The flooding poses a significant risk to residents in Uvalde County, Boerne, and other areas west of San Antonio. Rising rivers and creeks, including the Leona River, have led to mandatory evacuations and stranded motorists. High-water rescues have been conducted, with at least 25 rescues reported in Uvalde County alone. The Cibolo Creek in Boerne has risen 19 feet above its usual level, creating life-threatening conditions. The hilly terrain in the region increases the vulnerability to flash flooding, and further rainfall could exacerbate the situation.
