SITUATION OVERVIEW
------------------

An area of low pressure centered over south Texas will move over
the western gulf tonight into Wednesday where it is expected
to develop into a tropical depression or weak tropical storm before
making landfall along the southeast Texas or southwest Louisiana coasts
Wednesday evening into Wednesday night. A tropical storm warning has
been issued for coastal portions of Louisiana and the adjacent coastal waters.
A Tropical Storm Watch remains in effect for Southeast Texas. Flash flooding
is already ongoing and additional long duration heavy rainfall from the tropical
cyclone will exacerbate flooding across southeast Texas as well as southwest,
central and south central Louisiana Wednesday and Thursday. Rainfall totals of
8-10 inches are expected in some areas. Coastal flooding with surge values of
2-4 feet are expected Wednesday. Wind gusts of 25-40 MPH can be expected along the
southwest and south central Louisiana coasts with wind gusts up to 25 MPH inland.

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across Southwest Louisiana and Southeast Texas.
Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, and ditches may
become dangerous rivers. Flood control systems and barriers may
become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal portions of southeast Texas as well as southwest and south central Louisiana.
Potential impacts in this area include:
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
- Major beach erosion with heavy surf breaching dunes. Strong and
numerous rip currents.
- Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially in
unprotected anchorages.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* WIND:
Protect against hazardous wind having possible limited impacts across
coastal portions of southwest and south central Louisiana.
Potential impacts in this area include:
- Damage to porches, awnings, carports, sheds, and unanchored
mobile homes. Unsecured lightweight objects blown about.
- Many large tree limbs broken off. A few trees snapped or
uprooted, but with greater numbers in places where trees are
shallow rooted. Some fences and roadway signs blown over.
- A few roads impassable from debris, particularly within urban
or heavily wooded places. Hazardous driving conditions on
bridges and other elevated roadways.
- Scattered power and communications outages.

Elsewhere across Southwest Louisiana and Southeast Texas, little to
no impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southwest Louisiana and Southeast Texas. Potential impacts
include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and boats pulled
from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Follow the advice of local officials.

* OTHER PREPAREDNESS INFORMATION:

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
