weather Service Forecast Office for more details.

WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Arthur was
located near latitude 36.4 North, longitude 72.4 West. Arthur is
moving toward the east-northeast near 15 mph (24 km/h), and this
motion is forecast to continue tonight. A turn toward the east is
expected on Tuesday. A slower motion toward the southeast or
south-southeast is expected to begin Tuesday night and continue
through Wednesday. On the forecast track, the center of Arthur will
continue to move out to sea away from the east coast of the United
States.

Recent satellite-derived wind data indicate that maximum sustained
winds have increased to near 60 mph (95 km/h) with higher gusts.
Although some slight strengthening is forecast during the
next day or so, Arthur is expected to lose its tropical
characteristics on Tuesday.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center. NOAA Buoy 44014 located about 100 miles (160 km)
west of Arthur's center recently measured a sustained wind of
38 mph (61 km/h) and a gust to 47 mph (76 km/h). Also, NOAA Buoy
41001 located about 120 miles (200 km) southeast of the center
recently measured a wind gust of 43 mph (69 km/h).

The estimated minimum central pressure is 991 mb (29.27 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Arthur are expected to affect portions
of the mid-Atlantic and southeast U.S. coasts during the next
day or two. These swells could cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Tropical Storm Arthur Discussion Number 9
NWS National Hurricane Center Miami FL AL012020
500 PM EDT Mon May 18 2020

Although the center of Arthur did not make landfall in the North
Carolina Outer Banks, it passed within about 20 n mi southeast of
Cape Hatteras around 1500 UTC. Tropical-storm-force wind gusts have
been reported at several automated observing sites on and near the
Outer Banks, with the highest sustained wind of 34 kt at Alligator
River Bridge earlier this afternoon. Deep convection continues over
the northeastern portion of Arthur's circulation, but visible
imagery has recently shown an increase in separation between
low-level center and the convective activity. This is the result of
increasing southwesterly shear and the beginning of the cyclone's
extratropical transition. The initial intensity remains 45 kt,
which was in agreement with the earlier aircraft data. As the
cyclone completes its extratropical transition, some strengthening
is forecast due to baroclinic processes. After 24 hours, little
change in strength is expected until the frontal gradients decrease
on Wednesday. The system should gradually spin down after that
time, and dissipate by late in the week.

The initial motion estimate is 045/14 kt. Arthur should continue
northeastward this evening, but is expected to turn eastward Tuesday
morning as the cyclone becomes embedded within the mid-latitude
westerlies. Troughing over the central and western Atlantic should
cause the Arthur to turn southeastward on Wednesday when the
steering flow becomes northwesterly. Little change was required to
the previous NHC official forecast and the updated track again lies
between the GFS, ECMWF, and the multi-model consensus.

Dangerous coastal surf conditions and rip currents are expected to
continue along portions of the mid-Atlantic and southeast U.S.
coasts during the next couple of days. See products from your local
National Weather Service Forecast Office for more details.

DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Arthur was
located near latitude 35.6 North, longitude 74.7 West. Arthur is
moving toward the northeast near 16 mph (26 km/h). This general
motion should continue today, followed by a turn toward the east on
Tuesday. A slower southeast or south-southeast motion is forecast
to begin Tuesday night and continue through Wednesday. On the
forecast track, the center of Arthur will continue to move away from
the North Carolina Outer Banks this afternoon. Arthur is then
forecast to turn away from the east coast of the United States
tonight and Tuesday.

Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. While some strengthening is forecast during the next 24
hours, Arthur is likely to lose its tropical characteristics late
tonight or Tuesday.

Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center, primarily over water to the east of the center. A
WeatherFlow observing site at Alligator River Bridge measured
sustained winds of 39 mph (63 km/h) and a gust to 46 mph (74 km/h)
earlier this afternoon. A wind gust to 42 mph (68 km/h) was recently
reported at Oregon Inlet.

The latest minimum central pressure estimated from reconnaissance
aircraft data is 993 mb (29.32 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area through this afternoon.

RAINFALL: Arthur is expected to produce total rain accumulations of
1 to 3 inches over coastal North Carolina through this afternoon,
with isolated maximum amounts of 5 inches.

SURF: Swells generated by Arthur are affecting portions of the
southeast U.S. coast and are expected to spread northward along the
U.S. mid-Atlantic coast during the next day or so. These swells
could cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

Tropical Storm Arthur Discussion Number 8
NWS National Hurricane Center Miami FL AL012020
1100 AM EDT Mon May 18 2020

Arthur has become a little better organized this morning with an
overall increase in convection and banding noted since overnight.
The first couple of reconnaissance aircraft passes through the
center have shown that the pressure has fallen to around 996 mb.
The plane has also reported several believable SFMR winds of 38-43
kt, and the anemometer on buoy 41025 at an elevation of only 4 m
has reported a peak 1-minute wind of 37 kt. Based on these data
the initial intensity is set at 45 kt.

The forward speed of Arthur has continued to increase and the
estimated motion is north-northeast at 14 kt. The cyclone should
turn northeastward later today and begin moving away from the North
Carolina Outer Banks as a mid-latitude trough approaches from the
west. By Tuesday, Arthur is forecast to turn eastward within the
mid-latitude westerlies. After that time, a deepening trough over
the central and western Atlantic is expected to cause the cyclone to
turn southeastward as the steering flow turns northwestward. The GFS
and ECMWF are now in relatively good agreement on this scenario and
the new NHC track forecast lies between those typically reliable
models and the multi-model consensus aids.

Although the vertical shear is increasing over the storm and it is
soon moving over cooler waters, some strengthening due to baroclinic
process is predicted over the next 24 hours. The storm should merge
with a frontal boundary late tonight or early Tuesday which will
complete Arthur's transition to an extratropical cyclone. By
Wednesday, the post-tropical cyclone should begin to weaken as the
frontal gradients decrease. The post-tropical cyclone should
dissipate in about 96 h.


Key Messages:

1. A Tropical Storm Warning is in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there today.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward along the southeast U.S. coast to the
mid-Atlantic states during the next couple of days. See products
from your local National Weather Service Forecast Office for more
details.

DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Arthur was
located near latitude 35.1 North, longitude 75.2 West. Arthur is
moving toward the north-northeast near 16 mph (26 km/h). A turn
toward the northeast is expected later today, followed by a turn
toward the east on Tuesday. A slower southeast or south-southeast
motion is forecast to begin Tuesday night and continue through
Wednesday. On the forecast track, the center of Arthur will begin
moving away from the North Carolina Outer Banks this afternoon.
Arthur is then forecast to turn away from the east coast of the
United States tonight and Tuesday.

Reports from an Air Force Reserve reconnaissance aircraft indicate
that the maximum sustained winds are near 50 mph (85 km/h) with
higher gusts. Some additional strengthening is forecast during the
next 24 hours. Little change in strength is expected Tuesday night
and Wednesday.

Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center, primarily over water to the east of the center.
NOAA buoy 41025 located about 20 miles (30 km) southeast of Cape
Hatteras, North Carolina, reported sustained winds of 43 mph (68
km/h) with a gust to 49 mph (80 km/h).

The latest minimum central pressure estimated from reconnaissance
aircraft data is 996 mb (29.42 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area through early afternoon.

RAINFALL: Arthur is expected to produce total rain accumulations of
1 to 3 inches over coastal North Carolina through this afternoon,
with isolated maximum amounts of 5 inches.

SURF: Swells generated by Arthur are affecting portions of the
southeast U.S. coast and are expected to spread northward along the
U.S. mid-Atlantic coast during the next day or so. These swells
could cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

Tropical Storm Arthur Discussion Number 7
NWS National Hurricane Center Miami FL AL012020
500 AM EDT Mon May 18 2020

Arthur remains poorly organized in both satellite and radar imagery
this morning, with the low-level center located near the
southwestern edge of a complex of ragged convective bands. Surface
observations from buoys off of the North Carolina coast suggest the
central pressure has fallen a little since the last aircraft fix,
so the intensity will be held at 40 kt for this advisory. The next
aircraft is scheduled to reach Arthur between 11-12Z.

Arthur's forward speed has increased with the initial motion now
020/12. A baroclinic trough and associated surface front
approaching from the west should cause Arthur to turn northeastward
during the next several hours, with the forecast track showing the
center passing near or just offshore of the North Carolina Outer
Banks. By Tuesday and Tuesday night, Arthur will be entering the
strong mid-latitude Westerlies, which will steer cyclone eastward
for a day or two. After that time, Arthur or its remnants should
turn southeastward and southward on the southwest side of a
deep-layer trough over the central Atlantic. The latest guidance
is showing a more southward motion after 60 h than seen previously,
and the new forecast track is also nudged southward during that
time.

Arthur is moving near and almost parallel to the Gulf Stream, and
the warm water could allow some strengthening before southwesterly
shear increases significantly later today. The cyclone should merge
with a frontal system and become extratropical in the 24-36 h
period, with the global models indicating some increase in the winds
north of the center as this occurs. The intensity forecast calls
for Arthur to reach a 50 kt intensity in 36 h as an extratropical
low in best agreement with the GFS model. After 48 h, the system
should decay, and the global models suggest it should dissipate in
the 96-120 h period. The new intensity forecast has only minor
tweaks from the previous forecast.


Key Messages:

1. A Tropical Storm Warning is in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there today.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward along the southeast U.S. coast to the
mid-Atlantic states during the next couple of days. See products
from your local National Weather Service Forecast Office for more
details.

Tropical Storm Arthur Discussion Number 6
NWS National Hurricane Center Miami FL AL012020
1100 PM EDT Sun May 17 2020

Arthur's appearance in radar and satellite imagery has degraded
significantly since the previous advisory with very little
convective banding features present now. However, an Air Force
Reserve reconnaissance aircraft investigating the cyclone late this
afternoon and early has found maximum 850-mb flight-level winds of
46 kt in the eastern quadrant along with reliable SFMR surface wind
speeds of 36-38 kt, plus a central pressure of 1003 mb. Based on
these data, the initial intensity has been held at 40 kt for this
advisory since higher wind speeds could be present within areas of
convection north of the center that were not sampled.

Aircraft and satellite fixes indicate that Arthur has continued to
move north-northeastward or 020/09 kt. The cyclone is forecast to
accelerate northeastward on Monday ahead of an approaching shortwave
trough and frontal system, and remain just offshore of the North
Carolina Outer Banks. By Tuesday night, Arthur will be entering the
strong mid-latitude Westerlies, which will steer cyclone eastward
and also induce extratropical transition when the cyclone merges
with the aforementioned frontal system. The new NHC track guidance
is tightly clustered about the previous forecast track, so no
significant cross-track changes were required. However, some slight
changes to the forward were required on days 2 and 3, and the new
NHC track forecast now shows Arthur moving a little faster to the
east and southeast on those days.

Arthur is currently moving over the warmest waters in the Gulfstream
where ocean temperatures are 26-26.5 deg C. However, some mid-level
shear undercutting the otherwise upper-level outflow pattern,
coupled with the entrainment of dry mid-level air has disrupted the
overall convective pattern. These unfavorable conditions should
continue for the next coupe of days, with only intermittent bursts
of deep convection occuring near the center until Arthur passes
northeast of the Outer Banks by late Monday. Thereafter, baroclinic
effects along with extratropical transition are expected to cause
some further strengthening before weakening begins late Tuesday and
on Wednesday. The official intensity forecast follows a blend of the
intensity consensus model IVCN, and the GFS and ECMWF model
forecasts.


Key Messages:

1. A Tropical Storm Warning is in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there on Monday.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward along the southeast U.S. coast to the
mid-Atlantic states during the next couple of days. See products
from your local National Weather Service Forecast Office for more
details.

--------------------
CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Surf City to Duck NC
* Pamlico and Albemarle Sounds

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 hours.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Tropical Storm Arthur was
located by an Air Force Reserve reconnaissance aircraft near
latitude 31.8 North, longitude 77.0 West. Arthur is moving toward
the north-northeast near 9 mph (15 km/h). A turn toward the
northeast with an increase in forward speed is forecast to occur
later tonight or on Monday. A turn toward the east is expected on
Tuesday. On the forecast track, the center of Arthur will remain
well offshore of the coasts of Georgia and South Carolina tonight,
and then move near or just east of the coast of North Carolina on
Monday. Arthur is forecast to turn away from the east coast of the
United States Monday night and Tuesday.

Maximum sustained winds are near 45 mph (75 km/h) with higher
gusts. Some gradual strengthening is forecast during the next day or
so. Arthur is likely to lose tropical characteristics on Tuesday.

Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center.

The minimum central pressure recently measured by the
reconnaissance aircraft was 1004 mb (29.65 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area on Monday.

RAINFALL: Arthur is expected to produce total rain accumulations of
1 to 3 inches over coastal North Carolina tonight and Monday,
with locally higher amounts.

SURF: Swells generated by Arthur are affecting portions of the
southeast U.S. coast and are expected to spread northward along the
U.S. mid-Atlantic coast during the next day or two. These swells
could cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

Tropical Storm Arthur Discussion Number 5
NWS National Hurricane Center Miami FL AL012020
500 PM EDT Sun May 17 2020

Arthur's satellite presentation has not changed much since the
previous advisory. There are still some fragmented convective
bands over the eastern portions of the circulation, but convective
activity remains limited over the western half of the storm. A
late-arriving ASCAT overpass from around the time of the previous
advisory revealed somewhat lower wind speeds than reported by
this morning's reconnaissance aircraft. This could be the result
of the convection becoming more fragmented after the aircraft
sampled that portion of the storm or related to the low bias of
the ASCAT instrument. Regardless, the initial intensity remains a
possibly generous 40 kt for now. Another reconnaissance aircraft
is scheduled to investigate Arthur this evening.

Arthur is forecast to remain within a low wind shear environment
and over marginally warm sea surface temperatures through early
Monday. These conditions favor some strengthening, however the
sprawling structure of the cyclone and nearby dry mid-level air are
likely to temper any increase in wind speed. After 36-48 hours,
baroclinic forcing is expected to help the post-tropical cyclone
maintain its intensity. Later in the period, the frontal
gradients decrease which should cause weakening.

