High Winds Set Ice Adrift in Green Bay
On 11 March 2009, strong northwesterly winds (gusting as high as 70 mph at Grand Marais in the Upper Peninsula of Michigan, and 57 mph at Washington Island in northeastern Wisconsin) caused a large portion of the land-fast ice in the far northern portion of Green Bay to break away and begin drifting eastward into Lake Michigan. The speed of the ice field drift was in the 15-25 knot range.
A 250-meter resolution “true color” image (below) shows increased detail of the ice field structure.
Also note the long, narrow southwest-to-northeast oriented tornado damage path (from the 07 June 2007 tornado event), located about 30 miles (48 km) inland to the west of Green Bay.
