(Reuters) -A frantic search continued on Saturday for about two dozen people still missing from a century-old Christian girls' camp in central Texas after flash floods in the area killed at least 24 at the start of the U.S. Independence Day weekend and prompted the rescue of hundreds of others. In a break for rescue crews, authorities said flood waters on Saturday were receding in the area around the Guadalupe River, about 85 miles (137 km) northwest of San Antonio, where at least 237 people were rescued, with more than 100 by helicopters. The U.S. National Weather Service said that the flash flood emergency has largely ended for parts of Kerr County in south-central Texas Hill Country, about 65 miles (105 km) northwest of San Antonio, following thunderstorms that dumped as much as a foot of rain early on Friday.
