Humphreys County, TN: Tornado Risk and Shelter Cost
Humphreys County, TN: what NOAA's tornado record says
NOAA's Storm Prediction Center has recorded 26 tornado tracks touching Humphreys County since 1952 - about one every 2.9 years on average. That puts it in our Elevated band nationally. Against the rest of the country, that is the 62nd percentile for frequency. Among 95 Tennessee counties in this dataset, Humphreys County ranks 20 for how often a tornado touches down.
Has Humphreys County ever had a violent tornado?
Yes, 1 time: Humphreys County has an EF4-5 tornado on record. Wherever that history exists, FEMA's safe-room case applies regardless of how often the county gets touched overall.
Paying for it, if Humphreys County's history says you should
A storm shelter or in-residence safe room typically runs $2,890-$13,280 nationally, around $7,645 for a common single-family installation. No state-administered rebate program specific to Tennessee was confirmed for this site - FEMA's own Hazard Mitigation Assistance grants fund 75% of an approved safe room nationwide, but only some states currently run a homeowner-facing application on top of that.
The gap a shelter does not cover
The storm that misses Humphreys County outright can still take its power out - outbreak-scale outages across Tennessee are common well beyond the tracked path. A battery-backup unit handles that without a generator's setup or fuel.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Humphreys County covers about 531 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. Humphreys County has about 19,554 residents.
