How Likely Is a Tornado in McKean County, PA?
How likely is a tornado in McKean County, PA?
McKean County has recorded 5 tornado touches in NOAA's 76-year database, a rate of roughly one every 15.2 years - our Minimal band. Put another way: McKean County sees more tornado activity than 16% of US counties. Among 67 Pennsylvania counties in this dataset, McKean County ranks 63 for how often a tornado touches down.
Beyond the frequency band: violent history
1 tornado touching McKean County reached violent (EF4-5) strength since 1950. That single fact carries more weight for the shelter decision than the county's overall frequency band.
The dollar figure McKean County's rating leads to
Cost nationally: $2,890-$13,280, about $7,645 typical. Pennsylvania has no state rebate program confirmed here; FEMA's underlying 75% cost-share exists nationwide, but applying through a state program is what usually makes it real, and none was found for Pennsylvania this pass.
What a direct hit isn't required for
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.
What this number is, and is not
One caveat before relying on McKean County's number: it is county-wide, and it covers about 980 square miles, so a single touch counts the same as one in a county a fraction of that size. Weaker pre-1990s tornadoes are also documented as undercounted in NOAA's own record. McKean County has about 39,478 residents.
