Rescuers continue to search for an estimated 20 girls who were at Camp Mystic in Hunt, Texas when deadly floods from the Guadalupe River swept through the camp.

Heavy rainfall has overwhelmed multiple low water crossings and areas along the Guadalupe River, local authorities reported.

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.
