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.
