A RARE “snow tornado” has been spotted in the UK as the Met Office warns the country will be hit by a blizzard.
Crofter Michael Peterson was out feeding his sheep in Shetland when he saw the meteorological event following a hailstorm on Tuesday.
He told BBC Radio Shetland he was lucky to be in the “right place at the right time”.
Snow tornadoes, or snow devils, are “a very rare phenomenon,” according to the World Meteorological Organisation.
They are formed when snow is picked up by gusts of winds, creating a vortex.
It comes as the Met Office has issued an amber weather warning and told Brits to expect "strong winds bringing blizzard conditions".
