Thunderstorms cause flash flooding in Hays County

Thunderstorms dump several inches rain on San Marcos


After a round of strong and severe thunderstorms moved through Central Texas late Tuesday morning and early afternoon, the Austin metro area is preparing for another round of thunderstorms.


Roads are closed in and around San Marcos after thunderstorms dumped several inches of rain Tuesday, eliciting flash flood warnings from the National Weather Service.

San Marcos CISD said on its website that they are sheltering in place. Parents are encouraged to avoid flooding streets until further notice.

Texas State University suspended classes at its San Marcos campus until 5 p.m. Tuesday. Round Rock's campus is still operating on normal schedule. Austin Community College said ACC San Marcos Goodnight Center will be closed for the remainder of April 11.

The City of San Marcos is also tweeting out road closures as the waters recede. Caldwell County Office of Emergency Management is also tweeting road closures.

National Weather Service had the following rain totals at sites in and around Hays County:

A second round of thunderstorms began moving into the Hill Country around the lunch hour, and have since begun moving into the Austin metro area. None of the storms meet the criteria to be severe (58+ mph wind gusts or quarter-size hail), but these storms will bring lightning and heavy rain.
