Blizzards are well known for their high winds, low temperatures and the huge amounts of snow that are left after. They are known to leave a lot of damage, power outages icy roads etc. ﻿Blizzards are caused by Very clod air from the north collides with warm air from the south, creating a low pressure zone. With the low pressure very high winds will form. The warm air then rises above the cold air causes a huge cloud, which then leads to heavy snow fall but snow will only fall if the temperature from the bottom of the cloud to the ground is below 40 degrees.(3) High winds can also cause snow drifts that can be up to fifty feet deep.

Blizzards are extremely dangerous and scary storms. In order to stay safe during a blizzard it would be wise to do all of the following things.

You can however go outside when there is a low wind chill, but it is crucial to be cautious while doing so,(1). The wind chill factor is the coldness one feels because of the mix of a cool temperature, and wind, (1). Power outages are very likely as result of the harsh winds and heavy snow of a blizzard, (1). Because of these possible power outages, it is wise to have a generator, and flashlights with fresh batteries on hand to provide you a source light. To help you stay warm, it is a good idea to keep candles, blankets, and firewood on hand.
