Blizzard Defined

"A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer.

(1) Sustained wind or frequent gusts to 35 miles an hour or greater;


(2) considerable falling and/or blowing snow (i.e., reducing visibility frequently to less than 1/4 mile).

Although there is no set temperature requirement for blizzard conditions, the life-threatening nature of the low temperatures in combination with the other hazardous conditions of wind, snow, and poor visibility increases dramatically when the temperature falls below 20°F. "


Let/s be careful out there this winter. Heavy snowfall does not a blizzard make. Blizzards are meso-beta scale (20 - 200 km) severe winter wx wind storms where visibility is restricted for at least three (3) hours.
