text: # 1972 Portland–Vancouver tornadoes
  
  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 miles (14.0 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. 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 miles (80 km) inland.

  ### Portland, Oregon/Vancouver, Washington
  
  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 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 9-mile (14 km) journey before dissipating. The storm was classed as a tornado by the National Weather Service on April 6.
  
  In Portland, Oregon, the tornado damaged four boat moorings and 50 small boats. Damage in Oregon from the tornado totaled up to $250,000 (1972 USD). Vancouver, Washington suffered the most significant damage from the tornado. The tornado struck east Vancouver at 12:51 p.m. (PST) on April 5, 1972, where it destroyed a grocery store, along with Peter S. Ogden Elementary School injuring 70 students. 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 several vehicles were flipped as well. The Oregon National Guard and the Oregon State Police crossed the state border to help transport the injured and direct traffic in the aftermath of the tornado.
  
  ## Non-tornadic events
  
  High 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 0.12 inches (3.0 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 63 mph (101 km/h). Another weather station reported sustained winds of 80 mph (130 km/h).
  
  ## Aftermath
  
  Overall, the Portland–Vancouver F3 tornado killed six people and left $25.25 million (1972 USD) in damage. The small outbreak was the deadliest and most significant tornado event to occur in the Pacific Northwest, with winds of up to 206 miles per hour (332 km/h).
