San Antonio Area Flood Warning Drives Flooding Road Closures Until 10 a.m.

A Flood Warning is in effect for Bexar, Medina, Comal and Guadalupe counties until 10 a.m. Friday, and flooding road closures are possible as storms move through the San Antonio area during the morning commute. School districts and universities were monitoring conditions at 6:30 a.m. Friday as inclement weather spread across the region.

Bexar County and Nearby Counties

The warning covers 4 counties, with locally heavy rainfall likely to cause street flooding. The main concern is low-lying and poor-drainage areas, including construction zones.

Rounds of storms could bring heavy rain through Friday evening. Much of the rainfall is expected to be beneficial, but the same system can still produce street flooding where water has nowhere to go.

Friday Morning Commute

The timing puts the heaviest concern squarely on the Friday morning commute. Drivers in Bexar, Medina, Comal and Guadalupe counties may encounter water over roads before the warning expires at 10 a.m.

At least one area district has announced that classes will be canceled. The early monitoring at 6:30 a.m. Friday shows school systems and universities were already tracking whether conditions would change before students and staff left for the day.

Construction Zones

Construction zones are among the areas identified as most exposed to street flooding. That leaves some roads more vulnerable than others even if rainfall is only locally heavy, which is why short bursts of rain can create travel problems quickly.

For readers heading out Friday morning, the practical step is simple: check routes before leaving and expect delays in the four-county area until the warning ends at 10 a.m.
