Update on flooding

From the National Weather Service in Wilmington:

AS OF 400 AM SATURDAY...MOSAIC RADAR AND SATELLITE DATA ARE  TRENDING GRADUALLY TOWARD THE FORECAST EXPECTATION OF A SPATIAL  SHIFT IN THE HEAVY RAIN AXIS ALONG A CHARLESTON TO COLUMBIA TO  GREENVILLE SC TRACK. A FLOOD WATCH HOWEVER WILL REMAIN INTACT  ACROSS SE NC AND NE SC AS GROUNDS ARE EXCEEDINGLY SOGGY AND ANY  ADDITIONAL RAINFALL WILL RAPIDLY LEAD TO DRAINAGE WOES. APPEARS  SE NC WILL EXPERIENCE A LULL THIS MORNING AS PROBLEMATIC RAINS  SHIFT TOWARD CENTRAL AND WESTERN SC. THE ALLEVIATION OF RAINFALL  HOWEVER LOOKS TO BE BRIEF AS ADDITIONAL TORRENTS OFF THE OCEAN  MIGRATE LANDWARD THIS AFTERNOON ACROSS THE REGION. SIGNALS IN  SEVERAL OF THE MODELS SUGGEST ANOTHER BREAK IN +SHRA MAY UNFOLD  TONIGHT...FOLLOWED BY AN ONSLAUGHT OF DOWNPOURS INTO EARLY SUNDAY  MORNING.

and from The National Weather Service in Raleigh:

...ANY MAINSTEM RIVER FLOODING THIS WEEKEND WILL BE MINOR...    RIVER FLOOD WARNINGS REMAIN IN EFFECT THIS WEEKEND FOR THE HAW AND  UPPER NEUSE RIVER BASINS FOR MINOR FLOODING WHICH REACHES OR EXCEEDS  THE FLOOD STAGE BY A FEW FEET AT MOST. SEE WATER.WEATHER.GOV FOR  DETAILS AT INDIVIDUAL RIVER FORECAST POINTS.    THE AXIS OF HEAVIER RAIN OVER EASTERN NC THIS AFTERNOON IS EXPECTED  TO PIVOT WEST...WITH MUCH LESS ADDITIONAL RAINFALL ON SATURDAY.  EXPECTED ADDITIONAL RAINFALL THROUGH SATURDAY EVENING IS EXPECTED TO  RANGE FROM <2 INCHES IN THE EAST TO 3-4 INCHES IN THE WEST. THIS  REDUCTION IN THE AMOUNT OF RAIN EXPECTED LATER IN THE EVENT WILL  GREATLY REDUCE THE CHANCE OF SIGNIFICANT MAINSTEM RIVER FLOODING...  AS WHILE THE TOPSOIL (SEE 0-10CM & 0-200CM RELATIVE SOIL MOISTURE  FROM NASA HTTP://WEATHER.MSFC.NASA.GOV/SPORT) IS APPROACHING  SATURATION...THE DEEPER SOIL COLUMN HAS NOT RECOVERED...CONTAINING  <50% OF THE MOISTURE REQUIRED FOR SATURATION. AS SUCH...THERE IS  STILL PLENTY OF STORAGE AVAILABLE IN THE DEEPER SOILS WHICH WILL  REDUCE RUNOFF...ESPECIALLY IF THE RAINFALL RATE IS NOT HIGH.    THERE WILL STILL BE A THREAT OF FLASH FLOODING...FOR AS NOTED  ABOVE...THE UPPER SOIL IS NEAR SATURATION SO HEAVIER RAINFALL WOULD  PRODUCE VERY SWIFT RUNOFF INTO SMALL STREAMS OR LOW-LYING  AREAS...AND PARTICULARLY IN URBAN AREAS.    IN THE MEDIUM RANGE...THERE IS A CHANCE THAT THE HEAVY RAIN THREAT  COULD ROTATE AROUND THE UPPER TROF AND BACK ACROSS THE AREA ON  SUNDAY AND MONDAY. THERE IS NOT HIGH CONFIDENCE IN POTENTIAL AMOUNTS  AT THIS TIME...AND WE WILL NEED TO ASSESS OUR HYDROLOGIC STATUS  AFTER THIS FIRST ROUND OF RAINFALL...STAY TUNED.
