Coweta County

Every recorded tornado

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

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).

   National Weather Service narrative

   A National Weather Service survey determined that an EF4 tornado with maximum wind speeds 170 MPH and a maximum path width of 1850 yards occurred in Coweta County. The Heard County tornado crossed into Coweta County along Bob Wilson Road and gained strength as it moved east-northeast crossing JD Walton Road and travelled up Smokey Road with trees falling on some homes. Wind speeds quickly increased to over 150 MPH, EF3 intensity, near Timberland Trail on the southwest side of Newnan. Many homes had major damage and one home had all but the back wall collapse. The family survived with no injuries by taking shelter in their bathtub. The tornado continued east-northeast crossing…

2. Mar 26, 2011Hail$6.5 million
   National Weather Service narrative

   Literally dozens of reports of large damaging hail were received from the public across southern Coweta county from Grantville, Moreland, eastward to Senoia. Most of the hail was the size of golf balls, but hail the size of baseballs, tennis balls, and even isolated reports of grapefruit-sized hail were received from the Grantville area eastward to just south of Moreland. Hail decreased in size to half-dollars by the time it reached areas just south of Senoia. Significant accumulations of hail were noted on the ground in the area and much of the region was blanketed with a hail cover for an hour or more. Extensive damage was observed to vehicles and roofs of homes in the area.

3. Feb 18, 2009Hail$4.0 million
   National Weather Service narrative

   Very large hail was observed in far northeast Coweta county. Numerous reports of large hail were also received from northeast Coweta county. The hail fell from a supercell that tracked across the northeast part of the county from just south of Palmetto, along the Fulton-Coweta county line to just east of Cannongate along the Fayette county line. The large hail storm continued into northern Fayette county as well. The Coweta County Emergency Management County Director reported 4.25 inch diameter hail approximately four miles northeast of Madras near the Fulton county line. Several reports of golf ball-sized hail were received from the public in the Cannongate area. Extensive damage…

8. Jan 22, 2000Ice Storm, Coweta$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…

9. Feb 18, 2009Hail$700,000
   National Weather Service narrative

   The public observed golf ball-sized hail in the Newnan area and nickel-sized hail south of Sharpsburg. Nickel-sized hail was observed around Turin.

    National Weather Service narrative

    The public observed golf ball-sized hail in northern Coweta county, just southwest of Roscoe and half-dollar-sized hail about five miles north of Newnan. A storm spotter observed nickel-sized hail in the Sargent area.
