Tornado Risk in Swift County, MN
Swift County, MN: what NOAA's tornado record says
51 tornado tracks have crossed Swift County since 1952 by NOAA's count, roughly one every 1.5 years - the High band on this site's scale. That is the 88th percentile nationally for tornado frequency. Among 87 Minnesota counties in this dataset, Swift County ranks 6 for how often a tornado touches down.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Swift County in NOAA's 76-year database. Of its 51 recorded tracks, 46 were weak (EF0-1) and 5 significant (EF2-3).
Shelter and safe-room economics
Minnesota does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Swift County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
9,666 people live in Swift County, and a tornado outbreak's power loss usually reaches far more of Minnesota than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Swift County's figure does not tell you
Swift County's figure is county-wide, not address-specific. Swift County covers about 742 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. Swift County has about 9,666 residents.
