What happens during a snow blizzard?

Blizzards. A blizzard is a severe snowstorm defined by the strength of the winds rather than the amount of snow it brings. With wind speeds at or above 35mph, blizzards create blowing snow conditions, where snow on the ground is picked up by the wind, causing reduced visibility and the accumulation of snowdrifts.

Interestingly, a blizzard does not technically have to involve active snowfall. If there is a large accumulation of snow on the ground already, sustained winds can blow that snow around and reduce visibility to blizzard-level conditions even when no snow is falling. This is called a “ground blizzard”.

What happens when a blizzard hits?

Blizzards bring about strong winds in the cold weather. These winds could blow up houses, damage property and cause power lines to collapse causing people to go without power and warmth. Communication systems could also go down or be interfered with, disrupting emergency communication.

What causes a Blizzard? In general, blizzards occur when a mass of warmer air collides with a mass of very cold air. The cold air mass cuts under the warm air mass, and as the warm moist air rises upwards it forms snow. The collision of the air masses also provides the atmospheric tension required for high wind speeds.
