open lake forecast for lake ontario
national weather service buffalo ny

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 wavy cold frontal boundary averaging 29.6 inches will

lower michigan monday, and the mid-atlantic states tuesday. a 29.8 
inch low tracking across quebec will then push its associated cold 
front across the lake on wednesday, with another 29.6 inch low then 
developing across the central great lakes and or the ohio valley 
thursday.
