Tropical Depression Hanna Discussion Number 16
NWS National Hurricane Center Miami FL AL082020
400 PM CDT Sun Jul 26 2020

Surface observations along with radar and satellite imagery show
that Hanna continues to weaken as it moves farther inland. There
have been no recent observations of sustained tropical-storm-force
winds, and Doppler velocities have continued to decrease. Based on
these trends, the initial wind speed has been reduced to 30 kt.
Hanna should continue to spin down while it moves over the high
terrain of northeastern Mexico. The system is forecast to become
a remnant low in 12-18 hours, and should dissipate over the
mountains of Mexico by late Monday, if not sooner.

Hanna is moving west-southwestward or 245/8 kt. The cyclone should
continue on this general heading and speed until dissipation
occurs. The updated NHC track forecast is again similar to the
previous advisory and is close to the dynamical model consensus.

This is the last NHC advisory on Hanna. Future information on this
system can be found in Public Advisories issued by the Weather
Prediction Center beginning at 10 PM CDT, under AWIPS header
TCPAT3, WMO header WTNT33 KWNH, and on the web at
http://www.wpc.ncep.noaa.gov.

Key Messages

1. Heavy rainfall from Hanna has already produced numerous reports
of flash flooding across south Texas. Additional heavy rainfall
will continue to result in life-threatening flash flooding over
south Texas and northern Mexico, and isolated minor river flooding
in south Texas.

Tropical Storm Hanna Discussion Number 15
NWS National Hurricane Center Miami FL AL082020
1000 AM CDT Sun Jul 26 2020

Surface observations and WSR-88D radar data from Brownsville, Texas,
indicate that Hanna continues to weaken as it moves farther
inland. The radar shows a couple of fairly well-defined bands of
convection over the eastern semicircle and tropical-storm-force
wind gusts have been reported at observing sites along the
U.S./Mexico border within the past couple of hours. The initial
intensity has been reduced to 40 kt, and is based primarily on
recent observations and Doppler radar velocities. Hanna should
continue to weaken quickly during the next 12-24 hours as it moves
inland over Mexico. Hanna is forecast to become a tropical
depression later today and dissipate over the mountainous terrain
of Mexico by Monday night.

Hanna is moving west-southwestward or 250/8 kt. The system is
forecast to continue moving west-southwestward around the southern
portion of a mid-level ridge over the central United States. The
new NHC track forecast is similar to the previous advisory and lies
near the various consensus aids.


Key Messages

1. Tropical storm conditions are expected to persist into this
afternoon near and to the east of the center of Hanna.

2. Heavy rainfall from Hanna has already produced numerous reports
of flash flooding across south Texas. Additional heavy rainfall
will continue to cause life-threatening flash flooding over south
Texas and northern Mexico, and isolated minor to moderate river
flooding in south Texas.

3. Storm surge along the Texas coast should continue to diminish
today.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Barra el Mezquital Mexico to Baffin Bay Texas

Interests in northeastern Mexico should monitor the progress of
Hanna.

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 700 AM CDT (1200 UTC), the center of Tropical Storm Hanna was
located near latitude 26.2 North, longitude 99.1 West. Hanna is
moving toward the west-southwest near 9 mph (15 km/h) and this
motion is expected to continue through Monday. On the forecast
track, the center of Hanna should continue to move farther inland
over northeastern Mexico through tonight.

Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Rapid weakening is expected as the center of Hanna moves
farther inland, and the cyclone is expected to weaken to a tropical
depression later today and dissipate Monday or Monday night.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
mainly over water to the east of the center. A wind gust of 49 mph
(80 km/h) was reported within the past couple of hours at Port
Isabel-Cameron County Airport.

The estimated minimum central pressure is 992 mb (29.29 inches).


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

STORM SURGE: Water levels along the Texas coast will gradually
subside through this morning. Consult products issued by your
local National Weather Service forecast office for additional
information.

WIND: Tropical storm conditions will continue near the center of
Hanna for the next several hours, and along the Texas and
northeastern Mexican coast in the warning area for a few more hours.

RAINFALL: Hanna is expected to produce total rain accumulations of 6
to 12 inches, with isolated maximum amounts of 18 inches through
Monday in south Texas and into the Mexican states of Coahuila, Nuevo
Leon, and northern Tamaulipas. This rain will produce
life-threatening flash flooding, rapid rises on small streams, and
isolated minor to moderate river flooding.

Hanna is also expected to produce 2 to 4 inches of rain along the
upper Texas and Louisiana coasts.

SURF: Swells generated by Hanna will continue to affect much
of the Texas and Louisiana coasts for another day or so. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible today into this evening
across parts of south Texas.

Tropical Storm Hanna Discussion Number 14
NWS National Hurricane Center Miami FL AL082020
400 AM CDT Sun Jul 26 2020

Hanna continues to weaken as the center crosses the Rio Grande
River from Texas into northeastern Mexico. Satellite imagery shows
some warming of the cloud tops near the center, and WSR-88D radar
data shows that only about a third of the previous eyewall is still
present to the southeast of the center. The storm is generating a
vigorous outer convective band over the eastern semicircle. The
initial intensity is reduced to 50 kt based mainly on Doppler radar
winds of 50-65 kt at about 9000 ft to the northeast of the center,
and it is possible that this is generous.

The initial motion remains west-southwestward or 250/8 kt. The
mid-level ridge over the central United States should continue to
steer Hanna west-southwestward until dissipation, and the new NHC
forecast track is little changed from the previous forecast.

Hanna should rapidly weaken as it moves over northeastern Mexico,
with the system expected to weaken to a depression in 12-18 h, if
not sooner. The system is expected to dissipate completely over the
rugged terrain of Mexico between 36-48 h.

The radar signature of the storm has weakened to the point where
there will be no more hourly position updates between advisories.

Key Messages

1. Tropical storm conditions are expected to persist for several
more hours near the center of Hanna, and for a few more hours in
the warning area along the coast of Texas and northeastern Mexico.

2. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains will result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

3. Storm surge along the Texas coast should diminish today.

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

The Hurricane Warning has been changed to a Tropical Storm Warning
along the Texas coast from Port Mansfield to Baffin Bay.

The Storm Surge Warning has been discontinued along the Texas coast
from Port Aransas to Port O'Connor.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Port Mansfield to Port Aransas

A Tropical Storm Warning is in effect for...
* Barra el Mezquital Mexico to Port O'Connor Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 24 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Tropical Storm Warning means that tropical storm conditions are
occurring within the warning areas.

Interests elsewhere along the Texas coast should monitor the
progress of Hanna. Interests in northeastern Mexico should also
monitor the progress of this tropical storm.

