Northern Oregon, Washington
The 1972 Portland–Vancouver tornadoes were caused by an unusually intense squall line with embedded strong tornadoes that struck Oregon and Washington on Wednesday, April 5, 1972. Of the four tornadoes, the most catastrophic event was a deadly F3 tornado that struck Portland, Oregon, and Vancouver, Washington, the first F3 tornado to strike Oregon since June 3, 1894. It tracked 8.7 mi km across the heavily populated Portland–Vancouver metropolitan area, causing heavy damage, killing six people, and injuring 300 while causing $25.25 million (1972 USD) in damage. It was tied as the deadliest tornado in the United States in 1972 and remains the deadliest tornado in the history of the Pacific Northwest."Tornado of April 5, 1972, Vancouver, Washington" Details Waymark 2006-12-05 http://www.waymarking.com/wm/details.aspx?f=1&guid=5361b209-8bc3-430b-bd7f-eb1df084d896 In all, the outbreak killed six, injured 301, and caused $25.55 million in damage.
Meteorological synopsis
A sharp cold front triggered an intense squall line that moved into the Pacific Northwest during the late morning hours of April 5, 1972. After moving inland, the storms produced strong winds, large hail, and tornadoes to the region. Weakening of the storms did not take place until late that evening; by then storms had moved over 50 mi km inland.

The 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 1 + 1/2 mi km on 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 9 mi km on journey before dissipating.National Weather Service 2006 NWS Forecast Office - Portland Oregon - Some of the Area's Tornadoes NWS division of NOAA 2021-02-23 http://www.weather.gov/pqr/paststorms/tornado.php dead https://web.archive.org/web/20181003100816/https://www.wrh.noaa.gov/pqr/paststorms/tornado.php 2018-10-03 The storm was classed as a tornado by the National Weather Service on April 6.Spiro Richard Vancouver twister classified tornado by weather bureau https://www.newspapers.com/clip/42955279/longview_daily_news/ Longview Daily News April 7, 1972 Longview, WA 5 Newspapers.com While officially rated F3, the tornado was assessed as F2 by tornado historian Thomas P.
