Long before sunrise in Texas, a shallow spot of the Guadalupe River rose above the height of a two-story house in just five hours on Thursday, sending a rush of water through a region still weary from last summer's fatal flash floods.

A flash flood emergency is in effect for the Guadalupe River as water rises to dangerous levels in the Texas Hill Country, echoing the 2025 disaster.

Life-threatening flash flooding has hit southern Texas after days of torrential rain, leaving at least two people dead and hundreds of people rescued across the same region struck by last July’s catastrophic floods.

Emergency crews scrambled to rescue people from high water before sunrise Thursday.

Rising floodwaters and relentless rain have forced state officials into an escalated emergency response posture as a massive, moisture-rich storm system threatens to bring historic flooding to major portions of Texas.

Authorities urged people in other areas and the city of Boerne, outside San Antonio, to voluntarily evacuate rather than be marooned by high water.
