Weather Information

The National Weather Service (NWS) has extended a Flash Flood Watch for Houston until 7.00am Thursday morning. This means conditions are favorable for flooding to occur.

Widespread rainfall has fallen from remnants of Tropical Storm Imelda. The National Weather Service forecasts additional storms developing this afternoon across parts of the southeast Texas region.

Protective Actions

Be Prepared. People should bring their pets inside and delay travel or outdoor activities during periods of heavy rainfall. If travel is unavoidable, reduce your speed to avoid hydroplaning.

If a Flash Flood Warning is issued for your area, DO NOT travel.

Property owners should ensure that street drains and ditches are clear of debris, so storm water can flow without obstructions. Blockages of drains, ditches, and culverts are the most frequent cause of flooding in neighborhoods.

Secure items that might float away in heavy rain and become lodged in drains or culverts. Avoid street parking to protect your vehicle and allow clear passage for response vehicles.

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.
