Winter Weather Awareness Week November 18-22

Sunday, November 17th, 2024 -- 7:18 AM

Wintertime poses a wide range of threats to residents of the Midwest. November 18 to 22 is Winter Weather Awareness Week in Wisconsin. Whether it be exposure to the cold, vehicle accidents caused by slick roads, or fires resulting from the improper use of heaters, hundreds of people are injured or killed each year as a direct result of winter weather. 

Winter storms range from a moderate snow over a few hours to a massive blizzard with blinding, wind-driven snow that lasts for several days. Some winter storms are large enough to affect several states while others affect only a single community.

High winds, freezing rain or sleet, heavy snowfall, and dangerously cold temperatures are the main hazards associated with winter storms. Impassable snow drifts can maroon people at home without utilities or other services for days after an event. Heavy snowfall and blizzards easily trap motorists in their vehicles and make walking to find help a deadly effort. Bitter cold temperatures and wind chills during and after a winter storm can lead to hypothermia and kill anyone caught outside for too long. The aftermath of a winter storm can impact a community or region for days, weeks or even months, incurring steep economic costs.

Extremely cold air comes every winter in at least part of the country and affects millions of people across the United States. Extreme cold can come with (wind chill) or without wind - cold is cold and can quickly become life threatening if the proper precautions aren't followed.

New for the 2024-2025 winter, the NWS will no longer issue Wind Chill Warnings or Wind Chill Advisories. Instead, Extreme Cold Warnings and Cold Weather Advisories will be issued, which are based on apparent temperature. Apparent temperature is the ambient air temperature when there is no wind (calm conditions) or the wind chill when there is wind. These changes are part of the NWS Hazard Simplification Program.

Terms to Know:

• Blizzard: Blowing and/or falling snow with winds of at least 35 mph, reducing visibilities to a quarter of a mile or less for at least three hours. Winds lofting the current snow pack and reducing visibilities without any falling snow is called a ground blizzard.
• Freezing Rain: Caused by rain falling on surfaces with a temperature below freezing. The rain freezes upon contact with the ground. Large build-ups of ice can down trees and power lines and coat roads.
• Sleet: Rain/melted snow that has begun refreezing when it reaches the ground. Sleet tends to be softer than hail and is easily compacted. Sleet can make roads slippery very quickly.
• Wind Chill: The apparent temperature the body feels when wind is factored into the equation.