Recent satellite fixes show that the Arthur is still moving
north-northeastward at about 8 kt. The tropical storm should begin
to accelerate northeastward overnight as a mid-level trough moves
into the eastern United States. By Tuesday night, the steering
flow is expected to become westerly which should cause Arthur to
turn eastward, then southeastward later in the forecast period.
The lastest dynamical track guidance has come into a little better
agreement through 36-48 hours with the GFS and ECMWF converging on
the previous NHC track. As a result, little change was needed to
the first couple of days of the earlier NHC track forecast. After
that time, most of the guidance has trended toward a faster
eastward and east-southeastward motion, and the NHC forecast has
been adjusted accordingly in that direction as well.


Key Messages:

1. A Tropical Storm Warning is in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there on Monday.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward along the southeast U.S. coast to the
mid-Atlantic states during the next couple of days. See products
from your local National Weather Service Forecast Office for more
details.

Tropical Storm Arthur Discussion Number 4
NWS National Hurricane Center Miami FL AL012020
1100 AM EDT Sun May 17 2020

Visible satellite imagery reveals a couple of convective bands over
the eastern semicircle of the tropical storm, but convection is
sparse over the western portion of the circulation. The latest
reports from an Air Force reconnaissance aircraft show peak 925-mb
flight-level winds of 48 kt, and believable SFMR winds of 35-40 kt.
On this basis, the initial wind speed has been increased to 40 kt.
The plane has reported a minimum pressure of 1002-1003 mb, which is
down a few millibars from the previous flight.

Arthur has a little more than 24 hours in which to gradually
strengthen. The storm will be traversing the relatively warm
waters of the Gulf stream, and the vertical shear is forecast to
remain low through early Monday. After that time, increasing shear
and cooler sea surface temperatures should put a halt to the
tropical cyclone strengthening processes. Baroclinic forcing is
likely to help the post-tropical cyclone maintain its strengthen
through extratropical transition. Later in the forecast period,
the global model guidance shows weakening as the frontal gradients
decrease.

The storm is moving north-northeastward or 015/8 kt. Arthur is
expected to begin moving a little faster later today and tonight as
a mid-level trough approaches the eastern United States. Later in
the forecast period, the cyclone should turn eastward within the
westerly steering flow. Although the dynamical models are in
agreement on the overall scenario, there remains some spread as to
how close the center of Arthur will track to the North Carolina
Outer Bands. The GFS and HWRF remain along the western side of the
guidance while the ECMWF and UKMET bracket the eastern side. The
NHC track lies near the model consensus and little change was
required to the previous track through 36-48 hours. After that
time, the track guidance spread increases with the ECMWF showing a
much faster east-southeastward motion than the GFS. The NHC
forecast remains near the consensus after 48 hours, but there is
less confidence in that portion of the track prediction.


Key Messages:

1. A Tropical Storm Warning is in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there on Monday.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward along the southeast U.S. coast to the
mid-Atlantic states during the next couple of days. See products

...ARTHUR MOVING NORTH-NORTHEASTWARD...


SUMMARY OF 800 AM EDT...1200 UTC...INFORMATION
----------------------------------------------
LOCATION...30.3N 77.4W
ABOUT 355 MI...575 KM SSW OF CAPE HATTERAS NORTH CAROLINA
MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
PRESENT MOVEMENT...NNE OR 15 DEGREES AT 9 MPH...15 KM/H
MINIMUM CENTRAL PRESSURE...1002 MB...29.59 INCHES


WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

None

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Surf City to Duck NC
* Pamlico and Albemarle Sounds

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 to 36 hours.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Arthur was
located near latitude 30.3 North, longitude 77.4 West. Arthur is
moving toward the north-northeast near 9 mph (15 km/h). A turn
toward the northeast with an increase in forward speed is expected
during the next 24 to 48 hours. On the forecast track, Arthur will
remain well offshore the east coast of Florida, Georgia, and South
Carolina today, and then move near or just east of the coast of
North Carolina on Monday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Some strengthening is forecast during the next 48 hours.
Arthur is likely to lose its tropical characteristics on Tuesday.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.

The estimated minimum central pressure is 1002 mb (29.59 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area on Monday.

RAINFALL: Arthur is expected to produce total rain accumulations of
1 to 3 inches over coastal North Carolina tonight and Monday,
with locally higher amounts.

SURF: Swells generated by Arthur are affecting portions of
the southeast U.S. coast and are expected to spread northward along
the U.S. mid-Atlantic coast during the next day or two. These
swells could cause life-threatening surf and rip current conditions
across much of the U.S. southeast and mid-Atlantic coasts. Please
consult products from your local weather office.

Tropical Storm Arthur Discussion Number 3
NWS National Hurricane Center Miami FL AL012020
500 AM EDT Sun May 17 2020

Arthur has not changed much in organization overnight. The storm
features a large curved convective band over the eastern semicircle
of the circulation, and the low-level center appears to be exposed
to the west of that band. The intensity is held at 35 kt in
agreement with a subjective Dvorak estimate from TAFB and ADT
estimates from UW-CIMSS. An Air Force Hurricane Hunter aircraft is
scheduled to investigate the cyclone around 12Z which should provide
a good estimate of Arthur's intensity.

Although Arthur will be crossing back over the Gulf Stream tonight
and Monday, vertical shear is forecast to steadily increase during
that time. With these counteracting influences on intensity
change, only slight strengthening is anticipated during the next
24-36 hours. The official forecast is close to the model consensus
and is similar to the previous one. In 2-3 days, some strengthening
due to baroclinic processes is possible, since the global models
depict extratropical transition around that time. Later in
the forecast period, the dynamical guidance shows weakening as the
frontal gradients decrease.

The storm has been moving a little to the left of the previous
estimates and the motion is now around 015/8 kt. An approaching
mid-level trough over the eastern U.S. should cause the cyclone to
accelerate northeastward during the next 48 hours or so. Later in
the forecast period, Arthur or its post-tropical remnants should
turn eastward within a general westerly flow field. There has been
a bit of a westward shift in much of the track guidance for the
next 1-2 days, which has necessitated a leftward adjustment of the
official forecast track. Since the new NHC forecast is now closer
to the North Carolina Outer Banks, the Tropical Storm Watch has
been changed to a Tropical Storm Warning for that area.

Key Messages:

1. A Tropical Storm Warning is now in effect for a portion of the
North Carolina coast. Tropical-storm-force winds and heavy rains
are expected there on Monday.

2. Dangerous coastal surf conditions and rip currents are expected
to spread northward from Florida to the mid-Atlantic states during
the next few days. See products from your local National Weather
Service Forecast Office for more details.

Post-Tropical Cyclone Lorenzo Discussion Number 41
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Wed Oct 02 2019

Lorenzo has completed its transition into a powerful extratropical
cyclone and this will be the last NHC advisory on this system. The
center has become exposed on the southwestern edge of the cloud
shield, and recent ASCAT data indicate that the system has acquired
frontal features. The initial intensity is set at 70 kt, which is
a little above the scatterometer data since there is typically a
low bias in that instrument at these wind speeds. The global
models suggest that the post-tropical cyclone will only gradually
weaken during the next 24 to 36 hours as it approaches Ireland. A
faster rate of weakening is expected Thursday night and Friday when
the cyclone moves southeastward over Ireland and the United Kingdom.
The low should dissipate over southeastern England by late Friday.

The cyclone continues to move rapidly northeastward or 040/37 kt,
and this general motion should continue into Thursday. After that
time, the cyclone is expected to turn eastward and then
southeastward within an area of weaker westerly flow. The global
model guidance is in good agreement, and the NHC track forecast is
in closest to the ECMWF model.

Future hazard information on Lorenzo for Ireland and the United
Kingdom can be found in products issued by Met Eireann and the
United Kingdom Met Office.

Local forecasts and warnings for Ireland can be found on the
website of Met Eireann, the Irish Meteorological Service, at

DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Lorenzo was
located near latitude 43.0 North, longitude 28.0 West. Lorenzo is
moving toward the northeast near 43 mph (69 km/h). A continued fast
motion toward the northeast is expected through Thursday morning.
The cyclone is forecast to slow down and turn eastward by Thursday
night. On the forecast track, the center of Lorenzo will continue
moving away from the Azores today, and move near Ireland Thursday
evening.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Only slow weakening is forecast during the next 48 hours,
and Lorenzo is expected to be a strong extratropical cyclone when it
approaches Ireland Thursday afternoon and evening.

Hurricane-force winds extend outward up to 150 miles (240 km) from
the center and tropical-storm-force winds extend outward up to 390
miles (630 km). As Lorenzo passed near the western Azores earlier
this morning, a sustained wind of 74 mph (119 km/h) with a gust to
101 mph (163 km/h) was reported on Corvo Island. A wind gust of 90
mph (145 km/h) was observed on Faial Island, and a gust to 88 mph
(142 km/h) was reported on Flores Island.

The estimated minimum central pressure is 960 mb (28.35 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Lorenzo can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml

WIND: Winds will continue to decrease across the Azores this
morning.

RAINFALL: Lorenzo is expected to produce additional rain
accumulations of less than 1 inch (25 mm) through this morning.
Isolated storm total amounts of 2 inches (50 mm) are possible in the
western Azores.

SURF: Swells generated by Lorenzo have spread across much of the
North Atlantic basin, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, the Azores, and portions of the coast of Europe.
These swells are likely to cause life-threatening surf and rip

Hurricane Lorenzo Discussion Number 40
NWS National Hurricane Center Miami FL AL132019
500 AM AST Wed Oct 02 2019

Lorenzo passed near Flores in the Azores a few hours ago where
hurricane-force winds, at least in gusts, were observed. Winds
are now decreasing across those islands. The current intensity
estimate, 75 kt, assumes only slow weakening since late yesterday.
The cloud pattern is becoming increasingly asymmetric in
appearance, suggestive that transition to an extratropical cyclone
is well underway. The global models indicate that Lorenzo will soon
become embedded in a frontal zone, and simulated satellite imagery
from the ECMWF and GFS models show an extratropical-looking cloud
pattern later today. The official forecast calls for a gradual
weakening trend over the next couple of days and is above the
intensity guidance. Although the system is forecast to become
extratropical in 12 hours, it is still likely be a fairly vigorous
cyclone when it reaches Ireland late Thursday. After crossing
England, the low is likely to dissipate over continental Europe.

Lorenzo accelerated significantly late Tuesday, and the motion is
rapidly northeastward, or 040/37 kt. Over the next day or so,
the system should continue to move northeastward ahead of a large
mid-tropospheric trough over the north Atlantic. Then, the cyclone
is forecast to turn eastward and a little south of eastward in the
weaker westerly flow ahead of the trough. The official track
forecast is close to the model consensus, but leans a bit toward
the ECMWF forecast.

Lorenzo's expansive circulation is producing very large seas over
the north Atlantic. Full information can be found in High Seas
Forecasts from the following agencies:

The NOAA Ocean Prediction Center under AWIPS header NFDHSFAT1, WMO
header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php

Key Messages:

1. Winds across the Azores will continue to decrease, and watches
and warnings for those islands will likely be discontinued later
today.

2. Lorenzo is expected to be a strong extratropical cyclone when
it approaches Ireland Thursday afternoon or evening.

2. Swells generated by Lorenzo have spread across much of the
North Atlantic, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, and portions of the coast of Europe. These swells
will produce life-threatening surf and rip currents.

of 1 to 2 inches (25 to 50 mm) over the western Azores and up to 1
inch (25 mm) over the central Azores through Wednesday.

SURF: Swells generated by Lorenzo have spread across much of the
North Atlantic basin, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, the Azores, and portions of the coast of Europe.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather

Hurricane Lorenzo Discussion Number 39
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Tue Oct 01 2019

Lorenzo's convective cloud pattern has eroded significantly during
the past 6 hours, with an eye no longer evident in infrared
satellite imagery. However, a ragged remnant eye feature is still
present in passive microwave imagery, and that data indicates that
the mid- and upper-level circulations are tilted about 15-20 nmi
northeast of the low-level center due to strong southwesterly
vertical wind shear of 25-30 kt. Satellite intensity estimates have
also decreased and now support around 75 kt. However, the intensity
is being maintained at 85 kt due to Lorenzo's faster forward speed,
which is now about 10 kt more than it was on the previous advisory,
offsetting the possible decrease in the tangential winds. The 64-,
50-, and 34-kt wind radii had to once again be expanded in nearly
every quadrant, but especially to the southeast, based on a 2305 UTC
ASCAT-B overpass. The larger wind field is now expected to result in
sustained hurricane-force winds occurring across portions of the
western and central Azores on Wednesday morning.

Despite the hurricane's extremely large size, Lorenzo has continued
to accelerate northeastward and is now moving 045/35 kt. Lorenzo's
forward speed should gradually level off near 40 kt on Wednesday,
and then gradually begin to decrease by Thursday morning when the
cyclone turns more eastward toward Ireland. By late Thursday,
post-tropical Lorenzo is forecast to turn east-southeastward,
crossing Ireland and southern England. The latest NHC model guidance
is tightly packed about the previous forecast track, so only minor
tweaks were required, and new advisory lies close to an average of
the various consensus model forecast tracks.

Lorenzo is currently moving over sea-surface temperatures (SST) near
24 deg C, and that isn't taking into account any cold upwelling that
is likely occurring beneath the very large hurricane. With only
colder water ahead of the cyclone, coupled with vertical shear
increasing to more than 40 kt by 12 hours, rapid transition to a
powerful post-tropical/extratropical cyclone is expected shortly
after Lorenzo passes the Azores. However, only gradual weakening is
foreast during the next 24 hours due to baroclinic interaction with
an upper-level trough and frontal system. After that time, a more
rapid rate of weakening is expected when Lorenzo will be moving over
Ireland and England.

