Reported by: Emergency Manager

The National Weather Service in conjunction with Spencer County Emergency Management conducted a damage survey near Highway 44 and Carl Monroe Road 2 to 3 miles west of Taylorsville. The survey found a narrow path of straight line wind damage with estimated winds between 75 and 85 MPH. The most significant damage occurred at the path start on Carl Monroe Road where the second level of a cinder block farm building was removed. Roofing material and cinder block debris was scattered to the ENE 100-200 yards downwind. A two-story home also suffered damage in this area with the removal of siding, soffit, and shingles. Debris shattered a window, and a dead-bolted door was blown open after the storm door was ripped off. Several large limbs were ripped out of a tree and tossed across Carl Monroe Road.
Wind damage continued east while paralleling just south of Highway 44 where 3 more hardwood trees were broken or uprooted. Several large hardwood trees were uprooted in the Elk Creek Bottom. Continuing east, wind took shingles off of a home and damaged several trees. Damage ceased 2 miles west of Taylorsville with a final downed tree along Highway 44.
The event lasted 1 to 2 minutes and occurred on the leading edge of a gust front. Many residents noted that no rain was occurring at the time of the event, bur rain started a few minutes later. This matches the radar presentation. All debris was scattered in a divergent ENE to NE direction.
