PORT ORCHARD, Wash. (AP) -- The National Weather Service says preliminary investigation shows an extremely rare tornado that touched down west of Seattle Tuesday was rated an EF2.
That means it is considered to have been a significant tornado. Estimated peak winds during the tornado were up to 130 mph.
The Weather Service surveyed the damage and found homes without roofs, trees torn out of the ground and windows blown out of cars. It says significant tree and structure damage was noted along the twister's path.
No injuries have been reported.
Kitsap County Search and Rescue workers along with search dogs worked into Tuesday night. They swept the area checking for people who may have been injured or stranded but found none.
The storm severely damaged several homes and caused more than 1,000 to lose power.
Authorities say as many as 450 homes may have suffered damage.
Port Orchard is about 15 miles west of Seattle, across Puget Sound on the Kitsap Peninsula.
