Drought Information Statement for North and Central Georgia
National Weather Service Peachtree City GA
1135 AM EDT Thu May 11 2017

...LONG-TERM SEVERE TO EXTREME DROUGHT CONTINUES ACROSS NORTH
GEORGIA WITH SLIGHT IMPROVEMENT...
...SHORT-TERM MODERATE DROUGHT CONTINUES ACROSS CENTRAL GEORGIA...

SYNOPSIS...

North and central Georgia has been in a relatively active period
over the last two weeks, with rain occurring every two to four days.
The most significant rainfall amounts occurred April 27-28, April 30-
May 1, and May 4-5. Observed rainfall amounts have been high enough
to continue to promote drought improvement across northwest Georgia,
and portions of west central Georgia.

SUMMARY OF IMPACTS...

SOIL MOISTURE CONDITIONS.
Due to recent rainfall, conditions in the shallow soil profile are
Abnormally Moist to Wet across north Georgia, and neutral elsewhere.
The deeper soil profile still highlights the long term moderate to
severe drought conditions over portions of north Georgia, and the
developing moderate drought conditions over central Georgia.

Overall, the long-term drought persists with enough improvement that
the Extreme and Severe Drought areas now only include portions of
five counties: Pickens, Dawson, Lumpkin, Hall, and White. Only
Lumpkin and White are included in the Extreme Drought area.

The Chattahoochee Basin, extending from the Extreme/Severe Drought
area, through metro Atlanta, and into the Tallapoosa Basin along the
GA/AL border remains in a Moderate Drought.

The short-term drought persists across middle Georgia, though aside
from a one category improvement in portions of west central Georgia,
no changes have been made in the last two weeks. Severe and Extreme
Drought in far southern Georgia have expanded, and without
significant rainfall amounts, portions of central Georgia may begin
to see a degradation of conditions into the Severe Drought category
over the next few weeks.

RIVER AND STREAM FLOW CONDITIONS.
Some hydrological impacts to the water supply are still occurring,
though there has been significant improvement from earlier in the
year. Average stream flows and ground water tables for the last 14-
days are still below normal, particularly across the upper
Chattahoochee River Basins and across central Georgia. Normal to
above normal stream flow conditions were occurring across far north
Georgia. Please note that creeks and smaller rivers can change
quickly due to runoff from heavy rain if it occurs.


FIRE DANGER HAZARDS.
The latest fire danger assessment indicates a moderate to high risk
across the majority of north and central Georgia, north of a line
from Columbus, to Macon, to Washington. There is a very high to
extreme risk south of this line, extending into south Georgia.
Please note that this assessment can change rapidly due to changes
in moisture levels and rainfall received.

CLIMATE SUMMARY...

Over the last two weeks, 0.5 to 6.0 inches of rainfall occurred over
north and central Georgia. In general, the highest rainfall amounts
occurred in far west central Georgia, extending on either side of a
line from Columbus, to Talbotton, to Roberta. In this area, 2 to 6
inches of rain was observed, or 150 to 400 percent of normal.
Rainfall amounts of 2 to 5 inches (or 110 to 300 percent of normal)
also occurred in north Georgia, north of a line from Summerville, to
Dawsonville, to Elberton.

Outside of these two regions, rainfall amounts varied from 0.50 to
2.0 inches, with the lowest amounts occurring in the greater Athens
and far east central Georgia areas. These amounts were 25 to 90
percent of normal.

Given that the state is being impacted by both long term and short
term drought conditions, two tables have been provided below. The
first table indicates the the total rainfall and departures for the
last 365 days (long term drought), while the second is for the last
90 days (short term drought).

HYDROLOGIC SUMMARY AND OUTLOOK...

Current lake levels at USACE Projects were mainly below summer pool
levels, ranging from around 2 feet below summer pool at West Point
to around 8 feet below at Thurmond and Lanier. The exceptions were
Carters Lake and Allatoona, which were 1.5 feet above summer pool
and at summer pool, respectively.

The pool levels are projected to remain near steady or slightly
decrease for the next four weeks.

Summer pool level are considered the target elevation through the
summer and into the fall months, and the elevation departure will be
relative to the summer pool level until further notice.
