From staff reports
Del Rio and Val Verde County are included in a flood watch beginning Wednesday evening as an approaching cold front brings the potential for heavy rain and flash flooding over the next three days.
The National Weather Service issued the watch for 7 p.m. Wednesday, Sept. 30, through 7 p.m. Friday, Oct. 2. Neighboring Kinney, Edwards, Uvalde and Maverick counties are also included.
Forecasters expect widespread rainfall totals of 2 to 4 inches across the watch area, with isolated amounts reaching 8 inches. Those are regional projections, rather than a guarantee of how much rain will fall in Del Rio.
The weather service warns that excessive runoff could flood streets, low-water crossings, creeks, rivers and other low-lying areas. Life-threatening flooding is possible somewhere within the watch area.
Tuesday night will remain warm and humid, with increasing clouds and breezy conditions across the region. Moisture moving in from the Pacific and Gulf will help set the stage for the changing weather pattern.
Wednesday’s Del Rio forecast calls for thunderstorms, with a high near 96 degrees and an overnight low around 75. Additional thunderstorms are forecast Thursday, when the high is expected to reach about 90 degrees. Friday should be cooler, with a high near 85.
The National Weather Service expects the greatest regional threat for heavy rain and flash flooding from Wednesday night into Friday. A Pacific cold front moving through Thursday will help spread showers and thunderstorms across more of South-Central Texas before bringing cooler temperatures.
The flood watch means residents should prepare for possible flooding and monitor later forecasts for warnings. People living in flood-prone areas should be ready to act if conditions worsen. Drivers should avoid flooded roads and low-water crossings.
The City of Del Rio’s staff recommends residents use caution near roadways and crossings that have historically flooded during significant rain events, obey all barricades and road closure signs, and never drive through flooded roadways.
According to the city’s 2025 Master Watershed Study Addendum, areas of concern include:
- Johnson Street Bridge in the Lions Park area
- East Canal Street crossing
- East Academy Street crossing
- Railroad Avenue/East Bowie underpass
- Wildcat Drive
- Margaret Lane low-water crossing
- Alta Vista Drive low-water crossing
- Areas near Avenue U and Airport Boulevard
- Areas near Avenue U and 10th Street
- Areas near Avenue Q and 13th Street
City staff cautions that the list is not comprehensive. Localized flooding and ponding may occur anywhere heavy rainfall develops.
Residents are encouraged to monitor official City of Del Rio and National Weather Service updates throughout the week and follow the reminder: “Turn Around, Don’t Drown.”
