At 3:25 a.m. EDT on Friday, the National Weather Service released a beach hazards statement valid between 6 a.m. EDT and 10 p.m. EDT for Alger County.

“Dangerous swimming conditions are expected due to high wave action and strong rip currents,” adds the weather service. “Current related fatalities and rescues in the past have occurred due to similar wave conditions at locations listed below: for Alger County: The Au Train River mouth at Au Train, the exposed regions of Grand Marais Harbor, and Pictured Rocks National Lakeshore.”

“High wave action and dangerous currents will lead to life threatening swimming conditions. Waves in rapid succession can tire swimmers quickly,” explains the weather service. “Remain out of the water to avoid hazardous swimming conditions.”
