S. coastline, resulted in a tight pressure gradient across southern South Carolina and Southeast Georgia.
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.
Strengthening High pressure over New England and low pressure off the Southeast U.S. coastline, resulted in a tight pressure gradient across southern South Carolina and Southeast Georgia. Strong Northeast winds and High Astronomical Tides combined to produce significant Beach Erosion across the region.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, SC wrote its last area forecast discussion before the first event at Sep 29, 8:50 PM EST, 3 hours 10 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
950 PM EDT SAT SEP 29 2007
.SYNOPSIS...
STRONG HIGH PRESSURE WILL DOMINANT THE REGION THROUGH EARLY NEXT WEEK. A
TROUGH OF LOW PRESSURE WILL DEVELOP OFF THE SOUTHEAST COAST EARLY
NEXT WEEK AND MAY MOVE TOWARD THE COAST BY MID WEEK.
&&
.NEAR TERM /TONIGHT/...
CLEAR SKIES WILL CONTINUE THROUGH THE NIGHT AS A RIDGE OF HIGH
PRESSURE REMAINS OVER THE CWA. A STRONG PRESSURE GRADIENT REMAINS ALONG
THE IMMEDIATE GA COASTLINE WHILE WINDS ARE BEGINNING TO BECOME
LIGHT INLAND WHERE THE EFFECTS OF THE GRADIENT HAVE LESSONED. WITH
LIGHT WINDS...RADIATIONAL COOLING HAS TAKEN PLACE AND TEMPS ARE
RAPIDLY DROPPING. THIS IN COMBINATION WITH VERY DRY AIR SEEN ON
WATER VAPOR IMAGERY AND THE 00Z SOUNDING SUGGEST LOWS IN THE LOWER
50S INLAND FOR OUR SC AND GA COUNTIES. DEWPTS UPSTREAM REMAIN IN THE
UPPER 40S AND ARE EXPECTED TO PUSH INTO THE REGION LATER TONIGHT.
IT IS POSSIBLE THAT A FEW AREAS MAY FALL INTO THE UPPER 40S
TONIGHT...ESPECIALLY OVER INLAND SC COUNTIES WHERE THE DRIEST AIR
SHOULD BE EXPERIENCED.
A SMALL POCKET OF MID TO UPPER 50 DEWPTS REMAINS IN OUR GA
COUNTIES TONIGHT. THIS WILL ALLOW TEMPS TO REMAIN SOMEWHAT HIGHER
ALONG OUR COASTAL GA COUNTIES TONIGHT EVEN THOUGH SOME DRYING WILL
CONTINUE TO PENETRATE THE CWA. LOCATIONS SHOULD SEE TEMPS IN THE
UPPER 50S EXCEPT ALONG THE IMMEDIATE GA COAST WHERE MID 60S ARE
EXPECTED. HAVE ADJUSTED LOW TEMPS AND LOWERED WINDS MAINLY INLAND
BASED ON CURRENT TRENDS.
&&
.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
THE EARLY FALL LIKE WEATHER WILL PERSIST INTO SUNDAY NIGHT. LOW-
LVL THICKNESSES ARE FORECAST TO BE SEVERAL METERS LOWER THAN TODAY...
SO EXPECT TEMPS TO TOP OUT AROUND 81-82 DEGS...EXCEPT UPPER 70S
ALONG THE COAST. TEMPS MAY BEGIN TO MODERATE SOME SUN NIGHT AS
WINDS VEER MORE EASTERLY IN RESPONSE TO LARGE HIGH PRESSURE
SHIFTING OFF THE NE U.S. COAST. SKIES WILL REMAIN CLEAR TO MOSTLY
CLEAR.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
MUCH UNCERTAINTY IN THE EXTENDED PERIODS ONCE AGAIN THIS AFTERNOON.
GUIDANCE IS IN GENERAL AGREEMENT THAT AN INVERTED TROUGH OR WEAK
AREA OF LOW PRESSURE WILL DEVELOP IN THE VICINITY OF THE BAHAMAS ON
MONDAY...AND THIS SEEMS REASONABLE GIVEN LOWER PRESSURES AND PLENTY
OF CONVECTION CURRENTLY RESIDING IN THAT REGION. BIG QUESTION IS
WHERE THIS INVERTED TROUGH OR LOW PRESSURE SYSTEM WILL END UP
TRACKING FOR THE MIDDLE TO LATTER PART OF NEXT WEEK. MEDIUM RANGE
GUIDANCE IS ALL OVER THE PLACE...WITH THE ECMWF/UKMET/NAM/NOGAPS
SHIFTING THE SYSTEM WESTWARD ACROSS THE FLORIDA PENINSULA AND INTO
THE GULF OF MEXICO. THE CANADIAN ON THE OTHER HAND RACES THE SYSTEM
QUICKLY NORTHWARD UP ALONG THE EASTERN SEABOARD EARLY NEXT WEEK AND
INTO THE CANADIAN MARITIMES BY MID TO LATE NEXT WEEK.
