Winds reached 100 mph along its 3 mile long and 125 yard wide path.  The storm cut a very narrow path through trees immediately west of KY 79 near Gracie Lane, with a number of trees snapped and uprooted.  One of the trees along Gracie Lane fell on power lines, tearing them down.  Metal roofing on a barn was blown off and pushed a few hundred yards downwind into the woods.  A small well-constructed shed was pushed over onto its side, and another small shed was destroyed.  In addition a nearby house had its metal roof blown off.  The tornado may have begun to skip intermittently through some woods east of KY 79 as only a few trees lost some limbs near the intersection of Delmar Lindsey Lane and Lawrence Hayes Road.  However, just to the east of this location, along Coats Road, a metal outbuilding was destroyed consistent with EF-1 damage.
