A semi-discrete supercell thunderstorm began to exhibit rotation
over Delaware County, PA around 5:15 PM on September 1. The
rotation continued north-northeast into Montgomery County, and
eventually strengthened enough to produce a tornado. Minor tree
damage was first observed along Stenton Ave in Fort Washington in
the area of the Philadelphia Cricket Club. A path of tree damage
was observed heading northeast along Joshua Rd and through Fort
Washington State Park. Some minor shingle and siding damage to
houses was also seen.
Damage became more severe after the tornado crossed the
Pennsylvania Turnpike. At this time the tornado also moved into a
more residential area. Damage was observed along Montgomery Ave,
Spring Ave, and Prospect Ave and numerous crossing streets of
those. This mainly consisted of numerous snapped and uprooted
trees with minor to moderate roofing and siding damage to a number
of homes. The worst damage was observed slightly farther
northeast in the area of Stuart Creek in Upper Dublin. A number of
homes suffered partial to near total loss of roofing with many
damaged to the point of being uninhabitable. At least one home
experienced partial collapse of exterior walls consistent with EF2
tornado damage. Nearly all trees were snapped or heavily damaged
in this area as well.
Damage continued along Route 309 to the area of Upper Dublin High
School. The high school itself suffered roofing damage, and
significant roofing loss occurred to an Upper Dublin Township
building adjacent to the high school. A number of residences along
Loch Alsh Ave and several surrounding streets were also damaged.
A woman was killed when a tree fell on her home on Kenyon Dr, the
only known tornado-related fatality from this tornado or any
tornado during this regional outbreak.
Further northeast, damage occurred on and around the Temple
University Ambler Campus, again consisting of considerable tree
damage and partial roofing loss on a number of homes and
university buildings. The tornado then moved into Maple Glen,
crossing a heavily developed area near Norristown Rd at Limekiln
Pike. Snapped trees and mostly minor roofing and siding damage to
several commercial buildings was observed in this area. The
tornado remained continuous but did begin to lose some intensity
as it moved into Horsham Twp, traveling east of Limekiln Pike. A
number of trees were snapped along Babylon Rd. Near Horsham Rd,
roofing damage occurred to a veterinary hospital, along with
additional large trees snapped. Damage appeared to end not long
after that point. The tornado crossed Horsham Rd, but little to no
damage was observed in a couple of parks across the road,
approaching the Bucks County line. The tornado is believed to have
lifted in that area.
End.
