Survey Summary:
The National
Weather Service in Buffalo completed a damage survey
across Lewis
County today in response to numerous damage reports
across the county
from a line of severe thunderstorms yesterday,
June 30th.
As a result of
this survey, the National Weather Service found a
few areas of
concentrated damage. This second area was determined
to be caused by
an EF-1 tornado with maximum wind speeds in the
range of 95 to
105 mph. The damage occurred right around 2 pm
local time across
almost a 3/4 mile stretch of Swiss Road midway
between
Castorland and Croghan. The track of the tornado almost
paralleled the
road in this stretch, but did cross at some point as
it traveled in a SSE direction. Convergent damage was noted along
several points,
as well as a generally chaotic nature to tree
damage near
Widmeyer Creek. With only a couple of structures in
this area, most
of the damage was to trees, but the tree damage
was severe in
some spots along the damage path. Additionally,
several
power poles and lines were taken down, either
by the tornado
itself or from
falling tree and limbs.
The National
Weather Service extends its thanks to local media
and Lewis County Emergency Services for their
assistance with
today`s survey.
