Before hundreds of first responders and volunteers from around the country came to help, it was the local residents of Texas Hill Country who faced down a deadly wall of water along the Gaudalope River and witnessed terrifying scenes.

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.

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.
