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...High pressure...30.40 inches...will gradually push east
from the Central Plains into the Ohio Valley late Tuesday into late
Wednesday, which will gradually increase pressure and relax winds
across the Great Lakes region. Prior to high pressure situating
across the Ohio Valley, sustained wind speeds and gusts are expected
to hold steady into the morning hours on Wednesday, peaking between
20 - 25 knots, before relaxing by Wednesday afternoon. Otherwise, a
weak low...30.00 inches...will then push in across the Great Lakes
throughout Thursday, with pressure holding steady through Friday
morning.
