The heavy rain that turned a river in Texas into a raging wall of water was fueled by unique atmospheric conditions, according to meteorologists and climate scientists.

Flash floods in Texas have killed at more than 80 people, many of them children.

Flash floods swept through Texas over the Fourth of July weekend, leaving more than 90 people dead. Dozens remain missing.

At least 43 people died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, according to officials. Children are among the dead, said Lt. Gov. Dan Patrick, who has taken on the duties of acting governor.
