DULUTH, Minn. — The National Weather Service in Duluth has issued a warning for hazardous winds and rough waters on western Lake Superior beginning Wednesday and lasting into Thursday. Mariners, recreational boaters, and shoreline visitors are urged to use extreme caution as gusts and waves build through the midweek period.
Strong Winds and High Waves Expected
Southwest winds will strengthen steadily on Wednesday before shifting to the northeast on Thursday. Gusts are expected to reach 27 to 30 knots on open waters, particularly near the Western Lake Superior Buoy. These winds will generate steep waves, reduced visibility, and dangerous boating conditions.
Key stretches of the lake, including the corridor from Grand Marais to Two Harbors, will be most affected, with exposed locations such as Outer Island, Stockton Island, and Devils Island experiencing gusts above 25 knots. The risk of capsizing for smaller vessels will rise significantly under these conditions.
Small Craft Advisory Likely
The National Weather Service anticipates that Small Craft Advisories will be issued as conditions worsen. The combination of strong winds and choppy waves makes the midweek period especially hazardous for small boats, kayaks, and canoes.
Recreational boaters in Duluth, Superior, and surrounding harbors are strongly encouraged to postpone outings until winds ease by late Thursday. Even experienced mariners could face challenges navigating in the open waters during this event.
Shoreline Impacts
Residents along Minnesota’s North Shore should also be prepared for impacts beyond the water. Rough surf and strong shoreline currents will pose hazards to swimmers, anglers, and others near the lakefront. Those planning outdoor activities should keep a safe distance from breaking waves and unstable shorelines.
Looking Ahead
Winds are expected to gradually diminish by Friday, giving way to calmer conditions through the weekend. However, forecasters caution that another shift in the weather pattern is possible early next week, which could bring renewed challenges for mariners and shoreline communities.
