Quick Summary

A blizzard is a severe weather condition characterized by low temperatures, strong winds, and significant snowfall. The U.S. National Weather Service defines a blizzard as a storm with winds exceeding 56 km/h (35 mph) for at least three hours, reducing visibility to 0.4 km (0.25 mile) or less. A severe blizzard involves winds over 72 km/h (45 mph), near-zero visibility, and temperatures of -12 °C (10 °F) or lower. A ground blizzard occurs when snow is blowing and drifting without falling. The term originated in the central United States, often associated with winter low-pressure systems. The Great Blizzard of 1888, which struck the U.S. Atlantic coast, is considered one of the worst in American history, causing extensive damage and fatalities.123
