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.

Which is worse a snowstorm or a blizzard?

However, for a blizzard to be considered a "blizzard," winds must be sustained at 35 miles per hour; the snow must reduce visibility by a quarter mile or less; and the conditions must be expected to last for at least three hours. Therefore, blizzards generally tend to be more threatening than snowstorms.

What makes a blizzard different from a snowstorm?

Definition and etymology

In the United States, the National Weather Service defines a blizzard as a severe snow storm characterized by strong winds causing blowing snow that results in low visibilities. The difference between a blizzard and a snowstorm is the strength of the wind, not the amount of snow.
