10 Blizzards!
How do blizzards form?
A blizzard is a long-lasting snowstorm with very strong winds and intense snowfall. You need three things to have a blizzard; cold air at the surface, lots of moisture (water in the air), and lift. Warm air must rise over cold air.
Blizzards can strand cars on highways for hours or even days. When you are traveling during the winter months, be sure to have first aid kits in the vehicle with you.

Snowflakes are made of ice crystals. Each snowflake is six-sided and made of as many as 200 ice crystals. Snowflakes form in clouds where the temperature is below freezing. The ice crystals form around tiny bits of dirt that has been carried up into the atmosphere by the wind. As the snow crystals grow, they become heavier and fall toward the ground.
