Tornado Risk in Oconto County, WI
How likely is a tornado in Oconto County, WI?
16 tornado tracks have crossed Oconto County since 1966 by NOAA's count, roughly one every 4.7 years - the Moderate band on this site's scale. That is the 43rd percentile nationally for tornado frequency. Within Wisconsin alone, Oconto County ranks 50 of 72 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Oconto County in NOAA's 76-year database. Of its 16 recorded tracks, 9 were weak (EF0-1) and 7 significant (EF2-3).
Shelter and safe-room economics
Wisconsin does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Oconto 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 Wisconsin often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
What Oconto County's figure does not tell you
Oconto County's figure is county-wide, not address-specific. Oconto County covers about 997 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. Oconto County has about 40,037 residents.
