Flash Flood Safety

This is the current radar display for SE TX.

A Flood Watch has been issued for portions of southeast Texas through Wednesday evening.

Periods of heavy showers and thunderstorms are likely over the next several days. The risk of heavy rainfall and flooding includes the entire region. However, the highest risk of flooding will be across our southern and coastal counties, where there is a Level 3 of 4 (Moderate) risk of excessive rainfall capable of flash flooding through Wednesday.

National Weather Service graphic updated June 16, 2026, issuing a Tropical Storm Warning for the Southeast Texas Coast and adjacent Gulf waters, and a Tropical Storm Watch for Brazoria, Galveston, and Chambers Counties, including Galveston Bay. The text warns of expected winds over 40 mph in rainbands and highlights locally heavy rainfall and flash flooding as primary concerns.

This infographic highlights that flash flooding is a rapid, highly dangerous hazard that can catch people off guard whether they are driving or camping. It emphasizes the importance of proactive preparedness by advising people to enable mobile weather alerts, immediately seek higher ground when warned, and never attempt to cross flooded areas by foot or in a vehicle.
