Marquette, Mich. – Strong northwest winds are sweeping across Michigan’s Upper Peninsula today, with gusts near 40 mph creating hazardous conditions along Lake Superior and lake effect rain showers moving inland. Drivers and boaters face the greatest risks in the Keweenaw Peninsula, where peak winds will be strongest through the afternoon.
According to the National Weather Service in Marquette, winds will shift westerly by late Friday, sustaining speeds of 20 to 30 mph with higher gusts in exposed areas. Forecasters warn that waves will build quickly, making lakeshore travel and water activity dangerous from Marquette to Copper Harbor.
Air temperatures will remain cool, holding in the upper 40s across western counties and the low to mid-50s in central and eastern U.P. cities such as Escanaba, Ironwood, and Sault Ste. Marie. With winds persisting through the evening, residents are advised to secure outdoor items, limit shoreline activity, and use caution on bridges and open roads.
Lake effect rain showers are expected to continue intermittently into tonight before diminishing early Saturday. Additional advisories could be issued if wind speeds remain elevated.
