Great Lakes Ice Cover Spreading Rapidly; See Which Lake Set A New Record [View all]
Ice continued to build this past week on the Great Lakes due to the cold air and temperatures staying below freezing, and Lake Superior's new record shows it.
The lake is 92 percent frozen, toppling a 20-year-old record of 91 percent set on Feb. 5, 1994. That statistic helped total Great Lakes ice cover soar, and we can expect to see more form in coming days.
The air temperatures this past week averaged around five degrees below normal for the Great Lakes area. This amount of deviation from normal means it was a fairly cold week.
As of February 5, 2014, the entire Great Lakes system is now reportedly covered 77 percent with ice, according to the Great Lakes Environmental Research Laboratory. Last week at this time the ice cover was 66 percent. The 77 percent ice cover now still lags behind 1994, when the entire Great Lakes system had an average ice cover of 84 percent on February 5. This data is according to Jia Wang, physical oceanographer at the Great Lakes Environmental Research Center in Ann Arbor, MI.
