Issued by NWS Boston/Norton MA
What:
For the Gale Warning, west winds 20 to 30 kt with gusts
up to 35 kt and seas 3 to 5 feet expected. For the Heavy
Freezing Spray Warning, heavy freezing spray at a rate of 2 cm
per hour or greater expected, and may rapidly accumulate on

Where:
Cape Cod Bay.
When:
For the Gale Warning, from 1 PM Friday to 7 AM EST
Saturday. For the Heavy Freezing Spray Warning, from 10 PM
Friday to 1 PM EST Saturday.
Impacts:
Operating a vessel in heavy freezing spray is
hazardous. Freezing spray may render mechanical and electronic
components inoperative. Rapid ice accretion on decks and
superstructures may result in a catastrophic loss of
stability. Strong winds will cause hazardous seas which could
capsize or damage vessels and reduce visibility.
Instructions: Mariners should prepare for dangerous accumulation of ice on
their vessel. If possible, remain in port, avoid the warning area
or conduct mitigation. During freezing spray conditions, the U.S.
Coast Guard advises mariners to check and ensure all life-saving
devices remain free of ice.
Mariners should alter plans to avoid these hazardous conditions.
Remain in port, seek safe harbor, alter course, and/or secure the
vessel for hazardous conditions.

Heavy Freezing Spray Warning
In effect from Thursday, Jan 22 2026 6:00 AM - Saturday, Jan 24 2026 6:00 AM
Issued by NWS Detroit/Pontiac MI
What:
Heavy freezing spray at a rate of 2 cm per hour or
greater expected, and may rapidly accumulate on vessels.
Where:
Lake Huron from 5NM east of Mackinac Bridge to Presque
Isle Lt beyond 5 NM off shore and Lake Huron from Presque Isle
Light to Sturgeon Point MI beyond 5NM off shore.
When:
The maximum winds are expected around 10 PM EST
Thursday with the largest waves expected around 4 PM EST
Thursday.
Impacts:
Operating a vessel in heavy freezing spray is
hazardous. Freezing spray may render mechanical and electronic
components inoperative. Rapid ice accretion on decks and
superstructures may result in a catastrophic loss of stability.
Instructions: Mariners should prepare for dangerous accumulation of ice on
their vessel. If possible, remain in port, avoid the warning area
or conduct mitigation.
Areas Impacted:
Lake Huron from 5NM east of Mackinac Bridge to Presque Isle Lt to the US/Canadian border beyond 5 NM from shore
Lake Huron from Presque Isle Lt. to Sturgeon Point MI 5NM off shore to US/Canadian border

In effect from Thursday, Jan 22 2026 6:00 AM - Saturday, Jan 24 2026 6:00 AM
Issued by NWS Detroit/Pontiac MI
What:
During the Heavy Freezing Spray Warning, heavy freezing
spray at a rate of 2 cm per hour or greater expected, and may
rapidly accumulate on vessels. During the Gale Warning, expect
sustained winds up to 29 knots from the west with gusts up to
36 knots. The largest significant waves will be 9 feet with a
potential maximum wave height of 13 feet.
Where:
Lake Huron from Sturgeon Point to Alabaster MI beyond
5NM off shore, Lake Huron from Port Austin to Harbor Beach
beyond 5NM Off Shore, Lake Huron from Harbor Beach to Port
Sanilac beyond 5NM Off Shore and Lake Huron from Port Sanilac
to Port Huron beyond 5NM Off Shore.
When:
The maximum winds are expected around 11 AM EST
Thursday with the largest waves expected around 1 PM EST
Thursday.
Impacts:
Operating a vessel in heavy freezing spray is
hazardous. Freezing spray may render mechanical and electronic
components inoperative. Rapid ice accretion on decks and
superstructures may result in a catastrophic loss of
stability. Strong winds will cause hazardous waves which could
capsize or damage vessels and reduce visibility.
Instructions: Mariners should prepare for dangerous accumulation of ice on
their vessel. If possible, remain in port, avoid the warning area
or conduct mitigation.
Mariners should alter plans to avoid these hazardous conditions.
Remain in port, seek safe harbor, alter course, and/or secure the
vessel for hazardous conditions.
Areas Impacted:
Lake Huron from Sturgeon Point to Alabaster MI 5NM off shore to US/Canadian border
Lake Huron from Port Austin to Harbor Beach 5NM Off Shore to the US/Canadian border
Lake Huron from Harbor Beach to Port Sanilac 5NM Off Shore to US/Canadian border
