626 WHUS73 KDTX 152040 MWWDTX URGENT - MARINE WEATHER MESSAGE National Weather Service Detroit/Pontiac MI 440 PM EDT Mon Oct 15 2018 ...Gusts to gales through Tuesday... .Post frontal westerly winds gusts will top out around 35 knot gales across much of Lake Huron late this afternoon and early this evening within strong post frontal cold air advection. There will be an overall weakening trend to the winds overnight as the gradient relaxes and the cold air advection eases. Another cold front will approach the Great Lakes from the west Tuesday morning. The result will be a backing of the winds to the southwest. Ample low level cold air will support decent over-lake mixing depths so that wind speeds will increase. There is reasonably high confidence that gusts will once again top 35 knots gales on Lake Huron, with the strongest winds expected across Saginaw Bay out into the middle of Lake Huron. The cold front will traverse Lake Huron Tues afternoon and evening, resulting in a veering of the winds to the west-northwest. The front will mark another push of cold air, keeping winds elevated through the day Wednesday. There is actually another chance for gale force gusts on the open waters of Lake Huron Wednesday. A fairly active weather pattern in terms of wind speeds will persist across the lakes well into the weekend as yet another strong cold front is forecast to impact the area Friday night.

Refer to the latest marine forecasts for greater detail. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Gale Warning means winds of 34 to 47 knots are imminent or occuring. Operating a vessel in gale conditions requires experience and properly equipped vessels. It is highly recommended that mariners without the proper experience seek safe harbor prior to the onset of gale conditions. A Small Craft Advisory means that wind speeds of 21 to 33 knots are expected to produce hazardous wave conditions to small craft. Inexperienced mariners...especially those operating smaller vessels should avoid navigating in these conditions. && $$ LHZ361>363-462-160815- /O.CON.KDTX.GL.W.0021.000000T0000Z-181017T0000Z/ 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- Lake Huron from Sturgeon Point to Alabaster MI beyond 5NM off shore- Lake Huron from Port Austin to Harbor Beach beyond 5NM Off Shore- 440 PM EDT Mon Oct 15 2018 ...GALE WARNING REMAINS IN EFFECT UNTIL 8 PM EDT TUESDAY... * WIND AND WAVES: During the Gale Warning, expect sustained winds up to 35 knots from the west with gusts up to 44 knots.

The National Weather Service in Detroit/Pontiac has issued a Low Water Advisory which is in effect until 11 PM EDT this evening. * WATER LEVELS: The water level on the western basin of Lake Erie dropped to near the critical mark for safe navigation. The current level is 20 inches, which is 3 inches above the critical mark. The water level is expected to continue to fall through the early evening hours and should remain below the critical mark until 11 PM EDT this evening. Winds will begin to diminish this evening and this will allow the water level to rise back above the critical mark. * WIND AND WAVES: During the Small Craft Advisory, expect sustained winds up to 24 knots from the west with gusts up to 30 knots. The largest expected significant waves will be 3 feet with a potential maximum wave height of 4 feet. * TIMING: The maximum winds are expected around 9 PM EDT Tuesday with the largest waves expected around 3 PM EDT Tuesday. Refer to the latest marine forecasts for greater detail. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Low Water Advisory means water levels are expected to be significantly below average. Mariners should use extreme caution and transit at the slowest safe navigable speed to minimize impact. A Small Craft Advisory means that wind speeds of 21 to 33 knots are expected to produce hazardous wave conditions to small craft. Inexperienced mariners...especially those operating smaller vessels should avoid navigating in these conditions. && $$ LHZ441>443-160815- /O.CON.KDTX.SC.Y.0066.000000T0000Z-181017T1200Z/ Port Austin to Harbor Beach MI-Harbor Beach to Port Sanilac MI- Port Sanilac to Port Huron MI- 440 PM EDT Mon Oct 15 2018 ...SMALL CRAFT ADVISORY REMAINS IN EFFECT UNTIL 8 AM EDT WEDNESDAY... * WIND AND WAVES: During the Small Craft Advisory, expect sustained winds up to 31 knots from the southwest with gusts up to 40 knots.