MEANWHILE...THE GFS SPLITS THE SYSTEM IN TWO...WITH SOME ENERGY
TRANSLATING WESTWARD INTO THE GULF OF MEXICO...AND ANOTHER PIECE OF
ENERGY LIFTING NORTHWARD WELL OFF THE EASTERN SEABOARD. TO MAKE
THINGS EVEN MORE COMPLICATING...THE MOST TRUSTED MEDIUM RANGE
GUIDANCE /GFS AND ECMWF/ HAVE BEEN REMARKABLY CONSISTENT FROM RUN TO
RUN. WILL ONCE AGAIN LEAN TOWARD GUIDANCE CONSENSUS AND FAVOR THE
ECMWF/UKMET SOLUTION.
AS FOR FORECAST DETAILS...EXPECT HIGH PRESSURE TO REMAIN THE
DOMINANT WEATHER FEATURE ACROSS THE REGION MONDAY AND MONDAY
NIGHT...AND ASIDE FROM A FEW COASTAL SHOWERS PUSHING IN OFF THE
ATLANTIC INTO COASTAL GEORGIA ZONES...EXPECT RAIN FREE WEATHER
ACROSS THE AREA. FOLLOWING THE PREFERRED SOLUTION...THE SYSTEM OVER
THE BAHAMAS WILL RETROGRADE WESTWARD OVER THE FL PENINSULA ON MON
NIGHT AND TUE...THEN INTO THE GULF OF MEXICO WEDNESDAY AND THURSDAY.
THIS WILL ALLOW THE INVERTED TROUGH EXTENDING NORTHEASTWARD FROM THE
SYSTEM TO APPROACH THE COAST OF THE SOUTHEAST UNITED STATES. WITH
INCREASING DEEP LAYER MOISTURE AND FLOW OFF THE ATLANTIC...FEEL
UNCOMFORTABLE GOING WITH A DRY FORECAST...SO WILL MENTION SLIGHT
CHANCE OR LOW CHANCE POPS ACROSS THE REGION TUESDAY THROUGH
THURSDAY. AS THE AREA OF LOW PRESSURE CONTINUES TO PUSH WESTWARD
THROUGH THE GULF OF MEXICO FRIDAY AND SATURDAY...HIGH PRESSURE IS
EXPECTED TO BUILD BACK INTO THE SOUTHEAST UNITED STATES FROM THE
NORTH. THEREFORE...WILL MAINTAIN A RAIN FREE FORECAST FRIDAY AND
SATURDAY. TEMPERATURES THROUGH THE EXTENDED ARE EXPECTED TO RUN
SLIGHTLY ABOVE CLIMATOLOGY.
&&
.AVIATION /02Z SUNDAY THROUGH THURSDAY/...
18Z GUIDANCE SUGGESTS LLWS WILL BE A BIT MORE MARGINAL AND WILL
OMIT BUT MAINTAIN VIGIL FOR SUSTAINED DECOUPLING AT BOTH KCHS AND
KSAV TAF SITES. ENE WINDS WILL OCNLY GUST HIGHER THAN SUSTAINED
15-20 KT ON SUNDAY...ESPECIALLY AT KSAV. OTHERWISE...VFR CONDITIONS
WILL PREVAIL THROUGH SUNDAY.
EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL GENERALLY PREVAIL
INTO THE MIDDLE OF NEXT WEEK.
&&
.MARINE...
WINDS HAVE DIMINISHED A BIT AROUND SUNSET AS SUSPECTED EARLIER...
BUT STILL SHOULD INCREASE STEADILY OVERNIGHT AS THERMAL AND
PRESSURE GRADIENTS TIGHTEN IN RESPONSE TO STRONG INLAND COOLING.
EXPECT WINDS TO INCREASE TO 25-30 KT OVER MOST WATERS WITH THE
POTENTIAL FOR GALES DEVELOPING ACROSS THE GA OFFSHORE WATERS SUN
DUE TO FREQUENT GUSTS TO 35 KT. LATER SHIFTS MAY NEED TO ISSUE A
GALE WARNING AT SOME POINT IF STRONG PINCHING OR SURGING DEVELOPS.
