With a strong area of high pressure positioned north of the region and ridging down the east side of the Appalachian Mountains, a tight pressure gradient developed along the South Carolina and Georgia coastline. An area of strong gradient winds occurred, especially along coastal Georgia, in response to the tight pressure gradient and strengthening low level jet.
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.
The episode as NWS CHS wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1255 PM EDT SUN OCT 9 2011
.SYNOPSIS...
STRONG HIGH PRESSURE TO THE NORTH OF THE REGION WILL WEAKEN INTO
THE FIRST PART OF THE UPCOMING WEEK. MEANWHILE...LOW PRESSURE WILL
DEVELOP SOUTH OF THE REGION TODAY...AND THIS LOW COULD EVENTUALLY
LIFT NORTHEAST TO IMPACT THE REGION EARLY TO MID WEEK. A COLD FRONT
WILL PASS OFF THE COAST LATE WEEK FOLLOWED BY HIGH PRES NEXT WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
NO MAJOR CHANGES WERE MADE TO THE GRIDS/TEXT PRODUCTS FOR THE
EARLY AFTERNOON FORECAST PACKAGE. WINDS ARE STEADILY INCREASING
ALONG THE CHARLESTON AND COLLETON COUNTY COASTS...AND WE ARE
MONITORING CONDITIONS THERE FOR A POSSIBLE EXPANSION OF THE WIND
ADVISORY. SHOWERS CONTINUE TO STREAM INLAND FROM OFF THE ATLANTIC.
THE PLACEMENT OF THE HIGHEST POPS...UP TO 70 PERCENT..LOOKS GOOD
ACROSS THE SOUTHERN PARTS OF THE FORECAST AREA.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
THE UPPER LEVEL RIDGE WILL CONTINUE TO SHIFT INTO THE WESTERN
ATLANTIC TONIGHT AS AN UPPER LEVEL LOW OVER THE EASTERN GULF OF
MEXICO LIFTS CLOSER TO THE GULF COAST. SURFACE HIGH PRESSURE WILL
REMAIN IN PLACE TO THE NORTH...WITH SOME INDICATION THAT A WEAK
WAVE OF LOW PRESSURE MAY TRY TO DEVELOP ALONG A BROAD TROUGH SOUTH
OF THE REGION. MOISTURE WILL DEEPEN SIGNIFICANTLY FROM THE SOUTH
TONIGHT...AS SHORT WAVE ENERGY OVERSPREADS THE AREA AND STRONG
DIVERGENCE DEVELOPS ALOFT. THIS WILL RESULT IN SHOWERS BECOMING
NUMEROUS TO WIDESPREAD ACROSS MOST OF THE FORECAST AREA...WITH THE
GREATEST COVERAGE IN SOUTHEAST GEORGIA WHERE THE RAIN CAN BECOME
HEAVY AT TIMES LATER TONIGHT. GUSTY WINDS COULD CONTINUE WELL INTO
TONIGHT...ESPECIALLY ALONG THE COAST. CURRENTLY...A WIND ADVISORY
WILL REMAIN IN EFFECT UNTIL 8 PM FOR THE SOUTHEAST GEORGIA COASTAL
ZONES. THIS MAY NEED TO BE EXTENDED THROUGH THE REMAINDER OF THE
NIGHT AND POSSIBLY EXPANDED NORTHWARD TO INCLUDE THE SOUTHEAST
SOUTH CAROLINA COAST.
THE MAIN CONCERN CONTINUES TO REVOLVE AROUND HEAVY RAINFALL POTENTIAL
MON AND TUE AS A VERY COMPLEX SYNOPTIC PATTERN CONTINUES WITH SEVERAL
MID LEVEL DISTURBANCES TO MOVE N THROUGH THE SE STATES AND A RECIPE
FOR VERY STRONG LOW LEVEL/DEEP MOIST CONVERGENCE. CONFIDENCE IN
MODEL SOLUTIONS REMAINS LOW WITH EVOLUTIONS AND TRANSLATIONS OF
LOW PRES TO OUR S GIVEN INHERIT COMPLEXITIES WITH THIS PATTERN.
CATEGORICAL POPS WILL BE ACCOMPANIED BY WINDY CONDITIONS CONTINUING
ALONG COASTAL ZONES ON MON WITH WIND ADVISORIES POSSIBLE ALL
COASTAL AREAS AS THE GRADIENT CONTINUES TO TIGHTEN. LIKELY POPS
ON TUE WITH A CHANCE THAT HEAVY RAINS COULD LINGER.
