Survey Summary:

An NWS storm survey in conjunction with Washington County Emergency
Management concluded that an EF-1 Tornado touched down, and was
embedded in a larger field of straight-line winds. The tornado may
have been an extension of the Lawrence/Orange County EF-2(1), and
further work is being done to confirm the extension of the path.
Preliminary path length is 5 miles with a max width of 100 yards for
the tornado, however the overall straight line wind path width was
close to a mile wide in spots. The most intense tornado damage
happened shortly after touchdown where over 50 healthy hardwood
trees had snapped trunks with no foliage. In addition, an
outbuilding lost part of a roof, and debris struck a residence
causing cracked masonry and dented drywall on the inside of the
structure. Maximum wind speeds of 100 mph were estimated in the
area. The tornado continued eastward where more homes experienced
minor roof damage, trees were uprooted, and a large outbuilidng was
nearly destroyed. After crossing Cave River Valley Rd and White
River Rd, the tornado took out nearly 50 softwood trees. Further
east, over 100 hardwood and softwood trees were uprooted and
snapped, and notable convergence was observed. After driving a 4 X 6
post through the roof of a home near Hunter Rd, the tornado
continued east to Prowsville Ridge Rd where an uptick to 90-95 MPH
intensity was noted. Another stand of nearly 50 hardwood trees were
uprooted and snapped, along with significant damage to a porch and
roof of a home. Tornadic damage ceased east of Cox Ferry Rd, however
some instances of straight line winds were noted all the way to
Delaney Park Rd. It was also noted that straight-line winds were
surveyed south of the tornado damage path from Saltillo eastward to
West Washington School Road. Eyewitness accounts put this damage at
slightly earlier times than when the tornado damage occurred. The
straight-line wind damage ranged from 60 to 80 mph.

EF Scale:  The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak.....65 to 85 MPH
EF1...Weak.....86 to 110 MPH
EF2...Strong...111 to 135 MPH
EF3...Strong...136 to 165 MPH
EF4...Violent..166 to 200 MPH
EF5...Violent..>200 MPH

Note:  The information in this statement is preliminary and subject
to change  pending final review of the event and publication in NWS
