How Likely Is a Tornado in Lehigh County, PA?
How likely is a tornado in Lehigh County, PA?
Lehigh County has recorded 16 tornado touches in NOAA's 76-year database, a rate of roughly one every 4.7 years - our Moderate band. Put another way: Lehigh County sees more tornado activity than 43% of US counties. Among 67 Pennsylvania counties in this dataset, Lehigh County ranks 25 for how often a tornado touches down.
Beyond the frequency band: violent history
13 weak and 3 significant tornadoes make up Lehigh County's 16-track record - none violent. NOAA has never logged an EF4 or EF5 crossing this county.
The dollar figure Lehigh 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
A direct hit is not required for Lehigh 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.
What this number is, and is not
One caveat before relying on Lehigh County's number: it is county-wide, and it covers about 345 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. Lehigh County has about 385,655 residents.
