Marquette, Mich. – Swimmers along Lake Superior are being urged to use extreme caution Thursday as dangerous waves and currents pose a moderate swim risk across Marquette County. Beaches at Middle Bay near Presque Isle, Little Presque Isle, and McCarty’s Cove are highlighted as particularly hazardous.
According to the National Weather Service in Marquette, breaking waves and rip currents are likely today, with conditions strong enough to challenge even experienced swimmers. Officials warn against entering the water near piers, break walls, and river outlets where currents can intensify.
At the same time, cooler air is moving into Michigan’s Upper Peninsula and will linger through early next week. Highs today range from 60 to 72 degrees with showers over the western U.P. Friday. Thunderstorms are expected to develop Saturday and continue into Sunday and Monday, bringing periods of heavy rain and gusty winds.
Travelers should be prepared for wet roads and brief delays during storms, while residents are encouraged to keep devices charged in case of power outages. Anyone entering Lake Superior today should stay close to shore and avoid dangerous areas.
Conditions remain unstable, with more advisories possible through the weekend.
