High winds, storms, wave action increase hazards
The U.S. Army Corps of Engineers, Detroit District, urges caution around Great Lakes harbor piers and breakwaters, particularly during high wind and wave events. Accidents can occur near harbor structures during turbulent weather late in the year. The lakeshore attracts residents and visitors who may not be aware of the powerful impacts strong winds and storms can bring to shorelines and harbor structures.
