open lake forecast for lake ontario
national weather service buffalo ny
144 am edt wed sep 22 2021

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 30.5 inch high off the nova scotia coastline will 
gradually weaken overnight as a cold front slowly pushes east 
across the central great lakes. a wave of low pressure will then 
develop along this front on wednesday and pivot to the central 
great lakes on thursday...when it will also slowly push the front 
eastward across the lake.