HIGH PRESSURE WILL BEGIN TO WEAKEN OVER THE NORTHWEST ATLANTIC
MONDAY AND TUESDAY. A TROUGH OF LOW PRESSURE MAY APPROACH THE WATERS
MID WEEK...WITH HIGH PRESSURE THEN BUILDING BACK INTO THE AREA FROM
THE NORTH BY THE END OF THE UPCOMING WORK WEEK. PINCHED GRADIENT
FLOW AND PERSISTENT LONG NORTHEASTERLY FETCH...IS EXPECTED TO KEEP
SMALL CRAFT ADVISORIES GOING FOR ALL WATERS WITH THE EXCEPTION OF
CHARLESTON HARBOR MONDAY THROUGH TUESDAY NIGHT. SEAS WILL LIKELY BE
SLOWER TO SUBSIDE ACROSS THE OUTER GEORGIA WATERS...SO WILL KEEP THE
SMALL CRAFT ADVISORY GOING THROUGH WEDNESDAY NIGHT.
LAKE WINDS...WINDS HAVE BEEN SLUGGISH TO RESPOND AS YET ON LAKE
MOULTRIE BUT MIXING PROFILES WILL BE INCREASING SIGNIFICANTLY OVER
THE NEXT COUPLE OF HOURS...THUS WIND ADVISORY FOR LAKE MOULTRIE
CONTINUES UNTIL 11 AM SUNDAY.
RIP CURRENTS...A MODERATE RIP CURRENT RISK WILL CONTINUE THROUGH
SUNDAY WITH AN ENHANCED RIP CURRENT RISK INTO TUE. WILL KEEP THE
RISK JUST BELOW HIGH RISK SINCE INFLUENCES FROM THE FULL MOON AND
LUNAR PERIGEE ARE DIMINISHING. WE WILL CONTINUE TO MONITOR THIS
HOWEVER.
&&
.TIDES/COASTAL FLOODING...
LATEST TRENDS AND TIDAL DEPARTURES HEADED TOWARD HIGH TIDE LATE
THIS EVENING SUGGEST LEVELS AT CHARLESTON AND FORT PULASKI WILL
FALL BELOW SHLW COASTAL FLOOD CRITERIA. WE WILL CANCEL THE COASTAL
FLOOD ADVISORY THIS EVENING AND WILL CONTINUE TO FOCUS ON THE
HIGH TIDE ON SUN.
THAT HIGH TIDE SUN MORNING SHOULD BE THE HIGHEST SO FAR FOR THIS
EVENT. TIDAL DEPARTURES WITH TONIGHT/S HIGH TIDE CYCLE WILL LIKELY
YIELD CLUES ON WHETHER COASTAL FLOOD WARNING CRITERIA WILL BE MET.
IT SHOULD BE NOTED HOWEVER THAT WATER WAS ALREADY REPORTED AT THE
DUNE LINES AT SEVERAL LOCATIONS WITH THIS MORNING/S HIGH TIDE...THUS
A WARNING COULD BE JUSTIFIED PURELY ON IMPACTS ALONE AND NOT JUST ON
A LONE TIDE READING. THE LAST SIGNIFICANT COASTAL FLOOD EVENT IS A
GOOD EXAMPLE OF THIS WHERE CHARLESTON HARBOR REACHED 7.8 FT MLLW.
WARNING CRITERIA IS 8 FT MLLW IN THE HARBOR AND 10 FT MLLW AT FT.
PULASKI...HOWEVER NUMEROUS STREET WERE REPORTED CLOSED AND/OR
FLOODED ALONG THE LOWER SOUTH CAROLINA COAST...PARTICULARLY IN
DOWNTOWN CHARLESTON AND ON EDISTO BEACH WHERE SEVERAL HOMES FELL
INTO THE OCEAN.
AT THIS JUNCTURE...THINK IT BEST TO MAINTAIN THE COASTAL FLOOD
WATCH FOR THE ENTIRE COAST FOR SUN MORNING/S HIGH TIDE AND LET
SUBSEQUENT SHIFTS GET A BETTER HANDLE ON TIDAL TRENDS TO SEE IF
THE WATCH NEEDS TO BE UPGRADED TO A COASTAL FLOOD WARNING.
REPORTS FROM TYBEE ISLAND INDICATE BREAKERS OF 5-6 FT ARE
OCCURRING ALONG THE BEACHES OF CHATHAM COUNTY...WITH SIMILAR
CONDITIONS LIKELY OCCURRING ACROSS THE REMAINDER OF N COASTAL GA.
WILL EXTEND THE HIGH SURF ADVISORY THROUGH EARLY MONDAY MORNING.
CONDITIONS ARE MORE BORDERLINE ACROSS S COASTAL SC WHERE WINDS ARE
RUNNING MORE PARALLEL TO SHORE. REPORTS OUT OF FOLLY BEACH
INDICATE BREAKERS ARE RUNNING ABOUT 2-3 FT WITH OCCASIONALLY
HIGHER SETS. THUS WILL NOT EXTEND THE ADVISORY NORTH JUST YET. WE
WILL CONTINUE TO MONITOR.
