Flood Watch Issued for South-Central Texas as Heavy Rainfall Threatens Flash Flooding

A flood watch is in effect for a large swath of South-Central Texas, including major cities like Austin and San Antonio, as an approaching storm system promises notable rainfall and the potential for dangerous flash floods. The watch, beginning late Wednesday night, comes as communities brace for conditions reminiscent of earlier severe weather events this year.

Heightened Risk Following Earlier Flooding

The region is particularly vulnerable following devastating floods and severe storms experienced earlier in 2025, most notably in Kerr County. Forecasters are warning that even moderate rainfall could quickly overwhelm rivers, creeks, and drainage infrastructure, creating hazards for homes, roadways, and overall public safety. The potential for loss of life and widespread evacuations, already realized earlier this year, underscores the gravity of the current situation.

Did you know? – Flash floods can develop rapidly, often within minutes, and are the leading cause of weather-related deaths. Be aware of your surroundings and heed all warnings.

Counties Under Watch & Rainfall Forecast

According to the National Weather Service (NWS), the flood watch encompasses Bandera, bexar, Bell, Blanco, Brown, Burnet, Bosque, Comal, Comanche, Coryell, Edwards, Hamilton, Gillespie, Hays, Kendall, kimble, Kerr, Kinney, Llano, Lampasas, Mason, Medina, McLennan, McCulloch, Menard, mills, Real, San Saba, Sutton, Travis, Uvalde, Val Verde, and Williamson counties.

The impending weather is driven by an upper-level storm system interacting with unusually high levels of atmospheric moisture. The NWS forecasts rainfall amounts of 1 to 3 inches, with the possibility of isolated totals reaching 6 to 8 inches. This runoff is expected to cause flooding in rivers, creeks, streams, and low-lying areas.Urban areas with poor drainage and low-water crossings are also considered particularly at risk.

pro tip: – If you encounter a flooded roadway, “Turn Around, Don’t Drown.” Never attempt to drive or walk through floodwaters.Even shallow water can be deceptively dangerous.

Flash Flood threat & Regional Impact

A moderate risk – a 40 percent or greater probability – of flash flooding is also in effect for portions of the region, including Del Rio and Rocksprings.

The NWS Austin and San Antonio office shared rainfall projections on X (formerly Twitter) on Wednesday, stating: “Thes are the most likely rainfall amounts most can expect late tonight through early Friday morning. The highest totals are expected over the southern Edwards Plateau and the western Hill Country. A Flood Watch goes into effect midnight tonight until 6
