Overview
This strong fall storm system produced storm-force gusts (defined as greater than 47 kt, or 54 mph) on Lake Superior as well as lakeshore flooding along the Bay of Green Bay shoreline. The water level on the Lakes Michigan-Huron system was already at nearly a record high from about a year of anomalously high precipitation. Combined with the prolonged east wind with this storm pushing water to the west, lakeshore flooding affected nearly all of the Bay of Green Bay. |
