An area of low pressure developed over the northeastern Gulf of Mexico and moved across Florida toward the southeast coastline. With an area of high pressure positioned to the north of the region, a tight pressure gradient developed across the southeast Georgia coastal region.
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.
An area of low pressure developed over the northeastern Gulf of Mexico and moved across Florida toward the southeast coastline. With an area of high pressure positioned to the north of the region, a tight pressure gradient developed across the southeast Georgia coastal region. Strong gradient winds occurred during the day, especially during peak mixing in the afternoon hours.
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 Oct 10, 6:59 AM EST, 14 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
759 AM EDT MON OCT 10 2011
.SYNOPSIS...
STRONG HIGH PRESSURE TO THE NORTH OF THE REGION WILL WEAKEN TODAY.
MEANWHILE...LOW PRESSURE WILL CONTINUE TO MOVE ACROSS FLORIDA.
ADDITIONAL WAVES OF LOW PRESSURE COULD EVENTUALLY LIFT NORTHEAST TO
IMPACT THE REGION THROUGH MID WEEK. A COLD FRONT WILL PASS OFF THE
COAST LATE WEEK FOLLOWED BY HIGH PRESSURE NEXT WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SURFACE OBSERVATIONS AND RADAR IMAGERY FROM KJAX AND KMLB INDICATE
A 1003 MB LOW PRESSURE SYSTEM OVER NORTHERN FLORIDA NEAR GAINESVILLE
AS OF ABOUT 8 AM. A TROUGH EXTENDS NORTHEAST FROM THIS LOW TO A
POSITION BETWEEN SAINT SIMONS ISLAND AND DARIEN THEN CONTINUES TO
HUG THE GEORGIA AND SOUTH CAROLINA COAST JUST OFFSHORE.
MEANWHILE...STRONG HIGH PRESSURE CONTINUES TO BUILD SOUTH ACROSS
THE REGION FROM THE MID-ATLANTIC. IN THE MID AND UPPER LEVELS OF
THE ATMOSPHERE...A RIDGE CONTINUES TO DRIFT SLOWLY OFF THE MID-
ATLANTIC COAST WHILE A CLOSED LOW OVER THE NORTHEAST GULF OF
MEXICO AND NORTHERN FLORIDA SLOWLY LIFTS NORTHWARD.
MODELS ARE STILL HAVING A DIFFICULT TIME RESOLVING THE LOW
PRESSURE SYSTEM OVER FLORIDA...RESULTING IN SOME UNCERTAINTY TO
THE TRACK FORECAST AS WELL AS THE OVERALL TIMING OF SYNOPTIC
FEATURES. OVERALL...IT APPEARS THAT THIS LOW WILL SLOWLY LIFT
NORTH THEN NORTHWEST...REACHING THE NORTHEAST GULF OF MEXICO BY
THE END OF THE DAY. THIS COULD CAUSE THE TROUGH TO SHIFT
ONSHORE...ESPECIALLY IN SOUTHEAST GEORGIA AND PERHAPS ALONG THE
IMMEDIATE SOUTH CAROLINA COAST. MEANWHILE...THERE IS SOME
INDICATION FROM THE NAM...LOCAL 4KM WORKSTATION WRF AND THE
CANADIAN THAT ANOTHER WEAK AREA OF LOW PRESSURE MAY TRY TO DEVELOP
OFF THE SOUTHEAST U.S. AND RACE NORTH-NORTHWEST TOWARD THE
COAST. THIS CERTAINLY SEEMS REASONABLE GIVEN A WEAKNESS IN THE
SURFACE PRESSURE FIELDS OVER THAT AREA THIS MORNING.
A PLUME OF DEEP TROPICAL MOISTURE CONTINUES TO STREAM INTO THE
REGION IN THE SOUTHEAST FLOW BETWEEN THE UPPER LEVEL
SYSTEMS...RESULTING IN PRECIPITABLE WATER VALUES IN EXCESS OF 2
INCHES ACROSS THE AREA. FREQUENT SHOWERS WILL CONTINUE ACROSS THE
ENTIRE FORECAST AREA TODAY...WITH THE RAIN TORRENTIAL AT TIMES.
