A blizzard needs very cold air, warm air and moisture. When cold and warm air meet it makes clouds very heavy with moisture and the wind becomes very strong. This causes a blizzard.

Blizzards happen when in places that have very cold weather. They occur in the Arctic, Antarctica, Canada, United States and Europe.

My Mom remembers one storm that everyone called White Juan. When I was little we lived in Nova Scotia and during White Juan we lost our power, and outside our house there were big drifts of snow. My Mom and I had to stay in the house as there was no way for us to go anywhere. After the whole night with no power and the blizzard was finally over we walked to our neighbor's house because they had power, and stayed there for the rest of the day until we finally got our power back.
