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.

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.
