Post-Tropical Cyclone Arthur Discussion Number 8
NWS National Hurricane Center Miami FL AL012026
1000 PM CDT Wed Jun 17 2026

Surface observations indicated that the center of Arthur re-formed
near Galveston around 21-22Z in response to an offshore convective
burst. Since that time, there has been no organized convection near
the center, and the circulation has become elongated along the Upper
Texas coast. Based on these developments, and the expectation that
organized convection will not reform near the center, Arthur is no
longer a tropical cyclone and is being downgraded to a post-tropical
low with 30 kt winds.

While the motion is a bit uncertain due to the center reformation,
it appears that the system is starting to move a bit faster toward
the northeast with the initial motion estimated at 040/8 kt. A
general northeastward motion is expected until the surface center
dissipates tonight over southeastern Texas or southwestern
Louisiana. After that, the remnants of Arthur should move east-
northeastward across the southeastern United States and emerge into
the Atlantic on Friday. A continued east-northeastward motion out to
sea is expected thereafter.

As mentioned, the surface center of Arthur is expected to dissipate
later tonight. The global models suggest that the surface center
could reform near the Atlantic coast on Friday, with some
intensification possible as the system moves out to sea. It is
unclear at this time whether this re-development will be due to
tropical cyclone processes or baroclinic process. However, marine
gale warnings are being issued for portions of the western Atlantic
in anticipation of this development.

Even though Arthur is no longer a tropical cyclone, heavy rainfall
and life-threatening flash flooding will continue to be a major
hazard for the next few days across the southeastern United States.
There is also an increased tornado threat for portions of the
southeastern U.S. through Thursday.

That is the last advisory issued by the National Hurricane Center on
this system. Rainfall forecasts for the remnants of Arthur in the
United States can be found at
https://www.wpc.ncep.noaa.gov/qpf/qpf2.shtml and outlooks of flash
flood risks can be found at
https://www.wpc.ncep.noaa.gov/qpf/excessive_rainfall_outlook_ero.php
.
Marine forecasts, including gale warnings, can be found in High Seas
Forecasts issued by the National Weather Service, under AWIPS header
NFDHSFAT1, WMO header FZNT01 KWBC, and online at
ocean.weather.gov/shtml/NFDHSFAT1.php.


KEY MESSAGES:

1. Potentially life-threatening flash flooding and urban flooding
are likely through Friday across southern Louisiana, southern
Mississippi, southern Alabama, southwestern Georgia, and the Florida
Panhandle. Scattered minor river flooding is expected, with the
potential for isolated moderate to major river flooding. Ongoing
heavy rainfall could prolong the flood threat through the weekend.

2. Wind gusts to tropical-storm force could occur along portions
of the Louisiana coast tonight.

3. Coastal flooding along the coasts of Texas and Louisiana should
gradually subside later tonight and Thursday.

DISCUSSION AND OUTLOOK
----------------------
At 1000 PM CDT (0300 UTC), the center of Post-Tropical Cyclone
Arthur was located near latitude 29.7 North, longitude 94.5 West.
The post-tropical cyclone is moving toward the northeast near 9 mph
(15 km/h). A northeastward motion at a faster forward speed is
expected tonight, followed by a turn toward the east-northeast
Thursday through Friday. On the forecast track, the remnants of
Arthur should move farther inland over southeastern Texas and
western Louisiana tonight, then cross the southeastern United States
Thursday through Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
While additional weakening is expected as the system moves inland,
the remnants of Arthur will continue to produce widespread heavy
rains across the southeastern United States during the next few
days.

The estimated minimum central pressure based on surface observations
is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for remnants of Arthur can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header
WTNT41 KNHC.

RAINFALL: Arthur is expected to produce rainfall totals of 5 to 10
inches, with isolated higher totals near 20 inches, through early
Friday from the Mid and Upper Texas coast east-northeast into
southern and central portions of Louisiana, Mississippi, and
Alabama, along with western portions of Georgia and the Florida
Panhandle. This could generate dangerous to life-threatening flash
flooding.

DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the center of Tropical Storm Arthur was
located near latitude 29.4 North, longitude 94.9 West. Arthur is
moving erratically toward the northeast near 8 mph (13 km/h). A
northeastward to north-northeastward motion should continue through
tonight. On the forecast track, the center of Arthur should move
farther inland over southeastern Texas tonight.

Maximum sustained winds are now near 40 mph (65 km/h) with higher
gusts. Weakening is expected as the center of Arthur moves farther
inland, and it could dissipate later tonight or early Thursday.

