Richmond and Columbia counties remain in extreme drought, the second-worst category, and the line of counties reclassified as exceptional is creeping closer.
"All counties in Georgia south of Harris, Talbot, Upson, Pike, Lamar, Monroe, Jasper, Putnam, Hancock, Warren, McDuffie and Lincoln counties, inclusive, are either in extreme or exceptional drought," Stooksbury wrote.
