Monday's storm downed a tree between 294 and 298 Ridge Road, between Adams and Valencia Townships.

Weather experts said a tornado touched down Monday afternoon in Pine Township, Allegheny County near its border with Butler County.

“It was a fairly weak tornado,” said Lee Hendricks, a meteorologist with the National Weather Service of Pittsburgh. “At its maximum, the width of the path was about 50 yards wide.”

The service said the tornado was an EF0, which has winds of 65 to 85 miles per hour. Hendricks said the maximum windspeed for this tornado was around 70 mph.

According to the service, no injuries or deaths were reported due to the tornado.

A Weather Service news release stated the tornado touched down at 2:55 p.m. Monday in the 800 block of Mt. Pleasant Road in Pine Township, just south of the Seven Fields and Cranberry Township areas.

The touchdown site was about three miles southwest of Seven Fields, so close to the border that residents along that road have a Mars mailing address.

The end point, about 1.2 miles from the start, was around the 400 block of Warrendale Road, Pine Township. In its wake, it left mostly debris from damaged hardwood trees.

“The hardest hit area was near a playground by the entrance to the Emerald Fields Housing Development,” the release said. “This is where six trees were uprooted.”

Hendricks said the tornado originated from the ideal conditions, a cold front.

“It's most commonly found at the head of a cold front,” he said. “That's usually where you get the strongest turning of the winds and the most lift off the humid air.”

Allegheny County last saw a tornado April 8, which was also rated an EF0 and touched down in a remote area. This is the 18th documented tornado for Allegheny County since 1882.

According to Weather Service records, the last tornado to hit Butler County was in 2019, rated EF1. There have been 24 recorded tornados that touched down in Butler County since 1950.

According to the service, the worst tornado to strike the county since 1950 was an EF3 tornado in 1985 that ripped through both Butler and Beaver counties.
