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.

and Lewis County Emergency Services for their assistance with