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 100 AM CDT (0600 UTC), the center of Tropical Storm Hanna was
located near latitude 26.5 North, longitude 98.5 West. Hanna is
moving toward the west-southwest near 9 mph (15 km/h) and this
motion is expected to continue through Sunday. On the forecast
track, the center of Hanna should continue to move farther inland
over southern Texas this morning and move into northeastern Mexico
later today.

Maximum sustained winds have decreased to near 70 mph (115 km/h)
with higher gusts. Rapid weakening is expected today as Hanna moves
farther inland.

Tropical-storm-force winds extend outward up to 105 miles (165 km)
from the center. A Texas Mesonet Station northeast of Edcouch,
Texas, recently reported a sustained wind of 48 mph (77 km/h) and a
wind gust of 68 mph (109 km/h).

The estimated minimum central pressure is 983 mb (29.03 inches).


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

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Port Aransas including Baffin Bay, Corpus Christi
Bay...4-6 ft

Port Mansfield to Baffin Bay...2-4 ft

Port Aransas to Port O'Connor including Aransas Bay...2-4 ft

Mouth of the Rio Grande to Port Mansfield...1-3 ft

North of Port O'Connor to High Island including Galveston Bay...1-2
ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Tropical storm conditions are occuring in portions of the
tropical storm warning area and will spread farther inland
overnight and Sunday.

RAINFALL: Hanna is expected to produce total rain accumulations of
6 to 12 inches, with isolated maximum amounts of 18 inches through
Monday in south Texas and into the Mexican states of Coahuila, Nuevo
Leon, and northern Tamaulipas. This rain will produce
life-threatening flash flooding, rapid rises on small streams, and
isolated minor to moderate river flooding.

Hanna is also expected to produce 2 to 4 inches of rain along the
upper Texas and Louisiana coasts.

SURF: Swells generated by Hanna will continue to affect much
of the Texas and Louisiana coasts for another day or so. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible overnight over parts of
the lower to middle Texas coastal plain.

CHANGES WITH THIS ADVISORY:

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Port Mansfield to Sargent Texas

A Hurricane Warning is in effect for...
* Port Mansfield to Port Aransas Texas

A Tropical Storm Warning is in effect for...
* Barra el Mezquital Mexico to Port Mansfield Texas
* Port Aransas to Port O'Connor Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 24 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Hurricane Warning means that hurricane conditions are occurring
within the warning area. Preparations to protect life and property
should have already been completed.

A Tropical Storm Warning means that tropical storm conditions are
occurring within the warning areas.

Interests elsewhere along the Texas and Louisiana coasts should
monitor the progress of Hanna. Interests in northeastern Mexico
should also monitor the progress of this hurricane.

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 700 PM CDT (0000 UTC), the eye of Hurricane Hanna was located
near latitude 26.7 North, longitude 97.5 West. Hanna is moving
toward the west-southwest near 8 mph (13 km/h) and this motion is
expected to continue through Sunday. On the forecast track, the
center of Hanna should continue to move farther inland over southern
Texas tonight and move into northeastern Mexico on Sunday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Rapid weakening is expected as Hanna moves farther inland.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).

The estimated minimum central pressure based on surface
observations is 975 mb (28.79 inches).


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

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Port Aransas including Corpus Christi Bay...4-6 ft

Port Mansfield to Baffin Bay...2-4 ft

North of Port Aransas to Sargent including Copano Bay , Aransas
Bay, San Antonio Bay, and Matagorda Bay...2-4 ft

Mouth of the Rio Grande to Port Mansfield...1-3 ft

North of Sargent to High Island including Galveston Bay...1-2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions will continue in portions of the
hurricane warning area through this evening. Tropical storm
conditions are occuring in portions of the tropical storm warning
area and will spread farther inland tonight and Sunday.

RAINFALL: Hanna is expected to produce total rain accumulations of
6 to 12 inches, with isolated maximum amounts of 18 inches through
Monday in south Texas and into the Mexican states of Coahuila,
Nuevo Leon, and northern Tamaulipas. This rain will produce
life-threatening flash flooding, rapid rises on small streams, and
isolated minor to moderate river flooding.

Hanna is also expected to produce 3 to 5 inches of rain along the
upper Texas and Louisiana coasts.

SURF: Swells generated by Hanna will continue to affect much
of the Texas and Louisiana coasts for another day or so. These
swells are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible this evening and overnight
over parts of the lower to middle Texas coastal plain.

Hurricane Hanna Discussion Number 12
NWS National Hurricane Center Miami FL AL082020
400 PM CDT Sat Jul 25 2020

NOAA Doppler weather radar data from Brownsville and Corpus Christi,
Texas, along with reconnaissance data from the Air Force Hurricane
Hunters indicate that Hanna has continued to strengthen this
afternoon. A 30-nmi-wide eye remains distinct in the radar data, and
dropsonde and 700-mb flight-level-level height data from the
aircraft indicate that the central pressure has decreased to 973 mb.
The aircraft measured a peak 700-mb flight-level wind speed of 86 kt
on its last outbound leg, which equates to about 77 kt at the
surface. Coincident with the flight-level wind data were SFMR
surface wind speeds of 80 kt. In addition, Doppler velocity values
have been averaging close to 100 kt between 5000-6000 ft in the
northern and northeastern eyewall, which converts to 80-kt surface
wind speed estimates. Based on these data, the initial intensity has
been increased to 80 kt. No further strengthening is anticipated
before the center of Hanna's eye makes landfall along the south
Texas coast in a few hours.

Doppler radar and aircraft reconnaissance fixes indicate that Hanna
has finally made the much anticipated turn toward the
west-southwest, now showing an initial motion of 255/07 kt. A
west-southwestward motion is expected to continue for the next 48
hours, which will take Hanna well inland over south Texas, followed
by eventual dissipation in about 48 h over over the mountains of
northeastern Mexico. The new NHC track forecast remains unchanged
from the previous advisory, and lies near the center of the tightly
packed consensus models.


Key Messages

1. Life-threatening storm surge will continue along portions of the
Texas coast from Port Mansfield to Sargent, where a Storm Surge
Warning is in effect. Residents in these locations should follow
advice given by local emergency officials.

2. Hurricane conditions will continue within the Hurricane Warning
area along the Texas coast through this evening. Strong winds will
also spread inland across portions of South Texas where Tropical
Storm and Hurricane Warnings are in effect.

3. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains will result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

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

The Hurricane Warning has been replaced by a Tropical Storm Warning
north of Port Aransas, Texas.

The Tropical Storm Warning has been discontinued north of Port
O'Connor, Texas.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Port Mansfield to Sargent Texas

A Hurricane Warning is in effect for...
* Port Mansfield to Port Aransas Texas

A Tropical Storm Warning is in effect for...
* Barra el Mezquital Mexico to Port Mansfield Texas
* Port Aransas to Port O'Connor Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 24 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.

officials.

