Tornado Risk in DeKalb County, IN
DeKalb County, IN: what NOAA's tornado record says
13 tornado tracks have crossed DeKalb County since 1968 by NOAA's count, roughly one every 5.8 years - the Low band on this site's scale. That is the 36th percentile nationally for tornado frequency. Within Indiana alone, DeKalb County ranks 74 of 92 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in DeKalb County in NOAA's 76-year database. Of its 13 recorded tracks, 10 were weak (EF0-1) and 3 significant (EF2-3).
Shelter and safe-room economics
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally (around $7,645 typical). Indiana's Indiana Department of Homeland Security's Residential Safe Room Program covers 75% of an approved project, up to $5,000 - bringing a typical job down to roughly $722.5-$8,280 out of pocket, when the program is currently funded.
Power after the storm, not just shelter during it
The storm that misses DeKalb County outright can still take its power out - outbreak-scale outages across Indiana are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
What DeKalb County's figure does not tell you
DeKalb County's figure is county-wide, not address-specific. DeKalb County covers about 363 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. DeKalb County has about 44,330 residents.
