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

Although Kerr County was hit hardest by flooding, at least seven others have been confirmed dead in different parts of Texas. About 150 miles east of Camp Mystic, Travis County has confirmed at least six deaths, the county confirmed Sunday. Travis County includes the Texas capital city of Austin.

More than 40 people, including children, are still missing after a wall of flood waters surged after heavy rainfall.
