Houghton, Michigan — Lake-effect snow is expected to intensify this afternoon, creating hazardous travel and reduced visibility across the Keweenaw Peninsula.
According to the National Weather Service in Marquette, persistent northwest winds will continue to fuel lake-effect snow bands today through tonight. Snowfall totals of 3 to 6 inches are expected across much of the Keweenaw, including Houghton and Hancock, with lighter totals of 1 to 4 inches across other northwest wind snow belts.
Forecasters say snowfall rates may briefly approach a half inch per hour in stronger bands. The snow is expected to be fine and dry, making it especially prone to blowing and drifting. Visibility could drop below one-half mile at times, particularly during the late afternoon and evening hours.
Westerly wind gusts of 30 to 35 mph are also expected, compounding travel issues on exposed roadways. U.S. Highway 41 and M-26 are among the routes most likely to see rapidly changing conditions, especially in open areas and near higher terrain.
The National Weather Service cautions drivers to allow extra time, reduce speeds, and be prepared for sudden whiteout conditions. Even brief bursts of heavy snow could make untreated roads slick within minutes.
Snow showers are expected to gradually taper late tonight into Thursday morning as winds weaken and shift.
For students, commuters, and early-shift workers, the most difficult travel conditions are likely during the evening commute and overnight hours, when blowing snow and reduced visibility will be most pronounced.
