Southeast Texas is bracing for heavy rainfall through Friday evening, with weather experts warning about the increased risk of flash flooding. This storm system is expected to bring major disruptions to travel and affect several counties along the Gulf Coast.
Flood Watch Issued for Southeast Texas
The National Weather Service (NWS) Houston/Galveston office has placed parts of southeast Texas under a Flood Watch until 7 p.m. on Friday. The warning mainly covers areas south of I-10 and west of I-45, including Matagorda, Jackson, Wharton, and Fort Bend counties.
Forecasters say that most areas can expect between 2 to 5 inches of rain, but some places may receive up to 9 inches.
Risk of Flash Flooding and Travel Disruptions
As rain pours down, flash flooding is a serious concern, especially in low-lying areas and neighborhoods that flood easily. The storm could lead to dangerous driving conditions on major highways like I-69, Highway 59, and US 290, with potential for water to quickly fill lanes and cause full closures.
Drivers are being strongly advised not to attempt crossing flooded roads and to stay off the roads during periods of heavy rain.
Highest Flood Threat in Matagorda and Jackson Counties
The greatest risk of flooding is focused on Matagorda and Jackson counties. A moderate flood risk has been issued for these areas, while a slight flood risk could stretch toward Houston and nearby regions by Friday morning.
River levels near the Tres Palacios, San Bernard, and Navidad Rivers may briefly rise above safe levels. However, experts say that widespread river flooding is not expected at this time.
Safety Tips for Residents
Officials are asking everyone in southeast Texas to remain alert. Residents in flood-prone areas should have emergency kits ready, avoid unnecessary travel, and follow updates from local authorities. If you see flooded roads while driving, turn around and find another route. Even a small amount of moving water can be enough to sweep a car off the road.
It’s also wise to charge phones, keep flashlights and batteries handy, and check weather updates regularly from trusted sources like weather.gov/houston.
The ongoing rainfall is expected to test the region’s flood control systems. While not every area will see severe impacts, the potential for flash flooding makes it important to take this weather event seriously.
People in affected counties should stay safe, avoid flooded roads, and keep an eye on weather alerts as conditions can change quickly. With smart precautions, many of the dangers posed by this heavy rain can be avoided.
