Portland, ME – Winter Weather Awareness Week kicks off Sunday, October 25, with an important question for Maine residents: What actually makes a winter storm a blizzard? The answer might surprise you, especially since heavy snowfall isn't necessarily required.
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.
That means even snow already on the ground can create blizzard conditions when powerful winds whip 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, while a Winter Storm Warning means dangerous conditions are expected or occurring.
A Blizzard Warning is issued when blizzard conditions are expected or underway. These conditions can make travel extremely dangerous, even for experienced winter drivers.
What Should You Have Ready Before a Blizzard? Maine residents should prepare emergency supplies before winter weather threatens their communities.
Recommended essentials include:
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 and emergency supplies. Snow removal: Shovels, ice melt, rock salt and traction materials. Never use outdoor grills or generators indoors because of carbon monoxide poisoning risks.
Why It Matters in Maine From Portland and Bangor to Augusta and communities across northern Maine, blizzards can quickly create impassable roads, power outages and dangerous conditions.
As Winter Weather Awareness Week continues through Saturday, October 31, residents are encouraged to review emergency plans, check supplies and follow official NWS forecasts.
Remember: A blizzard isn't defined by how much snow falls, but by the combination of wind, visibility and duration.
