The National Weather Service has issued a flash flood watch from 4 p.m. Monday through Tuesday morning for Bexar County and the following counties:

Atascosa, Bandera, Blanco, Caldwell, Comal, Fayette, Frio, Gillespie, Gonzales, Guadalupe, Hays, Kendall, Kerr, Medina, Real, Uvalde, Wilson and Zavala.

KSAT Meteorologist Adam Caskey said a flash flood watch means conditions are favorable for flash flooding, but it's not happening at the moment. A warning means it's actually occurring.
