Clark County, MO: Tornado Risk and Shelter Cost
Clark County, MO: what NOAA's tornado record says
NOAA's Storm Prediction Center has recorded 16 tornado tracks touching Clark County since 1954 - about one every 4.7 years on average. That puts it in our Moderate band nationally. Against the rest of the country, that is the 42nd percentile for frequency. Among 115 Missouri counties in this dataset, Clark County ranks 90 for how often a tornado touches down.
Has Clark County ever had a violent tornado?
Nothing violent in Clark County's file: 16 tracks total, topping out at significant (EF2-3) strength on 5 of them, zero at EF4-5.
Paying for it, if Clark 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 Missouri 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 Clark County outright can still take its power out - outbreak-scale outages across Missouri 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. Clark County covers about 505 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. Clark County has about 6,623 residents.