A Hurricane Warning means that hurricane conditions are occurring
within the warning area. Preparations to protect life and property
should have already been completed.

A Tropical Storm Warning means that tropical storm conditions are
occurring within the warning areas.

Interests elsewhere along the Texas and Louisiana coasts should
monitor the progress of Hanna. Interests in northeastern Mexico
should also monitor the progress of this hurricane.

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 400 PM CDT (2100 UTC), the center of Hurricane Hanna was located
near latitude 26.8 North, longitude 97.2 West. Hanna is moving
toward the west-southwest near 8 mph (13 km/h) and this motion is
expected to continue through Sunday. On the forecast track, the
center of Hanna should make landfall along the Texas coast within
the hurricane warning area later this afternoon or early this
evening. After landfall, the center of Hanna will move inland over
south Texas tonight and move into northeastern Mexico on Sunday.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Some slight strengthening is still possible before Hanna
makes landfall in a few hours. Rapid weakening is expected after
Hanna moves inland.

Hurricane-force winds extend outward up to 30 miles (45 km) from the
center and tropical-storm-force winds extend outward up to 90 miles
(150 km). A TCOON observation station at Laguna Madre, Texas,
recently reported a sustained wind of 64 mph (104 km/h) and a gust
to 76 mph (122 km/h).

The estimated minimum central pressure is 973 mb (28.74 inches).


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

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Port Aransas including Corpus Christi Bay...4-6 ft

Port Mansfield to Baffin Bay...2-4 ft

North of Port Aransas to Sargent including Copano Bay , Aransas
Bay, San Antonio Bay, and Matagorda Bay...2-4 ft

Mouth of the Rio Grande to Port Mansfield...1-3 ft

North of Sargent to High Island including Galveston Bay...1-2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions will continue in portions of the
warning area through this evening. Tropical storm conditions are
occuring in portions of the tropical storm warning area and will
spread inland through this evening.

RAINFALL: Hanna is expected to produce total rain accumulations of
6 to 12 inches, with isolated maximum amounts of 18 inches through
Monday in south Texas and into the Mexican states of Coahuila,
Nuevo Leon, and northern Tamaulipas. This rain will produce
life-threatening flash flooding, rapid rises on small streams, and
isolated minor to moderate river flooding.

Hanna is also expected to produce 3 to 5 inches of rain along the
upper Texas and Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next couple of
days. These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible this afternoon and
overnight over parts of the lower to middle Texas coastal plain.

DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of the eye of Hurricane Hanna
was located by NOAA Doppler weather radars and buoy data near
latitude 27.0 North, longitude 96.7 West. Hanna is moving toward the
west near 8 mph (13 km/h). A gradual turn toward the west-southwest
is expected by late afternoon and tonight, and that motion should
continue through Sunday. On the forecast track, the center of Hanna
should make landfall along the Texas coast within the hurricane
warning area by late afternoon or early this evening.

Data from Doppler weather radars indicate that maximum sustained
winds are near 80 mph (130 km/h) with higher gusts. Some slight
strengthening is still possible before Hanna makes landfall later
today. Rapid weakening is expected after Hanna moves inland.

Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km). A TCOON observation station at Laguna Madre, Texas,
recently reported a sustained wind of 54 mph (91 km/h) and a gust to
70 mph (113 km/h).

Reports from NOAA buoy 42020 located near the center of Hanna's eye
indicate that the minimum central pressure is 977 mb (28.85 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and

WIND: Hurricane conditions are expected in the warning area
this afternoon. Tropical storm conditions are occuring in
portions of the warning area and will spread inland through the
afternoon and evening.

RAINFALL: Hanna is expected to produce 6 to 12 inches of rain with
isolated maximum totals of 18 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect

Hurricane Hanna Discussion Number 11
NWS National Hurricane Center Miami FL AL082020
1000 AM CDT Sat Jul 25 2020

NOAA Doppler radar data from Corpus Christi and Brownsville, Texas,
along with reconnaissance data from the NOAA Hurricane Hunters
indicate that Hanna has continued to strengthen this morning. A
well-defined but fairly large 30-35-nmi-wide eye has formed and
recent dropsonde data from the eye indicate that the central
pressure has dropped to 978 mb. The aircraft measured a peak 700-mb
flight-level wind speed of 77 kt, which equates to about 69 kt at
the surface. During the past hour, Doppler velocities have sharply
increased with numerous patches of 85-90 kt between 7000-8000 ft
common in the northern eyewall. Although these values would
typically correspond to surface winds of about 75 kt, the Doppler
velocity are occurring in low reflectivity regions of 25-30 dBZ, so
the full effect of those winds are likely not reaching the surface.
This could be why the highest SFMR surface wind observed by the
aircraft was only 63 kt. The initial intensity has been increased to
70 kt, which is a blend of the aircraft flight-level, radar, and
SFMR surface wind speed estimates.

The center position is a tad north of the recon fixes due to some
southward tilt of the eye caused by northerly shear. This has
resulted in a slower westward motion of 270/06 kt. The ridge to the
north of the hurricane has been slowly building westward and
southwestward based on upper-air data over the past 24 hours. This
slow ridging pattern is expected to continue for the next 48 hours,
resulting in Hanna gradually turning toward the west-southwest by
late this afternoon or evening, with landfall occurring in about 12
h along south Texas coast. After landfall, Hanna should continue
its west-southwestward motion until dissipation over the mountainous
terrain of northeastern Mexico in 48-60 h. The new NHC track
forecast is similar to the previous advisory track, and lies close
to the tightly packed consensus model guidance.

Although the deep-layer vertical wind shear is expected to remain
out of the north-northwest to north at about 20 kt, the relatively
large and stable eye, along with the expected convective vigor of
the hurricane, could result in a little more strengthening just
before landfall occurs. After landfall, rapid weakening of the wind
field is expected. However, the weakening peak winds will have no
negative effect on the likelihood for heavy rainfall or the
possibility of isolated tornadoes developing.


Key Messages

1. Life-threatening storm surge is occurring along portions of the
Texas coast from Port Mansfield to Sargent, where a Storm Surge
Warning is in effect. Residents in these locations should follow
advice given by local emergency officials.

2. Hurricane conditions are expected along the Texas coast from Port
Mansfield to Mesquite Bay, where a Hurricane Warning is in effect.
Tropical storm conditions are expected to first reach the coast
within the warning area this morning.

3. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains could result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of the eye of Hurricane Hanna
was located by reconnaissance aircraft and NOAA Doppler weather
radars near latitude 27.1 North, longitude 96.3 West. Hanna is
moving toward the west near 7 mph (11 km/h), and this motion should
continue through this morning. A gradual turn toward the
west-southwest is expected by late afternoon and tonight, and that
motion should continue through Sunday. On the forecast track, the
center of Hanna should make landfall along the Texas coast within
the hurricane warning area by late afternoon or early this evening.

