Sullivan County, PA: what NOAA's tornado record says

Against the rest of the country, that is the 35th percentile for frequency. Among 67 Pennsylvania counties in this dataset, Sullivan County ranks 39 for how often a tornado touches down.

Paying for it, if Sullivan 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
Tornado outbreaks routinely knock out power across Pennsylvania for days, separately from any single house getting hit. A portable battery bank keeps a fridge, phone chargers and a radio running through that gap - cheaper and faster to set up than a generator.
County-level, not address-level
Treat this as a county-wide figure, not a prediction for one address. Sullivan County covers about 450 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. Sullivan County has about 5,927 residents.
