Rare snownado caught on camera at national park in Poland

Dec. 13 (UPI) -- A Polish man walking in a national park captured video of a rare winter weather phenomenon -- a snownado.

Michal Bielas posted a video to Facebook showing the unusual sight that greeted him Monday during a walk in Tatra National Park.

The video depicts a whirlwind rolling through the snow, creating what is known as a snownado or snow devil.

Experts said the rare phenomenon, which has only been caught on camera a small number of times previously, resulted from a strong gale of wind hitting the mountains and creating a rotating column of air.
