Sunday tornado confirmed at Bucks County campground; Pa. exceeds annual twister average
It wasn’t much, and it didn’t last long, but National Weather Service investigators have confirmed that a tornado touched down Sunday at the Beaver Valley Campgrounds in the Ottsville section of Tinicum Township, Bucks County.
![Pennsylvania tornadoes by county in the last 70 years. The state already has exceeded its annual average for twisters this year.](https://www.inquirer.com/resizer/v2/3C7KOY4UHBFR3N7N6XZ2QL5RV4.jpg?auth=320a451bba4d718f61baa5455ca410e5725c28a02d8adeeaaf7026feb99b878a&width=760&height=507&smart=true)
The National Weather Service on Thursday confirmed that a weak tornado — no injuries were reported —touched down on Sunday at the Beaver Valley Campgrounds in Bucks County.
The weather service said an EF-1 tornado, with peak winds of 95 mph, swirled through about a quarter-mile of the property in the Ottsville section of Tinicum Township. It stayed on the ground for about a minute, the weather service said, and “dozens of trees were uprooted.”
With the sightings in Bucks and another in Lancaster County on Sunday — which the weather service said came “very close” to the Pennsylvania Turnpike — 16 tornadoes have been confirmed in the commonwealth this year; the average for an entire year is eight.
The Lancaster County twister, which touched down near West Cocalico Township, was also an EF-1, but the winds were slightly friskier — 105 mph. It uprooted dozens of trees and caused some minor damage to mobile homes.
Investigators determined that damage was caused by rotating winds, rather than in a “straight line.”
It isn’t as though circular winds are somehow more ferocious, but the investigators are motivated by a mix of the public’s curiosity and science. It is one way the weather service keeps track of “false-alarm rates” for tornadoes, the object being to get better at this.
Correction: An earlier version of this version is this story listed an incorrect number of total tornadoes this year in Pennsylvania.
Currently, about 75 percent of all tornado “warnings” are false alarms.
