Flood watch issued for Kerr County, much of South Central Texas through Thursday

The National Weather Service issued a flood watch Monday morning for Kerr County and 20 other South Central Texas counties, warning that a slow-moving weather system could bring life-threatening flooding through Thursday evening.

The watch takes effect at 9 p.m. Monday and runs through Thursday evening. It covers Bandera, Bexar, Blanco, Burnet, Comal, Dimmit, Edwards, Frio, Gillespie, Hays, Kendall, Kerr, Kinney, Llano, Maverick, Medina, Real, Travis, Uvalde, Val Verde, Williamson and Zavala counties.

Forecasters said tropical moisture interacting with a slow-moving upper-level disturbance and outflow boundaries will fuel an active weather pattern across the region tonight through at least Thursday evening. Storm totals of 2 to 6 inches are possible across the watch area, with isolated totals as high as 10 inches. The highest rainfall totals are expected mainly over the Rio Grande Plains and southern Edwards Plateau, though the watch area — including Kerr County — remains at risk.

The weather service said excessive runoff could send rivers, creeks and streams out of their banks, with flooding possible in low-lying areas, poor drainage areas and urban areas. Low-water crossings may flood, and the agency warned of the potential for extensive street flooding.

The weather service urged residents to monitor later forecasts and be alert for possible flood warnings, and said those in flood-prone areas should be prepared to take action if flooding develops.
