The National Weather Service says a damage assessment in Bayview determined fallen trees and power lines were caused by an EF-1 tornado on Wednesday.
A NWS survey team concluded that a waterspout moved ashore just before 3 p.m. and touched down as a brief tornado before lifting.
The tornado was moving very quickly and scientists say it affected a neighborhood on the east side of the Bayview Golf Club.
Several pine trees, about three feet in diameter, had their trunks snapped about 12 ft up. There was also a large cedar tree, two feet in diameter, that was snapped.
Additional damage included a large shed that had its tin roof torn off and thrown about 25 yards, shingles that were torn from several homes, and large limbs that were blown down.
There were no reports of injuries.
