At least six waterspouts were spotted in the Chesapeake Bay off the coast of Annapolis Friday morning.

Waterspouts, according to the National Oceanic and Atmospheric Administration, sometimes begin as tornadoes over land and then move over water, but can also form in severe thunderstorms over a body of water.

They can wreak havoc with high winds, hail, and dangerous lightning. They develop most often over warm, tropical ocean waters. They're spotted in the Florida Keys more than any other place in the world.

The Maryland Natural Resources Police posted on Twitter that one of its patrol boats got caught inside one.

A YouTube video of one of the spouts forming was also posted online by user Justin Berk. It was taken from inside a car that was traveling over the Chesapeake Bay Bridge. Watch it below.
