This product covers Southeast Texas

EDOUARD BECOMING BETTER ORGANIZED AS IT APPROACHES THE COAST NEAR THE TEXAS
AND LOUISIANA BORDER.

NEW INFORMATION
---------------

* CHANGES TO WATCHES AND WARNINGS:
- A Tropical Storm Warning has been issued for Southern Liberty

* CURRENT WATCHES AND WARNINGS:
- A Tropical Storm Warning is in effect for Bolivar Peninsula,
Chambers, and Southern Liberty

* STORM INFORMATION:
- About 120 miles east of Galveston TX
- 29.0N 92.8W
- Storm Intensity 40 mph
- Movement West-northwest or 300 degrees at 8 mph

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

Tropical Storm Edouard is showing signs of strengthening as it
approaches the Upper Texas Coast. The system's outer rainbands are
already reaching the coastline near High Island and Galveston. These
rainbands will continue to push into our southeastern coastal counties
this morning, before pushing farther inland this afternoon and evening.
The system is forecast to become a strong tropical storm before moving
ashore near Sabine, TX early this afternoon. The primary concern for
our area will be heavy rainfall. The heaviest showers and thunderstorms
could produce 3-4" per hour rainfall rates, which would result in
flash flooding. Worth mentioning that residual tropical moisture could
result in scattered heavy showers and thunderstorms on Wednesday as well.

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

* WIND:
- POTENTIAL IMPACTS: Limited but track dependent
- Potential for some tree damage within the Tropical Storm Warning area,
especially if the center deviates west of the track.
- Scattered power and communications outages are possible.


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

* SURGE:
No significant impacts from surge are expected.



* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across southeast Texas. Potential
impacts include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Streams and bayous may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots and where heavy rainbands occur.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
become hazardous. Some road and bridge closures.



* TORNADOES:
Tornado threat appears to be very low at this time.

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

* OTHER PREPAREDNESS INFORMATION:


Rapidly rising flood waters are deadly. Never drive through a flooded
roadway. Remember, turn around don't drown!


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.

conditions warrant.
