Ice is already starting to develop on Michigan's Great Lakes. This is the earliest ice on some of the Great Lakes in at least 40 years.
According to the
Great Lakes Environmental Research Laboratory, on November 20, 2014, three of Michigan's Great Lakes had ice starting to form. Lake Superior and Lake Michigan were one-half percent ice covered, while Lake Huron had one percent ice. Lake Erie was not reporting any ice as of Nov. 20, 2014.
