A perigean spring tide created favorable conditions for salt water flooding along portions of the South Carolina coastline.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1026 PM EDT TUE JUN 5 2012
.SYNOPSIS...
A STATIONARY FRONT WILL STALL AND LINGER OVER OR NEAR THE REGION
INTO THURSDAY NIGHT. HIGH PRESSURE WILL BUILD INTO THE SOUTHEAST
STATES INTO EARLY NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A NEARLY STATIONARY FRONT SOUTH OF I-16 WILL BUCKLE BACK TO THE
NORTH LATE TONIGHT AS A WAVE OF LOW PRESSURE IN SE ALABAMA MOVES
INTO SOUTHERN GA AFTER 08Z. THE PROXIMITY OF THE FRONT AND SURFACE
LOW ALONG WITH AN INCREASE IN ISENTROPIC LIFT ON THE 300-305K
SURFACES WILL LEAD TO AN INCREASE IN SHOWERS THROUGH THE NIGHT.
ADDITIONAL FORCING FOR ASCENT WILL RESULT FROM A 25-30 KT LOW
LEVEL JET THAT MOVES INTO SE GA LATE TONIGHT...ALONG WITH LOW
LEVEL CONVERGENCE OFF THE ATLANTIC WITHIN AN ONSHORE FLOW MUCH OF
THE NIGHT. SURFACE BASED INSTABILITY WILL BE LIMITED...BUT THERE
DOES LOOK TO BE ENOUGH ELEVATED INSTABILITY TO PRODUCE AT LEAST
ISOLATED T-STORMS OVER OVER SOUTHERN AND CENTRAL ZONES AFTER
MIDNIGHT. RAIN PROBABILITIES WILL RANGE FROM 40-60
PERCENT...HIGHEST OVER SOUTH AND SE ZONES...LOWEST ACROSS OUR NW
SECTIONS. TEMPS WILL CHANGE LITTLE THROUGH THE NIGHT...GENERALLY
HOLDING IN THE MID AND UPPER 60S...EXCEPT FOR SOME LOWER 60S ALONG
THE NW TIER.
STRATUS WILL DEVELOP LATE TONIGHT AND DROP DOWN WITH THE FORMATION
OF THE INVERSION. THAT ALONG WITH EARLIER RAINS WILL CREATE A
SMALL REDUCTION IN SURFACE VISIBILITIES.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
THE STALLED COLD FRONT WILL LINGER OVER OR CLOSE TO OUR SOUTHERN
COUNTIES WEDNESDAY INTO WEDNESDAY NIGHT BEFORE PUSHING SOUTH OF THE
AREA BY THURSDAY. THE BEST MOISTURE...LIFT AND INSTABILITY WILL BE
LOCATED ALONG AND SOUTH OF THE FRONT AND THEREFORE WILL MAINTAIN THE
HIGHEST THREAT FOR RAIN IN THE FORM OF THUNDERSTORMS IN THE FAR
SOUTH WEDNESDAY AND WEDNESDAY NIGHT...TAPERING TO MUCH LOWER CHANCES
IN THE NORTHWEST. ABUNDANT CLOUD COVER ON WEDNESDAY WILL ONCE AGAIN
KEEP HIGH TEMPERATURES A GOOD 5 TO 8 DEGREES BELOW NORMAL.
WITH SURFACE HIGH PRESSURE BUILDING INTO THE AREA ON THURSDAY AND
THE DEEPER MOISTURE BEING SHUNTED OFF TO THE EAST...THE THREAT FOR
RAIN WILL CERTAINLY BE DIMINISHED AND WILL CARRY MAINLY SLIGHT
CHANCE POPS FOR THURSDAY IN MOST AREAS. MORE SUNSHINE WILL HELP
AFTERNOON HIGHS IN THURSDAY TO REBOUND INTO THE MID TO UPPER 80S IN
MOST LOCALS AWAY FROM THE COAST.
