AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
617 AM EST TUE DEC 1 2009
...STRONG LOW PRESSURE POISED TO IMPACT THE REGION WEDNESDAY AND
WEDNESDAY NIGHT BRINGING A NUMBER OF POTENTIALLY SIGNIFICANT
IMPACTS...
.SYNOPSIS...
HIGH PRESSURE WILL REMAIN ACROSS THE AREA TODAY BEFORE SHIFTING
OFFSHORE TONIGHT. A GULF LOW PRESSURE SYSTEM WILL DEVELOP TUESDAY
AND TUESDAY NIGHT...THEN TRACK NORTHEASTWARD ALONG THE APPALACHIANS
WEDNESDAY AND WEDNESDAY NIGHT. A COLD FRONT WILL SWING THROUGH THE
AREA THURSDAY...FOLLOWED BY HIGH PRESSURE FOR THE END OF THE WEEK
THROUGH NEXT WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
THE INITIAL COLD FRONT IS NOW WELL OFFSHORE WITH COOLER/DRIER AIR
FILTERING INTO THE REGION FROM THE NORTH. THERE HAS BEEN A PERIOD
OF GUSTY WINDS /UP TO 30 MPH AT TIMES/ WITH THE PASSAGE OF THE
FRONT...BUT GUSTS SHOULD DIMINISH OVER THE NEXT SEVERAL HOURS AS
HIGH PRESSURE BUILDS FARTHER INTO THE REGION AND ISALLOBARIC
INFLUENCES WANE. SUNNY SKIES THIS MORNING WILL GIVE WAY TO
INCREASING CIRRUS SPREADING OUT AHEAD OF DEVELOPING LOW PRESSURE
OVER THE WESTERN GULF OF MEXICO. CURRENT TRENDS SUGGEST SKIES WILL
BECOME MOSTLY CLOUDY ACROSS A GOOD CHUNK OF THE FORECAST AREA BY
EARLY-MID AFTERNOON WITH POSSIBLY ONLY THE CHARLESTON TRI-COUNTY
AREA SEEING THE BULK OF THICKEST CIRRUS HOLDING OFF UNTIL AFTER
SUNSET. WEAK COLD AIR ADVECTION THIS MORNING WILL BECOME NEUTRAL
BY EARLY AFTERNOON AS THE APPROACHING SHORTWAVE RIDGE AXIS SHIFTS
OFFSHORE AND THE 925-700MB LAYERED FLOW BACKS MORE SOUTHERLY. WITH
INCREASING CLOUDS EXPECTED DURING PEAK HEATING...EXPECT MOST AREAS
TO ONLY TOP OUT IN THE 61-63 DEGREE RANGE.
&&
.SHORT TERM /WEDNESDAY/...
CONDITIONS WILL RAPIDLY DETERIORATE LATE TONIGHT AS GULF LOW
PRESSURE APPROACHES FROM THE SOUTHWEST. WATER VAPOR IMAGERY SHOWS
A WELL DEFINED BAROCLINIC LEAF ALREADY EVOLVING AHEAD OF THE CUT
OFF LOW SPINNING OVER NORTHERN MEXICO. CYCLOGENESIS IS ALREADY
WELL UNDERWAY OVER THE WESTERN GULF WHERE SURFACE PRESSURES OFF
THE TEXAS COAST HAVE BEEN STEADILY FALLING FOR MUCH OF THE NIGHT.
THE SURFACE LOW WILL CONTINUE TO STEADILY INTENSIFY TODAY AS THE
CUT OFF BEGINS TO KICK OUT AND 200-300MB DIFLUENCE STRENGTHENS
WITHIN THE BAROCLINIC LEAF. MODELS ARE SIMILAR IN TRACKING THE
995MB LOW TO THE WEST WEDNESDAY AFTERNOON WITH AN EVOLVING
COASTAL WARM FRONT MOVING ONSHORE AND THROUGH THE FORECAST AREA
AFTER MIDNIGHT. THE TRAILING COLD FRONT IS ON SCHEDULE TO
APPROACH THE FAR WESTERN ZONES LATE WEDNESDAY AFTERNOON AND WILL
EVENTUALLY PUSH OFFSHORE AFTER SUNSET.
FOR THE FORECAST DETAILS...TEMPERATURES TONIGHT WILL BE EXTREMELY
TRICKY AS MUCH WILL DEPEND ON THE EVENTUAL EVOLUTION OF THE
COASTAL WARM FRONT. THE DEVELOPMENT OF 40-50 KT LOW-LEVEL JET
AND WARM AIR ADVECTING INLAND FROM THE WARMER GULF STREAM WATERS
WITH THE PASSAGE OF THE COASTAL FRONT SUGGEST TEMPERATURES WILL
STEADY OUT AND SLOWLY RISE AFTER MIDNIGHT FOR MOST AREAS. EXPECT
LOWS FROM THE UPPER 40S WELL INLAND TO THE UPPER 50S/NEAR 60 AT
THE COAST TO OCCUR DURING THE MID-LATE EVENING HOURS WITH READINGS
RISING INTO THE LOWER 60S AT THE COAST AND THE LWR-MID 50S WELL
INLAND BY SUNRISE WEDNESDAY. HIGHS WEDNESDAY AFTERNOON WILL BE
TEMPERED SOMEWHAT BY EXTENSIVE CLOUD COVER WITH THE AREA REMAINING
SOLIDLY WITHIN THE WARM SECTOR FOR MUCH OF THE DAY...BUT MOST
LOCALES SHOULD MAKE A RUN FOR THE 70 DEGREE MARK.
