December 9, 1977 brought a massive snowstorm accompanied by powerful winds and blindly low visibility to southern Ontario as an intense storm system moved across the Ohio Valley in the United States. The total snowfall for the storm averaged about a foot in most places, but some areas received much more, as enhanced snowfall was created by additional lake effect snowfall combined with the large-scale storm system. The blizzard was made unique by the sustained winds, gusting up to 70 mph which picked up the snowdrifts already accumulated earlier in the season and dumped that snow load in western New York and southern Ontario. 2-day totals brought close to 40 inches of snow. The combination of roads drifted shut and the powerful wind that continued unabated for several days caused the city of London, Ontario to be isolated for days.
