DROUGHT INFORMATION STATEMENT FOR NORTH AND CENTRAL GEORGIA
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
1110 AM EDT THU SEP 1 2016

...TROPICAL STORM HERMINE WILL LIKELY IMPROVE THE DROUGHT CONDITIONS
OVER CENTRAL GEORGIA...
...A SHORT-TERM...SEVERE TO EXTREME DROUGHT CONTINUES OVER PORTIONS
OF NORTH GEORGIA INCLUDING THE ATLANTA METRO AREA...

A FEW DAYS OF SCATTERED SHOWERS AND THUNDERSTORMS BROUGHT SOME
MINOR RELIEF TO THE SHORT-TERM DROUGHT CONDITIONS ACROSS NORTH
AND CENTRAL GEORGIA DURING THE PAST 14 DAYS. SCATTERED RAINFALL
AMOUNTS OF 0.5 TO 1.5 INCHES PREVAILED WITH SOME ISOLATED SPOTS
RECEIVING 2 INCHES. HOWEVER...AROUND 60 PERCENT OF THE AREA
RECEIVED LESS THAN A HALF INCH.  THIS HAS ALLOWED RAINFALL
DEFICITS TO GRADUALLY WORSEN IN MANY LOCATIONS DURING THE PAST
SIX MONTHS.

DUE TO CONSISTENT VERY WARM TEMPERATURES IN THE 80S AND 90S WITH
HIGH EVAPORATION RATES...THE SOIL MOISTURE CONTINUES TO DECLINE IN
AREAS THAT RECEIVED LESS THAN 2 INCHES OF RAIN ACROSS NORTH AND
CENTRAL GEORGIA DURING THE PAST TWO WEEKS. CONSEQUENTLY...A SEVERE
TO EXTREME DROUGHT PREVAILS OVER NORTH GEORGIA WHICH INCLUDES THE
ATLANTA METRO AREA. THE DRIEST AREAS WERE FROM SUMMERVILLE TO DALTON
...CANTON TO MARIETTA AND LAGRANGE THROUGH BARNESVILLE TO MCDONOUGH.
ABNORMALLY DRY TO SEVERE DROUGHT CONDITIONS PERSIST OVER PORTIONS
OF CENTRAL GEORGIA.

SOME MINOR HYDROLOGICAL IMPACTS TO WATER SUPPLY...STREAM FLOWS AND
GROUND WATER TABLES ARE CONTINUING TO OCCUR OVER MOST OF NORTH GEORGIA.
THIS INCLUDES THE LAKE LANIER POOL ELEVATION WHICH HAS FALLEN ANOTHER
HALF FOOT DURING THE PAST TWO WEEKS.

U.S. DROUGHT MONITOR IMAGE AND OTHER DROUGHT RELATED INFORMATION.
