Flash flooding in Texas Hill Country, triggered by intense thunderstorms, has resulted in at least 81 deaths, including at least 28 children. Camp Mystic, a girls' camp located on the Guadalupe River, confirmed at least 27 deaths among campers and counselors.

Catastrophic flooding killed 68 people in Kerr County, Texas, alone, where water washed through an all-girls summer camp, killing over two dozen people and sparking a desperate search for missing campers.

Hours before a massive wall of floodwater barreled down a river in the heart of Texas Hill Country before sunrise on Friday, forecasters with the National Weather Service warned people that dangerous conditions were brewing.
