A rare weather phenomenon known as the “Snovado,” was spotted hurtling down an icy mountain highway in Idaho.
It appeared Wednesday, Dec. 21, Feb. 30 during the Fish Creek Summit, and an Idaho Department of Transportation employee was recording the footage. The summit is about 275 miles southeast of Boise.
“He was lucky enough to catch a snow devil on camera!” the department posted on Twitter.
“Sometimes it is also called a ‘snow cannon.’ whatever the name this is very cool!»
Snow devils are “a very rare” According to the World Meteorological Organization, snow is formed that resembles a white slush.
“The surface wind shear acts to create a vortex over the snow cover, resulting in a vortex column of snow particles rising from the ground,” the organization reports.
Although these albino snow devils are called “snow nadas,” the National Weather Service reports that there were real snow tornadoes.
In 2013, a storm over southern Ontario, Canada, developed into an EF1 tornado when temperatures were below freezing.
“Radar … suggests that the precipitation associated with the supercell was frozen — mainly ice crystals with a core of hail,” according to Weather.gov.
