Paying for it, if Harrison 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 West Virginia 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
64,472 people live in Harrison County, and a tornado outbreak's power loss usually reaches far more of West Virginia than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Harrison County covers about 416 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. Harrison County has about 64,472 residents.
