Tornado Risk in Linn County, OR
Linn County's tornado history, by the numbers
5 tornado tracks have crossed Linn County since 1994 by NOAA's count, roughly one every 15.2 years - the Minimal band on this site's scale. That is the 17th percentile nationally for tornado frequency. Oregon has 36 counties in this dataset; Linn County ranks 12 of them by frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Linn County in NOAA's 76-year database. Of its 5 recorded tracks, 5 were weak (EF0-1) and 0 significant (EF2-3).
Shelter and safe-room economics
Oregon does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Linn County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
Power loss after a tornado outbreak in Oregon often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Linn County's figure does not tell you
Linn County's figure is county-wide, not address-specific. Linn County covers about 2,290 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Linn County has about 132,474 residents.
