More than 50 people have died, and search and rescue operations are still underway, following the devastating flash flooding that struck central Texas and caused the Guadalupe River to overflow on July 4.

A t least six people were killed and more than 20 children were missing from a girl’s summer camp after torrential rain caused widespread flooding in parts of central Texas. Several victims, both children and adults, were recovered in cars and in water, authorities said. The number of deaths is expected to rise.

The death toll from sudden 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.