Tropical-storm-force winds extend outward up to 175 miles (280 km)
mainly to the southeast of the center. An oil rig well to the
southeast of the center recently reported sustained winds of 38 mph
(61 km/h) at an elevation of 135 ft (41 m).

The estimated minimum central pressure is 1000 mb (29.53 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Arthur can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header
WTNT41 KNHC.

RAINFALL: Tropical Storm Arthur is expected to produce rainfall
totals of 5 to 10 inches, with isolated higher totals near 20
inches, through early Friday from the Mid and Upper Texas coast
east-northeast into southern and central portions of Louisiana,
Mississippi, and Alabama, along with western portions of Georgia and
the Florida Panhandle. This could generate dangerous to
life-threatening flash flooding.

For a complete depiction of forecast rainfall associated with
Tropical Storm Arthur, please see the National Weather Service Storm
Total Rainfall Graphic available at
hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at1.shtml?ero.

with Tropical Storm Arthur, see the companion storm summary at
WBCSCCNS1 with the WMO header ACUS44 KWBC or at the following link:
www.wpc.ncep.noaa.gov/discussions/nfdscc1.html.

WIND: Tropical storm conditions are expected within the warning area
during the next few hours.

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...

Matagorda, TX to the Mouth of the Mississippi River, LA...1-3 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. 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.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at1.shtml?peakSurge.

SURF: Swells generated by Arthur are likely to cause
life-threatening surf and rip current conditions along the
northwestern Gulf Coast for the next day or two. Please consult
products from your local weather office.

Tropical Storm Arthur Discussion Number 7
NWS National Hurricane Center Miami FL AL012026
400 PM CDT Wed Jun 17 2026

The center of Arthur appears to have moved inland over Matagorda
County, Texas, early this afternoon based on visible satellite
images and surface observations. However, the circulation center has
become more diffuse and less defined over the past couple hours,
making it difficult to track with much confidence. A large area of
deep convection persists over the northwestern Gulf of America, but
strong westerly shear has displaced it even farther from the center.
Marine observations and data from the NOAA Hurricane Hunters show
tropical-storm-force winds are still ongoing within this convection
well to the east and southeast of the center. Based on a blend of
the aircraft data and available surface observations, the initial
intensity is held at 40 kt.

The low-level mean center has deviated more northward than expected
today, and the long-term motion estimate is north-northeastward at
about 6 kt. Most models suggest the circulation center will
dissipate within the next 6-12 h, but a continued motion toward the
north-northeast is forecast for Arthur or its low-level remnants
through tonight. This updated track forecast has shifted left
(farther inland) due to the center relocation this afternoon.
However, this is of little consequence as the greatest impacts from
Arthur are still being felt well to the east of its center.

Now that the center of Arthur is inland, weakening is expected
while it contends with strong westerly shear and some drier
mid-level air infiltrating from the west. Model-simulated satellite
imagery from the GFS and ECMWF suggest the associated convection
should mostly collapse tonight. The 12-h forecast point shows
remnant low status, but it could just as likely dissipate before
that time. The ECMWF and Canadian models still suggest a potential
for low pressure development over the western Atlantic late this
week or this weekend as remnant vorticity from Arthur emerges off
the Southeast U.S. coast. However, it is unclear how tropical in
nature this system would be if it were to develop, so we will
continue to monitor model trends.

Heavy rainfall and life-threatening flash flooding remain the
primary hazard, and it is stressed that this threat extends well
away from the center and will persist even after Arthur dissipates.
There is also an increased tornado threat for portions of the
southeastern U.S. through Thursday.


KEY MESSAGES:

1. Potentially life-threatening flash flooding and urban flooding
are likely through Friday across southern Louisiana, southern
Mississippi, southern Alabama, southwestern Georgia, and the Florida
Panhandle. Scattered minor river flooding is expected, with the
potential for isolated moderate to major river flooding. Ongoing
heavy rainfall could prolong the flood threat through the weekend.

2. Tropical-storm-force winds, especially in gusts, are expected
along the Upper Texas and Louisiana coasts during the next few
hours where a Tropical Storm Warning is in effect.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines today.

HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Arthur can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header
WTNT41 KNHC.

RAINFALL: Tropical Storm Arthur is expected to produce rainfall
totals of 5 to 10 inches, with isolated higher totals near 20
inches, through early Friday from the Mid and Upper Texas coast
east-northeast into southern and central portions of Louisiana,
Mississippi, and Alabama, along with western portions of Georgia and
the Florida Panhandle. This could generate dangerous to
life-threatening flash flooding.