Lorenzo's expansive circulation is producing very large seas over
the north Atlantic. Full information can be found in High Seas
Forecasts from the following agencies:

The NOAA Ocean Prediction Center under AWIPS header NFDHSFAT1, WMO
header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php

Key Messages:

1. Lorenzo is expected to bring hurricane- and tropical-storm-force
winds to the Azores beginning within the next couple of hours, with
those dangerous conditions continuing into Wednesday afternoon.
Hurricane and Tropical Storm Warnings are in effect for the Azores.

2. Swells generated by Lorenzo have spread across much of the
North Atlantic, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, and portions of the coast of Europe. These swells
will produce life-threatening surf and rip currents.

Hurricane Lorenzo Discussion Number 38
NWS National Hurricane Center Miami FL AL132019
500 PM AST Tue Oct 01 2019

The eye of Lorenzo, while still evident in both visible and infrared
satellite imagery, has become smaller and slightly less distinct
this afternoon, but the overall structure of the hurricane has not
changed much since the previous advisory. Objective Dvorak
T-numbers crept up this morning when the eye cleared for a couple
of hours and are somewhat higher than the latest subjective
estimates from TAFB and SAB. A blend of these estimates remains
around 85 kt, and this is the value used as the initial wind speed
for this advisory. Lorenzo is heading toward colder waters and an
area of increasing vertical wind shear. However, since the wind
field of the hurricane is quite large, only gradually weakening is
foreast during the next 12 to 24 hours. After that time, Lorenzo
is forecast to merge with a front and become a strong extratropical
low over the northeastern Atlantic. The global models indicate
that the post-tropical low will weaken more quickly when it moves
near Ireland and Great Britain in 2 to 3 days.

Lorenzo continues to accelerate northeastward, with an initial
motion estimate of 040/25 kt. The forward speed of the hurricane
is predicted to increase further overnight and on Wednesday as it
is steered northeastward ahead of a mid-latitude trough over the
central Atlantic. By late Thursday, the post-tropical cyclone
should slow down and turn eastward or east-southeastward within the
low-level westerly flow. The track has continued to bend to the
right beyond 48 hours, and the official forecast has once again
been adjusted southward and eastward at that time period. The new
NHC track forecast is in good agreement with the latest ECMWF model.

Lorenzo is producing very large seas over the north Atlantic. Full
information can be found in High Seas Forecasts from the following
agencies:

The NOAA Ocean Prediction Center under AWIPS header NFDHSFAT1, WMO
header FZNT01 KWBC, and online at

Key Messages:

1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning tonight, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are in effect for the Azores.

2. Swells generated by Lorenzo have spread across much of the
North Atlantic, and are affecting the east coast of the United
States, Atlantic Canada, the Bahamas, portions of the Greater and
Lesser Antilles, and portions of the coast of Europe. These swells
will produce life-threatening surf and rip currents.

Hurricane Lorenzo Discussion Number 37
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Tue Oct 01 2019

Lorenzo remains a well organized hurricane this morning as it heads
toward the Azores. The eye has made a reappearance in infrared
satellite imagery, and the cloud tops associated with the
surrounding ring of convection have cooled. The advisory intensity
remains 85 kt, which is the consensus of the latest objective
and subjective satellite intensity estimates that range from 77 to
90 kt. Lorenzo is expected to maintain its intensity today, but it
will be moving over progressively colder waters and into an area of
increasing shear, which should cause gradual weakening by
Wednesday. The global models show the hurricane merging with a
frontal zone, and becoming extratropical in about 36 hours. The
extratropical low should weaken in a couple of days while it moves
near Ireland and Great Britain, and then it is forecast to dissipate
over Europe by 96 hours.

Lorenzo is moving northeastward at 22 kt. The hurricane should
continue to accelerate northeastward ahead of a mid-latitude trough
over the central Atlantic during the next day or two. After that
time, the cyclone is predicted to decelerate and turn
east-northeastward or eastward within the low-level westerly flow.
The global model guidance is in excellent agreement through the
first 36-48 hours, and has also come into somewhat better agreement
on the eastward turn later in the period. The updated NHC track has
been adjusted southeastward at 72 hours, but still lies north of the
multi-model consensus. An additional southward and eastward
adjustment of the post-tropical cyclone's track near Ireland
and the United Kingdom may be necessary in future advisories.

Lorenzo is producing huge seas over the north Atlantic. Full
information on the High Seas Forecasts can be found at the Ocean
Prediction Center under AWIPS header NFDHSFAT1, WMO header FZNT01
KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php.
The UK Met Office also has information in High Seas Forecasts issued
by under WMO header FQNT21 EGRR and on the web at
http://www.metoffice.gov.uk/public/weather/marine-high-seas/


Key Messages:

1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning tonight, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are in effect for the Azores.

2. Swells generated by Lorenzo have spread across much of the

tightly curved convective bands. The upper-level outflow remains
quite well-defined. The advisory intensity, 85 kt, is a blend of
subjective Dvorak estimates from TAFB and SAB along with ADT values
from UW-CIMSS. Sea-surface temperatures beneath the cyclone are
likely to fall below 20 deg C within 36 hours, along with a large
increase in vertical shear. Since Lorenzo has such a large
circulation, it will probably be slow to weaken, however. In 48
hours or less, the global models show the system merging with a
frontal zone, indicating the transition to an extratropical
cyclone. The NHC intensity forecast is on the high side of the
numerical guidance but still weakens the cyclone below hurricane
strength when it nears Ireland and Great Britain. By 96 hours, the
cyclone should dissipate over Europe.

The hurricane continues to accelerate, and is now moving
northeastward near 19 kt. Continued acceleration on the southeast
and east side of a large mid-tropospheric trough over the central
north Atlantic should occur over the next day or two. In 72 hours
or so, the cyclone is expected to turn east-northeastward while
moving in the westerly flow ahead of the north Atlantic trough.
There is still significant track model divergence around this time,
and the official 3-day forecast is somewhat southeast of the model
consensus. This leans toward the latest ECMWF solution, which
continues to be on the southeast side of the track guidance
envelope.

Lorenzo is producing huge seas over the north Atlantic. Full
information on the High Seas Forecasts can be found at the Ocean
Prediction Center under AWIPS header NFDHSFAT1, WMO header FZNT01
KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php.

Key Messages:

1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning tonight, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are in effect for the Azores.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents,
especially across the Azores.

Hurricane Lorenzo Discussion Number 35
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Mon Sep 30 2019

Lorenzo has not changed appreciably during the past several hours
on satellite imagery, with an eye still present along with a large
cloud shield in the northeastern quadrant. Dvorak estimates remain
near 90 kt so that will be the initial wind speed. The initial
wind field has also grown according to the latest scatterometer
data, and that is reflected in the wind radii analyses.

The hurricane is now moving faster and has turned northeastward at
about 17 kt. Lorenzo should continue to accelerate to the northeast
during the next couple of days ahead of a large mid- latitude
trough, and the model guidance remains in tight agreement taking the
hurricane near the western Azores. The longer-range future of
Lorenzo is a little clearer tonight as the global models are in much
better agreement on the cyclone turning east- northeastward close to
Ireland and then eastward across Great Britain, dissipating over
western Europe by 96 h. The new forecast is shifted southward, and
is close to a blend of the latest UKMET/ECMWF and GFS solutions.

Lorenzo is forecast to slowly weaken tomorrow due to the cyclone
moving over progressively cooler waters. Extratropical transition
should occur by 48 hours, and there is unanimous global model
agreement on Lorenzo keeping much of its strength through that time.
Weakening is then anticipated while the low approaches Ireland and
the U.K., although the wind speed forecast at 72 hours is
deceptively low since the radius of maximum winds is possibly
already onshore.

It is also worth mentioning that there will be some enormous seas on
the eastern side of Lorenzo. The hurricane will be accelerating to
the northeast in the same general direction for a couple of days.
Combined with the large size and intensity, this is a recipe for an
amplified wave field on the eastern side due to a phenomenon called
trapped-wave fetch. Full information on the High Seas Forecasts can
be found at the Ocean Prediction Center under AWIPS header
NFDHSFAT1, WMO header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php.

can be found up to 90 n mi from the center. A cloud-covered eye has
been apparent throughout the day and cloud-top temperatures
surrounding the eye have remained fairly consistent. The most recent
Dvorak CI values from TAFB and SAB suggest Lorenzo is maintaining
its strength at 90 kt, which will remain the initial intensity for
this advisory. A drifting NOAA buoy near the eyewall of Lorenzo
recently reported a pressure of 964.8 mb, supporting the minimum
central pressure of 957 mb.

Lorenzo continues moving north-northeastward at 13 kt, around the
northwestern periphery of a subtropical ridge to its southeast. Over
the next couple of days Lorenzo will be accelerated northeastward by
increasing southwesterly flow ahead of a mid-latitude trough
amplifying across the central Atlantic. This motion should take the
core of Lorenzo near the western Azores late Tuesday and early
Wednesday. The forecast track confidence remains high through 72
hours. After that time, global models have come into a little better
agreement on the future track of Lorenzo, with a turn to the right
toward Ireland or the U.K. as a weakening extratropical low. The
official forecast track is just a little to the right of the
previous one and lies near the consensus aids.

The environment surrounding Lorenzo is not expected to change much
through tonight, and therefore the intensity should remain fairly
steady. On Tuesday, the hurricane should begin gradually weakening
as drier air entrains into the circulation and the system moves over
progressively cooler waters. By 48 hours, the interaction with the
approaching trough, an associated cold front, and very strong
southwesterly shear will help transition Lorenzo into an
extratropical low. This transition is expected to be complete by 72
hours. The low is then expected to weaken and dissipate shortly
after 96 hours. The official forecast was increased through
the first 48 hours to reflect a more steady intensity in the near
term, and then is blended close to the previous forecast after that
time.

Key Messages:

1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning Tuesday night, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are now in effect for the Azores.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents.

36 hours before the anticipated first occurrence of
tropical-storm-force winds, conditions that make outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Hurricane Lorenzo was
located near latitude 30.3 North, longitude 42.4 West. Lorenzo is
moving toward the north-northeast near 15 mph (24 km/h). A turn to
the northeast is expected later today, with an increasing forward
speed tonight through Wednesday. On the forecast track, the center
of Lorenzo is expected to pass near the western Azores early on
Wednesday.

Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts. Gradual weakening is expected through Wednesday. Lorenzo is
expected to transition to an extratropical low by Thursday.

Lorenzo is a large hurricane, with hurricane-force winds extending
outward up to 90 miles (150 km) from the center and
tropical-storm-force winds extending outward up to 255 miles (405
km).

The estimated minimum central pressure is 962 mb (28.41 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Lorenzo can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml

WIND: Hurricane conditions are expected within the hurricane warning
area early Wednesday morning, with tropical storm conditions
beginning Tuesday night. Tropical storm conditions are expected in
the tropical storm warning area by early Wednesday.

RAINFALL: Lorenzo is expected to produce total rain accumulations
of 2 to 4 inches over much of the western Azores and around 1 inch
over the central Azores Tuesday and Wednesday. This rainfall could
cause life-threatening flash flooding in the western Azores.

SURF: Swells generated by Lorenzo are spreading across much of the
North Atlantic basin. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Hurricane Lorenzo Discussion Number 33
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Mon Sep 30 2019

Lorenzo continues to maintain its strength. A cloud filled eye is
evident in infrared satellite imagery, while convection is
attempting to wrap around a break in the southern portion of the
hurricane. This is indicating that for the time being, the cyclone
is fighting off some of the dry air entraining into it from the
southwest. The subjective Dvorak intensity estimates from TAFB and
SAB remain at 90 kt, which will be the initial intensity for this
advisory.

Lorenzo continues north-northeastward, now at 13 kt, around the
northwestern periphery of a subtropical ridge. Over the next couple
of days Lorenzo will be accelerated northeastward by increasing
southwesterly flow ahead of a mid-latitude trough amplifying across
the central Atlantic. This motion should take the core of Lorenzo
near or just west of the western Azores late Tuesday and early
Wednesday. The forecast track confidence is high through 72 hours,
but decreases significantly thereafter, as forecast models continue
to differ on their handling of the steering flow. By that time, the
steering flow may break down as the trough to the west of Lorenzo
de-amplifies, while an extratropical low quickly approaches from the
west. Some of the forecast models turn Lorenzo north ahead of the
approaching low as they begin to interact, other solutions turn
Lorenzo or its remnants to the east in the westerlies, with
limited interaction with this low. The official forecast track is
very close to the previous one and to the consensus aids, which lies
in between these two scenarios.

Lorenzo should gradually weaken over the next couple of days while
drier air continues to get pulled into the circulation and the
system moves over progressively cooler waters. After 48 hours, the
interaction with the approaching trough, an associated cold front,
and very strong southwesterly shear will help transition Lorenzo
into an extratropical low. This transition is expected to be
complete by 72 hours. The low is then expected to either dissipate
or become absorbed by another extratropical low by day 5. The
official forecast intensity is very similar to the previous one,
and is in good agreement with the consensus aids.

Key Messages:

1. Lorenzo is expected to bring hurricane and tropical storm force
winds to the Azores beginning Tuesday night, and these conditions
will continue into Wednesday. Hurricane and Tropical Storm Warnings
are now in effect for the Azores.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents.

Hurricane Lorenzo Discussion Number 32
NWS National Hurricane Center Miami FL AL132019
500 AM AST Mon Sep 30 2019

The satellite presentation of Lorenzo has generally changed little
during the last several hours. The hurricane continues to maintain
a well-defined inner core with a ragged cloud-filled eye. The
outer bands are well established to the north and east of the
center, but are restricted on the south side of the circulation due
to some southwesterly shear and drier air being wrapped into that
portion of the cyclone. The initial intensity estimate is set at 90
kt based on T5.0/90 kt Dvorak classifications from TAFB and SAB.

