Flash Flood Warning in Effect for Parts of South Central Texas
Residents across Northwestern Bexar County, West Central Comal County, and Southeastern Kendall County should take immediate precautions as a Flash Flood Warning remains in effect. Heavy rainfall continues to create dangerous flooding conditions capable of producing rapidly rising water across roads, neighborhoods, and waterways.
A broader Flood Watch also remains in effect for much of South Central Texas, where additional rounds of heavy rain may lead to life-threatening flash flooding.
Flood Watch Includes the Following Texas Counties
The Flood Watch covers:
- Bandera
- Bexar
- Blanco
- Burnet
- Comal
- Dimmit
- Edwards
- Frio
- Gillespie
- Hays
- Kendall
- Kerr
- Kinney
- Llano
- Maverick
- Medina
- Real
- Travis
- Uvalde
- Val Verde
- Williamson

Forecasters warn there is potential for life-threatening flooding somewhere within the watch area as repeated heavy rainfall develops across the region.
Greatest Flood Threat West of San Antonio
The highest risk for dangerous flooding is expected along the U.S. Highway 90 corridor west of San Antonio, including portions of:
- Southern Edwards Plateau
- Rio Grande region
Meteorologists indicate considerable to locally catastrophic flash flooding is possible in these locations where intense rainfall may overwhelm drainage systems in a short period of time.
Expected Flood Impacts
Heavy rainfall may produce numerous hazardous conditions, including:
- Life-threatening flash flooding
- Overflowing creeks and streams
- Rivers rising rapidly above their banks
- Flooding in low-lying and flood-prone areas
- Flooded neighborhoods
- Extensive street flooding
- Urban flooding due to poor drainage
- Flooded low-water crossings
- Dangerous travel conditions
- Washed-out roadways in isolated locations
Even areas that are not typically prone to flooding could experience rapidly rising water if multiple rounds of thunderstorms move across the same locations.
Flood Safety Tips
If you are in the warning or watch area:
- Never drive through flooded roadways.
- Turn Around, Don’t Drown® if water covers the road.
- Move to higher ground if flooding develops.
- Avoid camping or recreating near rivers, creeks, and streams.
- Monitor local weather alerts throughout the day and overnight.
- Have multiple ways to receive emergency warnings.
Remember that only a small amount of moving water can sweep away a vehicle, and floodwaters often hide washed-out pavement beneath the surface.
Stay Weather Aware
Additional rounds of heavy rain remain possible across South Central Texas, meaning flash flooding could develop rapidly with little warning. Residents should closely monitor forecasts and be prepared to act immediately if additional Flash Flood Warnings are issued.
Flash floods are among the deadliest weather hazards in Texas. Staying informed and avoiding flooded roadways can save lives.
