AlertHouston | Flash Flood Warning for Southwest Houston Until 1:30 AM

Flash Flood Warning for Southwest Houston Until 1:30 AM

Weather Information
The National Weather Service has issued a Flash Flood Warning for portions of southwest Houston until 1:30 a.m.  This means that flash flooding is in progress, imminent, or very likely.

At 11:35 p.m., Doppler radar and automated rain gauges indicated thunderstorms producing heavy rain across the warned area. This storm is capable of producing another 1 inch of rain over the next hour. Some areas in the warning have already had 3 to 5 inches of rainfall. 

Additional rainfall will make flooding worse. Flash flooding is even more dangerous during the night time since you cannot see how high water is on roads.

Protective Actions
Take Action.  DO NOT Travel. Wait until the threat of high water has passed.

Turn Around, Don't Drown®:  Do not drive through flooded areas.  If you see water covering the road, do not attempt to cross it.  Only a few inches of water can float a vehicle. If you find yourself in a dangerous situation where your vehicle is taking on water, get out of the vehicle, get to a higher position, and call 911.   

Monitor Official Sources for Current Information:  Harris County Flood Warning System (, Houston TranStar (, and the National Weather Service Houston/Galveston Forecast Office (

Monitor Stream, Bayou, and Creek Conditions:  Rain may move repeatedly across the same area, causing creeks and bayous to rise and possibly exceed their banks.  Stay informed of current conditions and avoid traveling near creeks and bayous.

Avoid Traveling during Periods of Heavy Rain:  Rain can reduce visibility and prevent you from seeing the road ahead, which could lead to accidents.
