After five months of above-normal temperatures and dry conditions, almost 75 percent of Georgia is now experiencing some level of drought.
Because of the continued hot, dry conditions, the drought expanded and strengthened west of a line running from Screven County, Georgia, in the north to Ware County, Georgia in the south. The U.S. Department of Agriculture’s Drought Monitor shows that areas affected by extreme drought – the fourth drought level on the monitor’s five-level scale – grew from 11 percent to 40 percent of the state. Areas affected by exceptional drought – the most severe drought designation – expanded to cover 14 percent of the state.
Hurricane Matthew, which struck the Georgia coast the weekend of Oct. 8, brought rainfall to coastal Georgia, but the rest of the state saw extremely warm and dry conditions, with only one or two days of measurable rain.
Lake Lanier, north of Atlanta, reached its lowest point in the last four years last month. Twenty-two public boat ramps were closed due to low water. In Haralson County, Georgia, west of Atlanta, the Tallapoosa River dropped below the intake level for the water plant there. Water was imported for schools and residents took drastic water conservation measures.
Numerous forest fires occurred across the driest areas of the state, and residents were encouraged not to start fires, especially at the end of the month. Some of the fires were spread by strong winds around Hurricane Matthew.
Winds from Hurricane Matthew also blew many green pecans off the trees in the southeast corner of the state. In Tattnall County, Georgia, about one-third of the pecan trees were toppled by the winds and will take years to replace. Cotton was blown off of plants to the ground and yield will be significantly reduced. In addition to agricultural damage, three people were killed in Georgia due to the hurricane, millions lost power and many people evacuated inland ahead of the storm.
Despite the hurricane-fueled rain in part of the state, rain reports from many National Weather Service reporting stations tied records for being the driest October on record. Athens, Georgia, saw the second-driest October in 114 years of record following 1963, which had no rain. Savannah, Georgia, saw the third-wettest October in 143 years, after 19.84 inches in 1994 and 12.50 inches in 1990.
Daily rainfall records were set in Alma, Georgia on Oct. 7 with 2.83 inches, surpassing the old record of 1.84 inches set in 1996, and in Savannah on Oct. 8 with 2.57 inches, breaking the old record of 2.10 inches set in 1952.
According to National Weather Service reporting stations, the highest monthly total precipitation was 11.60 inches in Savannah, 7.91 inches above normal. The lowest monthly total precipitation was recorded in Albany, Georgia, with just a trace of rain, 2.59 inches below normal.

Community Collaborative Rain, Hail and Snow Network volunteers along the coast reported daily rainfall amounts of 10 inches or more on the morning of Oct. 8 after the passage of Hurricane Matthew. A Garden City, Georgia, observer in Chatham County reported 13.86 inches that morning, after taking three separate readings of the gauge to keep it from overflowing. The highest monthly rainfall of 14.58 inches was measured south of Savannah in Chatham County, followed by 14.12 inches reported by the Garden City observer.
