The record of frequent, often deadly floods in Central Texas goes back more than 200 years to July 1819, when floodwaters spilled into the major plazas of San Antonio. That city on the edge of the Hill Country was hit by major floods again in 1913, 1921, 1998 and 2025, to cite a few examples.

In what experts call "Flash Flood Alley," the terrain reacts quickly to rainfall steep slopes, rocky ground, and narrow riverbeds leave little time for warning.

Torrential rains triggered flash flooding in central Texas Friday, killing at least 95 people, including dozens of children.
