Gale warnings, small craft advisories remain on Lake Superior near shore

Boaters along the North Shore faced a dangerous Saturday as gale warnings remained in effect for Lake Superior near shore from Silver Bay Harbor to Two Harbors and from Two Harbors to Duluth until 7 p.m. CDT, with small craft advisories continuing through 10 p.m. for nearby stretches including Taconite Harbor to Silver Bay Harbor and waters east and west of that zone.

The National Weather Service in Duluth said the most serious risk came from northeast winds gusting to 35 knots in the gale-warning area, with waves building to 5 to 7 feet. In the same marine outlook, most of the remaining western Lake Superior nearshore waters were expected to see northeast gusts up to 25 knots and waves ranging from 3 to 7 feet, conditions that can turn a routine crossing into a hard run for small boats.

That forecast mattered most in Lake County, where the warning zone covered the North Shore corridor from Grand Marais through Taconite Harbor, Silver Bay Harbor and Two Harbors, then down toward Duluth. The nearshore marine forecast applies to waters within five nautical miles of shore, putting harbor entrances and exposed shoreline stretches directly in the path of the strongest wind and wave action.

For the Duluth to Port Wing zone, the forecast called for northeast winds of 15 to 20 knots Saturday night with gusts around 30 knots and waves of 4 to 6 feet, occasionally reaching 8 feet, before easing by early morning. That kind of short-period wave pattern can make docking and transit difficult near Silver Bay Harbor and Two Harbors, especially for charter operators, anglers, and anyone moving close to piers, breakwalls or harbor mouths.

The warning and advisory pattern also reached beyond Lake County, extending across the western end of Lake Superior to Port Wing, Wisconsin, and out to the Outer Apostle Islands. Advisories were posted for Grand Portage to Grand Marais, Grand Marais to Taconite Harbor, Taconite Harbor to Silver Bay Harbor, Port Wing to Sand Island, Sand Island to Bayfield and the Outer Apostle Islands beyond 5 nautical miles from mainland shore.

For anyone planning weekend travel, shoreline recreation or a harbor departure near Silver Bay, Two Harbors or Duluth, the safest choice was to stay off the water until the wind dropped and the waves settled. The Great Lakes marine forecast service is built to warn for exactly these conditions, and Saturday’s setup left little margin for small craft.
