San Antonio residents face a soggy end to the holiday weekend as storms bring heavy rainfall and a flood watch into Labor Day. Low water crossings, creeks, and major highways like I-35 and I-10 could see dangerous conditions starting Sunday afternoon and lasting through Monday. Officials urge drivers to avoid flooded roadways and prepare for rapidly changing conditions.
According to the National Weather Service in Austin/San Antonio, widespread thunderstorms will push across south central Texas through Monday. Rainfall totals between two and six inches are possible, with some areas seeing up to eight inches. The heaviest downpours are expected late Sunday night into early Monday morning, leading to flash flooding in poor drainage areas and urban streets.
Counties under the flood watch include Bexar, Guadalupe, Comal, Medina, Bandera, and Travis. San Antonio, Seguin, New Braunfels, and Boerne could experience delays on roads as water rises quickly. With holiday travel underway, extra caution is advised for those heading to events or returning home.
