Houston, Texas – Drivers across southeast Texas could face sudden street flooding and dangerous lightning strikes by Saturday evening as storms push into the region ahead of a cold front.
According to the National Weather Service in Houston/Galveston, showers and thunderstorms are moving south through the Brazos Valley and Piney Woods this afternoon, reaching the Houston metro by late day and continuing through the evening. A marginal severe risk covers most of southeast Texas, while a slight risk of excessive rainfall targets areas north and northwest of Houston.
Rainfall totals will average between 0.75 and 1.5 inches north of I-10, with isolated pockets reaching 2 to 3 inches in stronger cells. That level of rainfall could overwhelm drainage systems, especially along busy corridors like I-10, U.S. 290, and Beltway 8. Strong wind gusts, frequent lightning, and brief downpours may reduce visibility below safe driving levels within minutes.
Communities including College Station, Conroe, and Livingston face the highest chance of heavier rainfall, while coastal areas like Galveston may see lower totals but still deal with lightning and gusty conditions. Marine impacts include elevated winds and choppy seas near thunderstorms.
Residents should avoid flooded roadways, secure outdoor items, and keep multiple ways to receive alerts as conditions can shift quickly through the evening. Additional warnings may be issued with little lead time as storms intensify.
