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.

There are reports some cloud seeding occurred a few days before the Texas flash flood. But it’s important to understand that cloud seeding has a relatively short-term effect in that a certain cloud is seeded and perhaps turns into one individual rain cloud or even a thunderstorm. The increased rainfall would not last for days.

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.
