Hall County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Hall County: 10.
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.

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. Mar 20, 1998Tornado$15.0 million
   National Weather Service narrative

   The tornado began in northwest Hall county and moved into southern White county. Total distance covered was about 13 miles. Aerial and ground surveys by NWS employees showed extensive damage along the path. There was significant damage to Lanier Elementary School and North Hall High School. Houses, trailers, businesses, and agricultural interests (namely the poultry industry) were demolished or damaged. Large areas of forest were flattened. A tractor-trailer truck was thrown 100 feet from the road into a school, killing the driver. All of the other 11 persons killed were in mobile homes. The damage path varied from 50 to 200 yards, but averaged around 100 yards wide.

2. Apr 6, 2016Thunderstorm Wind$3.0 million
   National Weather Service narrative

   A National Weather Service survey team found a 4.6 mile long, 0.5 mile wide, path of thunderstorm wind damage stretching from around the Old Federal Road Park on the shores of Lake Lanier northeast to the area around Mundy Mill Road and Millside Parkway northeast of Oakwood. Hundreds of trees were blown down causing damage to over 53 homes. Five homes were destroyed and nine had major damage. No injuries were reported.

3. Apr 24, 2021Hail$1.8 million
   National Weather Service narrative

   A retired National Weather Service employee reported hail as big as golf balls on Chestatee Point on Lake Lanier.

4. Mar 21, 2017Hail$1.8 million
   National Weather Service narrative

   An amateur radio operator reported golf ball size hail.

5. Mar 26, 2011Hail$1.8 million
   National Weather Service narrative

   The public observed golf ball-sized hail in Flowery Branch. Otherwise, mostly quarter-sized hail was observed elsewhere across the southern part of Hall county near Oakwood and Flowery Branch. WSR-88D radar data suggests that quarter-sized hail likely continued eastward toward Chestnut Mountain.

6. Mar 15, 2008Hail$1.0 million
   National Weather Service narrative

   Numerous reports of large hail, the size of quarters and larger, were received from the public and the broadcast media across the northern half of Hall county. Nickel-sized hail was reported by the public in Murrayville in northwest Hall county, ping-pong ball-sized hail west of Gainesville on the east side of Lake Lanier, with at least a half-a-dozen reports of ping-pong to golf ball-sized hail around the Gainesville area. The Times of Gainesville reported that Hardy Chevrolet had up to 500 vehicles suffering some form of damage from hail. At Moss Robertson Cadillac/Mazda/Isuzu, more than 100 vehicles were damaged from hail. Milton Martin Honda had 63 vehicles damaged from hail.

7. Apr 4, 2007Thunderstorm Wind$1.0 million
   National Weather Service narrative

   A survey conducted by the National Weather Service in Peachtree City, Georgia and damage reports received from the Hall Emergency Management Director, a cooperative observer, and the public confirmed that a microburst with straight-line winds of 70 to 80 mph with isolated damage of 100-110 mph caused considerable damage to a subdivision just east of Interstate-985 and just south of Flowery Branch. The path of damage was approximately one-half mile long and a mile wide. At least 35 homes sustained roof and siding damage and dozens of large trees were blown down or completely uprooted in the area. One home was blown 15 feet off its foundation and destroyed as it collapsed. Windows…

8. Jun 22, 2008Hail$1.0 million
   National Weather Service narrative

   Several reports of large hail were received from the public from the area between Murrayville and Gainesville. Golf ball-sized hail was observed two miles north of Gainesville, while quarter-sized hail was observed four to five miles northwest of Gainesville, or just southeast of Murrayville. Hail covered the ground in these later areas. A few trees were also blown down in the area.

9. May 19, 2013Flash Flood$1.0 million
   National Weather Service narrative

   Trudy Drive was completely washed out by a drainage branch flowing into Lake Lanier. There was a 50 to 75 foot large gap in the road with at least a 10 foot drop off. Several other roads were closed and damaged by flood waters as drainage branches become rapidly flowing creeks and overwhelmed culverts. These roads included portions of Atlanta Highway, McEver Road, Stephens Road, Flowery Way, Spring Street and Cove Creek Road in the Flowery Branch area.

10. Apr 10, 2009Hail$1.0 million
    National Weather Service narrative

    The public observed nickel to quarter-sized hail near the Gwinnett county line south of Flowery Branch and golf ball-sized hail in the Gainesville area. Radar data suggests that large hail, likely near golf ball-sized hail continued northeast from Gainesville toward Lula.

1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
