URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
338 PM EST THU NOV 23 2017

...SOUTHWEST GALES ON FRIDAY...

.AREA LAKES WILL REMAIN UNDER GUSTY SOUTHWEST CONDITIONS THROUGH
TONIGHT, AS RETURN FLOW STRENGTHENS BEHIND SURFACE HIGH PRESSURE
OVER THE EASTERN U.S. WHILE THE GUSTIEST OF THE SOUTHWEST WINDS WILL
OCCUR OUT OVER THE OPEN WATERS OF THE LAKE HURON BASIN DURING THIS
TIME, WAVE HEIGHTS AND WIND GUSTS WILL RESPOND ENOUGH IN THE LONG
SOUTHWEST FETCH TO NECESSITATE A SMALL CRAFT ADVISORY OVER OUTER
SAGINAW BAY. THE GRADIENT WILL STRENGTHEN FRIDAY IN ADVANCE OF AN
APPROACHING COLD FRONT. THIS WILL BRING SOUTHWEST WINDS OF 25 TO 30
KNOTS ACROSS LAKE HURON. WHILE INCREASING STABILITY MAY TEND TO
LIMIT THE OVERALL GUST POTENTIAL, THIS WILL ALLOW GUSTS TO REACH
GALES FOR A PERIOD OVER THE OPEN WATERS. WINDS TURN WEST-NORTHWEST
AND REMAIN STRONG AS COLDER AIR ARRIVES SATURDAY.
