Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

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.

It took just 90 minutes for the river to rise more than 30 feet. A look at the historic flood levels now etched into Central Texas history.