SEVERE WEATHER POTENTIAL MONDAY IS VERY TRICKY AS DEEP LAYERED
INSTABILITY HUGGING THE COAST AND OVERALL CONFIDENCE IS LOW ON
JUST ABOUT ANY MESOSCALE DETAIL AT THIS POINT. THERE IS PLENTY
OF SHEAR AND LOW LEVEL HELICITY AND CANNOT RULE OUT ISOLATED
SEVERE WEATHER OR A TORNADO. OVERALL...WE THINK THE GRADIENT WINDS
WILL TURN OUT TO BE A MORE SIGNIFICANT PLAYER AND SIMILAR TO AREAS
IN N FLORIDA...THE EVENTUAL COMBINATION OF SATURATED SOILS AND GUSTY
WINDS COULD EVEN SPELL SOME DAMAGE TO WEAKER TREES ALONG SOME PART
OF OUR COASTAL AREAS.
BY WED...STILL PLENTY OF WEAK LOW PRES WAVES EXPECTED TO PASS
ALONG THE BAROCLINIC ZONE JUST OFF THE COAST BUT A MUCH WEAKER
PRES GRADIENT IS EXPECTED. RAINFALL COULD BE FAIRLY WIDESPREAD
ACROSS THE FORECAST AREA...BUT MODELS SHOW A LESS FOCUSED REGIME
WITH THE BELT OF DEEP TROPICAL MOISTURE ANTICIPATED TO BE OFF
THE N.
LAKE WINDS...WE HAVE MAINTAINED MARGINAL LAKE WIND ADVISORY TONIGHT
INTO MON. TRICKY LOW LEVEL ENVIRONMENT FOR MIXING BUT THE GEOSTROPHIC
FLOW IS A SOLID 40 KT AT TIMES AND CONDITIONS SHOULD BE QUITE CHOPPY
ON THE SANTEE COOPER LAKES.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
MID WEEK...WE MAINTAINED DECENT CHANCES OF SHOWERS AS UPPER LEVEL
TROUGHING CONTINUES AND A BAROCLINIC BOUNDARY LINGERS SOMEWHERE
ALONG THE COAST. MOISTURE IS NOT AS DEEP AND SHOWERS SHOULD BE
SCATTERED ON WED BUT CONFIDENCE IS LOW AS SPREADS IN SHORT WAVE
TIMING IS SIGNIFICANT ON THE GLOBAL MODELS AND ENSEMBLES. BY LATE
WEEK...A COLD FRONT WILL MOVE THROUGH THE REGION. A FEW SHOWERS MAY
OCCUR AHEAD OF THE FRONT THU...THEN POST FRONT WEATHER FRI INTO THE
SAT WILL LIKELY BE DRY WITH TEMPS NEAR CLIMO.
&&
.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
VFR CONDITIONS ARE EXPECTED TO REMAIN FOR THE AFTERNOON AND MOST OF
THE EVENING AT BOTH KCHS AND KSAV. VFR CONDITIONS ARE EVIDENT
ALONG THE FL GA AND SC COAST. THE DEEPEST MOISTURE LAYER REMAINS
OVER THE ATLANTIC AND IS EXPECTED TO MAKE ITS WAY TO THE COASTAL
REGIONS TONIGHT AS THE BROAD SURFACE TROUGH MAKES ITS WAY TO THE
NORTH. MVFR CONDITIONS LOOK VERY PROBABLE TONIGHT AT KSAV AND A
LITTLE LATER AT KCHS AS LOW LEVEL MOISTURE INCREASES.
SHOWERS WILL CONTINUE TO MOVE ONSHORE DURING THE AFTERNOON AT KSAV
AND KCHS WILL SEE AN INCREASE IN SHOWER COVERAGE LATER TONIGHT. THE
TIMING OF THESE SHOWERS IS VERY DIFFICULT AT THIS TIME...SO OPTED TO
KEEP VICINITY SHOWERS UNTIL THE EARLY MORNING HOURS. AS THE LOW
LEVEL MOISTURE CONTINUES TO INCREASE LATER IN THE MORNING HOURS
HEAVIER RAIN SHOWERS LOOK VERY PROBABLE AT BOTH AIRPORTS. WINDS WILL
CONTINUE TO BE GUSTY AND FROM THE WEST NORTHWEST THROUGH THE
FORECAST PERIOD AS THE PRESSURE GRADIENT CONTINUES TO TIGHTEN.
EXTENDED AVIATION OUTLOOK...PREVAILING MVFR/IFR CONDITIONS ARE
EXPECTED MON THROUGH TUE NIGHT. PERIODIC MVFR CONDITIONS MAY LINGER
INTO WED...BUT EXPECT CONDITIONS TO IMPROVE TO VFR LEVELS BY THU.
SURFACE WINDS WILL BE QUITE GUSTY AT TIMES FROM THE NORTHEAST TONIGHT
THROUGH MON NIGHT. LLWS IS ALSO POSSIBLE AT TIMES THROUGH EARLY
TUE...ESPECIALLY WHEN GUSTS TEND TO SUBSIDE AND LOWER LEVELS
STABILIZE.
&&
.MARINE...
