MILWAUKEE, WI (AP)-- The U.S. Coast Guard says warming temperatures this weekend could pose safety issues on Lake Michigan and frozen inland rivers, streams and ponds.
The Coast Guard is urging people to use extreme caution on the water and melting ice.
Ice thickness can vary, even in small areas. Water currents around narrow spots, bridges, inlets and outlets can cause thinner ice. The Coast Guard says stay away from cracks, seams, pressure ridges, slushy areas and darker areas.
