MORNING UPDATE:
The heavy rainfall west of San Antonio has again cranked up this morning. Flood warnings have been posted for large portions of the Highway 90 area and into the Hill Country. Another round of heavy rain looks poised to lift north into the area later this morning. We are monitoring the situation, as well as river levels. So far, rivers, while moving at fast rates, have only risen to minor flood stage. This could change rapidly, so those along rivers and creeks need to remain vigilant.
6:24 AM Update:
Rain coverage is increasing across the viewing area, with the heaviest activity over Frio, Medina, and Uvalde Counties. Severe weather is also developing amongst this activity, with strong winds and rotation possible. Expect to see more activity developing around San Antonio this morning.
A HIGH risk of flash flooding continues today. (Copyright 2026 by KSAT – All rights reserved.)
