More than 160 people are still believed to be missing in Texas days after flash floods killed over 100 people during the July Fourth weekend, the state’s governor said Tuesday.

Gov. Greg Abbott says 161 people remain missing after catastrophic Central Texas flooding, as the death toll climbs to 109 and search efforts intensify.

Four days have passed since anyone was found alive in the aftermath of the floods in Kerr County, Texas, officials said Tuesday.

Emergency responders kept hope alive as they combed through fallen trees and other debris that littered the hard-hit central Texas communities on the fifth day after devastating floods killed more than 100.

Flash flooding in Texas Hill Country has triggered one of the largest rescue operations in the state’s history

The stunning flood that killed more than two dozen campers and counselors along a river at Camp Mystic in the Texas Hill Country was the result of extraordinary rain and walls of water. Nonetheless, experts agree that information about how a camp plans for emergencies is just as important as the lunch menu and the times to go swimming.
