Torrential rains before dawn on Friday deluged the Guadalupe River, which burst its banks and killed dozens of people, leaving behind mangled piles of debris, trees and cars.

Even as authorities in Kerr County, Texas have repeatedly discouraged civilian volunteers from showing up to help in the search for victims of the region's historic flooding, many are, anyway.

The number of dead from the devastating floods across central Texas surpassed 100 as dozens of people remain missing. In Kerr County, at least 84 people died, including 28 children, according to officials.
