...Summary...
The National Weather Service in Wilmington OH has confirmed a
tornado near 3 WSW Octa in Fayette County Ohio on May 24 2017.

Based on radar data, video evidence and eyewitness reports, the
tornado appeared to first touch down about 3 miles WSW of Octa in
extreme western Fayette County. The tornado then moved northwest
into far eastern Greene County, appearing to make occasional
contact with the ground, before dissipating about 4 miles
southeast of Jamestown.

As the tornado moved through primarily empty farm fields, there
was little in the way of damage found. Therefore, maximum winds
were estimated to be 50 MPH, equivalent to a weak EF0 tornado.

For reference: the Enhanced Fujita Scale classifies tornadoes
into the following categories:

EF0...wind speeds 65 to 85 mph.
EF1...wind speeds 86 to 110 mph.
EF2...wind speeds 111 to 135 mph.
EF3...wind speeds 136 to 165 mph.
EF4...wind speeds 166 to 200 mph.
EF5...wind speeds greater than 200 mph.
