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, 29.90 inches, builds in tonight through Thursday
leading to drier and calmer marine conditions. Strong northern
Ontario low pressure, 29.00 inches, sends an arctic cold front
through the central Great Lakes Friday night bringing the next
chances to see northwest gales. A Gale Watch is in effect for
northern Lake Huron as a result.
