Flash floods that swept through Texas over the Fourth of July weekend have left more than 100 people dead and dozens of others missing.

Fifty-nine people are dead as a result of the flooding and torrential rains in Kerr County, Texas, Sheriff Larry Leitha said during a Sunday-morning press conference. That tally includes 38 adults and 21 children, Leitha said.

Across Central Texas, there have been more than 90 confirmed deaths from the weekend flooding: six people were reported dead in Kendall County, seven in Travis County, four in Williamson County and four in Burnet County, officials said Monday. At least 15 people are still missing in the Austin area.
