March rain relieves Georgia drought
An unusually wet March has brought major drought relief to north
Georgia. Only the Lake Lanier and Lake Hartwell basins are now in
drought. The remainder of north Georgia is drought-free.
Abnormally dry to moderate drought conditions continue across south
Georgia, however.
Though relief has come, long-term rainfall deficits are still a
concern. Small and medium reservoirs are full. The major exceptions
are Lake Lanier and the Savannah River Valley reservoirs Hartwell,
Russell and Clarks Hill.
Rain across the piedmont and mountains have resulted in the soil
moisture being near normal for the end of March. However, soils across
south Georgia remain abnormally dry.
The counties in north Georgia classified as being in moderate drought
are Union, Towns, Rabun, Lumpkin, White, Habersham, Hall and Stephens.
With the exception of northwest Georgia, which has normal moisture
conditions for late March, the rest of north Geogia is classified as
abnormally dry because of long-term rain deficits.
Coastal plain counties in south Georgia are classified as being
abnormally dry or in moderate drought. Abnormally dry counties are
south and west of Muscogee, Chattahoochee, Marion, Schley, Sumter,
Lee, Worth, Colquitt and Brooks. The remaining coastal plain counties
are classified as being in moderate drought.
Currently the climate pattern is a weak La Niña pattern tending toward
a neutral pattern. A typical weak La Niña spring brings wet weather
across the northern piedmont into the mountains, just like north
Georgia experienced in March.
However, across the coastal plain and southern piedmont, a weak La
Niña spring is usually warm and dry. Outside the series of storms that
crossed the coastal plain over the last several days, the expected La
Niña pattern has occurred.