Lorenzo is moving north-northeastward at 11 kt through a break in
the Atlantic subtropical ridge. The models generally agree that
Lorenzo should pick up forward speed and move northeastward
during the next day or two as a trough amplifies over the central
Atlantic. This flow should take the core of Lorenzo near or to
the west of the western Azores late Tuesday and early Wednesday.
After that time, the spread in the guidance increases with several
of the models including the GFS, HWRF, and HMON showing Lorenzo
turning north-northeastward or northward as it moves around
the east side of a large extratropical low. The new ECMWF run has
shifted closer to the GFS/HWRF/HMON solutions, but it still is
considerably to the east of those models as it shows less
interaction with the extratropical low. The NHC track forecast has
been adjusted a little to the left to come into better agreement
with the latest consensus aids. Although the spread in the models
is not as large as it was yesterday, the forecast beyond 48 hours is
still of low confidence given the uncertainty in the longer-term
steering flow.

The intensity forecast appears to be more straightforward than the
track forecast. The bulk of the guidance shows the hurricane
maintaining its intensity or weakening slightly during the next day
or two while it remains over relatively warm waters and in moderate
wind shear conditions. It seems likely that Lorenzo will
be a significant hurricane when it passes near the Azores in about
2 days. After that time, more notable weakening should occur due to
a significant drop off in SSTs, drier air, and much stronger shear.
In fact, these conditions should ultimately lead to extratropical
transition, which is expected to be complete by 72 hours.
Dissipation is now predicted to occur by day 5 following the global
model guidance.

Key Messages:

1. Lorenzo is a large and powerful hurricane, and its hurricane-
and tropical-storm-force wind fields are expected to expand further
during the next few days. Hurricane and Tropical Storm Watches
are in effect for the Azores, and Hurricane and Tropical Storm
Warnings could be required later today for those islands.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents.

DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Hurricane Lorenzo was
located near latitude 28.1 North, longitude 43.2 West. Lorenzo is
moving toward the north-northeast near 10 mph (17 km/h). A turn to
the northeast is expected later today with a gradual increase in
forward speed through Wednesday. On the forecast track, the center
of Lorenzo is expected to pass near the Azores early on Wednesday.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Some weakening is forecast during the next 48 hours, but
Lorenzo is forecast to remain a large and powerful hurricane while
it passes near the Azores.

Hurricane-force winds extend outward up to 90 miles (150 km) from
the center and tropical-storm-force winds extend outward up to 255
miles (405 km).

The estimated minimum central pressure is 952 mb (28.12 inches).

----------------------
Key messages for Lorenzo can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml

WIND: Hurricane conditions are possible within the hurricane watch
area by early Wednesday, with tropical storm conditions possible by
late Tuesday.

RAINFALL: Lorenzo is expected to produce total rain accumulations
of 3 to 6 inches over much of the western Azores and 1 to 2 inches
over the central Azores Tuesday and Wednesday. This rainfall could
cause life-threatening flash flooding in the western Azores.

SURF: Swells generated by Lorenzo are spreading across much of the
North Atlantic basin. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult

Hurricane Lorenzo Discussion Number 31
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Sun Sep 29 2019

There haven't been a lot of changes with Lorenzo this evening, with
a small cloud-filled eye remaining visible and an enormous cloud
shield expanding in the northern semicircle. Satellite intensity
estimates support a somewhat lower intensity than the previous
advisory, so the initial wind speed is set to 95 kt. It should be
emphasized that even though the peak winds are down since yesterday,
the area of the hurricane-force winds has more than doubled during
that time.

Earlier aircraft data indicated that the large hurricane is
upwelling a significant amount of cooler waters under the storm, and
this is anticipated to cause Lorenzo to slowly weaken during the
next couple of days. While the SSTs drop off considerably after
late tomorrow, which would normally cause faster weakening, most of
the guidance is showing a favorable trough interaction at that time
with strong upper-level divergence. These effects are expected to
offset, and Lorenzo is likely to be a category 1 or 2 hurricane near
the Azores. Little change was made to the previous forecast, except
to raise the intensity a little higher near the Azores after more
heavily weighting the global models, which have been good performers
for this cyclone. The guidance is in very good agreement on Lorenzo
becoming an extratropical cyclone in about 72 hours, and that is
reflected in the latest forecast.

Lorenzo continues north-northeastward at 9 kt through a break in the
subtropical ridge. The forecast track confidence remains very high
through 48 hours as the hurricane is accelerated toward the
northeast ahead of a mid-latitude trough, and the new forecast is
essentially an update of the previous one. After that time,
however, there is a very large spread in the guidance caused by
whether Lorenzo is captured by the mid-latitude trough or if it
remains separate. There isn't much change in the newest guidance,
although it should be noted that the 12Z ECMWF solution is pretty
far east of its ensemble mean. The forecast track confidence is
extremely low beyond 72 hours, and the new NHC track was nudged
just a little to the left from the previous advisory, slightly east
of the various consensus aids.


Key Messages:

1. Lorenzo is a large and powerful hurricane, and its hurricane-
and tropical-storm-force wind fields are expected to expand further
during the next several days. Hurricane and Tropical Storm Watches
have been issued for the Azores, and these winds could start late
Tuesday or early Wednesday.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents.

Hurricane Lorenzo Discussion Number 30
NWS National Hurricane Center Miami FL AL132019
500 PM AST Sun Sep 29 2019

The cloud pattern has continued to degrade throughout the day with
cold cloud tops filling in the eye, with a gradual erosion of the
convection over the southwest quadrant. A recent AMSR2 pass confirms
that the eyewall is indeed open on the western side, and suggests
there may be another eyewall replacement cycle occurring. The NOAA
Hurricane Hunters are currently performing multiple experimental
flights inside and around Lorenzo, and are providing NHC with
valuable data. The wind data from the SFMR are indicating that the
hurricane-force winds extend outward farther than previously
thought, about 60-70 n mi from the center in all quadrants. The
aircraft also reported an adjusted minimum central pressure of 948
mb, a peak flight level wind of 99 kt, and an image capture from an
on-board radar that confirmed the break in the eyewall. The
available objective and subjective intensity estimates range from
102 kt to 114 kt. Based on a compromise of these data, the initial
intensity has been set at 100 kt, but this may be a little generous
given much lower dropsonde wind speeds measured by the aircraft.

Lorenzo continues north-northeastward at 9 kt through a weakness in
the subtropical ridge. A mid-latitude trough will approach Lorenzo
from the west in a couple of days. Increasing southwesterly flow
ahead of the trough will force the hurricane to turn northeastward
and accelerate beginning on Monday. The forecast track confidence
remains very high through 48 hours, and the new forecast is
essentially an update of the previous one. By 72 hours, the guidance
continues to diverge significantly, likely due to how they are
handling the interaction between Lorenzo and a larger extratropical
cyclone to its north late in the forecast period. The ECMWF/UKMET do
not have Lorenzo being absorbed into the larger low. Instead, they
track Lorenzo to the east-northeast toward Europe ahead of the
associated upper trough. The rest of the guidance has Lorenzo
absorbed into the low several hundred miles west of the British
Isles. The forecast track confidence remains low beyond 72 hours,
and was nudged just a little to the left from the previous advisory.

The aircraft near-surface dropsonde data suggests that Lorenzo is
moving over cooler waters of 24-25 degrees C, a few degrees cooler
than model guidance indicates, due to the upwelling of the waters
with lower oceanic heat content. The environmental conditions
for the next 48 hours are characterized by moderate southwesterly
shear, decent moisture, and strong upper-level divergence. Due to
the presence of the shear and cooler waters, gradual weakening is
anticipated for the next couple of days. By 72 hours, much stronger
shear and the interaction with the approaching mid-latitude trough
should cause the cyclone to weaken at a faster rate and begin to
transition to an extratropical cyclone. By 96 hours or so,
extratropical transition is expected to be complete. The official
intensity forecast was adjusted lower than the previous one
through 48 hours, and then is similar thereafter. This solution is
near the various multimodel consensus aids.


Key Messages:

1. Lorenzo is a large and powerful hurricane, and its hurricane-
and tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on
those islands Tuesday night and Wednesday, and residents there
should monitor the progress of the hurricane. Watches could be
issued for those islands later today or tonight.

2. Large swells generated by Lorenzo will continue to spread across
much of the north Atlantic basin during the next few days. These
swells will produce life-threatening surf and rip currents.

Hurricane Lorenzo Discussion Number 29
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Sun Sep 29 2019

Satellite and microwave imagery are indicating that Lorenzo is now
weakening. A recent microwave pass showed a broken eyewall as well
as dry air in the southwestern quadrant. Over the past hour, the eye
has begun to fill in. However, outflow remains excellent and cloud
tops remain very cold near the center of the hurricane. A blend of
the latest CI values from TAFB and SAB as well as a recent
subjective intensity estimate from UW-CIMSS suggest the initial
intensity is now 125 kt.

Lorenzo is moving north-northeastward at 9 kt through a weakness in
the subtropical ridge. A mid-latitude trough will approach Lorenzo
from the west in a couple of days. Increasing southwesterly flow
ahead of the trough will force the hurricane to turn northeastward
and accelerate beginning on Monday. The forecast track confidence is
very high through 72 hours, and the new forecast is in good
agreement with the tightly clustered consensus guidance and the
previous forecast. Beyond 72 hours, the guidance now diverges
significantly, likely due to how they are handling the interaction
between Lorenzo and a larger extratropical cyclone near Greenland
late in the forecast period. The majority of the guidance has
shifted to the west by several hundred miles over the past couple of
runs. However, there remains significant spread between the
operational UKMET/ECMWF which take what's left of Lorenzo toward the
British Isles, and the solutions that absorb the cyclone into the
larger system well over 1000 miles to the west. Based on the recent
shift in the models and the large spread, the official forecast was
only adjusted a little to the left and lies well to the right of the
consensus aids. Needless to say, the forecast track confidence
beyond 72 hours is low at the moment, and may need further
adjustments in the next couple of advisories.

Lorenzo reached its peak intensity last night, and the intensity
guidance is in good agreement that the hurricane will steadily
weaken over the next several days due to increasing southwesterly
shear, dry air entrainment, and progressively cooler SSTs. The NOAA
Hurricane Hunters are still scheduled to investigate Lorenzo later
today, and the data they collect should provide a better assessment
of the hurricane's intensity and structure. In a few days, Lorenzo
will interact with a frontal zone and begin transitioning to an
extratropical cyclone. This transition is expected to be complete by
96 hours. It is important to note that although Lorenzo is
forecast to weaken through the forecast period, the wind field is
expected to expand at the same time, with tropical-storm-force and
50 kt winds forecast to extend over 300 n mi/ 160 n mi respectively
from the center in 72 hours. The latest intensity forecast is
similar to the previous one, and it is near the HFIP corrected
consensus HCCA.

Earlier input from the Tropical Analysis and Forecast Branch here at
NHC indicates that the large wind field of Lorenzo and its expected
faster forward motion in a few days will likely lead to extreme
enhancement of the wave field and wave growth over the southeastern
portion of the circulation.

Key Messages:

1. Lorenzo is a large and powerful hurricane, and its hurricane-
and tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on
those islands Tuesday night and Wednesday, and residents there

issued for those islands later today or tonight.

2. Large swells generated by Lorenzo will continue to spread across

Hurricane Lorenzo Discussion Number 28
NWS National Hurricane Center Miami FL AL132019
500 AM AST Sun Sep 29 2019

The satellite appearance of Lorenzo is not quite as impressive as it
was several hours ago. Although the eye is still very distinct,
the cloud tops are not as cold in the eyewall and there are a few
dry slots evident beyond the inner core. The initial wind speed is
lowered just slightly to 135 kt, but based on the latest satellite
estimates this is probably generous. The NOAA Hurricane Hunters are
scheduled to investigate Lorenzo later today, and the data they
collect should provide a better assessment of the hurricane's
intensity and structure. Very intense hurricanes like Lorenzo are
usually not able to maintain their intensity for very long. Since
Lorenzo will be moving toward cooler waters and into an environment
of drier air and higher wind shear during the next several days,
steady weakening is forecast. Lorenzo is now expected to become
extratropical by day 4, when the cyclone will be over SSTs colder
than 20 C. The NHC intensity forecast is in good agreement with the
consensus models, IVCN, IVDR, and HCCA.

Lorenzo is still moving northward at 9 kt through a break in the
Atlantic subtropical ridge. A mid- to upper-level trough currently
over eastern Canada is expected to amplify when it reaches the
central Atlantic, which should cause Lorenzo to accelerate to the
northeast during the next few days. This motion should take the
core of Lorenzo near or just west of the Azores late Tuesday and
Wednesday. After that time, there are significant differences in
the models on whether or not Lorenzo interacts with an extratropical
low over the north Atlantic. The ECMWF and UKMET models show little
interaction with that low and show Lorenzo moving east-northeastward
in the westerlies toward northwestern France, Ireland, and the
United Kingdom. On the other hand, the GFS, HWRF, and HMON models
show Lorenzo rotating around the eastern side of the low and
remaining over the Atlantic. The spread in the models is incredibly
large, about 1300 n mi by day 5. Given the high uncertainty at this
time, only small changes were made to the NHC track forecast, and
this one favors the UKMET and ECMWF solutions. However, confidence
in the long-term track is very low and adjustments may be needed
later today.

The Tropical Analysis and Forecast Branch here at NHC provided
input that the large wind field of Lorenzo and its expected
faster forward motion in a few days will likely lead to extreme
enhancement of the wave field and wave growth over the southeastern
portion of the circulation.

Key Messages:

1. Lorenzo is a large and powerful hurricane, and its hurricane-
and tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on
those islands Tuesday night and Wednesday, and residents there

gusts. Lorenzo is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Although gradual weakening is forecast,
Lorenzo is expected to be a large and powerful hurricane as it
approaches the Azores.

Hurricane-force winds extend outward up to 50 miles (85 km) from the
center and tropical-storm-force winds extend outward up to 275 miles
(445 km).

