NWS SOUTHEAST RIVER FORECAST CENTER ATLANTA, GA
1220 PM EST WED FEB 3 2016

...THE SPRING FLOOD OUTLOOK CALLS FOR ABOVE NORMAL POTENTIAL OF
RIVER FLOODING ACROSS SOUTH CAROLINA...NORTH CAROLINA...AND SOUTHERN
VIRGINIA THROUGH APRIL...

HISTORICALLY FOR THE CAROLINAS AND SOUTHERN VIRGINIA...THE RIVER
FLOOD SEASON BEGINS IN EARLY TO MID JANUARY...WITH THE NUMBER OF
RIVER FLOOD EVENTS INCREASING THROUGH LATE WINTER WITH A PEAK IN
EARLY TO MID MARCH...ENDING IN LATE APRIL FOR THE REGION.
HOWEVER...THIS FLOOD SEASON HAS BEGUN EARLY AND HAS SET THE STAGE
FOR MORE FLOODING IN THE COMING MONTHS.

FOR THIS REGION...STREAMFLOWS ARE RUNNING ABOVE NORMAL...MEDIUM AND
LONG RANGE PRECIPITATION GUIDANCE LEANS TOWARDS WET WEATHER THROUGH
APRIL. THE POTENTIAL FOR EXCESSIVE RUNOFF AND RIVER FLOODING WILL
CONTINUE THIS WINTER DUE TO WET SOILS...FORECASTED ABOVE NORMAL
RAINFALL AND LAKES THAT ARE FULL. OVERALL...THE RELATIVE RISK IS
WELL ABOVE NORMAL.

CURRENT STREAMFLOWS...THE 14-DAY AVERAGE STREAMFLOWS PROVIDED BY THE
USGS AS OF FEBRUARY 2ND ARE RUNNING MUCH ABOVE NORMAL THROUGHOUT THE
CAROLINAS AND VIRGINIA.

PAST PRECIPITATION...PRECIPITATION OVER THE LAST 30 DAYS...BASED ON
SERFC MULTISENSOR PRECIPITATION ESTIMATES...HAS BEEN NEAR TO ABOVE
NORMAL ACROSS MOST OF THE AREA.

RESERVOIRS...MOST RESERVOIRS ARE ABOVE THEIR TARGET POOLS FOR THIS
TIME OF YEAR.

SNOW PACK...NO HYDROLOGIC SIGNIFICANT SNOW PACK AT THIS TIME.

FUTURE PRECIPITATION...THE LATEST MEDIUM RANGE METEOROLOGICAL MODELS
INDICATE A SLIGHTLY DRIER AND COOLER WEATHER PATTERN OVER THE NEXT
TWO WEEKS. THE LATEST CPC 8 TO 14 DAY OUTLOOK IS INDICATING A COOLER
AND DRIER PATTERN AS WELL.

AS FAR AS LONGER TERM PRECIPITATION OUTLOOKS...BASED ON THE CPC LONG
LEAD OUTLOOK...ABOVE NORMAL PRECIPITATION IS EXPECTED THROUGHOUT THE
REGION WITH THE BEST CHANCES FOR ABOVE NORMAL AS YOU APPROACH THE
COASTAL AREA. THIS IS BASED ON CPC CLIMATE MODEL FORECASTS AND THE
CURRENT EL NINO ADVISORY.
