The tornado then moved northwest, causing damage tothe Applebees sign, and then turned west and impacted the Arbys.This was the location of the strongest damage as numerous windowswere blown out at the Arbys on both the west and east-facingsides of the building. The rooftop A/C was also blown into theArbys parking lot. However, no other structural damage wasnoted, and therefore the degree of damage was kept near themiddle of the expected wind speed, or at 95 mph. The WalmartSupercenter to the northwest of Arbys also sustained some veryminor roof fascia damage, which was starting to peel off from themain structure. After this, the tornado continued to movenorthwest and passed Mitton Road, where several trees wereuprooted with a few branches greater than 3 inches diameter broken.There was also a residence on Mitton Road that had roof damage toless than 20% of the structure.
