The San Antonio area is facing another day of potentially heavy rain, as parts of South Central Texas stare down the potential for flooding.
A Flash Flood Warning remains in effect until 8 a.m. Wednesday for Medina County, Uvalde County, southwestern Bandera County, and southeastern Real County, where life-threatening flooding is ongoing. The National Weather Service says widespread rainfall totals of 3 to 16 inches have already fallen over the past 24 hours, with additional downpours capable of producing 2 to 4 inches of rain per hour overnight.
Meantime, a High Risk for excessive rainfall outlook for parts of South-Central Texas has been issued. Warning of another round of torrential rain could trigger life-threatening flash flooding are expected to develop Wednesday morning.
Concern is increasing that areas already flooded by recent heavy rain—particularly along the U.S. Highway 90 corridor, the western Hill Country, southern Edwards Plateau and the Rio Grande region—could receive an additional 10 to 20 inches of rainfall where thunderstorms repeatedly move over the same locations tonight.
