I don't have photoshop, unfortunatley. I have Paint.net and GIMP (freewares comparable to Photoshop) Using these tools I've quickly made a few false hurricanes.
This is what Hurricane Isabel would look like if it were in the Gulf.

This is what a category five direct hit on Puerto Rico would look like.

All I can really edit are satellite images, but I'll try to edit some other stuff, maybe a Las Vegas tornado.
But hey! This thread isn't about me. If there's anybody here who likes to photoshop weather events, but missed the photoshop contest, show me what you got!
