Heavy Freezing Spray Warning Issued for Lake Huron Waters Through Monday Night
The National Weather Service has issued a Heavy Freezing Spray Warning for Lake Huron, warning of rapid ice accumulation that could lead to a catastrophic loss of vessel stability.
Alert Details
The National Weather Service in Detroit/Pontiac MI has issued a Heavy Freezing Spray Warning for specific offshore regions of Lake Huron. The alert is classified as severe, with hazardous conditions likely to impact maritime operations.
Affected Areas
The warning covers the following maritime zones:
- Lake Huron from 5NM east of Mackinac Bridge to Presque Isle Lt, 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 prepare for dangerous ice accumulation on their vessels. If possible, remain in port or avoid the warning area entirely. For those already at sea, conduct necessary mitigation measures to manage ice buildup.
Expected Conditions
Heavy freezing spray is expected to occur at a rate of 2 cm per hour or greater. This spray may rapidly accumulate on decks and superstructures. According to the NWS, operating a vessel in these conditions is hazardous as ice accretion can render mechanical and electronic components inoperative and may result in a catastrophic loss of stability. Maximum winds are anticipated around 4 AM EST Monday, with the largest waves expected to follow around 5 AM EST Monday.
Timeline
The warning is effective starting at 4:00 AM EST on Monday, February 23, 2026. The conditions are expected to persist throughout the day, with the alert currently set to expire at 10:00 PM EST on Monday.
