 The hypothesis was that the silver iodide would cause supercooled water in the storm to freeze , disrupting the inner structure of the hurricane . This led to the seeding of several Atlantic hurricanes . However , it was later shown that this hypothesis was incorrect . It was determined most hurricanes do not contain enough supercooled water for cloud seeding to be effective . Additionally , researchers found that unseeded hurricanes often undergo the same structural changes that were expected from seeded hurricanes . This finding called Stormfury 's successes into question , as the changes reported now had a natural explanation .
