Flood Watch Issued for South Central Texas
The National Weather Service in Austin/San Antonio has issued a Flood Watch for portions of south central Texas, effective from Wednesday evening through Friday evening.
A weather pattern change is expected to begin on Wednesday as an upper-level low over the southwestern United States weakens the subtropical ridge axis over Texas and the western Gulf. Isolated to scattered showers and thunderstorms are forecast to develop during the daytime hours.
A Pacific cold front will move into the region on Thursday, spreading showers and thunderstorms over a larger portion of the area. Rainfall totals from Wednesday evening through Friday are expected to range between 2 and 4 inches, with isolated amounts up to 8 inches possible.
Impacts from the excessive rainfall could include life-threatening flooding within the watch area. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations, along with poor drainage and urban areas. Low-water crossings may also be flooded.
The affected counties include Atascosa, Bandera, Bastrop, Bexar, Blanco, Burnet, Caldwell, Comal, Dimmit, Edwards, Frio, Gillespie, Gonzales, Guadalupe, Hays, Kendall, Kerr, Kinney, Llano, Maverick, Medina, Real, Travis, Uvalde, Val Verde, Williamson, Wilson, and Zavala.
