A bizarre cloud was seen spinning in the sky during a thunderstorm in Turku, southern Finland on May 17.

The funnel cloud is seen rotating as it stretches across the skyline with a stormy backdrop.

"On the edge of the thunderstorm, the cloud starts to spin and moves upwards towards a bigger cloud. Rotation lasted for a few minutes before it stopped and the cloud disappeared. The cloud wasn't touching the ground. The video is filmed in Finland, where these kinds of things are rare," the filmer told Newsflare.
