Alert Details
The National Weather Service in Detroit/Pontiac MI has issued a Heavy Freezing Spray Warning for portions of Lake Huron. This alert is in effect alongside a Gale Warning, both triggered by hazardous marine conditions expected to impact the region.
Affected Areas
The warning covers the following geographic zones:
- Lake Huron from 5NM east of Mackinac Bridge to Presque Isle Light, extending to the US/Canadian border beyond 5 NM from shore.
- Lake Huron from Presque Isle Light to Sturgeon Point MI, beyond 5NM from shore.
What You Should Do
Mariners are strongly advised to alter plans to avoid these hazardous conditions. Recommended actions include:
- Remaining in port or seeking safe harbor immediately.
- Avoiding the warning area entirely if possible.
- Preparing for dangerous accumulation of ice on vessels.
- Securing vessels and conducting mitigation for rapid ice accretion.
Expected Conditions
- Freezing Spray: Heavy freezing spray is expected at a rate of 2 cm per hour or greater, which may rapidly accumulate on vessel decks and superstructures.
- Wind: Sustained winds from the west are forecast up to 30 knots, with gusts reaching 40 knots.
- Waves: Significant waves are expected to reach 10 feet, with potential maximum wave heights of 15 feet.
- Impacts: Operating a vessel in these conditions is extremely hazardous. Ice accumulation can render mechanical and electronic components inoperative and lead to a catastrophic loss of stability. Strong winds and high waves could capsize or damage vessels and significantly reduce visibility.
