The highest rating in the archive
The strongest rating represented in Oregon is F/EF3. When several records share that rating, this page highlights the one with the longest recorded path: 8.7 miles on April 5, 1972.
This is a database summary, not a definitive ranking of every historical tornado. Early events may have incomplete paths or retrospective ratings.
Rating is based on damage
Survey teams assign EF ratings by examining damage indicators and degrees of damage. The scale estimates a wind range from the damage that occurred; it does not measure every tornado’s maximum wind directly.
A violent tornado crossing open land may leave few indicators, while a lower-rated tornado can still be deadly when exposure and shelter are poor.
Impact across the full record
The state archive totals 305 injuries and 6 fatalities. Those human impacts cannot be compared by rating alone because warning access, time of day, construction, population, and storm speed matter.
Use historic events to improve present-day plans: reliable alerts, rapid shelter, head protection, and careful post-storm movement reduce avoidable risk.

Data source and limits
Counts on this page come from the NOAA Storm Prediction Center historical tornado archive for 1951–2024. Older records are less complete, weaker tornado reporting increased with population and technology, and ratings changed from the Fujita scale to the Enhanced Fujita scale in 2007. A record is not a forecast.
