WHAT
For the Storm Warning, north winds 40 to 50 kt with gusts up to 60 kt and seas 9 to 14 ft. For the Heavy Freezing Spray Warning, heavy freezing spray at a rate of 2 cm per hour or greater may rapidly accumulate on vessels. For the Gale Warning, north winds 30 to 40 kt with gusts up to 55 kt and seas 7 to 12 ft expected.
WHERE
Northern Lynn Canal.
WHEN
For the Storm Warning, until 3 PM AKST Sunday. For the Gale Warning, from 3 PM to 6 PM 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. Storm force winds and hazardous seas will capsize or damage vessels and reduce visibility.
ADDITIONAL DETAILS
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 remain in port, alter course, and/or secure the vessel for severe conditions.
