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...Low pressure, 29.50 inches, continues to draw a frontal zone across
the area early this morning before settling southeast of the area by
mid-day. High pressure, 30.50 inches, then builds in from the
northwest to support overall benign marine conditions through the
weekend. The exception to this is northern Lake Huron where breezy
northwest flow and elevated wave action exist for most of today.
