...Summary...
The National Weather Service in Charleston WV has confirmed a
Microburst near Despard in Harrison County West Virginia on June
23, 2017.

Damage from this microburst began on the crest of a ridge near
Beechnut St. in the community of Despard. Initially, tree damage
was more sporadic with a couple of trunks snapped and large limbs
broken out of the tops of trees. On the downwind side of this
ridge, at least three large trees were uprooted. Also, one large
tree was snapped several feet above the ground. The orientation of
the felled trees clearly indicated a divergent pattern commonly
seen in microbursts. Shingles were peeled off the roof of a house
along Beechwood Ave. and some trees behind this house were either
snapped or uprooted as the microburst began to crest a second
ridge between Beechwood Ave. and Beech St.

The most impressive damage occurred along the crest of this
ridge, between Beech St. and Highland Ave. One house had
approximately half of its shingles removed and multiple large
trees behind it were snapped and/or uprooted with full exposure of
root balls, each with extensive, deep root networks. This is
likely where the highest observable winds occurred with this
microburst, with maximum speeds of at least 100 MPH. Damage then
became very sporadic, consisting of small snapped limbs.

The National Weather Service in Charleston, WV would like to
sincerely thank Harrison County Emergency Management and the
public for reporting and helping survey damage from Friday`s
storm.

For 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 and
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.
