Strong winds will cause hazardous waves which could capsize or damage vessels and reduce visibility. 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. 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. && $$ LHZ361-362-282115- /O.EXT.KDTX.GL.W.0008.000000T0000Z-200228T2200Z/ /O.EXT.KDTX.UP.W.0003.000000T0000Z-200228T2200Z/ Lake Huron from 5NM east of Mackinac Bridge to Presque Isle Lt beyond 5 NM off shore- Lake Huron from Presque Isle Light to Sturgeon Point MI beyond 5NM off shore- 307 AM EST Fri Feb 28 2020 ...GALE WARNING NOW IN EFFECT UNTIL 5 PM EST THIS AFTERNOON... ...HEAVY FREEZING SPRAY WARNING NOW IN EFFECT UNTIL 5 PM EST THIS AFTERNOON... * WHAT...During the Heavy Freezing Spray Warning, heavy freezing spray at a rate of 2 cm per hour or greater may rapidly accumulate on vessels.