For a complete depiction of forecast rainfall associated with
Arthur, please see the National Weather Service Storm Total Rainfall
Graphic available at hurricanes.gov/graphics_at1.shtml?rainqpf and
the Flash Flood Risk graphic at
hurricanes.gov/graphics_at1.shtml?ero.

For a list of rainfall observations (and wind reports) associated
with Arthur, see the companion storm summary at WBCSCCNS1 with the
WMO header ACUS44 KWBC or at the following link:
www.wpc.ncep.noaa.gov/discussions/nfdscc1.html.

WIND: Tropical storm conditions are expected within the warning area
today.

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 Bolivar, TX to Morgan City, LA...2-4 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. 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.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at1.shtml?peakSurge.

SURF: Swells generated by Arthur are likely to cause
life-threatening surf and rip current conditions along the
northwestern Gulf Coast for the next day or two. Please consult
products from your local weather office.

A depiction of rip current risk for the United States can be found
at: hurricanes.gov/graphics_at1.shtml?ripCurrents

TORNADO: A couple of tornadoes are possible through Thursday from
the Upper Texas Coast into southern Louisiana, Mississippi, Alabama,

Tropical Storm Arthur Special Discussion Number 6
NWS National Hurricane Center Miami FL AL012026
1130 AM CDT Wed Jun 17 2026

This special advisory is being issued to extend the Tropical Storm
Warning for the Upper Texas coast southward to Sargent, Texas.
Recent surface observations and NOAA buoy 42035 indicate that
maximum sustained winds are near 40 kt, and the estimated minimum
pressure has fallen to 999 mb. No changes have been made to the
track or intensity forecasts. The regularly scheduled intermediate
advisory will be issued by 1800 UTC.

Previous Discussion:
The low pressure area near the Middle Texas coast has produced
sustained convection well to the east of its center this morning. A
1200 UTC TAFB Dvorak classification indicated enough convective
organization to designate the system as a sheared tropical cyclone.
Within the past hour or two, buoy observations and a ship report
have indicated tropical-storm-force winds occurring within this
convection. Additionally, Air Force Reserve Hurricane Hunters
investigating the storm found peak 850-mb flight-level winds up to
52 kt, which also suggest this system has reached tropical storm
intensity. Based on these findings, the system is designated as
Tropical Storm Arthur with an intensity of 35 kt.

Arthur is starting to accelerate northeastward (045/8 kt) within
strengthening southwesterly flow associated with a low- to mid-level
trough. There are no significant changes to the track forecast
reasoning, with a faster northeastward motion expected today that
will move the center of the system along or over the Texas coast
today and then farther inland over southeastern Texas and
southwestern Louisiana by tonight. With no major changes to the
track guidance this cycle, the updated NHC forecast is very similar
to the previous one.

Given the unrelenting westerly shear and Arthur's close proximity to
land, it seems unlikely that much additional strengthening will
occur. The tropical-storm-force winds are confined to the eastern
semicircle and mainly occurring over the offshore waters. Arthur
will likely maintain its intensity while it remains over water, and
then weaken by tonight once it moves inland. Global model fields
indicate it will open into a trough soon thereafter, and although a
24-h forecast point is included mainly for continuity purposes,
Arthur should dissipate before that time. There is still a signal in
the global models for low pressure development over the western
Atlantic late this week or this weekend as remnant vorticity from
Arthur emerge off the Southeast U.S. coast. The exact nature of this
low remains unclear, so we will continue to monitor model trends to
evaluate the potential for tropical cyclone formation.

Heavy rainfall and life-threatening flash flooding remain the
primary hazard with this system. Based on recent observations, the
Tropical Storm Warning has been extended westward along the Upper
Texas coast to High Island.


KEY MESSAGES:

1. Potentially life-threatening flash flooding and urban flooding
are likely through Friday across southern Louisiana, southern
Mississippi, southern Alabama, southwestern Georgia, and the Florida
Panhandle, with possible flooding near the Upper Texas coast.
Ongoing heavy rainfall could prolong the flood threat into the
weekend.

2. Tropical-storm-force winds are expected along the Upper Texas
and Louisiana coasts today from High Island to Morgan City where a
Tropical Storm Warning is in effect.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines today.

Potential Tropical Cyclone One Discussion Number 4
NWS National Hurricane Center Miami FL AL012026
400 AM CDT Wed Jun 17 2026

The center of the low pressure area is very near the Middle Texas
coast, and offshore buoy observations indicate that maximum winds
remain 25 kt. A line of deep convection has formed over the
northwestern Gulf waters since the last advisory, but due to strong
westerly shear, this activity is located more than 120 n mi to the
east/southeast of the low-level center. As a result, the latest
Dvorak classification from TAFB is Too Weak To Classify, meaning
the system does not have the convective organization necessary to
be designated as a tropical cyclone.

