South Texas flooding has stranded motorists and washed out highways after heavy rains dumped up to 16 inches in rural areas near the border with Mexico. Emergency crews have conducted at least two dozen rescues across the region, with officials shutting down parts of a highway near Uvalde, 80 miles west of San Antonio. The National Weather Service warns that more severe weather could bring dangerous flash flooding to already drenched counties.
Understanding the South Texas Flooding Pattern
Meteorologist Monte Oaks of the National Weather Service described the event as a "typical mid-summer tropical weather pattern" that occurs in Texas about once every five years. A stagnant low-pressure center is producing daily heavy rain chances, leading to compounding effects across the region. A flash flood warning remains in place for the San Antonio area, with torrential downpours expected through the afternoon.
Risk Areas and Rainfall Totals
Most areas of the San Antonio metro area are forecast to get between 2 and 4 inches of rain, while parts of central Texas, including the Hill Country and Kerrville, face a moderate risk of flash flooding. The National Weather Service has upgraded parts of the region to a rare level 4 "high" risk of excessive rainfall, indicating that flash flooding is likely. Rainfall totals between 3 and 7 inches are expected, with isolated higher totals of up to 15 inches possible.
| Location | Rainfall Forecast | Flood Risk Level |
|---|---|---|
| San Antonio Metro | 2–4 inches | Flash flood warning |
| Hill Country / Kerrville | 3–7 inches | Moderate to high |
| Areas West of San Antonio | Up to 15 inches | Level 4 high risk |
Safety Tips for Motorists During Flooding
If you encounter flooded roads, remember: turn around, don't drown. Just six inches of moving water can knock you down, and one foot of water can sweep away a vehicle. Avoid driving through standing water, and never ignore barricades or road closure signs. Keep an emergency kit in your car with essentials like water, non-perishable food, a flashlight, and a first-aid kit.
Key Takeaways for Flood Preparedness
- Monitor local weather alerts and avoid non-essential travel during flood warnings.
- Prepare a vehicle emergency kit with blankets, a phone charger, and a whistle.
- Know your evacuation route and have a plan for pets and family members.
- Never drive around barriers or through flooded intersections.
Comparing Flood Events: Past and Present
Two years ago, an area bordering the Guadalupe River experienced flash flooding that killed at least 139 people. The current system poses a similar threat, with the National Weather Service warning that storms overnight could dump more than a foot of additional rain, creating potentially catastrophic impacts. Intense rain rates and compounding effects from multiple rounds of storms will result in a dangerous flash flooding threat through Thursday.
