Anderson County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Anderson County: 0.
2. 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.

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

Smoke overhead

1. 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.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. 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.

Every earthquake of magnitude 4 or more within 50 miles

1. 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).
2. 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).

1. Dec 4, 2002Ice Storm, Anderson$11.0 million
   National Weather Service narrative

   Freezing rain began across upstate South Carolina during the early afternoon of the 4th, and had spread into the eastern piedmont by mid afternoon. Resultant damage due to ice accumulation began during the mid-to-late afternoon. The intensity of the freezing rain increased after midnight, and by dawn on the 5th, devastating ice accumulations of 1/2 to 1 1/2 inches were observed, with the hardest hit areas being along the I-85 corridor, from Anderson, to Greenville-Spartanburg, to Gaffney. Hundreds of thousands lost power, and the outages lasted for as long as 2 weeks in some areas.

2. Sep 27, 2024Tropical Storm, Anderson$7.0 million
   National Weather Service narrative

   Thousands of trees were blown down, with dozens of trees down on homes, vehicles, and power lines. Frequent gusts up to 70 mph occurred, with occasional gusts of 80 mph.

4. Sep 16, 1996Tornado$3.0 million
5. Jan 2, 1999Ice Storm, Anderson$1.5 million
   National Weather Service narrative

   A shallow cold arctic airmass in place ahead of a developing storm system in the southern Plains set the stage for a significant ice storm for most of the Upstate during the evening of the 2nd. Patchy sleet began during the late morning and became more widespread and heavier during the afternoon - mixing at times with freezing rain. Sleet accumulated to nearly one inch across the foothills before changing to freezing rain in the early evening. Freezing rain continued through the evening, heavy at times and accumulated to damaging levels. Downed trees and power lines caused widespread power outages, totalling 160,000 across the Upstate. Much of the damage to homes was due to ice…

6. Jul 4, 2001Thunderstorm Wind$1.5 million
   National Weather Service narrative

   A trained spotter measured a wind gust to 58 mph. Lightning struck a church in the Cheddar community, between Williamston and Belton. The resulting fire destroyed the main building.

   Severe thunderstorm winds caused damage to some buildings at the county fairgrounds, resulting in postponement of a bingo tournament. Roofs were blown off three buildings.

10. Feb 6, 2020Flood$500,000
    National Weather Service narrative

    Although heavy rainfall steadily tapered off across the area through the afternoon into the evening, flooding continued along the Eighteen Mile Creek and Saluda River basins into the evening, with major flooding developing along the Saluda in the west Greenville by late evening. Several homes were inundated with water, including along Lakeview Dr in Powdersville, Guy St and Adger St in Pelzer. Flooding persisted along the Saluda through the 7th.
