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.

Despite conspiracy theories, there's no way that cloud seeding operations days before the storm could have influenced the floods, scientists say.

Cloud seeding couldn’t have caused the floods that killed more than 100 people, experts say. But rumormongers suggested a link to one company’s work.