The current motion is northeastward, or 045/5 kt. The system is
embedded in strengthening low- to mid-level southwesterly flow, and
with another trough approaching from the northwest, it is expected
to accelerate northeastward today. The track guidance has shifted
slightly westward on this cycle, and the center of the low is
therefore likely to straddle the Texas coast for much of the day,
before moving farther inland over eastern Texas or Louisiana
tonight. The NHC official track has been nudged westward, close to
the TVCN and HCCA consensus aids.

The prospects for this system to become a tropical cyclone may be
decreasing. With the low-level center unlikely to fully emerge
over the Gulf waters for an appreciable amount of time, and 25-30
kt of westerly shear expected to continue for the next 12 hours, it
will be difficult for the system to gain the convective
organization necessary to become a tropical cyclone before it moves
inland tonight. Even if the system doesn't become a tropical
cyclone, there could still be some strengthening of the wind field
well east of the center during the day, and the NHC official
forecast will continue to show a peak of 35 kt in 12 hours. After
that, all of the global models now show the system opening up into a
trough over Louisiana by tonight. The official forecast shows the
system as a remnant low at 24 hours, but it's entirely possible it
will have dissipated by then.

The global models show the remnant low-level vorticity continuing
eastward across the Southeast U.S. on Thursday and Friday, and the
ECMWF, Canadian, and UKMET models indicate that a low pressure
system could redevelop, especially once the system moves offshore
over the western Atlantic. The exact nature of this low is unclear
at this time, but we will monitor model trends for the possibility
of tropical cyclone formation over the western Atlantic late this
week or this weekend.

Regardless of whether the system becomes a tropical cyclone, heavy
rainfall and life-threatening flash flooding will be the primary
hazards with this system.


KEY MESSAGES:

1. Potentially life-threatening flash flooding and urban flooding
are likely through Thursday across southern Louisiana, southern
Mississippi, southern Alabama, southwestern Georgia and the Florida
Panhandle, with possible flooding near the Upper Texas coast.
Ongoing heavy rainfall could prolong the flood threat into the
weekend.

2. Tropical-storm-force winds are expected along the Louisiana
coast today from Sabine Pass to Morgan City where a Tropical
Storm Warning is in effect.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines today.

Potential Tropical Cyclone One Discussion Number 3
NWS National Hurricane Center Miami FL AL012026
1000 PM CDT Tue Jun 16 2026

The center of the system is beginning to emerge into the
northwestern Gulf. Surface observations do not show very strong
winds over the area at this time, and the current intensity is held
at 25 kt. This is consistent with a Dvorak classification from
TAFB. There is significant westerly vertical wind shear over the
disturbance, with most of the deep convection displaced well away
from the center of the low. Given that there has been no noticeable
increase in the deep convective organization of the disturbance, it
is being maintained as a potential tropical cyclone for this
advisory.

Based on the center fixes, the initial motion estimate, 050/5 kt, is
similar to that from the previous advisory. There has been little
change in the track model guidance. The system is expected to
accelerate northeastward in the flow on the southern and
southwestern side of a broad mid-level trough over the eastern
United States. The official forecast track shows the disturbance or
storm moving just offshore of, and parallel to, the Texas coast
during the next day or so. Then the system is likely to go back
onshore late Wednesday or Wednesday night. No significant change
has been made to the track forecast for this advisory, and the
official forecast is fairly close to the corrected consensus
solution.

The center should move far enough offshore on Wednesday for some
intensification to occur due to a combination of warm Gulf waters
and upper-level divergence. However the SHIPS guidance diagnoses
fairly strong shear over the area during the next 24-36 hours which
should limit strengthening up to landfall. The NHC forecast
continues to indicate the system becoming a tropical storm tomorrow,
which is also shown in the IVCN intensity model consensus.

Regardless of whether the system becomes a tropical cyclone, heavy
rainfall and life-threatening flash flooding will be the primary
hazards with this system.


KEY MESSAGES:

1. Potentially life-threatening flash and urban flooding is likely
through Thursday across Louisiana and southern Mississippi, and is
possible near the Upper Texas coast. Flash flooding is also
possible across Alabama, Georgia, and the Florida Panhandle through
the end of the week. Prolonged rainfall may extend the flood threat
into the weekend.

2. Tropical-storm-force winds are expected along the Louisiana
coast on Wednesday from Sabine Pass to Morgan City where a Tropical
Storm Warning is in effect.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines.

