Flood Watch Issued for South Central Texas Through Tuesday Evening

June 15, 2026 · wweather1 editorial · 2 min read

The National Weather Service (NWS) Austin/San Antonio has issued a Flood Watch for portions of south central Texas. The watch is in effect from June 14 at 9:31 PM CDT until June 16 at 7:00 PM CDT, indicating potential for flooding caused by excessive rainfall.

The Flood Watch, issued by NWS Austin/San Antonio TX, covers a portion of south central Texas. Counties included in the watch are Atascosa, Bandera, Bastrop, Bexar, Blanco, Burnet, Caldwell, Comal, De Witt, Dimmit, Edwards, Fayette, Frio, Gillespie, Gonzales, Guadalupe, Hays, Karnes, Kendall, Kerr, Kinney, Lavaca, Lee, Llano, Maverick, Medina, Real, Travis, Uvalde, Val Verde, Williamson, Wilson and Zavala. The NWS advises that flooding caused by excessive rainfall continues to be possible.

The watch began on June 14 at 9:31 PM CDT and will remain in effect through Tuesday evening, concluding on June 16 at 7:00 PM CDT. There is a potential for life threatening flooding somewhere within the watch area. Excessive runoff may lead to flooding of rivers, creeks, streams, and other low-lying or flood-prone locations.

Creeks and streams may rise out of their banks, and low-water crossings could become flooded. Humid tropical air combined with a stalling front is expected to bring heavy rain. Isolated pockets may see rain totals of 8 inches or more, with rain rates potentially exceeding 2 to 3 inches per hour at times.
