OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
241 AM CDT Mon Oct 25 2021

FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.

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

Low pressure around 29.5 inches will continue to push east slowly
moving out of the region later today with continued strong east
winds expected. Thus easterly gales will prevail this morning
over the southern half of the lake, backing to northeasterly gales
later today. A Gale Warning remains in effect through the day
today over the southern half of the lake. Northerly winds will
then gradually weaken tonight and Tuesday morning as high
pressure approaches from the west.
