Social media users are spreading false claims that flash floods in Texas that killed more than 100 people over the Fourth of July holiday weekend were caused by weather modification.

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.

Heavy rains fell quickly in the predawn hours of Friday in the Texas Hill Country, causing the Gaudalupe River to rise 26 feet in just 45 minutes.
