Monday night the National Weather Service slapped a flash flood warning on parts of Guadalupe County and urged people in low‑lying areas to move to higher ground. The advisory called out Luling, Stairtown, Belmont and stretches of I‑10 and State Highway 183, and it remained in effect into the late evening.
TxDOT San Antonio quickly boosted the alert on X, retweeting the Weather Service's message and warning motorists to be ready for sudden roadway flooding in those corridors. The post on X repeats the NWS safety guidance, according to TxDOT San Antonio.
Where the Warning Applied
The advisory covered portions of Guadalupe County and nearby routes that are known to see quick street and creek flooding, according to the National Weather Service Austin/San Antonio. The agency's product and social posts listed the named communities in the county and urged extra caution for drivers in those areas.
Officials' Advice
The NWS told residents to "move immediately to higher ground" and to "avoid walking or driving through flood waters," language that TxDOT echoed when sharing the alert. Officials also pushed the familiar "Turn Around, Don't Drown" campaign as a reminder that most flood deaths happen in vehicles, according to the National Weather Service Austin/San Antonio.
Outlook and Travel Impacts
Local meteorologists warned that rounds of heavy rain could keep rolling through Thursday, with widespread totals of 1 to 3 inches likely and isolated spots picking up more. That raises the risk of street and creek flooding across the area. The forecast and the broader flood watch for the region were outlined by local outlets and weather teams, as reported by MySA.
Drivers are urged to avoid flooded stretches altogether and to keep an eye on official feeds for changing conditions. TxDOT and local emergency departments post travel advisories as situations develop. For the latest warnings and road information, see TxDOT San Antonio.
