Tropical Depression Debby slowly made its way through Florida, off the South Carolina coast, then back inland through the western Piedmont of North Carolina during the evening hours of 8 August 2024. Ahead of the storm, numerous feeder bands brought periods of heavy rain to central North Carolina, resulting in widespread 4-6 inch rainfall amounts across the western Piedmont, with higher amounts to the east. In addition, numerous tornadoes occurred with this event, with one on 7 August and an additional 6 on 8 August including a rare EF-3 tropical cyclone tornado.

A tornado briefly touched down at the Rocky Ford Community of Franklin County, NC. Several softwood trees were snapped and uprooted, and one utility pool was snapped. A well-defined tornado debris signature was noted on radar at the noted time.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
