The tornado then crossed Highway 599 where an antenna was collapsed, many large hardwood trees were snapped and uprooted and all were blown to the northeast. A shed building roof was also collapsed at this location. The tornado was at its widest, around 300 yards wide, near this location. It continued east-northeast before hitting a house near the intersection of Highway 599 and Homer McDaniel Road. Here roof damage occurred, tin was blown around, a large metal and PVC tank were blown over. A few large cypress hardwood trees were snapped and blown across the road. It then crossed Homer McDaniel Road where a tree was snapped then crossed near Horace Hill Road where a power pole was broken near the base. The tornado continued east-northeast briefly in the field before lifting.
The National Weather Service in Jackson would like to thank the University of Louisiana-Monroe meteorology department for providing data from the new Monroe radar for this tornado event. The damage survey for this tornado was prompted by a tornadic debris signature in the provided radar data. We look forward to forging a continued relationship with ULM meteorology department into the future.
