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, 30.30 inches, will remain anchored over
the eastern Great Lakes through Tuesday, providing tranquil
boating conditions. Deepening low pressure is forecast across the
northern Great Lakes Wednesday which will drive a strong cold
front across Lake Huron. This system will cause an increase in
winds and waves and provide rain to the region late Wednesday and
Wednesday night.
