[edit] Storm history
A very turbulent squall line of thunderstorms moved northeast across Portland, Oregon and was tracked by the National Weather Service. The strongest thunderstorm was tracked near the town of Tigard. The tornado formed from this thunderstorm and touched down near the edge of the Columbia River. The tornado moved 1 1/2 miles before crossing the Oregon/Washington border. The the tornado was difficult to observe because of the fog and the mud and flying debris drawn up by the tornado. After making landfall on the Washington side of the Columbia River, the tornado continued its 9 mile journey before dissipating. [2]
