DETROIT (AP) – The U.S. Coast Guard is urging people to use caution on Great Lakes waterways due to warmer temperatures and unstable ice.
The warning specifically mentions Lake Superior and the northern parts of Lake Michigan and Lake Huron.
People are at risk of falling through the ice during above freezing-temperatures. The Coast Guard also notes that ice-breaking in harbors, ports and waterways also is increasing throughout the Great Lakes in preparation for the March 25 opening of the Soo Locks.
The Coast Guard says people should stay away from cracks, seams, pressure ridges, slushy areas and darker areas of ice since these could be hazards.
