As a weather disturbance over the Gulf of Mexico makes its way into South Central Texas, meteorologists warned afternoon commuters to be on alert for flash flooding.

The system was expected to reach the Texas Gulf Coast early this morning, the National Weather Service said late Thursday.

NWS meteorologist Cory Van Pelt said San Antonio rain chances are forecast to increase throughout the day.

“If we get some heavy rain … areas around town could be flooding pretty quickly, especially before the afternoon commute,” Van Pelt said.