Data from the NOAA Hurricane Hunter aircraft and Doppler weather
radars indicate that maximum sustained winds have increased to near
80 mph (130 km/h) with higher gusts. Some further strengthening is
possible before Hanna makes landfall later today. Rapid weakening is
expected after Hanna moves inland.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 90 miles
(150 km).

Reports from the NOAA Hurricane Hunter aircraft indicate that the
minimum central pressure is 978 mb (28.88 inches).


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

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Mesquite Bay including Corpus Christi Bay, Copano Bay,
and Aransas Bay...3-5 ft

Port Mansfield to Baffin Bay...2-4 ft

Mesquite Bay to Sargent including San Antonio Bay and Matagorda
Bay...2-4 ft

Mouth of the Rio Grande to Port Mansfield...1-3 ft

North of Sargent to High Island including Galveston Bay...1-2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are expected in the warning area
this afternoon. Tropical storm conditions are occuring in
portions of the warning area and will spread inland through the
afternoon and evening.

RAINFALL: Hanna is expected to produce 6 to 12 inches of rain with
isolated maximum totals of 18 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next couple of
days. These swells are likely to cause life-threatening surf and rip

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

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for...
* Port Mansfield to Sargent Texas

A Hurricane Warning is in effect for...
* Port Mansfield to Mesquite Bay Texas

A Tropical Storm Warning is in effect for...
* Barra el Mezquital Mexico to Port Mansfield Texas
* Mesquite Bay to High Island Texas

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 24 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area, in this case within the next 12
hours. 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, in this case within
the next 12 hours.

Interests elsewhere along the Texas and Louisiana coasts should
monitor the progress of Hanna. Interests in northeastern Mexico
should also monitor the progress of this system.

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 700 AM CDT (1200 UTC), the center of Hurricane Hanna was located
by reconnaissance aircraft and NOAA Doppler weather radars near
latitude 27.1 North, longitude 96.0 West. Hanna is moving toward
the west near 9 mph (15 km), and this motion should continue through
this morning. A gradual turn toward the west-southwest is expected
by tonight and that motion should continue through Sunday. On the
forecast track, the center of Hanna should make landfall along the
Texas coast within the hurricane warning area this afternoon or
early this evening.

Data from the reconnaissance aircraft and Doppler weather radars
indicate that maximum sustained winds have increased to near 75 mph
(120 km/h) with higher gusts. Additional strengthening is forecast
before Hanna makes landfall later today. Rapid weakening is expected
after Hanna moves inland.

Hurricane-force winds extend outward up to 25 miles (40 km) from
the center. Tropical-storm-force winds extend outward up to 90 miles
(150 km) from the center.

Data from the NOAA Hurricane Hunter aircraft indicate that the
minimum central pressure is 982 mb (29.00 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Port Mansfield to Baffin Bay TX...2 to 4 ft

Baffin Bay to Sargent TX...including Corpus Christi Bay, Copano Bay,
Aransas Bay, San Antonio Bay, and Matagorda Bay...3 to 5 ft

Mouth of the Rio Grande to Port Mansfield TX...1 to 3 ft

North of Sargent to High Island TX...including Galveston Bay...1 to
2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are expected in the warning area
this afternoon. Tropical storm conditions are expected to begin
in the warning area later this morning.

RAINFALL: Hanna is expected to produce 6 to 12 inches of rain with
isolated maximum totals of 18 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next couple of
days. These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible today and overnight over
parts of the lower to middle Texas coastal plain.

Tropical Storm Hanna Discussion Number 10
NWS National Hurricane Center Miami FL AL082020
400 AM CDT Sat Jul 25 2020

Hanna continues to become better organized on satellite images,
with an extensive area of cold cloud tops in both its Central Dense
Overcast and in banding features over the eastern and southern
parts of the circulation. Dvorak intensity estimates from TAFB and
SAB are at 55 kt, but with the continued increase in organization
over the past couple of hours, the current intensity is set at 60
kt. This is also in agreement with the latest objective Dvorak
estimate from UW-CIMSS. A NOAA Hurricane Hunter aircraft is
scheduled to investigate Hanna later this morning which should
provide a more precise intensity estimate. Since Hanna should
remain in an atmospheric and oceanic environment that is conducive
for strengthening up to landfall, the cyclone should become a
hurricane very soon. The NHC intensity forecast is close to the
model consensus.

The center is moving just slightly south of due west or around
265/8 kt. A mid-level subtropical high to the north of Hanna has
built a little and this should result in a turn toward the
west-southwest during the next 12-24 hours. After landfall, the
track guidance shows a continued west-southwestward motion until
dissipation over the mountainous terrain of northeastern Mexico.
The official track forecast has been adjusted just a bit to the
south of the previous forecast. This is just north of the
dynamical model consensus and just south of the latest ECMWF
track.

Based on the new official forecast track, the Storm Surge Warning
has been extended southward to Port Mansfield, Texas.


Key Messages

1. There is a danger of life-threatening storm surge along the Texas
coast from Port Mansfield to Sargent, where a Storm Surge Warning
is in effect. Residents in these locations should follow advice
given by local emergency officials.

2. Hurricane conditions are expected along the Texas coast from
Port Mansfield to Mesquite Bay, where a Hurricane Warning is in
effect. Tropical storm conditions are expected to first reach the
coast within the warning area this morning.

3. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains could result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

from the center.

The estimated minimum central pressure is 988 mb (29.18 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Port Mansfield to Baffin Bay TX...2 to 4 ft

Baffin Bay to Sargent TX...including Corpus Christi Bay, Copano Bay,
Aransas Bay, San Antonio Bay, and Matagorda Bay...3 to 5 ft

Mouth of the Rio Grande to Port Mansfield TX...1 to 3 ft

North of Sargent to High Island TX...including Galveston Bay...1 to
2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are expected in the warning area
this afternoon. Tropical storm conditions are expected to begin
in the warning area later this morning.

RAINFALL: Hanna is expected to produce 6 to 12 inches of rain with
isolated maximum totals of 18 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next couple of
days. These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

TORNADOES: A few tornadoes are possible today and overnight over
parts of the lower to middle Texas coastal plain.

DISCUSSION AND OUTLOOK
----------------------
At 100 AM CDT (0600 UTC), the center of Tropical Storm Hanna was
located near latitude 27.0 North, longitude 95.3 West. Hanna is
moving toward the west near 8 mph (13 km/h) and this motion should
continue through this morning. A gradual turn toward the
west-southwest is expected by tonight and that motion should
continue through Sunday. On the forecast track, the center of Hanna
should make landfall along the Texas coast within the hurricane
warning area this afternoon or early this evening.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts. Additional strengthening is forecast, and Hanna is expected
to become a hurricane before the cyclone makes landfall today.
Rapid weakening is expected after Hanna moves inland.

