The tornado carved a nine-mile (14 km) path of destruction across the heavily populated Portland metropolitan area, leaving 6 people dead and 301 injured while causing $3–5 million (1972 USD) in damage. It was the deadliest tornado in the United States in 1972 and remains the deadliest tornado in the history of the Pacific Northwest.[1][2] It was the first F3 tornado to strike Oregon since June 3, 1894, and no tornadoes in Oregon or Washington have equalled its intensity ever since.[2] Storm historyThe National Weather Service tracked a very turbulent squall line of thunderstorms moving northeasterly across Portland, Oregon, the strongest of which was near the city of Tigard. The tornado formed from this storm and touched down near the edge of the Columbia River, moving 1½ miles before crossing the river. 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 river, it continued its {{convert|9|mi|km|adj=on}} journey before dissipating.[3] ImpactPortlandIn Portland, the tornado damaged four boat moorings and 50 small boats. Damage in Oregon from the tornado totaled up to $250,000 (1972 USD).[3][4] VancouverIn east Vancouver, the tornado struck at 12:51 p.m. (PST), where it destroyed a grocery store, along with Peter S. Ogden Elementary School injuring 70 students.[5] Nearby, the storm demolished a bowling alley, a drive-in theater screen and damaged around 100 homes, some severely. Trees and power lines were downed and vehicles were flipped as well.[6] Overall, the tornado killed six people and left $3–5 million (1972 USD) in damage.[1] Two F2 tornadoes and another F3 touched down in Coulee City, Kettle Falls and Creston in Washington state later that day, though these tornadoes caused no fatalities.[7][8] The small weather outbreak was the deadliest and most significant tornado event to occur in the Pacific Northwest, with winds of up to {{convert|206|mph|kph}}.[9] Non-tornadic eventsHigh winds brought by the thunderstorms caused minimal tree damage. In Tigard, the thunderstorm that spawned the tornado tore the roof off a warehouse and damaged several parked cars. A pressure jump of {{convert|0.12|in|mm}} was recorded by the National Weather Service. The Portland, Oregon National Weather Service office, approximately one mile east of the tornado touchdown, recorded winds gusting up to {{convert|63|mi/h|km/h|abbr=on}}. Another weather station reported sustained winds of {{convert|80|mi/h|km/h|abbr=on}}.[3] See also
