The National Weather Service in Binghamton, NY has confirmed a
microburst /straight line wind damage/ near Tunkhannock in Wyoming
County Pennsylvania on 7/29/2009.
- Location - Tunkhannock In Wyoming County Pennsylvania
- Date - 7/29/2009

Numerous trees were both uprooted and snapped first starting on
Rogers road. The damage path continued southwest, with all of the
trees pointing in the same direction. The damage path crossed near
a house on Jenks road before ending across the road in an area of
trees. The determination of the wind speed was based on the fact
that while most of the trees were uprooted, being aided by the
very moist ground, enough trees were snapped. This is suggestive
of estimated wind speeds between 80-85 mph.
The National Weather Service Binghamton extends their appreciation to the Wyoming County Emergency Management Agency
for their help in conducting the storm survey.
- 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.
