Western Dimmit County in south central Texas...
Western Uvalde County in south central Texas...
Western Zavala County in south central Texas...
* Until 1215 AM CDT
* At 909 PM CDT, Doppler radar indicated thunderstorms producing
heavy rain west of a Concan to Carrizo Springs line and east of a
25 miles northwest of Brackettville to Quemado to El Indio line.
Up to 3.5 inches of rain have already fallen. Flash flooding is
expected to begin shortly.
* Some locations that will experience flooding include...
Eagle Pass, Uvalde, Crystal City, Carrizo Springs, Brackettville,

dangers of flooding.
Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying

Remain alert for flooding even in locations not receiving rain.
Arroyos, streams, and rivers can become raging killer currents in a
matter of minutes, even from distant rainfall.
