Houston, Texas – A surge of tropical moisture threatens Southeast Texas with heavy rainfall, flash flooding, and strong thunderstorms through Saturday, raising concerns for drivers and residents in Houston, Galveston, Baytown, and surrounding communities.
According to the National Weather Service, a marginal to slight risk of excessive rainfall is in place east of I-45 on Friday and Saturday as a tropical disturbance in the northeastern Gulf moves toward the region. Houston, Galveston, League City, Baytown, and Livingston face the highest rain chances, with up to a 70% probability on Friday. The National Hurricane Center currently gives this system a 40% chance of developing into a tropical depression.
Flood-prone roads in Houston, Bay City, and Galveston may see water accumulations, especially during heavy downpours on Friday afternoon and evening. Conroe, Livingston, and Katy could also experience quick rises in small creeks and urban flooding. Residents are urged to avoid driving through water-covered roads, keep emergency kits handy, and charge electronic devices in case of power outages.
Temperatures will remain in the low-to-mid 90s, with high humidity making conditions uncomfortable for outdoor activity. The last time the region saw similar flooding potential in July was 2021, which led to multiple road closures and high water rescues.
Threats may linger into Saturday night, especially along and east of I-45. More advisories could be issued if the tropical system strengthens or slows.
