No damage could be seen west of the interstate, creating the initial damage to a carport at the business, then cutting an approximately 50 yard path through the middle portion of the second storage shed on the property. The tornado moved northeast, depositing several pieces of sheet metal and wood onto Old Route 66 and fields to the east. Despite visible power flashes in videos, power lines looked untouched. A house, two farm buildings and trees were damaged on the south side of Tall Timber Road. Another structure to the north side of Tall Timber Road, at the end of Adden Road, was also damaged.
