Heavy Freezing Spray and Storm Warnings Issued for Manitou Island to Point Isabelle MI

Alert Details

The National Weather Service in Marquette, MI, has issued a Heavy Freezing Spray Warning and a Storm Warning for the coastal waters of Lake Superior. These alerts signify a high risk to maritime safety due to extreme wind and ice conditions.

Affected Areas

The warnings apply specifically to the region from Manitou Island to Point Isabelle, Michigan (LSZ245).

What You Should Do

Mariners are strongly urged to remain in port. If currently at sea, avoid the warning area or conduct immediate mitigation efforts. Vessels should be secured for severe conditions, as rapid ice accretion on decks and superstructures can lead to a catastrophic loss of stability. Storm force winds and hazardous waves may capsize or damage vessels and significantly reduce visibility.

Expected Conditions

The region will experience west winds ranging from 30 to 40 knots, with peak gusts reaching up to 50 knots. Wave heights are expected to be between 5 and 8 feet. Additionally, heavy freezing spray is forecast to accumulate at a rate of 2 cm per hour or greater, which may render mechanical and electronic components inoperative.
