At least 24 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Vehicles, campers and homes were swept away along the Guadalupe River in Kerr County, Texas, as storms caused a flash flood emergency in the area. A flash flood emergency was also declared in San Angelo further north of Texas Hill Country.

The death toll from devastating floods in the Texas Hill Country rose to 24 Friday night, officials said, as the search for more than 20 people missing from a girls summer camp continued through the night.
