what are waterspouts

Waterspouts are similar to tornadoes at first glance and some even are just tornadoes that have moved over water. Waterspouts can come in tornadic or fair; tornadic waterspouts are tornadoes that form on land, but then move over a large body of water these tend to be more destructive in nature as they can have extremely fast winds. Fair waterspouts then to be more common and less destructive in nature when compared to tornadoes. While tornadoes form from the air to land fair waterspouts from in the water and move upwards towards the air. This is because of a great difference in the warm body of water vs the extremely cold air causes the water spouts to form. As a result, they tend to form in Michigan during the fall time in the months of August September and October.

"Waterspouts occur most frequently in northern Michigan during the months of August, September, and October, when the waters of the Great Lakes are near their warmest levels of the year. Waterspout formation typically occurs when cold air moves across the Great Lakes and results in large temperature differences between the warm water and the overriding cold air. They tend to last from about two to twenty minutes, and move along at speeds of 10 to 15 knots."
