What are they? Blizzards are severe winter storms that involve very low temperatures(-20 to –40°C), and strong winds. The winds usually exceed 35mph. Blizzards are a type of storm that occurs when warm and cold air masses intermix and attempt to equalize their temperatures.

How are they formed? Blizzards form when warm air moving north collides with a cold air mass that has been pushed down from the Arctic. During a blizzard it doesn’t actually have to snow. The winds will stir up the snow on the ground and we’ll end up with a blizzard.

Where do they happen? Blizzard's mostly happen in the dangerous cold mass that produce blizzards They usually come from the North Pole,South Pole in the coast of the USA, UK, Columbia, Canada, and rocky mountains although Blizzards are actually not as common in the USA as in some parts of the world but, they say the blizzards in the USA are more dangerous because the people are less prepared.

Risks Blizzards have a high potential for destruction. Accumulation of snow on tree branches cause many trees to break and fall on cars, houses, and block streets. Highways and airways experience major delays because of the large amounts of snow and lack of visibility. People are forced to stay home from school and work, also their daily activities are limited.
