NOAA – Hays County Flash Flood Watch: Possible Heavy Rainfall Across Hays County Tonight Into Early Sunday Afternoon

Heavy rainfall amounts of 2 to 4 inches received this afternoon across the Austin metro area and adjacent areas of the eastern Hill Country have resulted in saturated soil conditions and extra run-off flowing into area creeks and streams.

Another 1 to 2 inches of rain could fall locally within the watch area late this afternoon, with slightly less rainfall expected during the evening hours. A second round of heavy rains are expected to return late tonight into midday Sunday with an additional 1 to 3 inches of rainfall expected.

These additional rains will further add to the threat of flash flooding. The cumulative heavy rainfall amounts will likely lead to some significant rises in some of the larger stream basins by late Sunday morning.

 FLASH FLOOD WATCH IN EFFECT THROUGH SUNDAY AFTERNOON…

The National Weather Service in Austin/San Antonio has issued a Flash Flood Watch for a portion of south central Texas, including the following areas, Bastrop, Blanco, Caldwell,

Hays, Lee, Travis, and Williamson.

• Through Sunday afternoon

• Heavy rains that occurred today will combine with an additional to 3 inches of rain expected tonight into Sunday to lead to a flash flood threat.
