Tornadoes

Tornado - CUMBERLAND CITY CLINTON COUNTY, KENTUCKY Date Feb. 28, 2021 Time (Local) 9:18-9:22 PM EST EF Rating EF1 Est. Peak Winds 110 mph Path Length 3.6 miles Max Width 75 yards Injuries/Deaths 0/0 Summary: The National Weather Service in conjunction with Clinton County Emergency Management conducted a storm damage assessment survey. The initial tornado touchdown was on the western edge of Cumberland City, approximately 5 miles northeast of Albany.  There were several snapped trees along with roofing damage at several homes, before more extensive structural damage occurred at 5250 Hwy 558. Several large barns were destroyed or had at least 70% of the walls blown out. A brand new 64 x 56 large brand new (1 month old) constructed barn with 6 foot footers in concrete was totally destroed. The debris from the barn was thrown over a quarter-mile down wind to the northeast. Another 60 by 43 barn that had recently been remodeled and upgraded had three walls blown out. A Kubota UTV weighing 2500 pounds was moved 30 yards and rotated 180 degrees. There was also extensive snapping and uprooting of trees. Winds were estimated to be 110 mph. Farther northeast, a large 50 x 60 barn was destroed and debris went at least a half mile down wind. A mobile home along Hwy 829 was lifted off its foundation, and there was several trees uprooted and snapped. The tornado crossed 829 and then crossed 1009 with extensive tree damage along both sides of the road. A large barn on 1009 had two walls blown out with debris thrown over a half a mile downwind and was thrown into Wayne county. The tornado continued into far western portions of Wayne county. We would like to thank Clinton County emergency management director Lucas Abner, for his assistance with the survey along with Dr. Bill Fountain, Extension Specialist from the University of Kentucky Extension.
