1/3 of the wave spectrum. Occasional wave height is the average of

.SYNOPSIS...Breezy north to northeast winds are expected to calm a bit

the central and eastern Great Lakes region. The high will then
build and slowly move across southeast Canada through the

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.