The estimated minimum central pressure is 925 mb (27.32 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: Lorenzo is expected to produce total rain accumulations
of 3 to 6 inches over much of the western Azores and 1 to 2 inches
over the central Azores Tuesday and Wednesday. This rainfall could
cause life-threatening flash flooding in the western Azores.

SURF: Swells generated by Lorenzo are spreading across much of the
North Atlantic basin. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Hurricane Lorenzo Discussion Number 27
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Sat Sep 28 2019

Lorenzo has rapidly strengthened this evening. An eyewall
replacement cycle completed earlier today, with a recent SSMIS
microwave overpass showing that a new eyewall about 30 n mi in
diameter now completely encircles the eye. The cold cloud tops
surrounding the eye have expanded, with a solid ring of temperatures
measuring colder than minus 70 degrees Celsius. In addition, the
eye has cleared, with satellite derived cloud-top temperatures now
above 15 degrees Celsius. Throughout the evening, the objective and
subjective intensity estimates have climbed, with 0130 UTC special
classifications from TAFB and SAB as well as a recent UW-CIMSS ADT
estimate unanimously agreeing on a 140-kt initial intensity. This
makes Lorenzo an extremely dangerous category 5 hurricane.

The initial motion is now northward at 9 kt. Lorenzo will be
steered north through a break between two subtropical ridges through
tonight, with a turn to the north-northeast expected on Sunday.
After Sunday, Lorenzo will begin to get caught up in increasing
southwesterly flow ahead of an approaching mid-latitude trough. This
will cause the cyclone to accelerate northeastward through the end
of the forecast period. The official track forecast is essentially
an update of the previous one, and is near the middle of the
consensus aids.

Lorenzo will likely peak in intensity overnight as it remains in the
current favorable environment. Some fluctuations in intensity are
possible on Sunday mainly due to eyewall replacement cycles. By
Sunday night, Lorenzo will begin to feel the effects of some
southwesterly shear ahead of the approaching trough, while it also
moves over waters of lower oceanic heat content. These factors
should induce a steady weakening trend through 48 hours. After that
time, SSTs below 26 C should cause a faster weakening trend. By 72
hours, the cyclone will begin interacting with the approaching
trough and an associated cold front, which will begin a transition
to an extratropical low. This transition is forecast to complete by
120 hours, but it could happen a little sooner than that. The
official forecast was increased through the first 48 hours due to
the increase in initial intensity, and then blends to near the
previous official forecast by 72 hours.

With this latest advisory intensity, Lorenzo becomes the strongest
hurricane in history this far north and east in the Atlantic basin.


Key Messages:

1. Lorenzo is a large hurricane, and its hurricane- and
tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on
the islands Tuesday night and Wednesday, and residents there should
monitor the progress of the hurricane.

2. Large swells generated by Lorenzo will continue to spread across
much of the western and northern parts of the Atlantic basin during
the next few days. These swells will produce life-threatening surf
and rip currents.

Hurricane Lorenzo Special Discussion Number 26
NWS National Hurricane Center Miami FL AL132019
800 PM AST Sat Sep 28 2019

The satellite presentation of Lorenzo has improved throughout this
evening, and the ring of cloud tops surrounding the eye have
become wider and colder. This has resulted in both subjective and
objective satellite intensity estimates increasing to a 6.5 on the
Dvorak scale, indicative of a 125 kt hurricane. Based on this data,
a special advisory is being issued at this time to increase the
initial intensity, and the 12-hour and 24-hour forecast wind
speeds. No other changes were required to the previous track or
intensity forecast.

Key Messages:

1. Lorenzo is a large hurricane, and its hurricane- and
tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on

Hurricane Lorenzo Discussion Number 25
NWS National Hurricane Center Miami FL AL132019
500 PM AST Sat Sep 28 2019

A NOAA Hurricane Hunter aircraft conducting a research mission has
been invaluable in helping us to observe reintensification after
Lorenzo's eyewall replacement. The plane measured a peak 700-mb
flight-level wind of 126 kt and SFMR surface winds as high as 112
kt. In addition, the latest UW-CIMSS SATCON estimate is 114 kt.
These data support increasing the initial intensity to 115 kt, which
makes Lorenzo a category 4 hurricane again. The plane also reported
a circular eye 34 n mi wide and a central pressure around 950 mb.

Lorenzo is moving northward, or 355/9 kt, through a gap in the
subtropical ridge. The western Atlantic ridge is becoming stronger
than the eastern Atlantic ridge, and this should help to nudge
Lorenzo north-northeastward between 24-48 hours. After that
period, a deep-layer trough over the north Atlantic should turn
Lorenzo northeastward, with the hurricane's forward motion
accelerating as it becomes embedded in the mid-latitude westerlies.
The updated NHC track forecast has been placed near the HCCA model
and the other consensus aids, which keeps it very close to the
previous official forecast, at least through day 4. Some southward
adjustment of the track was made at day 5 based on the latest
global model guidance.

Fluctuations in Lorenzo's intensity are possible over the next day
or so. However, on the whole, moderate westerly shear and
decreasing oceanic heat content ahead of the hurricane are expected
to contribute to a very gradual weakening trend over the next 3
days. After day 3, Lorenzo is forecast to begin interacting with
an approaching cold front from the northwest, which would start
extratropical transition. The global models indicate that the
transition should be complete soon after 96 hours, so for the
moment the advisory continues to show tropical status on day 4.
Faster weakening is expected during and after extratropical
transition, and the updated NHC intensity forecast has been lowered
slightly from the previous forecast on days 4 and 5.

Key Messages:

1. Lorenzo is a large hurricane, and its hurricane- and
tropical-storm-force wind fields are expected to expand further
during the next several days. Regardless of Lorenzo's exact track
near the Azores, strong winds are becoming increasingly likely on
the islands Tuesday night and Wednesday, and residents there should
monitor the progress of the hurricane.

2. Large swells generated by Lorenzo will continue to spread across
much of the western and northern parts of the Atlantic basin during
the next few days. These swells will produce life-threatening surf
and rip currents.

Hurricane Lorenzo Advisory Number 25
NWS National Hurricane Center Miami FL AL132019
500 PM AST Sat Sep 28 2019

...NOAA HURRICANE HUNTER AIRCRAFT FINDS THAT LORENZO HAS
RESTRENGTHENED INTO A CATEGORY 4 HURRICANE...


SUMMARY OF 500 PM AST...2100 UTC...INFORMATION
----------------------------------------------
LOCATION...23.3N 45.0W
ABOUT 1470 MI...2365 KM SW OF THE AZORES
MAXIMUM SUSTAINED WINDS...130 MPH...215 KM/H
PRESENT MOVEMENT...N OR 355 DEGREES AT 10 MPH...17 KM/H
MINIMUM CENTRAL PRESSURE...950 MB...28.06 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.

Interests in the Azores should monitor the progress of Lorenzo.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the eye of Hurricane Lorenzo was located
near latitude 23.3 North, longitude 45.0 West. Lorenzo is moving
toward the north near 10 mph (17 km/h), and this motion is
expected to continue through tonight. A turn toward the
north-northeast is forecast on Sunday, followed by a faster motion
toward the northeast beginning Monday or Tuesday. On the forecast
track, the center of Lorenzo will be approaching the Azores on
Tuesday.

Data from a NOAA Hurricane Hunter aircraft indicate that maximum
sustained winds have increased to near 130 mph (215 km/h) with
higher gusts. Lorenzo is a category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Fluctuations in intensity are
possible during the next day or so. Lorenzo is expected to
gradually weaken through Tuesday, but it will remain a large and
potent hurricane while it approaches the Azores.

Lorenzo is a large hurricane. Hurricane-force winds extend outward
up to 50 miles (85 km) from the center, and tropical-storm-force
winds extend outward up to 275 miles (445 km).

The minimum central pressure based on data from the plane is 950 mb
(28.06 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and the Lesser Antilles and are
expected to spread westward to portions of the north coasts of the
Greater Antilles, the Bahamas, Bermuda, and the east coast of the
United States during the next few days. Swells are also expected
to build near the Azores on Sunday and Monday. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Hurricane Lorenzo Discussion Number 24
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Sat Sep 28 2019

Lorenzo appears to be in the final stages of an eyewall
replacement. 37-GHz GCOM imagery from overnight suggested that a
smaller inner eyewall was embedded within a larger eye, and the new
eyewall now extends 40-45 n mi from the center of circulation. An
eye has also reappeared in GOES-16 visible and infrared satellite
imagery during the past several hours. Based on Dvorak intensity
estimates of T5.5/102 kt from TAFB and SAB, and an ADT estimate of
T5.3/97 kt, Lorenzo's intensity is still estimated to be 100 kt.

Although the hurricane seems to be wobbling a bit, fixes indicate
that it has generally turned northward with an initial motion of
350/9 kt. The track forecast remains straightforward, with very
little spread among the models and their ensembles. Lorenzo is
expected to be nudged north-northeastward and then northeastward
starting in 36 hours by strong ridging building over the western
Atlantic. The northeastward motion is expected to increase on day
3 when Lorenzo is picked up by a strong deep-layer trough over the
north Atlantic, and that acceleration is forecast to continue
through day 5. The NHC track forecast lies near the consensus aids
and is very similar to the previous forecast.

A little bit of west-southwesterly shear continues over Lorenzo,
but it's not strong enough to disrupt the circulation
significantly. Only a very slow, gradual weakening is forecast
during the next 3 days, matching what is indicated by many of the
intensity models. Extratropical transition is expected to have
begun by day 4 while Lorenzo is moving near the Azores, but that
process is not expected to be complete until day 5. Although
Lorenzo's winds are forecast to decrease a bit during the
extratropical transition due to stronger shear and cold waters, the
cyclone is expected to maintain hurricane-force winds through the
end of the forecast period.

Lorenzo's wind field will remain large, and the hurricane-force
wind radii are expected to grow in size during the next couple of
days. In addition, large swells continue to radiate outward away
from the hurricane and will reach much of the western and northern
side of the Atlantic basin in a few days.

WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Lorenzo was
located near latitude 22.5 North, longitude 44.8 West. Lorenzo is
moving toward the north near 10 mph (17 km/h), and this general
motion is expected to continue through Sunday morning. A turn
toward the north-northeast is forecast on Sunday, followed by a
faster motion toward the northeast beginning Monday or Tuesday.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Lorenzo is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Only very gradual weakening is expected
during the next few days, and Lorenzo is forecast to remain a
strong hurricane when it turns toward northeastward towards the
Azores.

Lorenzo is a large hurricane. Hurricane-force winds extend outward
up to 50 miles (85 km) from the center, and tropical-storm-force
winds extend outward up to 275 miles (445 km).

The estimated minimum central pressure is 957 mb (28.26 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and the Lesser Antilles and are
expected to spread westward to portions of the north coasts of the
Greater Antilles, the Bahamas, Bermuda, and the east coast of the
United States during the next few days. Swells are also expected
to build near the Azores on Sunday and Monday. These swells are
likely to cause life-threatening surf and rip current conditions.

Hurricane Lorenzo Discussion Number 23
NWS National Hurricane Center Miami FL AL132019
500 AM AST Sat Sep 28 2019

Lorenzo's tilt has grown this morning. AMSR2 imagery at 0505 UTC
showed a 20 n mi displacement between the low- and mid-level centers
of the hurricane, a consequence of persistent westerly wind shear.
Satellite-based intensity estimates vary greatly, from 77 to 110 kt,
so the intensity is set to 100 kt as a compromise of all available
data. Despite the decrease in Lorenzo's maximum winds during the
past 24 hours, earlier ASCAT-C data showed that its hurricane-force
wind field has expanded, and now reaches up to 45 n mi to the
northeast of the center.

The lower initial intensity resulted in a slightly lower intensity
forecast through most of the period. The wind shear affecting the
cyclone is forecast to continue, and a slow decrease in Lorenzo's
peak winds is still expected during the next several days. The
official intensity forecast is very near the intensity consensus.
Despite the expected decrease in intensity, the hurricane is not
forecast to decrease in size, and in fact Lorenzo's hurricane-force
wind field could increase further by next week. Because of that,
users are urged to not focus on the exact intensity of Lorenzo since
the cyclone will likely remain a powerful storm well into next week.
By 120 h, all of the global models indicate that Lorenzo will become
post-tropical, and so does the NHC forecast.

The aforementioned microwave data was very helpful in identifying
Lorenzo's center location. The hurricane has continued to move left
of the forecast track, and the initial motion estimate is 330/9 kt.
Despite Lorenzo's recent tendency to move farther west than
anticipated, the hurricane is still forecast to turn northward soon.
After continuing northward and north-northeastward for a day or two,
Lorenzo should accelerate toward the northeast ahead of a deep
mid-latitude trough approaching from the west by mid-week. The NHC
track forecast has been shifted slightly left for the first 48 h to
account for Lorenzo's recent motion, but it is very similar to the
previous forecast at 72 h and beyond. The models are in excellent
agreement for the first 3 days of the forecast but the uncertainty
grows by the end of the period, primarily due to differences in the
forecast forward speed of the cyclone as it recurves and becomes
post-tropical.

BULLETIN
Hurricane Lorenzo Advisory Number 23
NWS National Hurricane Center Miami FL AL132019
500 AM AST Sat Sep 28 2019

...LARGE LORENZO STILL A MAJOR HURRICANE...


SUMMARY OF 500 AM AST...0900 UTC...INFORMATION
----------------------------------------------
LOCATION...21.4N 44.8W
ABOUT 1560 MI...2510 KM SW OF THE AZORES
MAXIMUM SUSTAINED WINDS...115 MPH...185 KM/H
PRESENT MOVEMENT...NNW OR 330 DEGREES AT 10 MPH...17 KM/H
MINIMUM CENTRAL PRESSURE...957 MB...28.26 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Hurricane Lorenzo was
located near latitude 21.4 North, longitude 44.8 West. Lorenzo is
moving toward the north-northwest near 10 mph (17 km/h). A turn
toward the north is anticipated today, followed by a turn toward
the north-northeast on Sunday.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Lorenzo is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Gradual weakening is expected during the
next few days, however, Lorenzo is expected to remain a powerful
hurricane through the weekend.

