The tornado touched down along Fisher Dam Road about 800 feet north 
of the intersection with Berne Road. Numerous hardwood tree trunks 
were snapped on the western side of the road with a convergent 
debris pattern. A corn field on the east side of the road in the 
same location was damaged with stalks of corn felled in a convergent 
pattern. Further north on Fisher Dam Road, hardwood tree damage was 
noted, but it was more sporadic.

Additional damage was noted about a half-mile north of the 
intersection of Berne Road and Hill Drive, including numerous trees 
snapped on the east side of Berne Road. A little farther north, 
about 450 feet south of the intersection with Ash Road, a utility 
pole was snapped, and hardwood trees were snapped both on the 
western side and the eastern side of the road with convergent debris 
patterns noted.

There was damage on Ash Road, including a roof that was removed from 
a porch and the roof damage extended into the main roof of the house.
The roof was deposited to the east, while at the same time, a 
flagpole from the roof supports was tossed to the north. There was 
also numerous snapped hardwood trees in this area. Further east on 
Ash Road, another house had a large, healthy tree snapped. Tree 
damage was also noted on properties on the north side of Ash Road.

Further north of Ash Road, some damage occurred at the Village of 
Pleasant Hills Mobile Home community, including hardwood trees 
snapped and some cars were damaged by the fallen trees. Some 
skirting along the base of a mobile home was mostly torn off. The 
damage appeared to become more sporadic and then ended.

The National Weather Service would like to thank Mr. Lou Ruh for his 
extensive assistance with this survey, and also thanks to the 
Pennsylvania Emergency Management Agency for providing locations of 
the damage.
