2026-07-17T12:00:00-05:00

* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...A portion of south central Texas, including the following counties, Bandera, Blanco, Dimmit, Edwards, Frio, Gillespie, Kendall, Kerr, Kinney, Llano, Maverick, Medina, Real, Uvalde, Val Verde and Zavala. * WHEN...Through Friday morning. * IMPACTS...There is a potential for life threatening flooding somewhere in the watch area. Considerable to locally catastrophic flash flooding impacts are likely for the southern Edwards Plateau, Rio Grande, Hill Country, and US 90 corridor west of San Antonio. Excessive runoff will result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Catastrophic impacts are possible downstream of the heaviest rains. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Intense rainfall rates and compounding effects from multiple rounds of storms will maintain a dangerous flash flood threat through Friday morning. Additional rain amounts of 2 to 4 inches are possible within the Flood Watch area with isolated amounts up to 8 inches possible in the Rio Grande Plains, southern Edwards Plateau, Hill Country, and US 90 corridor west of San Antonio. - http://www.weather.gov/safety/flood
