- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Dillon County: 3.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

- The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

National Weather Service narrative
Hurricane Matthew moved up the eastern seaboard, bringing very heavy rain and strong winds. Rainfall amounts were high, with over a ten inches of rain reported. Tropical storm force winds and flooded ground caused widespread tree and power line damage. Major flooding resulted in the closure of I-95 between mile markers 181 and 193. Moderate river flooding across the southern parts of the county near the Lumber and Pee Dee rivers. Highway 9 from Dillon to Lakeview required closure. The Squires Lake Dam and Little Pee Dee state Park Dam failed due to flooding. Two main roads were closed due to flood waters, Highway 501 from Latta to Highway 9 and Highway 9 from Dillon to Little…

Winds averaged 50 mph and gusted near 70 mph across Dillon County during the evening as Hurricane Fran passed north off the coast. Combined with 6 inches or rain, widespread damage to trees, structures and agriculture resulted in more debris than was caused by Hugo in 1989. Dollar damage to homes was over $1 million. Evacuation shelters housed 800 people overnight, served 2500 meals.

National Weather Service narrative
A National Weather Service Storm Survey concluded a tornado first touched down approximately 200 yards south of Dogwood Lakes Road at 1250 AM EST. Large pine trees were snapped and a mobile home rolled about 20 yards before completely disintegrating. It is unknown how well the mobile home was attached to its foundation. A truck was flipped in a church parking lot on Goings Drive. No injuries were reported. The damage was indicative of winds of 110 to 120 mph, EF-2 on the Enhanced Fujita Scale. The path width was approximately 40 yards. The tornado touched down for a second time resulting in near total roof failure and some damage to the exterior walls of a brick home on Pee Dee…