WHILE THE OVERALL FORECAST QPF VALUES ARE SLIGHTLY LOWER THAN
PREVIOUSLY THOUGHT...WILL MAINTAIN THE FLASH FLOOD WATCH FOR ALL
COASTAL AREAS AND A FEW COUNTIES JUST INLAND FROM THE COAST
THROUGH THIS EVENING. THE GREATEST THREAT WILL COME ALONG THE
COAST IF HEAVY RAINFALL COINCIDES WITH THE TIME OF HIGH TIDE.
WHILE THE OVERALL RISK FOR THUNDERSTORMS APPEARS RATHER LOW AND
MAINLY CONFINED TO COASTAL AREAS...STRONG WIND SHEAR AND
INCREASING HELICITY VALUES NORTH OF THE LOW CIRCULATION COULD
RESULT IN A THREAT FOR ISOLATED TORNADOES TODAY ACROSS PARTS OF
THE AREA. THE THREAT WILL BE ENHANCED IF THE COASTAL TROUGH
IS ABLE TO SHIFT ONSHORE...WHICH APPEARS MOST LIKELY TO OCCUR
ACROSS NORTH COASTAL GEORGIA...WHERE THE STORM PREDICTION CENTER
HAS ISSUED A TORNADO WATCH UNTIL 1 PM THIS AFTERNOON. THE WATCH
MAY NEED TO BE EXTENDED IN TIME AND/OR EXPANDED FATHER NORTH
DEPENDING ON IF THE TROUGH MAKES BETTER INLAND PROGRESS.
STRONG GRADIENT WINDS ARE EXPECTED ACROSS THE AREA ONCE AGAIN
TODAY. WITH GALES OCCURRING OVER THE ADJACENT COASTAL WATERS AND
FAVORABLE ONSHORE WIND TRAJECTORIES...WINDS WILL BE STRONGEST AT
THE BEACHES AND A WIND ADVISORY REMAINS IN EFFECT THROUGH THIS
AFTERNOON FOR ALL COASTAL ZONES WHERE GUSTS OF 45 MPH ARE EXPECTED
AT TIMES. GUSTS COULD BE UP TO 55 MPH IN SQUALLS AS THEY MOVE
ONSHORE...POSSIBLY EVEN AFFECTING AREAS INLAND OF THE WIND
ADVISORY IF THE TROUGH SHIFTS INLAND AND BETTER MIXING PROFILES
DEVELOP.
TEMPERATURES SHOULD BE HELD INTO THE LOWER TO MID 70S TODAY WITH
EXTENSIVE CLOUD COVER AND PRECIPITATION EXPECTED.
LAKE WINDS...A LAKE WIND ADVISORY REMAINS IN EFFECT FOR LAKE
MOULTRIE DUE TO THE STRONG GRADIENT WINDS IN PLACE.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
TONIGHT...THE LOW PRESSURE SYSTEM IS EXPECTED TO LINGER OVER THE
NORTHEAST GULF OF MEXICO OR NEAR THE BIG BEND REGION OF FLORIDA.
MEANWHILE...THERE CONTINUES TO BE SOME INDICATION THAT A SECONDARY
AREA OF LOW PRESSURE WILL RACE TOWARD THE SOUTHEAST U.S. COAST
FROM NORTH OF THE BAHAMAS LATE TONIGHT. THIS MESOSCALE FEATURE CAN
HAVE SIGNIFICANT IMPACT ON THE AREA IF IT DOES DEVELOP...BUT THE
TRACK/TIMING IS HIGHLY UNCERTAIN AS IT HAS YET TO ORGANIZE.
HOWEVER...INCREASED WIND FIELDS AND ENHANCED LOW LEVEL CONVERGENCE CAN
ALL BE ASSOCIATED WITH IT...BRINGING THE POTENTIAL FOR MORE WINDY
CONDITIONS AND HEAVY RAINFALL OVER PARTS OF THE AREA. THE FORECAST
WILL INDICATE NUMEROUS TO WIDESPREAD FREQUENT SHOWERS THIS
EVENING...WITH THE COVERAGE DIMINISHING FROM THE SOUTH OVERNIGHT.
