WHAT
For the Gale Warning, north winds 25 to 35 kt with gusts up to 50 kt and seas 8 to 13 ft. 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 vessels.
WHERE
Stephens Passage.
WHEN
For the Gale Warning, until 6 PM AKST Sunday. For the Heavy Freezing Spray Warning, from 3 AM to 6 AM AKST Sunday.
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.
ADDITIONAL DETAILS
Strongest winds out of interior passes.
Recommendations
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.
