SPIRIT LAKE, Iowa (AP) – Authorities say docks were damaged and trees toppled by thunderstorms that passed through Iowa’s Great Lakes region in the northwest portion of the state, spawning a weak tornado. The Sioux City Journal says no injuries have been reported from Tuesday’s storms.

Philip Schumacher of the National Weather Service said Wednesday the tornado was spotted a little after 2:20 p.m., seven miles south of Lake Park in Dickinson County. He says it caused no damage. The twister was rated EF-0, with winds ranging from 65 to 85 mph.

Elsewhere, straight-line winds reaching 65 mph knocked down trees and power lines. Spirit Lake Fire Chief Pat Daly says a trailer at Center Lake lost its roof and says there were reports of boats flipped over and docks damaged.
