An EF-1 tornado began in West Caln Township near Baldwin Road where a hardwood tree was uprooted and found hanging on top of downed wires. South of here, between Baldwin Road and Chantry Lane, another hardwood tree was found snapped at its trunk. This was the area that the tornado reached its maximum width of approximately 250 yards. The tornado then continued eastward with tree and wire damage seen on North Sandy Hill Road near Wallace Lane where a tree and large limbs fell on and damaged a wooden fence. Continuing further east, a row of hardwood trees was severely damaged with snapped trunks on Martins Corner Road just north of Wagontown Road. A utility pole was also snapped here, but this appeared to have been caused by the falling trees and the strain introduced to the wires since the pole may have been weakened by age. The tornado then dissipated as there was no concentrated damage found east of Martins Corner Road. Additional damage separate from this path was noted and appeared to be caused by straight line winds. This includes tree damage in the Hidden Acres Campground on the northwest side of Baldwin Road.
