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...Breezy north to northeast winds are expected to calm a bit
tonight as high pressure of 30.4 inches pushes east tonight into
the central and eastern Great Lakes region. The high will then
build and slowly move across southeast Canada through the
weekend, with modest south to southeast winds developing over Lake
Michigan Saturday into Saturday night.

Gusty south to southeast winds are then forecast Sunday into
Sunday night, becoming south to southwest into early next week.
Waves should build during this period over the northern and
central portions of the lake.
