Summary

The National Weather Service in Binghamton, NY confirmed a tornado near Honesdale in Wayne county Pennsylvania on July 23, 2010.

This was the third and most significant tornado touch down from the storm. The damage path begins three miles northeast of Honesdale. Significant tree damage occurred. 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. Here, winds were estimated to peek in the 110 to 120 MPH range putting it at the lower end of an EF2.

The tornado continued to the southeast destroying trees on the west side of Williams Pond and Mud and Open Woods Ponds and then crossing into Pike County. It moved past Wolf Lake, Teedyuskung Lake, and Fawn Lake still doing EF1 damage to trees. The path begins to narrow and oscillate between EF0 with little damage to EF1 with trees snapped and uprooted. It crosses Route 590 (twice) and the Lackawaxen River east of Rowland and appears to dissipate over State Game Lands about 2 miles northeast of Greeley.

The National Weather Service in Binghamton, NY confirmed a tornado near Hawley in Wayne and Pike Counties Pennsylvania on July 23, 2010.

Summary

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 and another two miles of damage in Pike County crossing the north end of Tinkwig Lake. Again the damage is 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 estimates 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 the downburst.

The National Weather Service in Binghamton, NY confirmed a large downburst from 1 mile northeast of Hawley in Wayne County to 2 miles southeast of Greeley in Pike County Pennsylvania on July 23, 2010.

Summary

Radar indicated the development of a very strong downburst (macroburst) 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. Amazingly, no one was hurt.

Additional Wind Damage from the Storm in Susquehanna, Wayne and Pike Counties

Scattered wind damage, mostly to trees, was observed outside of the main damage paths documented above. Isolated trees were reported down across Susquehanna County from near Brackney to near New Milford, Gibson, and areas east. Likewise, isolated trees were down in Wayne County near Waymart, White Mills down to Hawley and through Pike County. The most significant impact was in Honesdale were a sidewalk sale was occurring. Strong winds blew down the main business district and rapidly tore up a dozen or so tents on the sidewalks. Heavy rain accompanied the storm causing minor street flooding in Honesdale.
