What You Should Do
Operating a vessel in these conditions is extremely hazardous. Mariners should prepare for dangerous ice accumulation which can render mechanical and electronic components inoperative. Rapid ice accretion on decks and superstructures may result in a catastrophic loss of stability.
Mariners are urged to alter plans to avoid these hazardous conditions. If possible, remain in port, seek safe harbor, and secure vessels for high winds and heavy waves which could capsize or damage craft and reduce visibility.
