In the southeastern corner of the county, the damage path began as a thin, barely discernible strip of broken branches and limbs along Route 948. Within minutes, it had transformed into a nearly mile-wide swath of utter desolation. The tornado very quickly reached what may have been its peak intensity as it moved into the Tionesta Scenic Area, where it produced what one former Forest Service official called “the most complete destruction of forestland” he’d ever seen.
Violent winds rushed inward toward the heart of the vortex, dislodging and splintering entire tracts of old-growth forest. Even mature sugar maples, known for their robust wind-resistance, were cut down with ease. Trees fell in a distinct convergent pattern, with those along the line of convergence toppling in the opposite direction of the tornado’s travel — a signature only seen in the most violent of storms. Researchers studying the tornado’s devastating impact on the Tionesta Scenic Area later estimated that more than 99% of trees within the damage path were either broken or uprooted.
