A surge of 911 calls came in between 1 a.m. and 3 a.m. yesterday, according to Travis County Sheriff Sally Hernandez. But the roads were washed away so quickly that access to many of those who needed help was "completely cut off," she said.

Camp Mystic remains a major focus of concern. When the flash flood struck early on Friday, about 700 children were in residence, according to details provided Friday by Texas Lieutenant Governor Dan Patrick. As of Saturday afternoon, there were 27 missing campers from the camp, said Kerrville City Manager Dalton Rice.
