San Antonio, TX – Heavy rainfall could create dangerous flash flooding conditions across portions of South Central Texas Thursday, Oct. 29, through Friday morning, Oct. 30, with some communities potentially receiving as much as 6 inches of rain.
According to the National Weather Service Austin San Antonio office, rounds of showers and thunderstorms are expected to affect western portions of South Central Texas, particularly the Edwards Plateau and Rio Grande corridor.
Forecasters indicate that widespread rainfall totals of 2 to 4 inches are possible within the most affected areas, with isolated pockets receiving up to 6 inches.
The greatest concern for flash flooding extends along a north to south corridor that includes portions of the southern Edwards Plateau and Rio Grande Plains.
Communities near Del Rio, Rocksprings, Sonora and Eagle Pass are among those that could experience heavier rainfall.
The National Weather Service's Thursday morning forecast shows particularly high precipitation probabilities near Del Rio and Rocksprings, reaching 90% and 80%, respectively.
Rain chances are lower farther east, including around San Antonio and Austin, where forecast rainfall totals are substantially lighter.
Thursday will also bring cloudy skies and temperatures generally ranging from the upper 60s to lower 80s, with southeast to east winds of 5 to 15 mph.
Rain chances continue into Friday across the western two thirds of South Central Texas before gradually decreasing.
Drier conditions are expected to return Saturday night into Sunday, Nov. 1, providing a break from the unsettled weather.
However, another cold front arriving late Monday into Tuesday could bring renewed rain chances to the region.
Residents in flood prone areas should monitor weather alerts, avoid driving across flooded roadways and remain aware of rapidly changing conditions near low water crossings.
Rainfall amounts and locations may change as additional thunderstorms develop.
