For waters beyond five nautical miles of shore on Lake Ontario

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...
A 30.8 inch high over the Saint Lawrence Valley will drift to the
Canadian Maritimes overnight. A broad 29.9 inch low tracking
northeastward across the Central and Upper Lakes will then push a
warm front across the lake on Friday. In the wake of this system,
high pressure over the Northern Plains Friday evening will then
briefly build across Lake Ontario late Friday night and Saturday,
before a deep storm system tracks from the Central Plains to the
Upper Great Lakes Saturday night and Sunday.
