* WHAT... For the Gale Warning, northwest winds 30 to 40 kt with gusts up to 45 kt and seas 6 to 9 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 vessels.

* WHEN... For the Gale Warning, from 7 PM this evening to 4 PM EST Saturday. For the Heavy Freezing Spray Warning, from 10 AM Friday to 4 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.
* ADDITIONAL DETAILS... Dangerously low wind chills are expected Friday into Saturday, with the lowest wind chills expected Friday night. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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 severe conditions.
