Against the rest of the country, that is the 27th percentile for frequency. Among 67 Pennsylvania counties in this dataset, Columbia County ranks 52 for how often a tornado touches down.

Paying for it, if Columbia 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 Pennsylvania 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
A direct hit is not required for Columbia County to lose power - outbreak-wide outages across Pennsylvania regularly reach homes and businesses well outside the actual tracks. A battery bank covers that gap without a generator's fuel and venting needs.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Columbia County covers about 483 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. Columbia County has about 66,012 residents.
