What meteorological criteria differentiate a Blizzard from a regular Winter Storm?
A blizzard requires sustained winds or frequent gusts of ≥56 km/h (35 mph) combined with falling or blowing snow reducing visibility to less than 400 meters for at least 3 continuous hours.
How does Lake-Effect Snow develop into extreme localized snow totals?
When frigid arctic air masses move over relatively warm open waters, moisture and heat evaporate into the lower atmosphere, condensing into intense snow bands that dump extreme snow amounts immediately downwind.
Essential emergency vehicle checklist for winter travel
Carry tire chains or winter tires, jumper cables, a compact snow shovel, high-calorie emergency rations, blankets, portable power banks, and ensure fuel tanks remain above half-full.
