Burlington, VT – Winter Weather Awareness Week begins Sunday, October 25, with an important question for Vermont residents: What actually makes a winter storm a blizzard? Surprisingly, heavy snowfall isn't always necessary for one to develop.
According to the National Weather Service NWS , a blizzard occurs when sustained winds or frequent gusts reach at least 35 mph, accompanied by falling or blowing snow that reduces visibility to one quarter mile or less for at least three hours.
Even snow already on the ground can create blizzard conditions when strong winds lift it into the air, producing dangerous whiteouts.
What's the Difference Between a Watch and a Warning? A Winter Storm Watch means significant winter weather is possible, giving residents time to prepare.
A Winter Storm Warning means dangerous winter conditions are expected or already occurring.
A Blizzard Warning is issued when blizzard conditions are expected or underway. Travel can become extremely dangerous as visibility drops and roads become difficult to navigate.
What Should Vermont Residents Have Ready? Before winter storms arrive, households should prepare emergency supplies, including:
Food and water: At least three days of nonperishable food and one gallon of water per person daily. Warmth: Extra blankets, sleeping bags, winter clothing and safe backup heating options. Emergency supplies: Flashlights, batteries, medications, first aid kits and charged power banks. Vehicles: A full tank of gas, blankets, jumper cables, an ice scraper and emergency supplies. Snow removal: Shovels, ice melt, rock salt and traction materials. Never operate generators, outdoor grills or other fuel burning outdoor equipment inside homes or garages because of carbon monoxide poisoning risks.
Why It Matters Across Vermont From Burlington and Chittenden County to Montpelier, Rutland and the Northeast Kingdom, winter storms can create hazardous travel conditions, particularly along mountain passes and rural highways.
Blowing snow can sharply reduce visibility, while power outages and blocked roads may delay emergency assistance.
As Winter Weather Awareness Week continues through Saturday, October 31, Vermont residents are encouraged to review emergency plans, check supplies and monitor official NWS forecasts.
Remember: A blizzard is defined by wind, visibility and duration — not snowfall totals.
