   "description": "The first evidence of tornadic damage was observed at the Pierce Reserve & Trails on Pond Run Road, where numerous large tree limbs were knocked down. The tornado strengthened as it moved southeast onto Mott Road, where roof damage was observed at a two story home along with numerous trees being snapped in an adjacent wooded area. Winds in this area were likely near 90 mph, which corresponds to EF-1 on the Enhanced Fujita Scale. Tree damage was common and in a very convergent path along Fagins Run Road and Wilson Dunham Hill Road. While damage became more sporadic farther southeast, additional tree damage within the convergent tornadic path was reported at a residence on OH-132 and Wildfire Way. Large tree limbs were also knocked down along New Richmond Nicholsville Road, and this is where this tornado appears to have ended. The National Weather Service would like to thank the Clermont County Ohio Emergency Management Agency and Pierce Township Fire Department for their assistance with this storm damage survey.",
