RAIN ENDING: Expect a break Wednesday & Thursday
FORECAST Heavy storms produced areas of 6+ inches of rain west of San Antonio and in the Hill Country. This is causing the Frio River to rise and flood.
We have the potential for localized downpours through the night, so use caution on roads. You can watch LIVE RADAR in video at the top of this page.
DRIER BY MIDWEEK
Drier conditions take over starting Wednesday. A rain-free forecast should hold for Wednesday and Thursday, but we’re watching an area of upper-level energy that could generate storms Friday. It’s currently a cluster of unorganized storms near Florida and has a small chance of developing into an organized tropical system. As of now, odds are low (30%) for development.
Potential tropical development at 30% over the next seven days. (Copyright 2024 by KSAT - All rights reserved.)
