Waves are provided as a range of significant wave heights, which is the average of the highest 1/3 of the wave, along with the average height of the highest 10% of the waves which will occasionally be encountered. .SYNOPSIS... Easterly winds will continue across the lake this morning as low pressure of 29.2 inches continues northeast towards the Great Lakes region. Winds today will remain easterly, but will begin to accelerate throughout the day as the low approaches, leading to the likelihood of gales across much of the lake by this evening. As such, we have upgraded the Gale Watch to a Gale Warning that is in effect from this evening through Wednesday evening for various parts of the lake. Winds across much of the lake will decelerate and shift southerly to southwesterly Wednesday as the low moves north across central Wisconsin, but easterly gales are still possible over the far northern portion through Wednesday evening before also turning westerly and decelerating. Westerly winds will then continue Thursday morning before becoming southwesterly by Thursday afternoon for the entire lake as the low departs the area.