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

The estimated minimum central pressure is 991 mb (29.26 inches).

Tropical Storm Hanna Discussion Number 9
NWS National Hurricane Center Miami FL AL082020
1000 PM CDT Fri Jul 24 2020

Hanna continues to strengthen over the northwestern Gulf of Mexico.
Satellite and Doppler radar images indicate that the inner core
continues to become better organized and the outer bands are now
more symmetrical around the center. The NOAA Hurricane Hunters are
currently investigating Hanna and have found maximum 850 mb
flight-level winds of 72 kt and maximum SFMR winds of 51 kt. Based
on this data, the initial intensity is increased to 55 kt for this
advisory. The aircraft has also reported a minimum pressure of 992
mb, which is a 8 mb drop from the flight earlier today.

The NOAA aircraft data indicate that the center has moved a little
south of west during the past few hours, and the storm is now a
little south of the previous forecast track. A strengthening
subtropical ridge over the central U.S. should cause the storm to
continue to move generally westward, taking the center across the
southern Texas coast tomorrow afternoon or early evening. After
landfall, the storm is expected to turn to the west-southwest or
southwest across extreme southern Texas and northern Mexico, and
that motion should continue until the system dissipates.

Hanna still has another 18 hours or so to strengthen as it remains
in light wind shear conditions and over the warm Gulf of Mexico
waters. Since the structure of the system continues to improve, it
seems likely that Hanna will reach hurricane intensity before it
makes landfall. The peak intensity could be higher than what is
shown in the intensity forecast below since landfall is expected
to occur between the 12 and 24 h forecast times. After landfall,
rapid weakening is anticipated, and Hanna is expected to dissipate
on Monday over the rugged terrain of northern Mexico. The NHC
intensity forecast lies at the high end of the model guidance for
the next 24 h.

Key Messages

1. There is a danger of life-threatening storm surge along the Texas
coast from Baffin Bay to Sargent, where a Storm Surge Warning is in
effect. Residents in these locations should follow advice given by
local emergency officials.

2. Hurricane conditions are expected along the Texas coast from
Port Mansfield to Mesquite Bay, where a Hurricane Warning is in
effect. Tropical storm conditions are expected to first reach the
coast within the warning area Saturday morning.

3. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains could result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are expected in the warning area
Saturday afternoon. Tropical storm conditions are expected to begin
in the warning area later tonight or Saturday morning.

RAINFALL: Hanna is expected to produce 5 to 10 inches of rain with
isolated maximum totals of 15 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next couple of
days. These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

TORNADOES: A brief tornado or two will be possible, mainly
overnight, across portions of the upper Texas and Louisiana Coasts.

Tropical Storm Hanna Discussion Number 8
NWS National Hurricane Center Miami FL AL082020
400 PM CDT Fri Jul 24 2020

Satellite imagery, along with Doppler radar data from Houston and
Corpus Christi, indicate that Hanna has been getting better
organized over the past several hours. Curved banding features have
improved and a banding eye has developed in the radar data. The NOAA
reconnaissance aircraft reported SFMR winds of 43-45 kt on its last
outbound leg and a ship D5DE5 just east of the center reported an
elevated wind speed of 51 kt at 1400Z. Based on these data, along
with an estimated pressure of 999 mb from surrounding oil rigs, the
initial intensity has been conservatively increased to 45 kt.

Reconnaissance and radar fix data indicate that Hanna has turned
westward, and the motion is now 275/09 kt. Hanna is forecast to move
generally westward along the southern periphery of a deep-layer
ridge for the next 24 hours, with landfall expected along the
south-central coast of Texas within the hurricane warning area
Saturday afternoon or early evening. The new NHC forecast track is
just an extension of the previous advisory track, and lies close to
an average of the consensus models TVCN, NOAA-HCCA, and FSSE.

Given the improved internal structure noted in radar imagery, along
with SSTs of at least 30 deg C and an impressive outflow pattern,
increased frictional convergence as the cyclone moves closer to the
coast and the approaching nocturnal convective maximum should
support additional strengthening, and Hanna is now forecast
to become a hurricane prior to making landfall. The NHC forecast of
65 kt in 24 hours is between the latest HWRF model run, which
brings Hanna to 70 kt just prior to landfall, and the intensity
consensus models HCCA and IVCN, which are just below hurricane
strength.

Due to Hanna forecast to reach hurricane strength, Hurricane and
Storm Surge Warnings have been issued for portions of the Texas
coast.

Key Messages

1. There is a danger of life-threatening storm surge along the Texas
coast from Baffin Bay to Sargent, where a Storm Surge Warning is in
effect. Residents in these locations should follow advice given by
local emergency officials.

2. Hurricane conditions are expected along the Texas coast from
Baffin Bay to Mesquite Bay, where a Hurricane Warning is in effect.
Tropical storm conditions are expected to first reach the coast
within the warning area Saturday morning.

3. Hanna is expected to produce heavy rains across portions of
southern Texas and northeastern Mexico. These rains could result in
life-threatening flash flooding and isolated minor to moderate river
flooding.

DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Hanna was
located near latitude 27.3 North, longitude 94.3 West. Hanna is
moving toward the west near 10 mph (17 km/h), and this motion should
continue through Saturday morning. A gradual turn toward the
west-southwest is expected Saturday night and that motion should
continue through Sunday. On the forecast track, center of Hanna
should make landfall along the Texas coast within the
hurricane warning area Saturday afternoon or early evening.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Steady strengthening is forecast for the next 24 hours, and
Hanna is expected to become a hurricane before the cyclone makes
landfall. Steady to rapid weakening is expected after Hanna moves
inland.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure is 999 mb (29.50 inches)
based on nearby oil rig reports.


HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Sargent TX...including Corpus Christi Bay, Copano
Bay,
Aransas Bay, San Antonio Bay, and Matagorda Bay...2 to 4 ft
Mouth of the Rio Grande to Baffin Bay TX...1 to 3 ft
North of Sargent to High Island TX...including Galveston Bay...1 to
2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions are expected in the warning area
Saturday afternoon. Tropical storm conditions are expected to begin
in the warning area tonight or Saturday morning.

RAINFALL: Hanna is expected to produce 5 to 10 inches of rain with
isolated maximum totals of 15 inches through Sunday night in south
Texas and into the Mexican states of Coahuila, Nuevo Leon, and
northern Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next few days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

TORNADOES: A brief tornado or two will be possible, mainly
overnight, across portions of the upper Texas and Louisiana Coasts.

landfall along the Texas coast within the warning area Saturday
afternoon or evening.

Maximum sustained winds have increased to near 50 mph (85 km/h)
with higher gusts. Additional strengthening is expected until the
tropical cyclone makes landfall. Steady weakening is expected after
Hanna moves inland.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center. During the past couple of hours, a ship located
just east of the center reported a sustained wind of 46 mph (74
km/h).