Lorenzo is a large hurricane and hurricane-force winds extend
outward up to 50 miles (85 km) from the center.
Tropical-storm-force winds extend outward up to 290 miles (465 km).

The estimated minimum central pressure is 957 mb (28.26 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and the Lesser Antilles. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.


NEXT ADVISORY

Hurricane Lorenzo Discussion Number 22
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Fri Sep 27 2019

Lorenzo's cloud pattern has continued to deteriorate this evening.
A series of SSMI and GMI microwave overpasses revealed inner core
erosion, particularly in the south portion. The images also showed
a significant south to north vertical tilt of the cyclone,
indicative of the moderate southwesterly shear undercutting the
impressive upper-tropospheric diffluent flow. A blend of all the
available subjective and objective satellite intensity estimates, as
well as an earlier SATCON analysis, yields an initial intensity of
105 kt for this advisory.

Lorenzo will remain over warm oceanic sea surface temperatures for
the next 3 days. Nonetheless, the stiff southwesterly shear should
inhibit strengthening, although there is a slight chance of
short-term fluctuations in intensity caused by eyewall replacement
cycles. Beyond the 72 hour period, Lorenzo is expected to encounter
stronger mid-latitude westerlies, move over cooler waters, and
undergo extratropical transition as it interacts with a baroclinic
zone moving over the central north Atlantic. The NHC forecast is an
update of the previous advisory and is based on a blend of the HFIP
Corrected Consensus and Florida State Superensemble intensity
models.

The aforementioned microwave images also indicate that Lorenzo has
been moving a little to the left of track, and the initial motion is
estimated to be north-northwestward, or 335/8 kt. The song remains
the same, no change in the track forecast philosophy. Lorenzo should
turn northward and then northeastward during the next few days as it
moves around the western periphery of a mid-tropospheric ridge
anchored over the eastern Atlantic. Around mid-period, Lorenzo is
forecast to accelerate toward the northeast, in the mid-latitude
westerly flow, in response to a deep-layer major shortwave trough
approaching from the north-central Atlantic. The track forecast has
been adjusted slightly to the left of the previous one and is close
to the various consensus aids.

The wind radii have been adjusted using 2308 UTC METOP-B
scatterometer data. The forecast wind radii, beyond the 48 hour
period, is based primarily on the RVCN global consensus.

MINIMUM CENTRAL PRESSURE...952 MB...28.12 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Lorenzo was
located near latitude 20.8 North, longitude 44.1 West. Lorenzo is
moving toward the north-northwest near 9 mph (15 km/h). A turn
toward the north is expected by Saturday night, followed by a turn
toward the north-northeast on Sunday.

Maximum sustained winds are now near 120 mph (195 km/h) with higher
gusts. Lorenzo is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Gradual weakening is expected during the
next few days. However, Lorenzo is expected to remain a powerful
hurricane through the weekend.

Recent satellite wind data indicate that Lorenzo is still a very
large tropical cyclone. Hurricane-force winds extend outward up to
35 miles (55 km) from the center and tropical-storm-force winds
extend outward up to 275 miles (445 km).

The estimated minimum central pressure is 952 mb (28.12 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and the Lesser Antilles. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.

Hurricane Lorenzo Discussion Number 21
NWS National Hurricane Center Miami FL AL132019
500 PM AST Fri Sep 27 2019

The satellite appearance of Lorenzo has degraded further since the
last advisory, with only a hint of an eye still apparent in visible
imagery and the cold cloud tops in the eyewall becoming very
asymmetric in infrared imagery. A recent SSMI/S overpass shows
that the southern portion of the eyewall has eroded, possibly due to
shear or dry air intrusion. The microwave imagery also suggests an
outer convective band is forming, but it is not yet well enough
defined to call it an outer eyewall. Satellite intensity estimates
have continued to decrease, and the initial intensity is lowered to
110 kt as a blend of the various estimates. The hurricane continues
to have excellent outflow in the northern semicircle.

The initial motion remains 330/12 kt. There is no change in the
track forecast philosophy or the forecast confidence, as Lorenzo
should turn northward and then northeastward during the next few
days as it moves around the western edge of a mid-level ridge
centered over the eastern Atlantic. Later in the forecast period,
the cyclone is expected to accelerate northeastward in the
mid-latitude westerlies ahead of a deep-layer trough approaching
from the west. The track guidance for this advisory, while it
remains tightly clustered in direction, is a little slower than the
previous guidance. Based on this, the new forecast track is just a
little slower than the previous forecast.

Lorenzo will be passing over sea surface temperatures of 27-28C for
the next 48-72 h. However, it will be in an environment of moderate
vertical shear due to an upper-level trough not far to the west.
The intensity guidance responds to this by showing gradual
weakening during this time, and the new intensity forecast follows
the trend of the guidance. There is a possibility of fluctuations
in intensity caused by eyewall replacement cycles superimposed on
this weakening trend. After 72 h, the hurricane should encounter
stronger mid-latitude westerlies, move over cooler sea surface
temperatures, and eventually merge with the above-mentioned
deep-layer trough. As this occurs, Lorenzo is forecast to undergo
extratropical transition, with this being complete by 120 h.
Current indications from the global models are that Lorenzo will
retain hurricane strength through the transition.

WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Hurricane Lorenzo was
located near latitude 20.3 North, longitude 43.6 West. Lorenzo is
moving toward the north-northwest near 12 mph (19 km/h), and this
general motion is forecast to continue tonight. A turn toward the
north is expected on Saturday, followed by a turn toward the
north-northeast on Sunday.

Maximum sustained winds are now near 125 mph (205 km/h) with higher
gusts. Lorenzo is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Gradual weakening is expected during the
next few days. However, Lorenzo is expected to remain a powerful
hurricane through the weekend.

A combination of satellite wind data and reports from a NOAA
Hurricane Hunter aircraft indicate that Lorenzo remains a large
hurricane. Hurricane-force winds extend outward up to 45 miles
(75 km) from the center and tropical-storm-force winds extend
outward up to 265 miles (425 km).

The estimated minimum central pressure is 948 mb (28.00 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and will affect portions of the
Lesser Antilles beginning tonight through Saturday. These swells

Hurricane Lorenzo Discussion Number 20
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Fri Sep 27 2019

The structure of Lorenzo in conventional satellite imagery has
decayed a little since the last advisory, with the eye becoming
less distinct and the eyewall convection becoming more asymmetric.
There is no current microwave imagery to show whether this
weakening might be due to the start of an eyewall replacement
cycle or not. The various subjective and objective satellite
intensity estimates have decreased a little, so the initial
intensity is reduced to 120 kt. The hurricane has excellent cirrus
outflow in all directions except to the southwest.

The initial motion is 330/12 kt. There is no change in the track
forecast philosophy or the forecast confidence, as Lorenzo should
turn northward and then northeastward during the next few days as it
moves around the western edge of a mid-level ridge centered over the
eastern Atlantic. By the end of the forecast period, Lorenzo is
expected to accelerate northeastward in the mid-latitude westerlies
ahead of a deep-layer trough approaching from the west. The new
forecast track is nudged a little to the left of the previous track
based mainly on the initial position, and it lies near the various
consensus models.

Lorenzo is currently passing over a tongue of slightly cooler sea
surface temperatures, and it is forecast to reach slightly warmer
water in 12-24 h. After that, it stays over sea surface
temperatures near 28C through about 72 h. During this time, the
intensity will be controlled mainly by internal eyewall replacement
cycles and some ups and downs in the vertical shear as the hurricane
interacts with a couple of upper-level troughs. The intensity
guidance shows a slow weakening trend during this time, and the NHC
intensity forecast follows this. However, it would not be
surprising to see some fluctuations in intensity occur. After 72 h,
the cyclone will become embedded in the mid-latitude westerlies and
move over much colder water. This, and the approach of the
aforementioned deep-layer trough, will lead to extratropical
transition that will be underway, but likely not complete, by 120 h.

WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Lorenzo was
located near latitude 19.4 North, longitude 42.9 West. Lorenzo is
moving toward the north-northwest near 14 mph (22 km/h), and this
general motion is forecast to continue today. A turn toward the
north is expected tonight or on Saturday, followed by a turn toward
the north-northeast on Sunday.

Maximum sustained winds are near 140 mph (220 km/h) with higher
gusts. Lorenzo is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in strength are possible
today, and slow weakening is forecast to begin by the weekend.

Lorenzo is a large hurricane. Hurricane-force winds extend outward
up to 45 miles (75 km) from the center, and tropical-storm-force
winds extend outward up to 265 miles (425 km).

The estimated minimum central pressure is 943 mb (27.85 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo are affecting portions of the
northeastern coast of South America and will affect portions of the
Lesser Antilles beginning later today through Saturday. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.

Hurricane Lorenzo Discussion Number 19
NWS National Hurricane Center Miami FL AL132019
500 AM AST Fri Sep 27 2019

Lorenzo has maintained its impressive structure in satellite imagery
this morning. The hurricane still has a fairly clear eye surrounded
by very cold cloud tops. A 0423 UTC AMSR2 overpass showed a small
break in the deepest convection in the southwest eyewall of the
hurricane, but given how cloud tops have cooled since then, I
suspect that did not last long. Satellite intensity estimates have
not changed substantially since the last advisory, so the initial
intensity remains 125 kt.

The hurricane is moving steadily north-northwestward at 12 kt. The
track guidance is in remarkably good agreement on Lorenzo's track
and confidence in the forecast is high. Lorenzo should turn
northward and then northeastward during the next few days as it
moves around the western edge of a mid-level ridge centered over the
eastern Atlantic. By the end of the forecast period, Lorenzo will
likely accelerate northeastward ahead of mid-latitude trough
approaching from the west. The official track forecast is basically
unchanged since the last advisory and now sits right in the middle
of the guidance envelope.

The NHC intensity forecast is also mostly unchanged since the last
advisory. Although SHIPS diagnostics suggest that moderate
southwesterly shear could soon affect the cyclone, not much change
in strength is anticipated for the next 24 hours since Lorenzo will
be moving over slightly warmer waters and an eyewall replacement
cycle does not seem imminent. Gradual weakening is then anticipated
through early next week due to a modest increase in shear and a
decrease in available ocean heat content. Short-term fluctuations in
intensity related to eyewall replacement cycles are also possible
during that time. The NHC forecast remains on the high side of the
guidance for the first 24 hours, and is close to HCCA after that.

Hurricane Lorenzo Discussion Number 18
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Thu Sep 26 2019

Lorenzo has intensified even more this evening, with a clear eye
characterized by warm temperatures of up to 17 degrees
Celsius. The eye is now completely surrounded by a ring of
convection with cold cloud tops less than minus 70 degrees Celsius.
The subjective Dvorak intensity estimates from both TAFB and SAB,
as well as the objective intensity estimate from UW-CIMSS ADT
unanimously support increasing the initial intensity to 125 kt.
Lorenzo is a very large hurricane, with tropical storm force winds
extending over 200 n mi from the center in the northern semicircle,
and a cirrus cloud canopy that spans greater than a 10 degree
latitude by 10 degree longitude area.

The initial motion is now north-northwest, or 330/12 kt. Model
guidance is in very good agreement throughout the 5 day period on
the future track of Lorenzo. The hurricane will move through a break
in the subtropical ridge currently to its northwest over the next
couple of days, gradually turning to the north then northeast as it
rounds the periphery of a ridge to its east. Late in the forecast
period, Lorenzo will begin to accelerate as it gets caught in
southwesterly flow ahead of an approaching mid-latitude trough. The
model guidance made a slight shift to the left since the previous
advisory, but since the same guidance shifted right earlier today, I
did not want to make much of a change to the track. The official
forecast track is very near the previous one, and is now on the
right side of the consensus guidance.

The environment around Lorenzo is expected to change little over
the next day or so. Both dynamical and statistical guidance are
suggesting that the hurricane is nearing peak intensity. Therefore
only fluctuations in strength due to eyewall replacement cycles are
expected through about Friday night. Over the weekend, some moderate
westerly shear ahead of the approaching mid-latitude trough could
begin to slowly weaken the cyclone. Late in the forecast period,
the combination of strong upper level southwesterly winds and
cooler sea surface temperatures should cause a faster weakening
trend. The official forecast is essentially an update of the
previous one, and a little higher than most of the guidance through
the first 48 hours.

DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Hurricane Lorenzo was
located near latitude 17.6 North, longitude 41.5 West. Lorenzo is
moving toward the north-northwest near 14 mph (22 km/h), and this
motion is expected to continue through Friday. A turn to the
north is expected on Saturday, followed by a turn to the northeast
on Sunday.

Maximum sustained winds are near 145 mph (230 km/h) with higher
gusts. Lorenzo is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in strength are possible
through Friday night. A slow weakening trend is expected over the
weekend.

Lorenzo is a large hurricane, with hurricane-force winds extending
outward up to 45 miles (75 km) from the center and
tropical-storm-force winds extending outward up to 255 miles (405
km).

The estimated minimum central pressure is 939 mb (27.73 inches).


HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Lorenzo will affect portions of the
northeastern coast of South America beginning tonight, and
will affect portions of the Windward Islands beginning on Friday.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Hurricane Lorenzo Discussion Number 17
NWS National Hurricane Center Miami FL AL132019
500 PM AST Thu Sep 26 2019

Lorenzo has continued to intensify this afternoon, as the 20 n mi
wide eye has become better defined and the cloud tops in the
eyewall have gotten colder. Various subjective and objective
satellite intensity estimates are now in the 115-125 kt range, so
the initial intensity is increased to a possibly conservative 120
kt. The hurricane has excellent outflow in all directions except
to the west, where it is starting to interact with an upper-level
trough.

