About two dozen people were still missing. Many more people could still be unaccounted for, officials warned, noting that visitors to the area for the July 4th weekend make it difficult to assess an exact number.

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.

Emergency responders continue to search for missing people and local police said efforts have been slowed by "sightseers who are making things worse."
