I don't like having to repeat myself, so I'll just quote the reason....

I'm thinking these storms are due to cows farting and killing off the ozone which makes it easier for the ufos to enter our atmosphere. Everyone knows aliens like playing in the ocean with the sperm whales and once you get a sperm whale excited they spray man whale juice into the sky and it sticks to the clouds and then makes huricanes.

Isn't it obvious?
