Summary:

The National Weather Service in Binghamton, NY has confirmed a Microburst/Straight line wind damage near Hancock in Delaware county New York on April 19, 2013.

Straight line wind damage was observed on Stockport Road just south of the village of Hancock in Delaware county. Strong straight line winds associated with a thunderstorm rapidly descended the western aspect of a hill leading down to the south branch Delaware River. At this location, multiple uprooted or snapped trees were found lying in a west to north fanning orientation. As a result of all trees laying in a similar path, and no evidence of a cyclonic circulation extending to the ground, the damage is consistent with straight line wind damage of roughly 80-85 mph.

Summary:

The National Weather Service in Binghamton, NY has confirmed a Microburst/Straight Line wind damage in Auburn Township along Rowe Road in Susquehanna county Pennsylvania on April 19, 2013.

At this location, strong straight line winds on the order of 100 to 110 mph caused extensive damage to two outbuilding type structures composed of wood framing and tin siding. Strong winds hit the first structure causing nearly complete destruction, with wood framing and tin siding blown directly towards the north-northeast down Rowe Road. Winds then hit the second structure with remnant tin siding and attached roof framing blown directly east across Route 267 into an adjoining field and wooded area. As with the first outbuilding, strong winds caused nearly complete destruction of the second metal-framed building. With the damage pattern extending in a fanned out pattern from location of initial structural damage, the above evidence supports strong straight line wind damage at this location.

Reference: 

A microburst is a convective downdraft with an affected outflow area of less than 2 1/2 miles wide and peak winds lasting less than 5 minutes. Microbursts may induce dangerous horizontal/vertical wind shears, which can adversely affect aircraft performance and cause property damage. Straight-line winds are generally any wind that is not associated with rotation, used mainly to differentiate them from tornadic winds.
