At least 82 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.

Flash floods in Texas killed at least 82 people over the Fourth of July holiday weekend and left others still missing, including girls attending a summer camp.

A flood watch issued for parts of Texas has been extended into Monday evening, leaving thousands at risk. The National Weather Service San Angelo office said on Sunday that flash flooding caused by excessive rainfall could occur in Heartland, portions of Concho Valley, Edwards Plateau and Hill Country until 7:00 p.m. on Monday.