CONTINUED DRYING OF THE ATMOSPHERE IN COMBINATION WITH UPPER LEVEL
RIDGING BUILDING INTO THE AREA ON FRIDAY SHOULD LIMIT ANY
PRECIPITATION FROM OCCURRING...EXCEPT FOR PERHAPS A FEW ISOLATED
SHOWERS ALONG THE SEA BREEZE. THE THREAT FOR PRECIPITATION IS LOW
ENOUGH ON FRIDAY TO NOT INCLUDE MENTION IN THE FORECAST. HIGHS ONCE
AGAIN IN THE MID TO UPPER 80S AWAY FROM THE COAST.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
DEEP HIGH PRESSURE WILL MOVE IN THROUGH THE WEEKEND KEEPING RAIN
CHANCES VERY LOW. COULD SEE A SLIGHT INCREASE IN RAIN CHANCES EARLY
NEXT WEEK DEPENDING ON HOW QUICKLY THE UPPER RIDGE BREAKS
DOWN...WITH THE 00Z/05 ECMWF MORE AGGRESSIVE IN DOING SO COMPARED TO
THE 00Z/05 GFS. TEMPERATURES WILL BE NEAR NORMAL.
&&
.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
KCHS...VFR CONDITIONS WILL PREVAIL MUCH OF TONIGHT...UNTIL THE
STATIONARY FRONT TO THE SOUTH BUCKLES A LITTLE NORTH LATE TONIGHT
AND WEDNESDAY MORNING. THE CLOSE PROXIMITY OF A WAVE OF LOW
PRESSURE WHICH WILL RIDE ALONG THE FRONT TO THE SOUTH OF THE
TERMINAL...IT LOOKS TO GENERATE MVFR OR LOWER CONDITIONS FROM
08-17Z. WHILE WE CANNOT RULE OUT ISOLATED TSRA...WITH LITTLE
SURFACE BASED INSTABILITY WE PREFER TO SHOW ONLY LIGHT RAINS AT
THIS TIME. VFR CONDITIONS WILL RETURN AFTER 17Z WEDNESDAY.
KSAV...THE TERMINAL WILL EXPERIENCE MVFR OR LOWER CONDITIONS MUCH
OF THE TIME TONIGHT INTO WEDNESDAY AS A WEAK LOW PRESSURE AND A
STATIONARY FRONT TO THE SOUTH APPROACH LATE TONIGHT INTO WEDNESDAY
MORNING. THE TERMINAL WILL EXPERIENCE PERIODIC RAINS...ALONG WITH
THE CHANCE OF TSRA A FEW HOURS EITHER SIDE OF DAYBREAK. VFR
CONDITIONS WILL RETURN AFTER 17Z.
EXTENDED AVIATION OUTLOOK...LOW PROBABILITIES FOR SUB-VFR CONDITIONS
THROUGH EARLY THURSDAY...ESPECIALLY AT KSAV...AS A STALLED FRONT
LINGERS OVER/NEAR THE AREA. OTHERWISE...VFR CONDITIONS EXPECTED
THROUGH SUNDAY.
&&
.MARINE...
A STATIONARY FRONT ACROSS THE GA WATERS WILL BEGIN TO LIFT
SLIGHTLY NORTH TOWARD THE SC WATERS LATE TONIGHT AS A WAVE OF LOW
PRESSURE IN SE ALABAMA RIDES ALONG THE FRONT INTO SOUTHERN GA
LATE. WINDS WILL REMAIN OUT OF THE NE AND EAST TO THE NORTH OF THE
FRONT...AND VEER AROUND TO THE SOUTH IN LOCATIONS SOUTH OF THE
FRONT. SLIGHT PINCHING WILL OCCUR ACROSS THE NORTHERN SC
WATERS...WHILE LOW LEVEL JETTING WILL IMPACT THE GA WATERS
LATE. HOWEVER...WINDS AND SEAS WILL STILL REMAIN ANY SCA
CONDITIONS.
WEDNESDAY THROUGH SUNDAY...A STATIONARY FRONT WILL
REMAIN ACROSS THE SOUTHERN PART OF THE AREA INTO THURSDAY...BEFORE
HIGH PRESSURE BUILDS IN FROM THE NORTHWEST AND PUSHES THE FRONT
SOUTH OF THE AREA. NORTHEAST WINDS WILL BE COMMON NORTH OF THE
FRONT WHILE SOUTHWEST WINDS OF PREVAIL SOUTH OF THE FRONT. ALONG
AND NEAR THE FRONT...WIND SPEEDS WILL GENERALLY BE AT OR BELOW 10
KNOTS. WELL AWAY FROM THE FRONT...WINDS WILL GENERALLY BE FROM 10
TO 20 KNOTS. SEAS AT OR BELOW 5 FEET WILL BE COMMON ON
WEDNESDAY...DIMINISHING TO AOB 3 FEET BY FRIDAY AND THEN
PERSISTING THROUGH SUNDAY.
