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.

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.

Thousands of commuters were trapped in the city, stranded on trains and subways. 30,000 men worked for an entire week at a cost of $6 million to remove the snow. 77 people died in eight north-eastern states.
