What causes blizzards?

Blizzards are typically formed when cold, dry air from the Arctic region meets warm, moist air from the Gulf of Mexico. When these air masses collide, they create a strong pressure gradient, resulting in powerful winds. The moisture from the warm air then condenses and falls as snow, which is whipped up by the winds, leading to blizzard conditions.

Characteristics of blizzards

Blizzards are characterized by sustained winds of at least 35 miles per hour and visibility of less than a quarter mile due to blowing or falling snow. These conditions must last for at least 3 hours to be considered a blizzard.

Impacts of blizzards

Blizzards can have significant impacts on transportation, causing road closures and flight cancellations. They can also lead to power outages and disrupt daily life. Additionally, blizzards can pose health risks due to the extreme cold and limited visibility.

Staying safe during a blizzard

During a blizzard, it is important to stay indoors if possible and to have an emergency kit with essential supplies such as food, water, blankets, and flashlights. It is also crucial to dress warmly and limit time spent outside in the cold and windy conditions.
