Search and rescue missions continued into the early hours of Saturday after flooding in Central Texas killed at least 24 people and left others, including at least 20 girls attending a summer camp, unaccounted for. The missing girls were attending Camp Mystic on the banks of the Guadalupe River near the city of Kerrville when heavy rains caused the river to surge — rising from seven to 29 feet in one location. Flood warnings remained in place for some parts of the Austin-San Antonio region overnight, as Texans questioned why Kerr County did not have a flood warning system in place. Camp Mystic is a private Christian summer camp for girls, located 18 miles northwest of Kerrville on the banks of the Guadalupe River in Texas. It sits among cypress, oak and pecan trees and aims to provide young girls with a “wholesome Christian atmosphere” to develop self-esteem and personal qualities, according to the camp website . The U.S. Coast Guard “is punching through storms to evacuate Americans from central Texas,” Homeland Security Secretary Kristi L. Noem wrote on social media Friday evening. “We will fly throughout the night and as long as possible.” President Donald Trump described the flooding as “a terrible thing.” “It’s terrible. The floods? It’s shocking,” he told reporters Friday evening on Air Force One. “They don’t know the answer yet as to how many people but it looks like some young people have died.” When asked about federal aid, he said: “Oh yeah, we’ll take care of them. We’re working with the governor.” Heavy rain over Central Texas turned catastrophic in Friday’s early hours, as months of rainfall came down swiftly. Flooding rains in and around Kerr County had brought a widespread 10 to 15 total inches by Friday morning, in an area west of Austin and northwest of San Antonio, a region that typically averages 28 to 32 inches of rain in a year. Instead, four months of rainfall came down in four hours. This is an excerpt from a full story. The death toll from heavy flooding in Central Texas has risen to about 24, Kerr County Sheriff Larry L.
