Parts of central Texas saw a month’s worth of rain in just a few hours overnight into Friday, prompting multiple flash flood emergencies. Follow for live updates on the rescue effort, including the search for more than 20 girls from a summer camp in the region.

According to Lt. Gov. Dan Patrick, at least 20 children are unaccounted for at Camp Mystic, an all-girls camp of 750 campers. He says this does not mean they've been lost. "They could be in a tree. They could be out of communication. We're praying for all those missing to be found alive," he said.
