Texas Hill Country Faces Flash Flood Threat
23 May
Summary
- Flash flood warning issued for the region around Medina Lake through Monday.
- Rainfall has caused water levels to rise in local creeks and rivers.
- Life-threatening flooding is possible over the Memorial Day weekend.
Severe weather this week has led to rising water levels in Texas Hill Country creeks and rivers. Consequently, local water officials have issued a flash flood warning that will remain in effect through Monday, May 25, 2026, for residents and Memorial Day weekend visitors.
Rainfall, ranging from less than a half-inch to just over 2 inches, was recorded across monitoring locations, affecting the Medina and Sabinal rivers. Even Medina Lake, which previously reached "dead pool" status, observed a slight rise in water levels on Wednesday, May 20, 2026. Despite this increase, the lake remains significantly below normal levels, currently at 3.9% capacity as of Friday, May 22, 2026.
The National Weather Service (NWS) has issued a flood watch for the region, warning of possible "life-threatening" flooding over the holiday weekend. Anticipated rainfall totals of 2 to 4 inches are expected, with isolated areas potentially receiving up to 6 inches. The NWS stresses that rivers, creeks, and low-water crossings could flood rapidly during heavy downpours.
Areas under the flood watch include San Antonio, the I-35 corridor, Kerrville, Fredericksburg, Boerne, and Llano. The Bandera County River Authority & Groundwater District and the NWS urge everyone to enable mobile emergency alerts in preparation for potential flash flooding or severe weather emergencies.
