Emergency responders continued to search for missing individuals including at least 10 girls who were attending a summer camp on the banks of the Guadalupe River.

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

With more rain on the way, the risk of life-threatening flooding was still high in central Texas on Monday even as crews search urgently for the missing following a holiday weekend deluge that killed at least 82 people, including children at summer camps. Officials said the death toll was sure to rise.
