CLASSIFICATION OVER NORTHEAST SOUTH CAROLINA AND SOUTHEAST NORTH
CAROLINA. THE CLASSIFICATION IS ABNORMALLY DRY...OR RECOVERING
DROUGHT...FOR THE ENTIRE HYDROLOGIC SERVICE AREA...EXCEPT FOR A
SMALL PORTION OF MARLBORO COUNTY STILL IN MODERATE DROUGHT.
AREA STREAMFLOWS HAVE FALLEN IN RECENT WEEKS TO NORMAL TO SLIGHTLY
BELOW NORMAL LEVELS. HOWEVER...UPSTREAM RESERVOIRS REMAIN AT
LEVELS WHICH ARE NEAR OR SLIGHTLY ABOVE NORMAL. SOIL MOISTURE
CONDITIONS ARE NOW NEAR TO SLIGHTLY BELOW NORMAL.
OVER THE NEXT WEEK...A COLD FRONT WILL BRING SCATTERED SHOWERS
AND THUNDERSTORMS TO THE AREA SUNDAY THROUGH TUESDAY.

14 DAY OUTLOOK CALLS FOR BELOW NORMAL PRECIPITATION WHILE THE

EQUAL CHANCES OF NORMAL...BELOW NORMAL AND ABOVE NORMAL
