Alert Details
The National Weather Service in Marquette, MI, has issued a series of marine alerts, including a Heavy Freezing Spray Warning, a Storm Warning, and a Gale Warning. These alerts indicate severe conditions for mariners, with the potential for rapid ice accumulation and hazardous wind and wave conditions.
Affected Areas
The warning covers the following maritime regions:
- Seul Choix Point to Point Detour, MI
- 5NM East of a line from Fairport, MI, to Rock Island Passage
What You Should Do
Mariners are strongly advised to prepare for dangerous ice accumulation on their vessels. If possible, remain in port or avoid the warning area entirely. Those already at sea should conduct mitigation efforts, alter course, and secure the vessel for severe conditions. Rapid ice accretion on decks and superstructures may result in a catastrophic loss of stability.
Expected Conditions
- Freezing Spray: Heavy freezing spray is expected at a rate of 2 cm per hour or greater. This can render mechanical and electronic components inoperative.