The estimated minimum central pressure is 999 mb (29.50 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Hanna can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.

WIND: Tropical storm conditions are expected in the warning area
by tonight or Saturday morning.

RAINFALL: Hanna is expected to produce 4 to 8 inches of rain with
isolated maximum totals of 12 inches through Sunday night in south
Texas. This rain may result in life-threatening flash flooding,
rapid rises on small streams, and isolated minor to moderate river
flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts, and inland to the Mexican states of Coahuila,
Nuevo Leon, and northern Tamaulipas.

STORM SURGE: The combination of storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...

Mouth of the Rio Grande to High Island including Corpus Christi Bay,

Tropical Storm Hanna Discussion Number 7
NWS National Hurricane Center Miami FL AL082020
1000 AM CDT Fri Jul 24 2020

Reports from a NOAA reconnaissance aircraft this morning and nearby
ship D5DY4 indicate that Hanna has strengthened a little. However,
the aircraft data also showed that Hanna's center had moved or
reformed a little farther north near the northern edge of the
convective cloud mass. A partial SSMI/S pass around 1231Z suggested
that a mid-level eye feature could be forming, but it also possible
that a dry slot may be intruding into the cloud shield from the
northwest and west. The initial intensity of 40 kt is based on
aircraft SFMR surface winds of 38-40 kt, and the 1200Z D5DY5 ship
report of 48 kt at 89 meters elevation, which reduces to a 38-kt
10-meter wind speed.

Even with the earlier northwestward jump in the center position,
reconnaissance and microwave satellite data indicate that Hanna's
motion is still west-northwestward or 285/08 kt. There remains no
significant change to the previous official track forecast or
reasonings over the past couple of days. The latest NHC model
guidance remains in good agreement that mid-level ridge will build
to the north and northwest of Hanna over the next couple of days,
resulting in the cyclone turning westward by tonight and on
Saturday. It should then turn west-southwestward Saturday night and
Sunday. The new NHC forecast track continues to show the center
making landfall along the south-central coast of Texas within the
tropical storm warning area Saturday afternoon or evening, which is
in good agreement with the various consensus models.

Hanna's convective cloud shield remains very asymmetrical with the
bulk of the convection confined to the southern semicircle despite
the otherwise symmetrical and expanding upper-level outflow pattern.
More recently, some deep convection has developed near the center
and the aforementioned possible mid-level eye feature. Hanna is
forecast to remain in relatively low vertical wind shear regime and
over SSTs of 30C or more, a combination that typically favors
significant intensification. However, nearby dry mid-level air noted
in 1200Z soundings from Corpus Christi and Brownsville has been
eroding and preventing convection from developing in the northwest
quadrant and near the center, which has inhibited strengthening over
the past couple of days despite the low shear conditions. The latest
global model guidance shows the dry air mixing out in about 24 h
just prior to landfall, which should allow for at least gradual
strengthening until landfall occurs in about 30 h or so. However, if
an eyewall forms during the next 12 h, then it is possible that
Hanna could be near 60 kt when it makes landfall. The new NHC
intensity forecast is similar to the previous advisory, and is a
blend of the IVCN and HCCA consensus intensity forecasts.


Key Messages

1. Hanna is forecast to strengthen and it is expected to
bring tropical-storm-force winds to portions of the Texas coast,
where a tropical storm warning is in effect.

2. Hanna is expected to produce heavy rains across portions of
southern Texas. These rains could result in flash flooding and
isolated minor to moderate river flooding.

has been discontinued.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Mouth of the Rio Grande to San Luis Pass Texas

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

Interests along the Texas and Louisiana coast should monitor the
progress of this system.

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 1000 AM CDT (1500 UTC), the center of Tropical Storm Hanna was
located by NOAA reconnaissance aircraft near latitude 27.2 North,
longitude 93.2 West. Hanna is moving toward the west-northwest near
9 mph (15 km/h), and this motion should continue today. A turn
toward the west is expected tonight, followed by a westward to
west-southwestward motion through the weekend. On the forecast
track, center of Hanna should make landfall along the Texas coast
within the warning area Saturday afternoon or evening.

Maximum sustained winds have increased to near 45 mph (75 km/h)
with higher gusts. Gradual strengthening is expected until the
tropical cyclone makes landfall. Steady weakening is expected after
Hanna moves inland.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center. During the past few hours, a ship located east of
the center reported a sustained wind of 44 mph (70 km/h).

Reports from the NOAA reconnaissance aircraft indicate that the
minimum central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Hanna can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.

WIND: Tropical storm conditions are expected in the warning area
by tonight or Saturday morning.

RAINFALL: Hanna is expected to produce 4 to 8 inches of rain with
isolated maximum totals of 12 inches through Sunday night in south
Texas. This rain may result in life-threatening flash flooding,
rapid rises on small streams, and isolated minor to moderate river
flooding in south Texas.

3 to 5 inches of rain is expected along the upper Texas and
Louisiana coasts, and inland to the Mexican states of Coahuila,
Nuevo Leon, and northern Tamaulipas.

STORM SURGE: The combination of storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...

Mouth of the Rio Grande to High Island including Corpus Christi Bay,
Matagorda Bay, and Galveston Bay...1-3 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to
your area, please see products issued by your local National
Weather Service forecast office.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next few days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Tropical Storm Hanna Discussion Number 6
NWS National Hurricane Center Miami FL AL082020
400 AM CDT Fri Jul 24 2020

Satellite imagery shows well-defined convective banding features
over the eastern and southern portions of the circulation with some
cooling of the cloud tops. This suggests that the associated
thunderstorm activity is becoming more vigorous. However, surface
observations over the Gulf and a scatterometer pass from a few
hours ago indicate that the system has not strengthened further at
this time. The current intensity estimate is held at 35 kt in
agreement with a Dvorak classification from TAFB. A NOAA Hurricane
Hunter aircraft is scheduled to investigate the storm later this
morning and they should provide a good estimate of Hanna's
intensity. The storm has an impressive upper-level anticyclonic
outflow structure and should remain in a low shear environment
until it reaches the coast. Therefore strengthening is likely
prior to landfall and the NHC intensity forecast is near the model
high end of the intensity model suite.

The storm has moved a little faster toward the west-northwest over
the past several hours, and the initial motion estimate is 290/8
kt. There is very little change to the official track forecast or
reasoning from the previous cycle. A gradual turn toward the west
is likely in 12 hours or so as a mid-level ridge to the north of
Hanna builds a bit. The forecast track takes the center inland
over Texas within the tropical storm warning area on Saturday.
This is in good agreement with the dynamical model consensus and
the latest ECMWF model solution.