WIND: Tropical storm conditions are possible within the watch
area beginning early Wednesday, and are expected within the warning
area beginning on Wednesday morning.

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 Bolivar, TX to Morgan City, LA...2-4 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. 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.

Potential Tropical Cyclone One Discussion Number 2
NWS National Hurricane Center Miami FL AL012026
400 PM CDT Tue Jun 16 2026

The low pressure area continues to produce disorganized deep
convection mostly over water, almost exclusively in the eastern
semicircle. However, the low-level center has become better
defined during the day according to satellite and surface data,
along with falling pressures. While the system is fairly close to
transitioning into a tropical depression, it is still a bit shy of
a well-defined center and consistent convection. Thus the system
remains a potential tropical cyclone, and the initial intensity
is 25 kt based on surface and radar data.

The low continues to slowly move northeastward. It is expected to
move offshore of south Texas tonight and accelerate northeastward
along the coast on Wednesday due to the system encountering faster
flow associated with a mid-latitude trough over the eastern United
States. Model guidance is about the same as before, moving very
near the Texas coast on Wednesday before going back onshore late
Wednesday or Wednesday night. No significant changes were
made to the track forecast. The circulation is expected to
quickly dissipate over central Louisiana on Thursday.

The center should move far enough offshore on Wednesday for some
intensification to occur due to a combination of warm Gulf waters
and upper-level jet dynamics. Most of the guidance show the system
becoming a tropical storm tomorrow, and the official forecast is
basically an update of the previous one.

Regardless of whether the system becomes a tropical cyclone, heavy
rainfall and life-threatening flash flooding will be the primary
hazards with this system.


KEY MESSAGES:

1. Potentially life-threatening flash and urban flooding is likely
through Thursday across Louisiana and southern Mississippi, and is
possible near the Upper Texas coast. Flash flooding is also
possible across Alabama, Georgia, and the Florida Panhandle through
the end of the week. Prolonged rainfall may extend the flood
threat into the weekend.

2. Tropical-storm force winds are expected along the Louisiana
coast on Wednesday from Sabine Pass to Morgan City where a Tropical
Storm Warning is now in effect.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines.

Potential Tropical Cyclone One Discussion Number 1
NWS National Hurricane Center Miami FL AL012026
1000 AM CDT Tue Jun 16 2026

The disturbance (AL90) that we have been tracking for several days
across the southern Gulf of America into northeastern Mexico has
moved into southern Texas. While the system is producing plentiful
convection, it still lacks a well-defined center. However, most of
the guidance suggest that it will move offshore tonight, and winds
will increase to tropical-storm-force on Wednesday. Thus,
advisories have been initiated on Potential Tropical Cyclone One,
and Tropical Storm Watches have been issued for portions of the
Upper Texas and southwestern Louisiana coasts. Regardless of
whether the system becomes a tropical cyclone, heavy rainfall and
life-threatening flash flooding will be the primary hazards
with this system. The initial intensity is set at 25 kt, based on
surface and radar data.

The system is moving slowly northeastward this morning. We expect
the low to continue moving in that general direction with some
increase in forward speed due to it encountering faster flow
associated with a flat mid-latitude trough over the eastern United
States. Model guidance hugs the Texas coast but generally keeps
it offshore for about a day on Wednesday before moving back onshore
late Wednesday or early Thursday. The NHC forecast is between the
latest dynamical model consensus and the corrected-model consensus
HCCA.

The upper-level environment is not particularly conducive for much
intensification with a fair bit of shear and close proximity to
land. However, there is enough upper-level support from a jet to
the north to cause large-scale deepening, along with convective
support from warm Gulf waters, so some intensification is
anticipated through Wednesday. This forecast is similar to the
model consensus IVCN. It should be noted that this system will
likely never have a pure tropical appearance on satellite due to the
upper trough and shear, with a highly asymmetric appearance with the
rainfall and winds favoring the eastern semicircle.


KEY MESSAGES:

1. Potentially life-threatening flash and urban flooding is possible
across the Texas coast eastward into central Mississippi through
Thursday. Prolonged rainfall may extend the flood threat into the
weekend. Widespread small stream and minor river flooding is
expected along the Texas coast into southwest Louisiana, with
isolated areas of significant river flooding possible across the
Texas Coast and Louisiana.

2. Potential Tropical Cyclone One is forecast to become a tropical
storm as it moves along or just off the northwestern Gulf coast
through Wednesday. Tropical Storm Watches have been issued from
Sargent, Texas, to Morgan City, Louisiana.

3. Minor to moderate coastal flooding is expected along portions of
the Upper Texas and Louisiana coastlines.
