Tornado Risk in Morrison County, MN
Morrison County, MN: what NOAA's tornado record says
29 tornado tracks have crossed Morrison County since 1954 by NOAA's count, roughly one every 2.6 years - the Elevated band on this site's scale. That is the 68th percentile nationally for tornado frequency. Among 87 Minnesota counties in this dataset, Morrison County ranks 32 for how often a tornado touches down.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Morrison County in NOAA's 76-year database. Of its 29 recorded tracks, 24 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 Morrison County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
34,520 people live in Morrison 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 Morrison County's figure does not tell you
Morrison County's figure is county-wide, not address-specific. Morrison County covers about 1,125 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. Morrison County has about 34,520 residents.
