What is a Blizzard?

A blizzard is a severe snowstorm with sustained winds of at least 35 miles per hour (56 kilometers per hour) and visibility of less than a quarter mile (0.4 kilometers) for at least 3 hours. These conditions can create whiteout conditions, making it difficult to see and navigate.

Formation of Blizzards

Blizzards typically occur when cold, dry air from the north meets warm, moist air from the south. This collision of air masses can lead to the rapid development of a storm, accompanied by heavy snowfall and strong winds.

Impact of Blizzards

Blizzards can have serious consequences, including transportation disruptions, power outages, and dangerous conditions for both humans and animals. The combination of heavy snow, high winds, and low visibility can make travel treacherous and lead to accidents and injuries.

Staying Safe During a Blizzard

It's important to be prepared for blizzard conditions. This may include staying indoors, stocking up on supplies, and having emergency plans in place. Additionally, it's crucial to dress warmly and avoid unnecessary travel during a blizzard.
