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

SYNOPSIS

Gusty west winds winds are expected today and tomorrow, as low pressure moves from Ontario into Quebec, and high pressure extends from the northern High Plains across the middle portion of the country. The westerly winds will become lighter on Sunday as a surface ridge approaches from the west, and then will turn southwesterly early next workweek.
