Kipp Vaughn, who runs surveillance cameras for the MBA, said it was the first tornado he saw near the bridge in more than three years in the area.
Funnel clouds are common in the Great Lakes at this time of year, according to MLive meteorologist Mark Torregross.
“This is caused by the cold air that is now penetrating upward and the still relatively warm waters of the Great Lakes,” he said. “Warm air at the surface of the lake rises, and cold air descends. Then the rotation begins and a water tornado forms. ”
