Austin, Texas – Repeated rounds of thunderstorms could dump several inches of rain across parts of South-Central Texas through Thursday, raising the threat of flash flooding, especially west of San Antonio and across the Rio Grande Plains.
According to the National Weather Service in Austin/San Antonio, widespread rainfall totals of 2 to 6 inches are possible from Monday through Thursday. The greatest concern is centered over the Rio Grande Plains and southern Edwards Plateau, where isolated totals as high as 8 inches could fall if thunderstorms repeatedly track over the same locations.
Communities including Del Rio, Langtry, Rocksprings, Eagle Pass, Uvalde and surrounding areas are most likely to experience the heaviest rainfall. Farther east, including San Antonio, Austin, New Braunfels, Georgetown and Gonzales, rainfall totals will generally range from 0.5 to 1.5 inches, though localized heavier amounts are possible beneath stronger storms.
Heavy rainfall over a short period could quickly overwhelm low-water crossings, creeks and urban drainage systems, leading to dangerous flash flooding. Travel conditions may deteriorate rapidly where storms repeatedly develop.
Residents are urged to closely monitor weather forecasts throughout the week and have multiple ways to receive warnings. If you encounter a flooded roadway, Turn Around, Don’t Drown. The National Weather Service notes that just 12 inches of moving water can carry away a small car, while 18 to 24 inches can sweep away most SUVs and trucks.
Additional flood watches or flash flood warnings may be issued as rainfall develops through Thursday.
