for waters beyond 5 nautical miles of shore on lake superior.

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 29.4 inch low overtop lake superior this morning continues its 
eastward track today, deepening to 29.3 inches before reaching the 
southern ontario/quebec border tonight. ridging will build over the 
lake this weekend as the low exits into quebec and 30.6 inch high 
pressure develops over the great plains, with the ridge over the 
lake strengthening from 29.8 inches on saturday to 30.2 inches 
through sunday night. the ridge quickly breaks down early next week 
as a 29.4 inch trough sweeps across the lake on tuesday.
