Great Lakes Storm Surges
October 25-27, 2001

A large storm event characterized by high winds was observed throughout the western Great Lakes Basin on October 25-27 of 2001. Winds from the west (NW over Superior, SW over Michigan, Huron and Erie) rose to speeds in excess of 50 knots (58mph/93kph) on the 25th, continuing through the 26th and slowly abating on the 27th. The winds created waves of 15-20 foot heights (4-6m) moving eastward throughout central and eastern Lake Superior, the eastern half of Lake Michigan, the eastern half of Lake Huron, and central Lake Erie which reached their peaks late on the 26th. Wind and wave action resulted in a significant storm surge on each lake: recorded surge for Lake Erie exceeded 6 ft (1.8m), for Lake Huron 3 ft (1m), for Lake Michigan 1.3 ft (0.4 m), and for Lake Superior 1.3 ft (0.4 m). Storm surges were followed by seiches of lesser magnitude (less than 1 foot) as the winds abated slowly and without dramatic shift in direction.
