...FLASH FLOOD WATCH IN EFFECT FROM THIS EVENING THROUGH THURSDAY EVENING...

Tropical moisture from Imelda will move across the region through Thursday. Bands around the system may produce prolonged periods of heavy rain which may quickly overwhelm drainage systems in metro areas.

* Flash Flood Watch for portions of southwest Louisiana and southeast Texas, including the following areas, in southwest Louisiana, Beauregard, Calcasieu, East Cameron, and West Cameron. In southeast Texas, Hardin, Jefferson, Northern Jasper, Northern Newton, Orange, Southern Jasper, Southern Newton, and Tyler.

* From 7 PM CDT this evening through Thursday evening

* 2 to 6 inches of rainfall in far Southwest Louisiana with isolated higher amounts. 4 to 9 inches of rain is forecast for Southeast Texas with 12 inches or more possible in isolated locations.

* Heavy rainfall in a short period of time may overwhelm drainage systems causing flooding of streets and low lying areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 1 PM CDT WEDNESDAY...

...Minor Coastal Flooding at Times of High Tide...

An area of disturbed weather will continue to move into the Central Texas coast through tonight and Wednesday. This will provide tide levels of 1.5 to 2 feet above normal tide levels which may produce minor flooding of coastal locations at times of high tide through Wednesday morning.


...SMALL CRAFT ADVISORY IN EFFECT UNTIL 1 AM CDT WEDNESDAY...

* WINDS...around 20 knots with higher gusts.

SUMMARY OF 400 PM CDT...2100 UTC...INFORMATION
----------------------------------------------
LOCATION...29.3N 95.3W
ABOUT 30 MI...50 KM W OF GALVESTON TEXAS
ABOUT 30 MI...45 KM SSE OF HOUSTON TEXAS
MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H
PRESENT MOVEMENT...N OR 360 DEGREES AT 7 MPH...11 KM/H
MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES

At 400 PM CDT (2100 UTC), the center of Tropical Storm Imelda was located near latitude 29.3 North, longitude 95.3 West. Imelda is moving toward the north near 7 mph (11 km/h) and this general motion is expected to continue through early Wednesday. A north- northwestward motion is expected Wednesday night and Thursday. On the forecast track, the center of Imelda will continue to move farther inland across eastern Texas tonight and Wednesday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Imelda is expected to weaken to a tropical depression as it moves farther inland.

Tropical-storm-force winds extend outward up to 45 miles (75 km) mainly to the southeast of the center over water. A wind gust to 40 mph (65 km/h) was recently reported in Galveston, Texas.

The estimated minimum central pressure is 1006 mb (29.71 inches).

For more information, visit the National Hurricane Center webpage.
Periods of heavy rain will be a possibility through mid-week as Tropical Storm Imelda slowly weakens while moving inland in SE TX. 2 to 6 inches of rainfall is possible in far SW LA with isolated higher amounts. 4 to 9 inches of rain is forecast for SE TX with 12 inches or more possible in isolated locations. Ponding on roadways and low lying areas, in addition to flash flooding, will be a possibility.
Overnight: Tropical Storm Imelda continues to slowly move inland into SE TX, and as a result, fairly widespread rain is expected through SE TX and into far SW LA. Further east and north, rain chances will be more on the scattered side through the overnight hours. Otherwise, a bit muggy with temperatures ranging from the upper 70s near the coast to lower 70s further inland.
Wednesday: Rain becomes more widespread as slow moving Tropical Storm Imelda continues inland. Periods of heavy rain, especially where any bands set up, will need to be monitored for potential flash flooding, and as such a Flash Flood Watch will be in effect. Otherwise, expect temperatures to be cooler than usual due to the rain and associated cloud cover.
