A warm front lifted north into northeast Pennsylvania during the afternoon, putting the area into the warm and moist air mass of the warm sector, with temperatures in the mid 80s and dew points in the 70s. Showers and thunderstorms developed in the vicinity of the front in this unstable air mass. Stronger storms developed across southeast Susquehanna county, with one storm in particular developing strong rotation as it moved southeast into Wayne county. This storm went on to produce four tornadoes and other significant microburst damage as it continued southeast through Wayne and into Pike county.

Location: WHITE MILLS
Tornado F-scale: EF1
Property damage: 20.00K

Reported by: NWS Storm Survey

This tornado is believed to be a smaller spin-up tornado on the edge of a developing strong rear flank downburst from the storm. It occurs at the same time as the other more significant, long track tornado. A narrow concentrated path of damage through trees was observed. About two miles of damage occurred in Wayne County, all of which was to trees.

Crop damage: 0.00K
Reported by: NWS Storm Survey

This is a continuation from a tornado that tracked southeast from Wayne county. Another two miles of damage from this tornado was observed in Pike County, crossing the north end of Tinkwig Lake. The majority of the damage seen was to trees, but large fallen trees damaged a few homes and destroyed one, cutting it in half. This was a heavily wooded residential area. Trees also took down power and telephone poles and lines. Winds with this tornado were estimated at 70 to 90 mph. While it is possible that the path is longer, it became very difficult to differentiate the damage from the tornado and the increasingly significant damage that occurred from downburst winds.

Trees fell on an attached garage on Torrey Road. Barn roofs were peeled. The tornado intensifies as it moved along Dunn Road. Trees are snapped, uprooted and thrown in what appears to be two separate paths through dense woods indicating mulit-vortex. Several structures had damage from fallen trees. A fence was pulled out of the ground and strewn in different directions. The greatest damage occurred about 4 miles east of Honesdale and 1.5 miles west of Beach Lake where Dunn Road meets Route 652. Several structures were severely damaged or destroyed including a triple-wide trailer, two barns, and a commercial auto transmission business on Route 652.

Thunderstorm Wind in PIKE, PENNSYLVANIA

Location: LACKAWAXEN
Magnitude: 70.00 EG
Property damage: 50.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

Radar indicated the development of a very strong downburst on the rear flank of the tornadic supercell. The damage was a very large area and more profound in its scope of damage than the tornado paths in Pike County. The peak winds were estimated at 70 to 90 mph where large swaths of trees were uprooted and snapped. Large trees fell on roads, power and phone lines, took down poles, and damaged some homes. One truck was smashed in half and a home was demolished by large trees. A significant amount of trees came down along the Lackawaxen River. Most of the trees were fallen to the southeast, except along the Lackawaxen where the river valley deflected the winds and trees fell to the east. Hundreds of people were impacted by the storm as power was out for a couple days in some locations and roads were closed until trees and fallen power lines could be cleared.
