With coordination and assistance from the Emergency Management Agencies
in Butler and Montgomery Counties, the National Weather Service in Wilmington
confirmed a brief and weak EF1 tornado that touched down Friday evening in
extreme southwest Montgomery County southeast of Gratis, and lifted in
northwest Butler County southwest of Germantown.

The tornado initially touched down on the west side of Puddenbag Road south
of Barlow Road and damaged several groves of trees before crossing Puddenbag
Road and snapping and uprooting several more groves of trees on the east side
of Puddenbag Road.  The tornado crossed in front of a farmstead and snapped and
uprooted a number of trees in front of the residence. It was at this location
where tree damage was estimated to be caused by winds in the 90-95 mph range.
The tornado continued southeast to Oxford Road where roofing material was lifted
from a home on the north side of the road, and a barn on the south side of the
road, while also continuing to cause considerable tree damage. The tornado then
continued southeast across Elk Creek Road toward No Mans Road where more tree
damage was found. In this location the damage was found to be considerably more
broad and of lesser intensity, suggesting the tornado was lifting as it moved
south along Elk Creek Road and No Mans Road.

Damage was clearly tornadic in nature, with the damage path found to be quite
concentrated and convergent in nature, with a number of tree branches lifted
and thrown considerable distances downstream (several hundred yards or more
at times).  The worst of the tree damage was consistent of wind speeds estimated
between 90 and 95 mph, making this a low-end EF1 tornado.

The National Weather Service wishes to thank the Butler and Montgomery County
Emergency Management Agencies for their continued support and assistance.
