The Great Lakes are now 77% ice covered. The data comes from the Great Lakes Environmental Research Laboratory.
Ice continued to build the past week due to the cold temperatures and wind chills. Although the ice-coverage hasn't reached 1994's record of 84%, Lake Superior hit a new record as of February 5th. Superior is now 92% frozen, compared to 91% 20 years ago. Lake Michigan gained almost 10% of ice over a week, now standing at 51%. It is predicted that Lake Huron could be almost frozen over by the end of the week. Lake Ontario is the lowest of any of the lakes... But Lake Erie, the shallowest of all the lakes, is at the highest with 96%. Ice coverage is expected to continue to increase throughout the next few weeks based on cold temperatures.
