At least 81 people are dead and at least 41 more are missing after devastating flash floods slammed Texas Hill Country, with water rescues taking place along the Guadalupe River, which rose rapidly early Friday morning to the height of a two-story building.

The death toll now stands at 70 in the wake of torrential rains and the resulting flooding in Texas. By far the greatest number of fatalities occurred in Kerr County, where 59 people are believed to be dead, according to officials, including 21 children.
