Jennings County, IN: Tornado Risk and Shelter Cost
Jennings County's tornado history, by the numbers

Against the rest of the country, that is the 45th percentile for frequency. Indiana has 92 counties in this dataset; Jennings County ranks 61 of them by frequency.
Has Jennings County ever had a violent tornado?

Paying for it, if Jennings County's history says you should
Nationally, storm shelters and safe rooms run $2,890-$13,280. Because Jennings County is in Indiana, the Indiana Department of Homeland Security's Residential Safe Room Program can cut that by 75% (capped at $5,000), to about $722.5-$8,280 net - check current funding status before counting on it.
The gap a shelter does not cover
Power loss after a tornado outbreak in Indiana often reaches homes the storm itself never touched. A battery-backup unit covers the outage without the fuel and venting a generator needs.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Jennings County covers about 377 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. And records from before the 1990s, NOAA notes, undercount weaker tornadoes in areas with less storm-spotting coverage at the time. Jennings County has about 27,634 residents.
