The death toll from historic flooding in Texas' Hill Country rose to 104 Monday as Camp Mystic girls summer camp confirmed 27 campers and counselors died. Several other people remain missing.

Dozens of people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

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.
