In the aftermath of deadly flash floods that swept through Texas Hill Country in July 2025, some people online suggested the storms may have been manufactured through a weather modification technique called cloud seeding.

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

This is false. It is not possible that cloud seeding generated the floods, according to experts, as the process can only produce limited precipitation using clouds that already exist.
