Reports of bizarre Wizard of Oz-like weather over Lake Michigan are touching down all over the Internet.

This past weekend, up to nine twisters were sighted over the lake. But they weren’t traditional tornadoes; they were waterspouts.

The funnels form when large, cool, and moist air masses move in over warmer surface water and winds abruptly change directions. The warming trend that researchers and locals are seeing around the Great Lakes could mean more waterspouts.
