- Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
- 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.

National Weather Service narrative
A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that the fifth tornado of the major tornado outbreak of April 27th and 28th once again entered Georgia from Alabama and affected Polk, Floyd, and Bartow counties in Georgia. This tornado was an EF2 and entered Polk county from Cherokee county Alabama. It was a long-lived well tracked supercell and was likely the same supercell which spawned the EF5 tornado that destroyed Tuscaloosa, Alabama. The tornado only tracked across a small portion of extreme northwest Polk county before moving into south west Floyd county, just south of Cave Spring. The total tornado path length…

- Jan 22, 2000Ice Storm, Polk$980,000
National Weather Service narrative
Wintry precipitation plagued the northern third of Georgia beginning Saturday and continued into Sunday. A shallow cold airmass with single-digit dewpoint temperatures was in place over north Georgia, with temperatures in the upper 20s to lower 30s over much of the area. An upper level disturbance moved rapidly over the area in a fast zonal flow, bringing an increase in mid-tropospheric moisture. At the same time, lower level moisture spread into the area from the Gulf of Mexico. Precipitation began falling into the colder layer of air near the surface by mid-morning on the 22nd. The mixture of light rain, snow and sleet had spread from northwest to northeast Georgia by early…
