...SEVERE DROUGHT EXPANDS ACROSS SOUTHEAST SOUTH CAROLINA AND
SOUTHEAST GEORGIA...

SYNOPSIS...
Below normal rainfall has continued since the start of the year
and drought conditions have steadily worsened and expanded across
southeast South Carolina and southeast Georgia. Severe Drought
(D2) now covers nearly the entire area. Moderate Drought (D1)
persists in Jenkins and Candler counties and inland portions of
Tattnall, Evans, Bulloch, and Screven counties in southeast
Georgia as well as far inland areas of Allendale and Berkeley
counties in southeast South Carolina.

CLIMATE SUMMARY...
Since the start of 2018, rainfall amounts are 4 to 6 inches below
normal across nearly all of southeast South Carolina and
southeast Georgia. Furthermore, there are some pockets along the
coast that are as much as 6 to 8 inches below normal. At the
Savannah/Hilton Head International Airport (KSAV), rainfall is
7.01 inches below normal for the year through 4/19. This is just
43 percent of normal and ranks as the 8th driest on record through
this point in the year. At the Charleston International Airport
(KCHS), rainfall is 4.35 inches below normal for the year through
4/19. This is 64 percent of normal and ranks as the 13th driest on
record through this point in the year. Also, for the last 60, 90,
and 180 days, rainfall for much of the area is running roughly 25
to 75 percent of normal.

PRECIPITATION/TEMPERATURE OUTLOOK...
Over the next 7 days, the current forecast indicates a good chance
for a widespread significant rainfall event across all of southeast
South Carolina and southeast Georgia late this weekend and early
next week. The current forecast shows the potential for rainfall
amounts around 2 inches, with locally higher amounts possible.
The precipitation outlook for the 8 to 14 day time period
indicates an increased chance for below normal rainfall. However,
the 1-month time period (valid for May) indicates an increased
chance for above normal rainfall. The 3-month outlook (valid for
May through July) reflects equal chances for above normal, near
normal, or below normal rainfall.

HYDROLOGIC SUMMARY AND OUTLOOK...
As of April 20th, the 14 day average streamflow across southeast
South Carolina and southeast Georgia was below normal with much of
the area supportive of moderate hydrologic drought. Soil moisture
ranges between 10 and 20 percent of normal across the entire
region, with portions of southeast Georgia ranging as low as 5 to
10 percent of normal. Finally, the seasonal drought outlook
produced by the Climate Prediction Center forecasts that drought
conditions will likely improve but persist into the beginning of
summer.

NEXT ISSUANCE DATE...
This product will be updated by May 4th, 2018 or sooner if
necessary in response to significant changes in conditions.
