Houston, Texas – Drivers across southeast Texas could encounter water-covered roads by midafternoon Sunday as storms intensify west of the Houston metro, bringing rainfall rates capable of overwhelming drainage systems within minutes.
According to the National Weather Service in Houston/Galveston, a secondary system will push into the region Sunday, increasing storm coverage after noon with a Level 2 of 4 risk for excessive rainfall across the Brazos Valley and Piney Woods. Rain chances climb as high as 70% in cities like College Station and Brenham between 3 p.m. and 7 p.m., where repeated storms may track over the same areas.
Western counties including Washington, Brazos, and Burleson face the highest flood concern, with localized totals potentially exceeding 2 inches in a short window. In the Houston metro, including Katy, Baytown, and League City, rain chances hover between 25% and 45%, but brief downpours could still cause ponding on I-10, I-45, and the 610 Loop.
Storms may also turn severe at times, producing wind gusts over 50 mph, small hail, and an isolated tornado risk, especially west of Houston near Columbus and College Station.
Residents should avoid flooded roadways, charge devices ahead of storms, and monitor alerts closely through Sunday night as conditions can shift quickly. Additional advisories remain possible into the evening hours.
