The Great Lakes Blizzard of January 1971 affected almost the entire Great Lakes region of North America, as well as the western St. Lawrence Valley and northern New England between January 25 and 28, 1971 before a second severe snowstorm hit many of the same areas between January 28 and 31, 1971. The areas that felt the fiercest effects of the dual storms, that being moderate or heavy snow, sustained high winds, and zero visibility due to blowing snow, included southern Wisconsin, most of Michigan, Southern Ontario, northeastern Ohio, northwestern Pennsylvania, most of upstate New York and Southern Quebec, while northern Wisconsin, northern Indiana, northeastern Ontario, and northern Vermont experienced blizzard conditions from the first of the storms.