Key Messages

1. Hanna is forecast to strengthen and it is expected to
bring tropical-storm-force winds to portions of the Texas coast,
where a tropical storm warning is in effect.

2. Hanna is expected to produce heavy rains across portions of
southern Texas. These rains could result in flash flooding and
isolated minor to moderate river flooding.

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

The Tropical Storm Warning has been extended southward from Port
Mansfield Texas to the Mouth of the Rio Grande.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Warning is in effect for...
* Mouth of the Rio Grande to San Luis Pass Texas

A Tropical Storm Watch is in effect for...
* San Luis Pass to High Island Texas

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

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests along the Texas and Louisiana coast should
monitor the progress of this system. Tropical Storm Warnings may
be required for portions of the Watch area later today.

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 1000 PM CDT (0300 UTC), the center of Tropical Storm Hanna was
located near latitude 26.2 North, longitude 91.4 West. Hanna is
moving toward the west-northwest near 7 mph (11 km/h) and a
west-northwestward to westward motion is expected during the
next couple of days. On the forecast track, the center of the
storm is expected to move across the northwestern Gulf of
Mexico on Friday and make landfall along the Texas coast on
Saturday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Additional strengthening is expected until the system makes
landfall. Steady weakening is expected after Hanna moves inland.

Tropical-storm-force winds extend outward up to 35 miles (55 km)
from the center.

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


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Hanna can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.

WIND: Tropical storm conditions are expected in the warning area
by Friday night or Saturday morning. Tropical storm conditions are
possible within the watch area by Friday night or Saturday morning.

RAINFALL: Hanna is expected to produce 3 to 5 inches of rain with
isolated maximum totals of 10 inches through Monday along the Gulf
Coast of the United States from Louisiana to south Texas, and inland
to the Mexican states of Coahuila, Nuevo Leon, and northern
Tamaulipas. This rain may result in life-threatening flash
flooding, rapid rises on small streams, and isolated minor to
moderate river flooding.

SURF: Swells generated by Hanna are expected to increase and affect
much of the Texas and Louisiana coasts during the next few days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Tropical Storm Hanna Discussion Number 5
NWS National Hurricane Center Miami FL AL082020
1000 PM CDT Thu Jul 23 2020

The system continues to organize with curved bands becoming
better established around the center. The cyclone certainly has
the appearance of a tropical storm, and just minutes ago the NOAA
Hurricane Hunters found winds to support upgrading the system to a
35-kt tropical storm. Data from the aircraft also show that the
minimum pressure has dropped to 1002 mb, indicating that the system
is on a developing trend.

Hanna is moving fairly slowly to the west-northwest, with
the latest initial motion estimated to be 285/6 kt. This
west-northwest motion should continue on Friday, but a turn to the
west is expected by Friday night as a subtropical ridge strengthens
to the north of the cyclone. This steering flow should take the
center of the storm across the southern Texas coast in 36 to 48
hours. After landfall, the storm is forecast to turn south of west
across extreme southern Texas and northern Mexico. The models have
shifted southward again this cycle, and the NHC track forecast has
been adjusted in that direction.

Additional strengthening seems quite likely until the storm makes
landfall since it is expected to remain over the very warm Gulf of
Mexico waters and in generally low wind shear conditions. After
landfall, steady weakening should commence, and the cyclone should
dissipate over the rugged terrain of northern Mexico in about 4
days. The NHC intensity forecast is a little above the previous one
and at the high end of the guidance given the system's well
organized structure and favorable environment.

Due to the southward shift in the track forecast, the tropical
storm warning has been extended southward from Port Mansfield to
the Mouth of the Rio Grande.

Tropical Storm Hanna is the earliest 8th storm on record. The
previous record was in 2005 when Harvey formed on August 3rd.


Key Messages

1. Hanna is forecast to strengthen and it is expected to
bring tropical-storm-force winds to portions of the Texas coast,
where a tropical storm warning is in effect.

2. Hanna is expected to produce heavy rains across portions of
Louisiana, southern Texas, and northern Mexico. These rains could
result in flash flooding and isolated minor-to-moderate
river flooding.

life-threatening flash flooding, rapid rises on small streams, and
isolated minor-to-moderate river flooding.

SURF: Swells generated by the tropical cyclone are expected to
increase and affect much of the Texas and Louisiana coasts during
the next few days. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Tropical Depression Eight Discussion Number 4
NWS National Hurricane Center Miami FL AL082020
400 PM CDT Thu Jul 23 2020

Satellite imagery indicates that the depression continues to become
better organized, with the center near the eastern edge of a large
and broadly curved convective area, with a second curved band to
the east. Several subjective and objective satellite intensity
estimates have increased to 35 kt since the last advisory.
However, surface observations, scatterometer data, and data from an
earlier Air Force Reserve Hurricane Hunter mission show a large
area of 25-30 kt winds south and east of the center, and no 35-kt
winds to justify an upgrade at this time. Thus, the initial
intensity remains 30 kt. A NOAA Hurricane Hunter aircraft is
scheduled to investigate the depression this evening, and the
current expectation is that they will find it is a tropical storm.

The center meandered a bit today, possibly due to reformation.
However, the system now seems to have resumed a west-northwestward
motion of 285/7 kt. A mid-level ridge over the central United
States is the predominant steering influence, and the global models
forecast this ridge to build somewhat during the next several days.
This should cause the depression to turn westward by 36-48 h
and south of west after about 60 h. The track guidance remains in
good agreement with that scenario, although there has been a
slight southward shift in the guidance envelope and the
consensus models. The new NHC forecast track is also shifted
a little southward and has the center making landfall along the
Texas coast in about 48 h.

The depression is in an environment of light shear with good
anticyclonic outflow, and it will be over warm sea surface
temperatures until landfall. This should allow steady
strengthening. The new NHC intensity forecast has been increased
to show a peak intensity of 50 kt just before landfall, followed by
steady weakening and eventually dissipation after landfall. The new
intensity forecast is close to the intensity consensus.

The aircraft and scatterometer data show that the strongest winds
in the cyclone are currently occurring about 70-90 n mi from the
center. This has caused the forecast wind radii to be expanded,
and as a result a Tropical Storm Warning is needed for portions of
the Texas coast.


Key Messages

1. The depression is expected to strengthen and it is likely to
bring tropical-storm-force winds to portions of the Texas coast,
where a tropical storm warning has been issued.

2. The tropical cyclone is expected to produce heavy rains across
portions of Louisiana, southern Texas, and northern Mexico. These
rains could result in flash flooding and isolated minor-to-moderate
river flooding.

Tropical Depression Eight Discussion Number 3
NWS National Hurricane Center Miami FL AL082020
1000 AM CDT Thu Jul 23 2020

Satellite imagery indicates that the depression is getting better
organized, with a better-defined center located near the
northeastern end of a broadly curved convective band. Satellite
intensity estimates from TAFB and SAB have increased to 30 kt, and
that will be the initial intensity for this advisory. An Air Force
Reserve Hurricane Hunter aircraft is currently enroute to
investigate the depression.

