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.

Survivors have described the floods along the Guadalupe River as a “pitch black wall of death” and said they received no emergency warnings.

Five campers and one counselor from Camp Mystic remain unaccounted for, officials say amid mounting questions over who was responsible for monitoring the weather.
