The disaster's total death toll reached two dozen by Friday night, with many people still missing after catastrophic flooding along the Guadalupe River.

The flooding brought the Guadalupe to its second-highest point in history, according to the National Weather Service, which urged people in the affected area to move to higher ground.

Camp Mystic, a Christian summer camp for girls ages 7 to 17, is located along the Guadalupe River in Hunt, Texas—a community now at the epicenter of a deadly flood emergency. At least six people have died in what Governor Greg Abbott called "devastating flooding" across the Hill Country and Concho Valley.
