for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...a weak low pressure system, 30.00 inches, will track

along the stalled front wednesday evening which will reinforce
the arctic airmass and bring borderline gales across lake huron
wednesday late afternoon and early evening.
