Tornado Risk in Jackson County, OR
Jackson County's tornado history, by the numbers
Zero tornado tracks recorded in Jackson County since 1950, per NOAA's Storm Prediction Center. That reflects the actual geography, not a hole in the record.

The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Jackson County in NOAA's 76-year database. Of its 0 recorded tracks, 0 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 Jackson 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 Jackson County's figure does not tell you
Jackson County's figure is county-wide, not address-specific. Jackson County covers about 2,783 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. Jackson County has about 221,331 residents.
