URGENT - MARINE WEATHER MESSAGE
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
947 AM EDT WED SEP 28 2016

...PROLONGED EASTERLY FLOW TO BRING BUILDING WAVES...

.A LARGE AREA OF SURFACE LOW PRESSURE NOW OVER NORTHEASTERN WISCONSIN
WILL PUSH SOUTHWARD DOWN THE LONG AXIS OF LAKE MICHIGAN BEFORE
EMERGING OVER PORTIONS OF THE OHIO RIVER VALLEY BY THIS EVENING. AS
A RESULT, SURFACE WIND DIRECTIONS WILL RESPOND BY BECOMING EASTERLY.
SURFACE WINDS TODAY WILL REMAIN RELATIVELY WEAK BEFORE THE EAST
WINDS INCREASE TONIGHT INTO THE 20 TO 30 KNOT RANGE. SMALL CRAFT
ADVISORIES WILL BE IN EFFECT BEGINNING TONIGHT, THEN PERSISTING
THROUGH THE WEEK AND POSSIBLY INTO THE WEEKEND. THIS IS EXPECTED TO
MANIFEST ITSELF WITH WAVE HEIGHTS IN THE 5 TO 7 OR 6 TO 8 FOOT
RANGE FOR A LONG DURATION AT THE END OF THE WEEK.

A STEADY FLOW OF MOISTURE AROUND THE EAST AND NORTHEAST SIDE OF THIS
UPPER LOW WILL MAINTAIN VERY UNSETTLED CONDITIONS ACROSS THE CENTRAL
GREAT LAKES WITH WIDESPREAD SHOWER ACTIVITY AND EMBEDDED THUNDER AT
TIMES. WATERSPOUT CHANCES WILL INCREASE TODAY AS THE CHANCE FOR
CONVECTION INCREASES. IN FACT, THERE APPEARS TO BE A PRETTY DECENT
CHANCE AT A FEW WATERSPOUTS OVER PARTS OF THE AREA TODAY AS OVER
WATER INSTABILITY BECOMES RATHER IMPRESSIVE. THIS SEEMS MOST LIKELY
OVER PARTS OF LAKE ERIE WHERE THE COVERAGE OF SHOWERS AND A FEW
STORMS WILL BE MOST ROBUST.
