School districts and universities across the San Antonio area were monitoring conditions Friday morning as rounds of storms threatened heavy rain, and at least one district had already canceled classes by 6:30 a.m. Friday. A Flood Warning was in effect for Bexar, Medina, Comal and Guadalupe counties until 10 a.m. Friday, covering the morning commute as flooding road closures remained a concern.
The weather was expected to stay active through Friday evening, with locally heavy rainfall likely enough to cause street flooding, especially in low-lying and poor-drainage areas. Construction zones were also flagged as a concern, and gusty winds and localized hail were possible. Much of the rain was expected to be beneficial, but the risk of sudden flooding meant schools and universities were keeping a close watch on conditions throughout the day.
That mix of useful rain and short-lived danger is why the warning mattered Friday morning: even when the broader system helps, the heaviest bursts can still turn ordinary streets into problem spots fast. For anyone driving through Bexar County and the surrounding counties, the key issue was not the total rainfall, but where it fell hardest and whether it hit roads already vulnerable to standing water.
The next stretch of concern ran through Friday evening, when additional storms could keep water on the roads and force more interruptions in the San Antonio area. By then, the immediate question was whether the morning warning would stay limited to nuisance flooding or start turning into more widespread flooding road closures.