The initial motion is west-northwestward or 285/8 kt. A mid-level
ridge over the central United States is the predominant steering
influence, and the global models forecast this ridge to build
during the several days. This should cause the depression to turn
more westward by 48-60 h and south of west after about 72 h. The
track guidance is in good agreement with that scenario, and the new
NHC forecast track, which has only minor adjustments from the
previous track, lies near the various consensus models. The new
forecast track has the center making landfall along the Texas coast
between 48-60 h.

The depression is in an environment of light shear and over warm
sea surface temperatures, so at least slow strengthening is
expected until landfall. The new intensity forecast, which lies a
little below the intensity consensus, now calls for a peak
intensity of 45 kt before landfall. Data from the Hurricane Hunter
will give more details on whether the structure of the cyclone has
improved or not, which will be incorporated into the next forecast
cycle.


Key Messages

1. The depression is expected to strengthen and it could bring
tropical-storm-force winds to portions of the Texas coast, where a
tropical storm watch is in effect.

2. The depression is expected to produce heavy rains along the Gulf
Coast from Louisiana to the Lower Texas Coast. These rains could
result in flash flooding and minor river flooding.

DISCUSSION AND OUTLOOK
----------------------
At 1000 AM CDT (1500 UTC), the center of Tropical Depression Eight
was located near latitude 26.3 North, longitude 90.7 West. The
depression is moving toward the west-northwest near 9 mph (15 km/h),
and a west-northwestward to westward motion is expected during the
next couple of days. On the forecast track, the center of the
depression is expected to move across the northwestern Gulf of
Mexico today and Friday and make landfall along the Texas coast
on Saturday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Slow strengthening is expected, and the depression could become a
tropical storm during the next 12 to 24 hours. An Air Force
Reserve Hurricane Hunter aircraft is currently enroute to
investigate the depression.

The estimated minimum central pressure is 1007 mb (29.74 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are possible within the watch
area by Friday night.

RAINFALL: The tropical depression is expected to produce 3 to 5
inches of rain with isolated maximum totals of 8 inches through
Monday along the Gulf Coast from Louisiana to the Lower Texas Coast,
and inland through south-central Texas and the Rio Grande Valley.
This rain may result in flash flooding, rapid rises on small
streams, and isolated minor flooding across the west-central Gulf
Coast and into portions of south Texas.

SURF: Swells generated by the depression are expected to increase
and affect much of the Texas and Louisiana coasts in a day or two.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.

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

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Watch is in effect for...
* Port Mansfield to High Island Texas

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere along the Texas and Louisiana coast should
monitor the progress of this system.

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 700 AM CDT (1200 UTC), the center of Tropical Depression Eight
was located near latitude 26.0 North, longitude 90.4 West. The
depression is moving toward the west-northwest near 9 mph (15 km/h),
and this general motion is expected during the next few days. On
the forecast track, the center of the depression is expected to move
across the northwestern Gulf of Mexico today and Friday and make
landfall along the Texas coast on Saturday.

Maximum sustained winds are near 30 mph (45 km/h) with higher
gusts. Slow strengthening is expected, and the depression could
become a tropical storm in a day or so.

The estimated minimum central pressure is 1007 mb (29.74 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are possible within the watch
area by late Friday.

RAINFALL: The tropical depression is expected to produce 3 to 5
inches of rain with isolated maximum totals of 8 inches through
Monday along the Gulf Coast from Louisiana to the Lower Texas Coast,
and inland through south-central Texas and the Rio Grande Valley.
These rains may result in flash flooding across the west-central
Gulf Coast into portions of south Texas.

SURF: Swells generated by the depression are expected to increase
and affect much of the Texas and Louisiana coasts in a day or two.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.

Tropical Depression Eight Discussion Number 2
NWS National Hurricane Center Miami FL AL082020
400 AM CDT Thu Jul 23 2020

Satellite images and surface synoptic observations suggest that
the depression has not strengthened thus far, although recent
images show some increase in deep convection near the estimated
center. The initial intensity estimate remains at 25 kt in
agreement with surface data over the Gulf. The cyclone should
remain in a relatively moist, low-shear environment during the next
day or so. However, since the system is not well organized, only
slow strengthening is forecast until the center reaches the coast.
The NHC intensity forecast is near the upper range of the model
guidance at this time.

The center is not well-defined and the initial motion estimate is
an uncertain 290/8 kt. This is more or less consistent with
observations from NOAA data buoy 42001 over the central Gulf. A
continued west-northwestward track is expected over the next day or
so followed by a slight bend toward the west in response to some
building of a mid-level ridge to the north of the cyclone. The
official track forecast is a little faster than the previous one but
not quite as fast as the latest dynamical model consensus.


Key Messages

1. The depression is expected to strengthen and it could bring
tropical-storm-force winds to portions of the Texas coast, where a
tropical storm watch has been issued.

2. The depression is expected to produce heavy rains across
portions of Louisiana and southern Texas. These rains could result
in flash flooding.

Tropical Depression Eight Discussion Number 1
NWS National Hurricane Center Miami FL AL082020
1000 PM CDT Wed Jul 22 2020

Surface observations and data from the Air Force Hurricane Hunters
indicate that the area of low pressure over the central Gulf of
Mexico has developed a closed circulation and a well-defined
center. In addition, recent satellite images show an area of deep
convection expanding over the center. Based on those observations,
advisories are being initiated on Tropical Depression Eight. The
initial intensity is set at 25 kt based on the earlier
reconnaissance data.

The initial motion is an uncertain west-northwestward at 5 kt. A
subtropical ridge to the northeast of the depression should cause
it to continue moving in that general direction through Friday as
it tracks across the northwestern Gulf of Mexico. A slight turn to
the left is expected Friday night and Saturday as a ridge builds to
the north of the system, taking the center of cyclone across the
Texas coast and then inland over southern Texas. The models are in
fairly good agreement on this scenario, and the NHC track forecast
lies near the various consensus models.

The depression is expected to be in generally light to moderate
wind shear conditions, in a fairly moist environment, and over the
warm waters of the Gulf of Mexico for the next couple of days, so
some strengthening seems likely. However, since the depression is
still in its formative stage, the rate of strengthening should be
gradual. After the storm crosses the coast, steady weakening should
commence. The NHC intensity forecast generally follows the IVCN and
HCCA guidance.

Key Messages

1. The depression is expected to strengthen and it could bring
tropical-storm-force winds to portions of the Texas coast, where a
tropical storm watch has been issued.

2. The depression is expected to produce heavy rains across
portions of Louisiana and southern Texas. These rains could result
in flash flooding.
