SAN ANTONIO – Heavy rain that struck San Antonio Tuesday morning created a messy commute for drivers, triggered flood warnings and prompted high water rescues in a matter of hours.

KSAT crews were out on the roadways capturing videos and photos of flooded streets, swollen creeks and wrecks due to the showers, which dumped rain at the rate of nearly 3 inches per hour.

A Flash Flood Warning for western and northwestern Bexar County expired at noon, but flooding remains a concern in the area.

At least one person reportedly remains missing after high water swept three people away on the North Side. SAFD Spokesman Woody Woodward said the incident happened around 9:30 a.m. near Loop 410 and Vance Jackson Road.

If necessary, avoid areas and streets that are prone to flooding.

The National Weather Service has issued a flood warning for Leon Creek until Wednesday morning.

As of 9:30 a.m. Tuesday, the stage was 6.9 feet at the creek’s intersection with Interstate 35 on the Southwest Side. The flood gauge is 15 feet. The river is expected to rise above the flood stage this afternoon.

The forecasted flood levels will reach the highest levels since 1991.

There are also indications that nearly 9 inches of rain fell in the past 24 hours along Bandera Road at Leon Creek.

In some spots, more than 7 inches of rain has fallen Tuesday morning. (Copyright 2021 by KSAT - All rights reserved.)
