Flood Warning Issued for South Texas Rivers as Rising Waters Threaten Communities and Power Outages Impact Dimmit County
Heavy rainfall across South Texas has prompted multiple Flood Warnings as rivers continue to rise, creating dangerous conditions for residents in Frio, La Salle, and Dimmit counties. Emergency officials are urging the public to avoid flooded roadways, remain alert for rapidly changing water levels, and prepare for additional impacts as river flooding continues.
Rivers Under Flood Warning
Frio River at Tilden
The Frio River at Tilden remains under a Flood Warning as elevated water levels continue to threaten nearby low-lying areas. Roads near the river, agricultural land, and rural communities could experience flooding. Residents living near the river should closely monitor official forecasts and be prepared to move to higher ground if conditions worsen.
Frio River Near Derby
The Frio River near Derby is also experiencing dangerous flooding. Rising water levels may impact river crossings, parks, ranches, and nearby infrastructure. Motorists should never attempt to drive through flooded roadways, as water depth and current can change rapidly.
Nueces River at Cotulla
Flooding continues along the Nueces River at Cotulla, where water levels remain above normal. Floodwaters may affect nearby roads, agricultural operations, and recreational areas. Residents should expect possible road closures and delays while emergency crews monitor conditions.
Nueces River Near Asherton
The Nueces River near Asherton remains under Flood Warning as runoff from recent rainfall continues to move downstream. Additional rises remain possible depending on upstream rainfall, increasing the risk for flooding in flood-prone locations.
Dimmit County Experiencing Power Outages
Flooding has also contributed to power outages across portions of Dimmit County. Saturated ground, damaged utility equipment, and severe weather have disrupted electrical service for some residents.
If you experience a power outage:
- Keep refrigerators and freezers closed to preserve food.
- Use flashlights instead of candles to reduce fire hazards.
- Never operate generators indoors or in enclosed spaces.
- Report outages directly to your electric utility.
- Charge mobile devices whenever power is available.
Safety Tips During River Flooding
Flooding remains one of the deadliest weather hazards in the United States. Residents across South Texas should take the following precautions:
- Never drive through flooded roads. Turn Around, Don’t Drown.
- Stay away from fast-moving rivers and floodwaters.
- Monitor local emergency alerts and National Weather Service updates.
- Prepare emergency supplies, including medications, water, and important documents.
- Move livestock and equipment away from flood-prone areas if it is safe to do so.
Forecast Outlook
River levels across the Frio and Nueces River basins will continue to be monitored closely over the coming days. Additional rainfall could prolong flooding or cause renewed rises along area rivers. Residents throughout South Texas should remain weather-aware and continue following updates from local emergency management officials.
Early preparation and staying informed remain the best defenses against rapidly changing flood conditions.
