The blizzard of 1977 hit Western New York and Southern Ontario from January 28 to February 1 of that year. Daily peak wind gusts ranging from 46 to 69 mph (74 to 111 km/h) were recorded by the National Weather Service in Buffalo, with snowfall as high as 100 in (254 cm) recorded in areas,[1] and the high winds blew this into drifts of 30 to 40 ft (9 to 12 m).[2] There were 23 total storm-related deaths in Western New York, with five more in northern New York.[3]
Certain pre-existing weather conditions exacerbated the blizzard's effects. November, December and January average temperatures were severely below normal. Lake Erie froze over by December 14, 1976; when this occurs, lake-effect snow does not occur 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.
Lake Erie was covered by a deep, powdery snow; January's unusually cold conditions limited the usual thawing and refreezing, so the snow on the frozen lake remained powdery. The drifted snow on roadways was difficult to clear because the strong wind packed the snow into a solid state. In addition to the roads becoming impassable, motorists had to deal with vehicles breaking down due to the combination of very cold temperatures, very high winds and blowing snow.
In the hardest-struck areas, snowmobiles became the only viable method of transportation. In Western New York and Southern Ontario's Niagara Peninsula, snow which was accumulated on frozen Lake Erie and snow on the ground at the start of the blizzard provided ample material for the high winds to blow into huge drifts. The combination of bitter cold, high winds, and blowing snow paralyzed areas affected by the storm. Lake Ontario rarely freezes over, which meant northern New York had to deal with considerable lake-effect snow. Coupled with the existing snow cover and wind, this had a similar effect.