ON TUE...MESOSCALE DETAILS WILL AGAIN INFLUENCE THE SYNOPTIC
PATTERN WITH SIGNIFICANT MID AND UPPER LEVEL TROUGHING IN PLACE
AND DEEP MOISTURE PROFILES FOR AT LEAST THE FIRST HALF OF THE
DAY ACROSS MUCH OF SOUTH CAROLINA. A MID LAYER DRY SLOT COULD PUNCH
INTO GEORGIA ALLOWING FROM SOME BREAKS IN THE CLOUDS AND POTENTIAL
AFTERNOON INSTABILITY. WE PLAYED WIDESPREAD RAINS WITH A
SLIGHT CHANCE OF EARLY TSTMS IN OUR SOUTH CAROLINA ZONES AND
SCATTERED TO NUMEROUS SHOWERS A FEW TSTMS IN SE GEORGIA WITH POPS
GRADUATED HIGHER FROM S TO N. LOW LEVEL WIND FIELDS ARE NOT NEARLY
AS STRONG BUT WILL NEED TO WATCH FOR POTENTIAL OF SEVERE WEATHER
ONLY IF THE COASTAL FRONT CAN REMAIN INLAND AND MODELS DO NOT
SEEM TO HAVE A GOOD GRIP ON IT/S LOCATION OR PROGRESSION AT THIS
POINT.
SURFACE LOW PRES WAVES ALONG THE COASTAL FRONT APPEAR TO PULL AWAY
WED NIGHT AND THU AND DURING THESE PERIODS WE HAVE TRIMMED
BACK POPS TO MAINLY SLIGHT CHANCES. A FAIRLY STRONG SHORT WAVE
WILL BE APPROACHING FROM THE WNW ON THU BUT DEEPER LAYERED W FLOW
SHOULD KEEP ANY PRECIP COMING IN FROM THE W GENERALLY SPARSE.
LAKE WINDS...A LAKE WIND ADVISORY REMAINS IN EFFECT INTO THIS EVENING FOR
LAKE MOULTRIE DUE TO THE STRONG GRADIENT WINDS IN PLACE.
&&
.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
A COLD FRONT WILL MOVE THROUGH THE REGION THU NIGHT. POST-FRONT
NOT TOO MUCH COOL AIR BEHIND THE FRONT BUT CERTAINLY A DRIER AIR
MASS ACCOMPANYING SURFACE HIGH PRES BUILDING IN FROM THE W.
THE COMBINATION OF DOWNSLOPE FLOW AND WARMING 850 MB TEMPS
OVER THE WEEKEND LED US TO INCREASE MAX TEMPS INTO THE LOWER
80S MANY AREAS. OVERNIGHT LOWS WILL BE FAIRLY CLOSE TO CLIMO
WITH GOOD RADIATIONAL COOLING.
&&
.AVIATION /12Z MONDAY THROUGH FRIDAY/...
CONDITIONS WILL CONTINUE TO STEADILY DETERIORATE AT THE TERMINALS
AS DEEP TROPICAL MOISTURE OVERSPREADS THE AREA AHEAD OF A LOW
PRESSURE SYSTEM LIFTING INTO THE NORTHEAST GULF OF MEXICO FROM
NORTHERN FLORIDA. FREQUENT SHOWERS ARE EXPECTED TO SHIFT INLAND
THROUGH THIS EVENING...WITH RAIN HEAVY AT TIMES. GRADIENT WINDS WILL
REMAIN RATHER STRONG THROUGH THIS EVENING WITH HIGH PRESSURE
SITUATED NORTH OF THE REGION AND THE LOW TO THE SOUTH. WIND GUSTS
WILL FREQUENTLY REACH 25-30 KT AT THE TERMINALS...ESPECIALLY FROM
MID-MORNING THROUGH MOST OF THE AFTERNOON...BUT GUSTS UPWARDS OF
45-50 KT ARE POSSIBLE IN SQUALLS WHICH WILL BE MORE DIFFICULT TO
TIME. LOW LEVEL WIND SHEAR WILL ALSO BE A CONCERN THROUGH MID-
MORNING IF WIND GUSTS ARE LESS FREQUENT. CONDITIONS WILL BE
PREDOMINATELY MVFR OR IFR AT THE TERMINALS THROUGH 12Z TUESDAY.
