Tornado in PENDLETON, KENTUCKY

Location: GREENWOOD

Reported by: NWS Storm Survey

Damage was first observed just north of the intersection of U.S. Route 27 and Bethel Loop. This location is south of Butler and northwest of Falmouth in Pendleton County. A mobile home originally anchored into the ground at 8-10 points was tilted and briefly lifted before rolling onto its top on the east side of Bethel Loop. The three residents sustained minor injuries requiring overnight hospitalization. Debris from the mobile home was carried downwind for approximately one-tenth of a mile. The debris field remained confined to a narrow path as it tapered to the east-northeast. This seemed indicative of convergent motion associated with the circulation. There were also several 6-8 inch trees snapped immediately west of the mobile home. This is likely where the first touchdown occurred. The tornado then lifted. The next damage location was a metal barn on Ashcraft Road. The entire roof was lifted and removed from the barn. The roof measured approximately 60 feet by 30 feet and the barn was relatively new (construction within the last 10 years). The roof was carried into adjacent trees immediately northeast of the structure. There was minor damage to a smaller barn just northwest of the path center line. The homeowner also described a dock approximately 15 square feet that was pulled from its anchor and moved north-northeast across a pond toward the center line of the path. All of this damage indicated a convergent and lifting motion associated with the tornado. The tornado then lifted again, as damage was next observed along Route 609 just south of the intersection with Davis Road. One barn west of Route 609 was destroyed and a tree approximately 20 inches in diameter immediately east of the road was snapped at the trunk and fell against a residence. Debris was carried between one and two tenths of a mile to the northeast. Another barn just to the north was partially destroyed. Tornadic damage was not as conclusive at this location, but debris was confined to a narrow path likely due to convergent wind motion. A number of trees were snapped to the northeast along Davis Road. Trees ranged in diameter from 8 to 16 inches. The clearest evidence of circulation on the ground was located along Route 159 where several types of damage occurred at a residence south of the intersection with Davis Road. The roof was partially removed from the residence and some of the insulation was dispersed to the west and spattered against the west side of the house. Insulation was also spattered on trees immediately to the northwest. Heavy sections of metal fencing from a horse corral were lifted and carried approximately 50 yards to the west. Both of these debris fields were carried and deposited opposite the storm motion. A number of trees just north and south of the residence were also snapped. The tornado lifted again before touching down one last time. The final damage was found along Hickory Grove Road, south of the intersection with Route 10. This is the estimated end of the tornado path. A camper was lifted to the north-northeast approximately 10-15 feet over trees before being dropped and destroyed. There was also minor structural damage at two nearby mobile homes. This damage consisted of garage doors blown inward and some roof damage.
