The National Weather Service has issued a flash flood watch from 7 p.m. this evening until noon Tuesday along and east of U.S. 83. Moist Gulf air, an upper level trough, and a cold front will combine to bring showers and thunderstorms to the area late this afternoon through Tuesday night.
Overall, expect widespread rainfall of 2 to 4 inches, with isolated totals of 5 to 7 inches. These heavy rains could occur in a 2-4 hour period, which will produce flash flooding in urban areas and for rivers such as the Sabinal, Frio, and Nueces, as rain on the headwaters flows downstream and combines with falling rain to produce a higher flood wave.
This flash flood watch remains in effect from 7 p.m. this evening through Tuesday morning for these counties in South Central Texas, Atascosa, Bandera, Bastrop, Bexar, Blanco, Burnet, Caldwell, Comal, Dewitt, Dimmit, Fayette, Frio, Gillespie, Gonzales, Guadalupe, Hays, Karnes, Kendall, Kerr, Lavaca, Lee, Llano, Medina, Real, Travis, Uvalde, Williamson, Wilson, and Zavala. While massive rainfall amounts and devastating floods are not expected, there is still a significant threat for driving into floodwaters at low-water crossings in the Hill Country and in low-lying spots in urban areas.
Never drive where water covers the road. Slow down at night or anytime visibility is poor. Save your own life. Turn around; don‘t drown.
