Drought conditions continue to worsen across the entire state. Of Georgia's 159 counties, 74 are classified as being in extreme drought, 79 in severe drought and six in moderate drought.
The drought has become extreme across the north Georgia counties of Bartow, Carroll, Cherokee, Clayton, Cobb, Coweta, DeKalb, Douglas, Fannin, Fayette, Fulton, Gilmer, Gordon, Haralson, Harris, Heard, Meriwether, Murray, Paulding, Pickens, Towns, Troup, Union and Whitfield.
In northwest Georgia, Catoosa, Chattooga, Dade, Floyd, Polk and Walker counties remain in extreme drought.
Across south Georgia, 44 counties are classified as being in extreme drought.
Since early May, extreme drought conditions expanded into the south Georgia counties of Ben Hill, Bulloch, Candler, Colquitt, Decatur, Effingham, Evans, Irwin, Mitchell, Montgomery, Seminole, Tattnall, Telfair, Tift, Toombs, Turner, Wheeler and Worth.
Extreme drought conditions remain in the south Georgia counties of Appling, Atkinson, Bacon, Berrien, Brantley, Brooks, Bryan, Camden, Charlton, Chatham, Clinch, Coffee, Cook, Echols, Glynn, Grady, Jeff Davis, Lanier, Liberty, Long, Lowndes, McIntosh, Pierce, Thomas, Ware and Wayne.
Moderate drought exists in the east Georgia counties of Burke, Columbia, Elbert, Hart, Lincoln and Richmond. Conditions in counties now classified as being in moderate drought are deteriorating very quickly.
The remaining 79 counties in Georgia are classified as being in severe drought.
Extreme drought conditions are defined as those expected once in 50 years, based on many indicators. Severe drought conditions are those we expect once in 20 years.
Preliminary rainfall deficits for Jan. 1 through May 21 include Athens at 6.49 inches, Augusta 6.61, Savannah 7.63, Columbus 8.68, Brunswick 9.28, Macon 9.30, Atlanta 10.02, Plains 10.09, Alma 11.15, Tiger 11.45, Tifton 11.72, Blairsville 13.89 and LaFayette 14.05.
The U.S. Geological Survey reports daily record to near-record low stream flows for May 21 across all of Georgia.
Across north Georgia, record low flows for May 21 are reported on the Chattooga River near Clayton, the Coosawattee near Ellijay and Pine Chapel, the Conasauga at Tilton, the Oostanaula at Resaca and near Rome, the Middle Oconee near Athens, the Oconee at Milledgeville and the Ocmulgee near Jackson.
Across south Georgia, record low flows are reported on the Ocmulgee River at Lumber City, the Oconee at Dublin, the Flint at Newton and Bainbridge, the Ochlockonee near Thomasville, the Alapaha near Alapaha, the Satilla near Waycross and at Atkinson and the Suwannee at Fargo.
Groundwater levels are dropping statewide. Many wells are approaching their average yearly low water level, which is reached normally in late summer or early fall.
Little if any widespread, sustained relief from the drought is anticipated. The long-term outlook is for the drought to continue to intensify.
If extremely dry conditions continue into the summer, afternoon temperatures between 100 and 105 will be common across the Coastal Plain and Piedmont regions of the state. Temperatures in the 90s will be common across the mountains.
The entire state remains under the level-2 outdoor water-use schedule. Outdoor watering is allowed from midnight to 10 a.m. on Sundays, Tuesdays and Thursdays at odd-number street addresses and on Mondays, Wednesdays and Saturdays at even-number addresses. It's banned all day on Fridays.
Local water authorities may further restrict outdoor watering.