EXTENDED AVIATION OUTLOOK...THERE COULD BE SOME WIDESPREAD
MVFR/IFR PERIODIC MVFR CONDITIONS MAY LINGER INTO WED...BUT EXPECT
CONDITIONS TO IMPROVE TO VFR LEVELS BY THU.
&&
.MARINE...
BUOY AND COASTAL OBSERVATIONS INDICATE HAZARDOUS MARINE CONDITIONS ARE ONGOING
ACROSS THE WATERS THIS MORNING WITH FREQUENT GUSTS TO GALE FORCE
BEING OBSERVED AT THE OFFSHORE BUOYS. IF A COASTAL TROUGH HUGGING
THE COAST SHIFTS INLAND...THE HIGHER GUSTS WILL BE REALIZED ALONG
THE IMMEDIATE COAST AS WELL. OUTSIDE OF THE GRADIENT
WINDS...SQUALLS WILL BE CAPABLE OF PRODUCING WIND GUSTS OF NEAR 50
KT AT TIMES. NEEDLESS TO SAY...A GALE WARNING WILL BE MAINTAINED
FOR ALL COASTAL WATERS INTO TONIGHT...INCLUDING THE CHARLESTON
HARBOR. WINDS WILL THEN DIMINISH LATER TONIGHT AS THE STRONGEST
PRESSURE GRADIENT SHIFTS NORTH OF THE AREA.
A LOW CONFIDENCE MARINE FORECAST GIVEN THE SPREAD OF SOLUTIONS
CONCERNING THE COASTAL FRONT AND RIPPLES OF LOW PRES EXPECTED TO
RIDE ALONG IT INTO EARLY WED. SMALL CRAFT ADVISORIES ON TUE
MAY BE LOWERED FROM S TO N INTO MID WEEK AS THE GRADIENT WEAKENS
AND SEAS SLOWLY SUBSIDE. A COLD FRONT WILL APPROACH FROM THE W
THU AND PASS OFF THE COAST THU NIGHT. WINDS AFTER MID WEEK WILL
HAVE OFFSHORE COMPONENTS AND SURGES LIKELY TO BE BEYOND 20 NM
AND PROBABLY BELOW SCA LEVELS.
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 THE WEEK GIVEN A
CONTINUED STRONG ONSHORE FETCH.
&&
.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...TIDAL ANOMALIES WERE RUNNING 1.0 TO 1.2 FEET
ABOVE PREDICTED LEVELS DURING THE PREVIOUS HIGH TIDE CYCLE. THESE
TIDAL DEPARTURES ARE EXPECTED TO CONTINUE...IF NOT INCREASE
SOME...INTO THIS MORNING/S HIGH TIDE CYCLE GIVEN THE STRONG
NORTHEAST/EAST FETCH THAT IS IN PLACE. THE COMBINATION OF STRONG
WINDS...CURRENT TIDAL DEPARTURES AND ONGOING TIDAL LOADING IN THE
MARSHES UP AND DOWN THE COAST SUGGEST SHALLOW COASTAL FLOODING
WILL LIKELY DEVELOP IN A NUMBER OF PLACES THIS MORNING. IT SHOULD
ALSO BE NOTED THAT THE TIDAL LOADING WILL ACTUALLY RESULT IN THE
HIGHEST TIDE LEVELS ANYWHERE FROM 30 TO 60 MINUTES PAST THE
FORECAST TIME OF HIGH TIDE. A COASTAL FLOOD ADVISORY HAS BEEN
ISSUED FOR ALL COASTAL ZONES FOR MONDAY MORNING/S HIGH TIDE CYCLE
AS A RESULT.
PERSISTENT STRONG ONSHORE FLOW MAY RESULT IN SHALLOW SALT WATER
FLOODING AND BEACH EROSION DURING THE HIGH TIDE CYCLES THROUGH
TONIGHT.
