The flash flood was the deadliest from inland flooding in the U.S. since Colorado’s Big Thompson Canyon flood on July 31, 1976, killed 144 people, said Bob Henson, a meteorologist with Yale Climate Connections. That flood surged through a narrow canyon packed with people on a holiday weekend marking Colorado’s centennial.

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