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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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.

    National Weather Service narrative

    A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that yet a third tornado touched down in Hancock county within a 15 minute period of time. However, this tornado was determined to be an EF3 tornado. This tornado touched down about halfway between Sparta and Culverton in east central Hancock county. The tornado was determined to have a maximum path width of 1/2 mile with maximum winds of 160 mph. Much of the damage occurred along Dunn and Hickory Grove Roads. Along the path of the tornado, one 4000 square foot site-built home was completely destroyed. The debris from the home was scattered across an area up to 400 feet…

    A storm survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that an EF3 tornado touched down approximately five miles east-southeast of Sparta, or about three miles east of the intersection of Georgia Highway 15 and 16. The tornado then moved along a nearly eight-mile long path across far southeast Hancock county and continued into extreme southern Warren county and then into extreme northwest Glascock county. The total tornado path length was nearly 11 miles long. The maximum path width was estimated to be 500 yards with maximum winds of 140 mph. A church, two site-built homes, and four mobile homes were completely destroyed in…

Rainfall of six to eight inches fell across much of the county. Georgia Highway 22 and 16 were both closed. In addition, several wooden bridges were washed out.

  4. Jan 28, 2005Winter Storm, Hancock$150,000
    National Weather Service narrative

    A significant and fairly prolonged winter storm/ice storm affected nearly all of North and Central Georgia from the evening of Friday January 28th to late morning on Sunday January 30th. The winter storm was a result of a very strong and very cold Arctic surface high pressure system located across the Mid-Atlantic states and an upper-level disturbance moving across the region from the west. North of a line from La Grange, to Thomaston, to Sandersville, the precipitation fell mostly as a mixture of sleet and freezing rain, with typical accumulations of one-half inch glaze ice and one to two inches of sleet. Some areas in North Central and Northeast Georgia experienced significant…

  10. Jan 28, 2000Ice Storm, Hancock$33,000
    National Weather Service narrative

    A series of short waves in the upper air pattern produced periods of mostly light to occasionally moderate precipitation over the north half of Georgia from Friday morning to Sunday afternoon. Patchy light snow began in west central and northwest Georgia around daybreak on the 28th. There was a light dusting on the ground by mid morning from Troup to Carroll county, east to Fayette county. Due to the dry layer of air aloft, much of the precipitation evaporated before reaching the ground, so eastward progression of the area of snow was slow. By evening, a mixture of light snow, sleet and freezing rain became more widespread over west central and northwest Georgia. Although the…