The hurricane has turned toward the northwest since the last
advisory, with the 12-h average motion now 310/10 kt and the shorter
term motion is even more toward the north. Lorenzo is approaching a
break in the subtropical ridge caused by a series of mid-latitude
troughs to the northwest of the hurricane, and the track guidance
models remain in excellent agreement that Lorenzo should recurve
through the break during the forecast period. After 24-36 h, the
guidance has shifted a little more to the right, and this part of
the new track forecast has been nudged a little to the right.

Data from the SHIPS model suggest that Lorenzo will be in an area
of maximum potential intensities of 125-135 kt for the next 3-4
days. This suggests that the current intensification should end
soon as the actual intensity approaches or reaches those speeds.
Fluctuations in strength due to eyewall replacement cycles are
expected during the 12-24 h period. The global models suggest that
Lorenzo's interaction with the aforementioned upper-level trough
should increase during recurvature, which should cause increased
shear and a gradual weakening of the cyclone. As Lorenzo
subsequently moves northeastward in the mid-latitude westerlies,
increased shear and cooler sea surface temperatures should lead to
at least a continued slow weakening. The new intensity forecast
has only minor changes from the previous forecast.

While its exact ranking will be determined later, Lorenzo is one of
the largest and most powerful hurricanes of record for the central
tropical Atlantic, with the only comparable hurricane in recent

Hurricane Lorenzo Discussion Number 16
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Thu Sep 26 2019

A review of microwave satellite imagery from last night suggests
that Lorenzo underwent an eyewall replacement cycle, with the
outer eyewall becoming predominant around 06Z-09Z. Around that
time, the hurricane started to rapidly intensify, with the eye
becoming much better defined in conventional satellite imagery. Raw
Data-T numbers from both subjective and objective versions of the
Dvorak Technique suggest that the maximum winds have increased to
near 115 kt, which will be the initial intensity for this advisory.
The initial wind radii have been revised based on a recently
received scatterometer overpass.

The initial motion is 295/11. Lorenzo is approaching a developing
break in the subtropical ridge caused by a series of mid-latitude
troughs to the northwest of the hurricane, and the track guidance
models are in excellent agreement that Lorenzo should recurve
through the break during the forecast period. There are no
significant changes to the guidance since the last advisory, and
there are no significant changes to the forecast track either.

Data from the SHIPS model suggest that Lorenzo will be in an area
of maximum potential intensities of 125-135 kt for the next 3-4
days. This suggests that the rapid intensification should end in
the next 6-12 h as the actual intensity approaches those speeds.
Fluctuations in strength due to eyewall replacement cycles are
expected during the 12-36 h period. The global models suggest
that Lorenzo will subsequently interact with an upper-level trough
during recurvature, which should cause a period of increased shear
and some weakening of the cyclone around 48 h. By 120 h, the
hurricane should weaken due to movement over colder water and into
strong shear in the mid-latitude westerlies.

While its exact ranking will be determined later, Lorenzo is one of
the largest and most powerful hurricanes of record for the central
tropical Atlantic, with the only comparable hurricane in recent
times near there being Gabrielle of 1989.

Hurricane Lorenzo Special Discussion Number 15
NWS National Hurricane Center Miami FL AL132019
600 AM AST Thu Sep 26 2019

Shortly after the issuance of the 0900 UTC advisory, Lorenzo's eye
quickly and drastically became more apparent in conventional
satellite imagery. The slightly ragged but clearing eye of the
hurricane is surrounded by very cold cloud tops, and it has become
clear that Lorenzo is rapidly intensifying. A 0900 UTC TAFB Dvorak
classification of 6.0/6.0 (115 kt) was used as the primary basis for
increasing the intensity of Lorenzo. Because objective fixes from
just a few hours ago were much lower, the intensity of the hurricane
has been increased, perhaps conservatively, to 110 kt. Since this is
10 kt above the previous 12-h forecast, a special advisory is
required to update the intensity forecast.

Additional strengthening is possible later today. Earlier intensity
guidance indicated that Lorenzo's intensity should level off in a
day or so, though none of the guidance correctly anticipated the
rate at which the hurricane has strengthened this morning. Now that
the hurricane has a closed eyewall, fluctuations in intensity due to
eyewall replacement cycles are also possible, though this is not
explicitly reflected in the updated forecast. By the end of the
forecast period, the updated NHC forecast is relaxed to the original
forecast and shows some gradual weakening. Further adjustments,
especially at 72 h and beyond, may be required later this morning.

No changes were made to the track forecast, which is based on the
previous regular advisory.

Hurricane Lorenzo Discussion Number 14
NWS National Hurricane Center Miami FL AL132019
500 AM AST Thu Sep 26 2019

Lorenzo's satellite appearance continues to steadily improve. The
cyclone has a large central dense overcast, with outflow established
in all quadrants. The hurricane has at times shown signs of a
developing eye, however, it has been mostly obscured during the last
few hours by expanding cloud tops associated with central (and
likely eyewall) convection. Although the eye is not yet apparent in
geostationary imagery, a 0618 UTC SSMIS overpass showed that Lorenzo
has developed a well-defined mid-level eye. TAFB and SAB Dvorak
classifications both support an intensity of 90 kt but objective
estimates are lower. The intensity of Lorenzo is therefore held at
85 kt as a compromise of the higher subjective and lower objective
assessments, but this could be a little conservative.

The hurricane is still moving west-northwestward, but a turn toward
the northwest is expected later today. Lorenzo has reached a break
in the subtropical ridge to the north and should now begin to gain
latitude at a faster rate. By day 3, the global models show Lorenzo
moving northward along the western periphery of the ridge and by the
end of the period it will likely turn northeastward and accelerate
ahead of an approaching deep-layer trough. While the models still
differ on the details of the forecast, like how fast Lorenzo will be
moving once it turns northward, they all show this general
evolution. The NHC forecast is mostly an update of the previous
advisory and is just west of the center of the guidance envelope.

Lorenzo has several more days during which it could strengthen. The
primary limiting factor appears to be the size of Lorenzo, which is
considerable and is forecast to increase. This will likely only slow
down Lorenzo's strengthening, not prevent it. By 72 h, Lorenzo could
experience an increase in shear, and most of the guidance responds
by forecasting very slow weakening. The official intensity forecast
is generally close to HCCA and IVCN at all lead times and is not
very different from the previous forecast.

Hurricane Lorenzo Discussion Number 13
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Wed Sep 25 2019

A small eye has been intermittently appearing in infrared satellite
imagery over the past few hours, and a recent WINDSAT microwave
overpass showed that the inner-core of Lorenzo is trying to
consolidate. There is still some dry air wrapping in toward the
center of circulation as seen in an SSMIS overpass at 2020 UTC. This
could be the reason why the hurricane has not been able to develop a
well-defined eye as of yet. An ASCAT-B scatterometer pass this
evening showed a still expanding wind field associated with Lorenzo,
and the 50-kt winds now extend up to 90 n mi from the center in the
northern semicircle. A blend of the subjective intensity estimates
from TAFB and SAB support the initial intensity of 85 kt for this
advisory.

Based on the improving inner-core structure, large central dense
overcast, and an expanding cirrus shield around the hurricane, it is
believed that the dry air that has been entrained near the center
will mix out soon. This should allow for the eyewall to completely
develop and Lorenzo should reach major hurricane intensity within
the next 24 hours. Lorenzo will continue over warm waters and in a
light shear environment during the next couple of days, which should
allow for some additional strengthening. By 72 hours, increasing
shear due to west to southwest winds aloft ahead of an approaching
mid-latitude trough should begin to weaken the hurricane. The
official intensity forecast is very near the previous one, and is on
the high end of the guidance through 72 hours.

Lorenzo is moving west-northwest at 13 kt to the south of a
mid-level ridge. The model guidance is in very good agreement on a
break developing in the ridge between 45W-50W in the next couple of
days, which should result in a turn to the northwest. From day 3-5,
the cyclone is expected to turn north then northeast around the
periphery of the mid-level ridge to its east. The official forecast
was nudged just a little to the right of the previous one starting
at 36 h and is on the left side of tightly clustered consensus
guidance.

Hurricane Lorenzo Discussion Number 12
NWS National Hurricane Center Miami FL AL132019
500 PM AST Wed Sep 25 2019

Conventional satellite imagery indicates that Lorenzo continues to
become better organized, with the central dense overcast getting
larger while a large complex of outer bands continues in the
southeastern semicircle. In addition, a AMSR-2 overpass near 1530
UTC suggested there is at least a partial eyewall or convective ring
near the center. The initial intensity is increased to 80 kt in
best agreement with the CIMSS satellite consensus intensity
estimate. The hurricane still shows good cirrus outflow in all
directions, and it still appears some dry air is entraining into the
system in the northwestern quadrant.

The initial motion is now 285/16. There is no change to the track
forecast philosophy from the previous advisory. The subtropical
ridge to the north and northeast of Lorenzo should steer the
hurricane west-northwestward for the next day or so, followed by a
turn toward the northwest as a break develops in the ridge between
45W-50W. Lorenzo is subsequently forecast to turn northward into
the break by 96 h and recurve into the westerlies around 120 h.
Since the last advisory, the track guidance has shifted a little to
the right after 36 h. The new forecast track is similar to the
previous track, but after 36 h it now lies a little to the left of
the center of the guidance envelope.

Lorenzo should remain over warm water and in a light shear
environment during the next three days, with the only negative
factor for intensification being episodic intrusions of dry air.
The intensity guidance forecasts continued steady strengthening for
the next 36 h or so, but the the chances of rapid intensification
in the various statistical indices have gone down since the previous
advisory. The new intensity forecast will call for 36 more hours
of intensification, and it continues to lie near the upper edge of
the intensity guidance. The intensity forecast follows the general
trend of the guidance in showing little change in strength between
36-96 h, although fluctuations in intensity are likely due to
eyewall replacement cycles during this time. After that time,
Lorenzo is likely to encounter southwesterly shear, and thus some
weakening is forecast.

Hurricane Lorenzo Discussion Number 11
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Wed Sep 25 2019

Conventional satellite imagery indicates that Lorenzo continues to
become better organized, with a small central convective feature
surrounded by a large complex of outer bands in all quadrants
except the northwest, where some dry air may be entraining.
Satellite intensity estimates from TAFB, SAB, and the CIMMS
satellite consensus technique have increased to near 75 kt, and that
will be the initial intensity for this advisory. The hurricane
currently has good cirrus outflow in all directions.

The initial motion is 285/15. The subtropical ridge to the north
and northeast of Lorenzo should steer the hurricane west-
northwestward for the next day or so, followed by a turn toward the
northwest as a break develops in the ridge between 45W-50W. Lorenzo
is subsequently forecast to turn northward into the break by 96 h
and recurve into the westerlies around 120 h. While the guidance
agrees with this scenario, there is some spread on the longitude of
the recurvature between the easternmost GFS model and the
westernmost ECMWF model. The new forecast lies between these models
in best overall agreement with the HCCA corrected consensus
guidance.

Lorenzo should remain over warm water and in a light shear
environment during the next three days, with the only negative
factor for intensification being episodic intrusions of dry air.
The intensity guidance forecasts continued steady strengthening,
with rapid strengthening possible during the first 24-36 h. The
new intensity forecast is increased from the previous forecast, and
for the first 36-48 h it lies near the upper edge of the intensity
guidance. The intensity forecast shows little change in strength
between 36-72 h, although some fluctuations in intensity are likely
due to eyewall replacement cycles during this time. After 72 h,
Lorenzo is likely to encounter some southwesterly shear, and thus
some weakening is forecast.

Hurricane Lorenzo Discussion Number 10
NWS National Hurricane Center Miami FL AL132019
500 AM AST Wed Sep 25 2019

Deep convection has continued to increase in coverage and intensity
near the center of Lorenzo during the past several hours. There have
been no good microwave passes over the cyclone since yesterday,
however, a partial SSMIS pass showed hints that a mid-level eye is
forming. The initial intensity has been increased to 70 kt based on
a blend of the latest subjective Dvorak estimates from TAFB and SAB,
and objective estimates from the UW-CIMSS ADT and SATCON. Lorenzo is
the 5th hurricane of the Atlantic hurricane season.

The SHIPS and DTOPS rapid intensification probability models both
show that there is a greater than 50 percent chance that Lorenzo
will strengthen by 25 kt or more during the next 24 hours. The large
size of the cyclone appears to be the only obvious inhibiting factor
to rapid intensification since the environment is otherwise quite
favorable for continued strengthening. The NHC forecast now shows
Lorenzo becoming a major hurricane in 36 hours, faster than
previously anticipated. By 72 h and beyond, most of the guidance
keeps Lorenzo in a nearly steady state. In reality, most strong
hurricanes have some short-term fluctuations in intensity, but such
fluctuations are nearly impossible to forecast this far out in time.
Regardless of its exact intensity, confidence is high that Lorenzo
will be a large and powerful hurricane over the eastern and central
Atlantic through the rest of this week.

No changes of significance were made to the track forecast. Lorenzo
is still forecast to move west-northwestward for the next day or so,
before turning northwestward toward a weakness in the subtropical
ridge. A turn toward the north is anticipated by the end of the
forecast period. The models are still in fairly good agreement on
the track of the hurricane, and the NHC forecast is between the
consensus aids HCCA and TVCA.

Tropical Storm Lorenzo Discussion Number 9
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Tue Sep 24 2019

Over the past several hours, deep convection has increased in
coverage and intensity near Lorenzo's center, with cloud tops now as
cold as -85 degrees Celsius. Some modest northwesterly shear
impacted the cyclone starting early today and lasted through this
evening, but now Lorenzo seems to be overcoming the shear. The
initial intensity has been increased to 60 kt and this is a blend of
the latest subjective Dvorak estimates from TAFB and SAB. Recent
scatterometer passes show that the wind radii have continued to
expand, with tropical storm force winds now reaching up to 180 n mi
from the center.

