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.

At least 56 adults and 30 children have been killed in Kerr County, Sheriff Larry Leitha said at a press conference, with more than two dozen victims yet to be identified. Local officials have faced angry questions about whether they could have warned people of dangerous flash floods in Texas Hill Country sooner.

Six counties reported deaths from multiple severe flood events since Friday, July 4. Also, Kerrville officials reported that a privately owned drone collided with a helicopter conducting search and rescue operations.
