for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

stronger northwesterly winds will continue to pick up across 
southern lake michigan this evening as low pressure deepens to 
around 28.6 inches off the mid-atlantic coast while high pressure 
over manitoba builds to around 31.1 inches as it pushes eastward 
into ontario tonight. gales are expected across the southern two-
thirds of the open waters of lake michigan, thus a gale warning 
remains in effect from this evening into midday monday. with the 
brisk conditions, moderate freezing spray is expected, with brief 
periods of heavy freezing spray possible in the central to northern 
third of the lake. 

weakening high pressure to around 30.6 inches continues to push 
eastward through the day monday with winds gradually easing 
overnight. southerly winds look to develop across the lake tuesday 
as a low pressure deepening to around 29.3 inches builds down from 
the dakotas and across lake superior/northern lake michigan tuesday 
afternoon and evening. will see winds shift more west-northwest 
behind the low and associated cold front. will see strong winds 
gusts up to around 30 knots for this timeframe, and while potential 
is lower, still cannot rule out a few gale force gusts later tuesday 
into early wednesday morning.
