Explanation

The difference between a blizzard and a snowstorm is the strength of the wind, not the amount of snow. To be a blizzard, a snowstorm must have sustained winds or frequent gusts that are greater than or equal to 56 km/h (35 mph) with blowing or drifting snow, which reduces visibility to 400 meters or a quarter mile or less and must last for a prolonged period of time, typically three hours or more.
