Kerr County death toll now 59, officials say, including 21 children

Dozens of people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding.

Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.

"So many people have been swept up into an extraordinary catastrophe," Abbott said, asking for prayers for residents.

Children are among the dead, and about 23 campers from a summer camp in the area, Camp Mystic, were unaccounted for, Lt. Gov. Dan Patrick said at an earlier news conference.
