3. What is a Blizzard? • A blizzard is a severe snow storm characterized by strong sustained winds of at least 56km/h 35(mph) and at least and lasting for a prolongedperiod of time—typically 3 hours or more. • For a blizzard to form, warm air must rise over cold air. There are two ways that this may happen. Winds pull cold air toward the equator from the poles and bring warm air toward the poles from the equator. When warm air and cold air are brought together, a front is formed and precipitation occurs. Warm air can also rise to form clouds and blizzard snows as it flows up a mountainside. • Return to table of contents

5. What places have been affected by a blizzard? • The Eastern Canadian Blizzard of March 1971 was a severe winter storm that struck portions of eastern Canada from March 3 to March 5, 1971. The storm was also nicknamed the "Storm of the Century" in Quebec The storm itself was responsible for the deaths of 17 people (30 province-wide) along with numerous other injuries directly and indirectly attributed to the blizzard. • The 1970-1971 winter season was the worst on record for many areas of eastern Ontario and southern Quebec in terms of all-time snowfall records. Ottawa had received up to 444 centimeters of snow (177.6 inches) that year and Montreal just over 380 centimeters (152 inches), records that were nearly broken during the 2007-08 season when Ottawa received 436 centimeters (174.4 inches) and Montreal 375 centimeters (150 inches). Quebec City also had their worst season in 1970-71 with 460 centimeters (184 inches) before it was broken in 2007-08 when just over 500 centimeters (200 inches) fell. • The Blizzard of 1977 was a deadly blizzard that hit Cleveland, Ohio, upstate New York and Southern Ontario from January 28 to February 1, 1977. Certain pre-existing weather conditions exacerbated the blizzard's effects. November, December and January average temperatures were much below normal. Lake Erie froze over by December 14; an ice-covered Lake Erie usually puts an end to lake-effect snow because the wind cannot pick up moisture from the lake's surface, convert the moisture to snow and then dump it when the winds reach shore. • Return to table of contents
