KERRVILLE, Texas, July 5, (AP): At least 24 people were killed and a frantic search continued overnight for many others missing in the Texas Hill Country, including more than 20 from a girls camp, after a storm unleashed nearly a foot of rain and sent floodwaters spilling out of the Guadalupe River. The destructive force of the fast-rising waters just before dawn Friday washed out homes and swept away vehicles.

There were hundreds of rescues around Kerr County, including at least 167 by helicopter, authorities said. The total number of missing was not known but the sheriff said between 23 and 25 of them were girls who had been attending Camp Mystic, a Christian summer camp along the river. On social media, parents and families posted desperate pleas for information about loved ones caught in the flood zone.

"The camp was completely destroyed,” said Elinor Lester, 13, one of hundreds of campers at Camp Mystic. "A helicopter landed and started taking people away. It was really scary.” She said a raging storm woke up her cabin around 1:30 a.m. Friday, and when rescuers arrived, they tied a rope for the girls to hold as the children in her cabin walked across bridge with floodwaters whipping around the calves and knees.

The flooding in the middle of the night on the Fourth of July holiday caught many residents, campers and officials by surprise. Officials defended their preparations for severe weather and their response but said they had not expected such an intense downpour that was, in effect, the equivalent of months' worth of rain for the area.

One National Weather Service forecast this week had called for only between three and six inches (76 to 152 millimeters) of rain, said Nim Kidd, the chief of the Texas Division of Emergency Management. "It did not predict the amount of rain that we saw,” he said. At a news conference late Friday Kerr County Sheriff Larry Leitha said 24 people had been confirmed killed.
