At least 24 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

The heavy rains overnight Thursday and into Friday hit a region of Texas called Hill Country. The hilly terrain gives the water nowhere to go, overflowing rivers and other bodies of water, said Scott Kleebauer, a meteorologist with the National Weather Service.
