About Blizzard
A blizzard is a severe snowstorm characterized by strong sustained winds of at least 56 km/h (35 mph) and lasting for a prolonged period of time — typically three hours or more. A severe blizzard has winds over 72 km/h (45 mph), near zero visibility, and temperatures of −12 °C (10 °F) or lower. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds.