GALE WARNINGS REMAIN IN PLACE FOR ALL WATERS...EXCLUDING THE
CHARLESTON HARBOR WHERE A GALE WATCH HAS BEEN ISSUED FOR TONIGHT.
GUIDANCE FOR FBIS1 CONTINUES TO INCREASE AND NOW SHOWS WINDS
PICKING UP TO NEAR GALE FORCE BY THIS EVENING. A GALE WATCH HAS
BEEN ISSUED FOR THIS REASON. THE WATCH WILL LIKELY BE UPGRADED TO
A GALE WARNING WITH THE LATE AFTERNOON FORECAST PACKAGE...ASSUMING
TRENDS CONTINUE WITH THE 12Z MODEL DATA.
GALES WILL CONTINUE MON AS A VERY TIGHT PRES GRADIENT CONTINUES
THROUGH THE WATERS. THE NAM AND GFS SHOW GALES SUBSIDING OVER
THE SOUTHERN GEORGIA WATERS MON AFTERNOON AS THE GRADIENT PINCHING
TRANSLATES N INTO THE SOUTH CAROLINA WATERS AS PRESSURES LOWER
OFF THE N FLORIDA COAST WITH SECONDARY LOW PRES DEVELOPING. DOUBLE
DIGIT SEAS WILL BE THE NORM...EVEN CLOSER TO THE COAST AS THE
FLOW CONTINUES TO INCREASE.
THE NAM AND GFS SHOW A GRADUAL S TO N IMPROVEMENT BY EARLY TUE
BUT THE ECMWF IS SLOWER AND CONFIDENCE IS FAIRLY LOW. WE TREND
BACK THE GALES MON NIGHT...THE CHARLESTON COUNTY COAST WILL
TEND TO GUST TO GALE LONGER GIVEN THE FORECAST TRENDS. BY MID
WEEK...A WEAKER GRADIENT IS EXPECTED BUT THERE WILL BE LINGERING
SWELL FOR WHILE. LATE WEEK WILL SEE THE FLOW SHIFT MORE OFFSHORE
AND SEAS WILL BE BELOW SCA LEVELS AFTER WED.
RIP CURRENTS...THERE WILL BE A HIGH RISK FOR RIP CURRENTS AT ALL AREA
BEACHES TODAY DUE TO STRONG ONSHORE WINDS...LARGE SWELLS IMPACTING
THE COAST AND AN INCREASED LUNAR INFLUENCE. AN ELEVATED RISK FOR RIP
CURRENTS WILL CONTINUE INTO THE MIDDLE OF NEXT WEEK GIVEN A
CONTINUED STRONG ONSHORE FETCH.
&&
.HYDROLOGY...
A HEAVY RAINFALL EVENT LOOKS TO BE SETTING UP SOMEWHERE ACROSS THE
FORECAST AREA LATE TONIGHT THROUGH TUESDAY. AT THIS POINT...COASTAL
ZONES APPEAR TO HAVE THE BEST CHANCES OF FOR SIGNIFICANT RAINFALL.
THERE REMAINS ENOUGH UNCERTAINTY BOTH TIMING AND THE EXACT LOCATION
WHERE THE HEAVIEST RAINS WILL SET UP TO PRECLUDE ISSUING A FLASH
FLOOD WATCH AT THIS TIME. WE HAVE INTRODUCED RAIN HEAVY AT TIMES
MENTIONS IN OUR GRIDS AND PUBLIC PRODUCTS LATE TONIGHT IN SE
GEORGIA ...SPREADING N ON MONDAY. WILL HOLD OFF ON A WATCH AT THIS
TIME AND CONTINUE TO MENTION THE POTENTIAL FOR HEAVY RAINFALL IN THE
HAZARDOUS WEATHER OUTLOOK.
&&
.TIDES/COASTAL FLOODING...
HIGH SURF...BREAKER HEIGHT MATRIX DATA BASED ON SPECTRAL
BREAKDOWNS FROM BUOYS 41004 AND 41008 SUGGEST BREAKER HEIGHTS IN
THE SURF ZONE ARE RUNNING 4-6 FT ALONG THE SOUTHERN SOUTH CAROLINA
COAST TO 5-8 FT ALONG NORTH COASTAL GEORGIA. THE HIGH SURF
ADVISORY WILL BE MAINTAINED THROUGH TUESDAY MORNING.
COASTAL FLOODING...BEGINNING EARLY MONDAY MORNING AND CONTINUING INTO
THE EARLY/MIDDLE PORTION OF NEXT WEEK...INCREASING ONSHORE FLOW
WILL INCREASE CHANCES FOR SHALLOW SALT WATER FLOODING AND BEACH
EROSION DURING HIGH TIDE CYCLES WITH THE LONG DURATION NE FLOW
EVENT. COASTAL FLOOD WATCHES AND/OR ADVISORIES MAY EVENTUALLY BE
NEEDED.
