Thursday's waterspout can also be classified as a EF0 tornado according to the National Weather Service in Duluth. The waterspout crossed over park point as it headed southwest over the bay. For the brief period that it was over land, it is classified as a tornado. There were no reports of damage, but the wind was high enough to rattle some pontoons at the Sky Harbor Airport. An EF0 tornado is estimated to have winds at 65-85mph.

According to Carol Christenson, Warning Coordination Meteorologist at the NWS, there hasn't been a tornado in our city limits in recorded history. "There was one outside of city limits back in 1986", Christenson said.

The tornado turned back into a waterspout as it moved over the St. Louis Bay toward Barker's Island. It then went back to being a tornado as it struck land South of Fairlawn Museum in Superior and then quickly dissipated leaving no damage.
