San Antonio, TX – The National Weather Service is warning that parts of the Texas Hill Country remain under a rare High Risk for excessive rainfall Tuesday as torrential rain continues to produce life-threatening flash flooding, numerous water rescues, and flooded roadways.
According to the National Weather Service’s Weather Prediction Center (WPC), portions of Medina, Uvalde, and Bandera counties have already received 6 to 10 inches of rain, with localized totals approaching 12 inches. Forecasters say heavy rainfall will continue through at least midday Tuesday, increasing the risk of catastrophic flash flooding.
The High Risk designation is the Weather Prediction Center’s most serious excessive rainfall outlook and is issued on only about 4% of forecast days. Historically, these events account for roughly one-third of all flood-related fatalities and about 80% of flood-related damage nationwide, underscoring the severity of the current situation.
According to the National Weather Service, the extreme rainfall has already led to numerous flooded roads and multiple swiftwater rescues across the region. Emergency responders, including Texas Game Wardens and local agencies, have been assisting stranded motorists as rapidly rising water overtakes low-water crossings and rural roadways.
Outside the High Risk area, a Moderate Risk of excessive rainfall extends into portions of south-central Texas, while Slight and Marginal Risks cover additional areas of Texas and portions of the Gulf Coast, where localized flash flooding remains possible.
Officials continue to urge residents to avoid all flooded roadways and never drive through standing or moving water. Even a small amount of fast-moving water can sweep away a vehicle. Motorists are encouraged to follow the “Turn Around, Don’t Drown” message and monitor the latest forecasts and warnings from the National Weather Service and local emergency management officials as the event unfolds.