Lorenzo is moving west-northwestward at 14 kt to the south of a
mid-level ridge. A break in the ridge is forecast to develop between
40-50W in a few days, which should cause the cyclone to turn to the
northwest. By late in the forecast period, Lorenzo will turn to the
north as it rounds the western periphery of the ridge. This forecast
track scenario is in very good agreement with the numerical models,
and little change was made from the previous official forecast.

The shear that has been occurring over Lorenzo is expected to
decrease through Wednesday, and based on the current convective
trend, strengthening appears likely over the next couple of days.
Dynamical and statistical models are in good agreement on bringing
Lorenzo to hurricane intensity by Wednesday morning, and then
continuing some gradual strengthening through 72 hours. After that
time, the dynamical model intensity forecasts diverge from the
statistical model forecasts. SHIPS and LGEM suggest that Lorenzo
will reach its peak intensity in about 3 or 4 days, and weakening is
possible by day 5. The dynamical models disagree with this scenario,
and the consensus of those models makes Lorenzo a major hurricane in
about 72 hours, with additional strengthening possible through the
end of the forecast period. The official forecast is more in line
with the dynamical guidance, although it is not as high as some of
those solutions late in the period. Due to the divergence in model
intensity forecasts beyond 72 hours, the confidence in the official
forecast at that time is not high.

Tropical Storm Lorenzo Discussion Number 8
NWS National Hurricane Center Miami FL AL132019
500 PM AST Tue Sep 24 2019

Based on recent microwave imagery and visible satellite loops, it
appears that there's been just enough westerly shear over Lorenzo
to disrupt the inner core and keep the storm from strengthening
through the day. The CDO is slightly offset from the low-level
center, and prominent convective banding is mostly within the
southeastern semicircle. Subjective intensity estimates remain
T3.5/55 kt from TAFB and SAB, and objective numbers have come up
slightly to around 60 kt. However, since the morning scatterometer
data was running about 10 kt lower than the satellite estimates,
and the overall structure has not changed appreciably, the initial
intensity will remain 55 kt.

A mid-level high centered west of Madeira and the Canary Islands
continues to drive Lorenzo quickly westward, or 285/15 kt. There
has been no change to the track forecast thinking. A break in the
ridge over the central Atlantic is expected to cause Lorenzo to
begin recurving in about 48 hours, with the system ultimately
moving northward by the end of the foreast period. The updated NHC
forecast has only been nudged westward, but this is mainly due to
the slightly faster initial forward motion. Otherwise, the spread
in the guidance is still bounded by the GFS on the right and the
ECMWF on the left, which is mirrored by those models' respective
ensemble members. The official forecast hedges toward the western
side of the guidance, roughly between the HCCA model and the other
consensus aids.

Global model guidance suggests that the westerly shear over Lorenzo
should abate during the next 24 hours, allowing another
intensification phase to begin. Whether or not rapid
intensification occurs is difficult to know at this point until it
becomes clearer if the cyclone can develop a well-defined inner
core. The intensity guidance has decreased further on this cycle,
but this is largely due to the hiatus in the strengthening trend
during the day. There's still plenty of time for more
strengthening to occur, so out of an abundance of caution, I did
not lower the forecast peak intensities that have been shown in the
previous few advisories. As such, the official forecast lies above
nearly all the guidance during the first 2-3 days, and then is
close to the HWRF and HCCA on days 4 and 5.

Tropical Storm Lorenzo Discussion Number 7
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Tue Sep 24 2019

Lorenzo's structure has not changed much during the morning. A
small central dense overcast continues over the center with
multiple curved bands within the circulation. A recent ASCAT pass
showed winds just over 45 kt to the north of the center, but given
sampling considerations, the initial intensity remains 55 kt, which
matches Dvorak classifications provided by TAFB and SAB.

Despite the brief interruption in the strengthening trend,
sufficiently warm waters, low shear, and an ambient moist air mass
should foster intensification during the next several days.
Because Lorenzo has not strengthened further since the previous
advisory, the persistence factor has caused the Rapid
Intensification (RI) Index (a 25-kt increase in 24 hours) to drop
from 53 percent to 23 percent. In addition, the overall guidance
envelope is showing slightly lower peak intensities in 3-4 days.
The NHC intensity forecast remains near the upper edge of the
guidance for much of the forecast period, lying closest to the HWRF
and the Florida State Superensemble. RI is still a possibility, but
as of yet we have not observed a low-level cyan ring in 37-GHz
microwave imagery, which is usually a harbinger of an RI episode.

The initial motion remains west-northwestward, or 285/14 kt.
Lorenzo is located to the south of a mid-level ridge which extends
from Morocco and Madeira Island westward to 40W. Ridging is
relatively non-existent west of 40W due to a mid-/upper-level low
over the central Atlantic and Tropical Storm Jerry over the western
Atlantic. With this pattern in place, Lorenzo is expected begin
recurving around the ridge axis over the central Atlantic on days
3-5. During that period, the track guidance envelope is bracketed
by the easternmost GFS and westernmost ECMWF models, which are
about 350 nm apart on day 5. This spread isn't too significant,
and the updated NHC track forecast is only shifted slightly
eastward from the previous one, very close to the two corrected
consensus aids.

Tropical Storm Lorenzo Discussion Number 6
NWS National Hurricane Center Miami FL AL132019
500 AM AST Tue Sep 24 2019

Satellite images indicate that the cloud pattern associated with
Lorenzo continues to become better organized, with many curved
bands and a newly formed central dense overcast. In fact, an
overnight AMSR2 microwave pass showed that Lorenzo already had a
very small central core. The initial wind speed is raised to 55 kt,
in accordance with the latest TAFB classification.

Conditions seem to be ripe for further intensification given that
the storm is over fairly warm waters, with humid mid-level air, and
weak/moderate shear. The SHIPS Rapid Intensification index is
giving a 53 percent chance of Lorenzo intensifying 25 kt during the
next 24 hours, which seems very reasonable since it now has a tight
inner core, and after noting the storm just strengthened 25 kt
during the previous 24 hours. Thus the intensity forecast is raised
from the last one, showing the initial period of very quick
strengthening, and is at the upper edge of the guidance. It is
worth noting that all of the global models show Lorenzo becoming a
fairly large and powerful hurricane within the next 5 days, and the
new wind radii forecast reflects this likelihood.

The storm is moving west-northwestward at about 14 kt. This general
course is expected for the next couple of days while Lorenzo moves
beneath the eastern Atlantic subtropical ridge. A break in the
ridge should occur in a few days over the central Atlantic, causing
the tropical cyclone to turn northwestward and north-northwestward
over the weekend. The new forecast is shifted slightly northward
in the short term, but is close to the previous NHC prediction
thereafter, closest to the corrected-consensus aids.

Tropical Storm Lorenzo Discussion Number 5
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Mon Sep 23 2019

Infrared satellite imagery and microwave data indicate that
convection and banding has been on the increase this evening very
near the the center of Lorenzo, while the existing bands that
extend well away from the center have been growing in size.
This improving organization supports raising the initial intensity
to 45 kt, and this is in agreement with the latest subjective Dvorak
estimates from both TAFB and SAB. A recent ASCAT-C overpass
sampled tropical-storm-force winds that now extend up to 80 n
mi in the northern semicircle and suggested that the initial wind
speed could be a little conservative.

Lorenzo will be in an environment favorable for intensification for
the next several days. And, given the recent increase in convection
near the storm's center, there is now greater confidence that
Lorenzo could become a hurricane by late tomorrow. If the near-term
forecast trend verifies, then it will raise confidence that
Lorenzo may become a major hurricane in the medium range. Only at
the very end of the forecast period does it appear that the system
will begin to encounter increasing shear and some drier air, which
should limit any further strengthening. The official NHC wind speed
prediction shows intensification a little faster than the last
forecast through the first couple of days, but is near the previous
advisory thereafter. This forecast is very close to the HFIP
corrected-consensus HCCA.

Lorenzo is moving westward at 13 kt. A strong mid-level ridge to
the north of the cyclone will steer it generally westward to
west-northwestward over the next few days. Late in the forecast
period, a break in the ridge is forecast to develop between 40-45W,
which should cause Lorenzo to turn to the northwest. The official
NHC forecast is very close to the previous one, and near the
tightly clustered consensus aids.

Tropical Storm Lorenzo Discussion Number 4
NWS National Hurricane Center Miami FL AL132019
500 PM AST Mon Sep 23 2019

Lorenzo is steadily getting better organized. Visible imagery before
sunset showed that the tropical storm has developed extensive
banding that wraps about 3/4 of the way around the circulation. An
1836 SSMIS overpass also shows this banding, but indicated that the
tropical storm has not developed a tight inner core. Satellite
intensity estimates range from 35 to 47 kt, and the intensity of the
system has been increased to 40 kt.

All indications are that Lorenzo is in a favorable environment for
strengthening, and all of the guidance continues to forecast that it
will become a hurricane during the next few days, perhaps as soon as
tomorrow. In fact, the SHIPS Rapid Intensification Index shows a
45 percent chance of a 25 kt or greater increase in Lorenzo's winds
during the next 24 hours. Since the tropical storm doesn't have a
tight inner-core yet, the NHC forecast isn't quite as bullish, but
still shows steady strengthening, and Lorenzo could become a major
hurricane later this week.

The tropical storm is moving steadily westward with an initial
motion of 275/14. The new NHC track forecast is essentially just an
update of the previous one, and no substantial changes were made.
Lorenzo will likely move generally westward to west-northwestward at
a similar forward speed for the next few days, before turning
northwestward over the weekend. The global models are in very good
agreement on this scenario, but do differ on how soon Lorenzo will
turn northwestward. The NHC forecast is based primarily on HCCA, and
is on the left side of the guidance envelope. This is also closer to
the ECMWF and UKMET forecasts which delay the start of Lorenzo's
recurvature a little more than the GFS and its derived models.

Tropical Storm Lorenzo Discussion Number 3
NWS National Hurricane Center Miami FL AL132019
1100 AM AST Mon Sep 23 2019

Yet another tropical storm has formed over the Atlantic, this one
over the far eastern portion of the basin. The system has been
designated as Tropical Storm Lorenzo based on satellite intensity
estimates from TAFB, SAB, and UW-CIMSS, all of which support
tropical-storm strength. The initial intensity is set at 35 kt, but
its possible this is somewhat conservative since the TAFB
classification was a little higher.

Recent GMI microwave imagery and ASCAT-C data showed that the
low-level center of Lorenzo is on the north side of most of its deep
convection. While this disorganized structure may limit how quickly
Lorenzo can strengthen in the short-term, the tropical storm is
located within a generally favorable environment for
intensification. All of the intensity guidance shows Lorenzo
becoming a hurricane, but the timing varies from model to model. The
official forecast follows the HFIP Corrected Consensus, and shows
Lorenzo reaching hurricane status within 48 h. Continued
strengthening is forecast thereafter. No noteworthy changes were
made to the NHC intensity forecast.

The ASCAT and microwave data were very helpful in determining the
location of Lorenzo's center and its forward speed. The cyclone
has accelerated and the initial motion estimate is now 275/15 kt.
Very little adjustment was made to the NHC track forecast. Lorenzo
is still forecast to be steered generally westward to
west-northwestward to the south of a deep-layer ridge centered over
the eastern Atlantic. The cyclone will pass well south and southwest
of the Cabo Verde Islands through tonight. A turn toward the
northwest is forecast in about 4 days as Lorenzo reaches a break in
the ridge. Just like the intensity forecast, the track forecast is
based heavily on HCCA.

Tropical Depression Thirteen Discussion Number 2
NWS National Hurricane Center Miami FL AL132019
500 AM AST Mon Sep 23 2019

Infrared and passive microwave satellite imagery indicate that the
depression is gradually getting better organized, with upper-level
outflow improving in all quadrants. However, the low-level and
mid-level circulations do not appear to be vertically aligned quite
yet, with the mid-level center displaced a little to the west of the
low-level center. As a result, the intensity has been maintained at
30 kt for this advisory.

The initial motion is 270/13 kt. A strong deep-layer ridge to the
north of the cyclone is expected to steer the system generally
westward to west-northwestward for the next 72 hours or so,
resulting in the center passing well to the south and southwest of
the Cabo Verde Islands today and tonight. On days 4 and 5, a motion
toward the northwest is expected as the cyclone begins to move into
a weakness in the ridge. The new track guidance remains tightly
clustered about the previous forecast track, so no significant
changes were required.

The cyclone is forecast to remain in light vertical shear conditions
throughout the 5-day period. That favorable upper-level flow regime
will combine with SSTs near 29 deg C and a moist mid-level
environment to allow the cyclone to steadily strengthen into a
hurricane by Tuesday and be near major hurricane strength by day 4.
The new NHC intensity forecast is just an update of the previous
advisory and closely follows the HCCA and IVCN consensus models.

Tropical Depression Thirteen Discussion Number 1
NWS National Hurricane Center Miami FL AL132019
1100 PM AST Sun Sep 22 2019

Satellite imagery and partial scatterometer overpasses indicate
that the tropical wave in the eastern tropical Atlantic has
developed enough circulation and organized convection to be
designated a tropical depression. The convection is currently
organized into a large band over the western semicircle, with an
additional smaller band to the southeast. The initial intensity is
set at 30 kt in best agreement with a satellite intensity estimate
from TAFB.

The initial motion is 270/14. A strong deep-layer ridge to the
north of the depression should steer it generally westward to
west-northwestward for the next 3-4 days, with the center passing
well to the south and southwest of the Cabo Verde Islands. Near
the end of the forecast period, the cyclone is expected to turn
northwestward as it approaches a weakness in the ridge. The track
guidance is tightly clustered, and the forecast track is in best
agreement with the HCCA corrected consensus model.

The cyclone is forecast to be in a light to moderate easterly shear
environment over warm sea surface temperatures for the next 3-4
days, and there are no obvious negative factors to prevent
strengthening. The intensity forecast thus calls for steady
intensification through 96 h, with the intensity forecast lying near
the upper edge of the guidance from 48-96 h. Some southwesterly
shear may develop near 120 h, so the forecast show little change in
strength from 96-120 h.