STRONG WARM AIR ADVECTION/ISENTROPIC LIFT WILL BEGIN TONIGHT AND
CONTINUE THROUGH WEDNESDAY WITH THE RAIN EXPECTED TO MOVE INTO THE
FAR SOUTHERN ZONES SHORTLY AFTER THE 1-3 AM TIME FRAME. THE DEVELOPING
RAIN SHIELD ASSOCIATED WITH A PRONOUNCED 850MB CONFLUENCE BAND
WILL GRADUALLY SHIFT NORTH LATE TONIGHT THROUGH WEDNESDAY MORNING.
THE SREF CONTINUES TO SHOW GOOD RUN-TO-RUN CONTINUITY ON THE
TIMING OF THIS FEATURE WHICH LEADS TO INCREASED FORECAST
CONFIDENCE. WILL SHOW POPS INCREASING TO 70 PERCENT ACROSS THE FAR
SOUTH TRENDING TO 20-40 PERCENT ACROSS THE FAR NORTHERN ZONES BY
SUNRISE WEDNESDAY. POPS WILL THEN BE INCREASED TO 80-90 PERCENT
WEDNESDAY MORNING WITH THE CORE OF THE RAINS INDUCED BY THE
CONFLUENCE BAND CLEARING THE CHARLESTON TRI-COUNTY AREA BY
LUNCHTIME. BY AFTERNOON...A BELT OF STRONG Q-G FORCING ASSOCIATED
WITH THE REMNANTS OF THE EJECTED UPPER LOW WILL SUPPORT A MUCH
LARGER...HEAVIER AND POTENTIALLY STRONGER BAND OF WIDESPREAD RAIN.
THIS ACTIVITY WILL MOVE INTO THE FAR WESTERN ZONES BY EARLY
AFTERNOON AND OVERSPREAD THE REMAINDER OF THE FORECAST AREA AS THE
DAY PROGRESSES...POTENTIALLY REACHING THE I-95 CORRIDOR PRIOR TO
SUNSET. WILL SHOW POPS AS HIGH AS 100 PERCENT WELL INLAND TRENDING
TO LIKELY POPS ALONG THE SOUTH CAROLINA COAST.
INGREDIENTS APPEAR TO BE COMING TOGETHER FOR A POTENTIALLY
SIGNIFICANT SEVERE WEATHER EVENT. IF THE MODELS ARE CORRECT WITH
THE TEMPERATURE AND BOUNDARY LAYER MOISTURE EVOLUTION...SURFACE
BASED INSTABILITY OF AROUND 400-900 J/KG OF CAPE AND LI/S OF -2 TO
-4C ACROSS THE ENTIRE FORECAST AREA...WITH NO CONVECTIVE INHIBITION
WILL BE REALIZED. THIS COMBINED WITH STRONG MID-LEVEL QG FORCING...
ENTRANCE REGION FORCING FROM A 130+ KT UPPER JET... MID- LEVEL
LAPSE RATES STEEPENING TO BETWEEN 6.5 AND 7.0 C/KM ALONG WITH 0-6
KM BULK SHEAR VALUES OF 65 TO 75 KT...WILL BE SUPPORTIVE OF
ORGANIZED LINEAR CONVECTION WITH OCCASIONAL SUPERCELL STRUCTURES.
WITH 850MB WINDS INCREASING TO AROUND 70 KT PROGGED BY BOTH THE GFS
AND NAM...ENERGY HELICITY INDICES CLIMBING TO AROUND 1...AND 0-1
KM HELICITY VALUES MAXING OUT IN THE 400-500 M2/S2...DAMAGING
STRAIGHT LINE WINDS AND TORNADOES APPEAR TO BE THE PRIMARY SEVERE
WEATHER THREATS WITH MARGINALLY SEVERE HAIL POSSIBLE AS WELL. THE
SPC CONTINUES TO SHOW A SLIGHT RISK FOR THE REGION WEDNESDAY WITH
30 PERCENT PROBABILITIES OF DAMAGING WINDS AND A LARGE HATCHED
AREA FOR SIGNIFICANT SEVERE WEATHER ALONG MUCH OF COASTAL SOUTH
CAROLINA AND GEORGIA. THE POTENTIAL IS CERTAINLY THERE FOR A FEW
STRONG...LONG TRACK TORNADOES. WILL CONTINUE TO MENTION SEVERE
WORDING IN THE ZONES AND FORECAST GRIDS FOR THE ENTIRE FORECAST
AREA.
IN ADDITION TO THE SEVERE WEATHER POTENTIAL...WITH BOUNDARY LAYER
WINDS INCREASING TO AROUND 50 KNOTS WEDNESDAY AFTERNOON AND
WEDNESDAY EVENING...WIND ADVISORIES MAY BE NEEDED FOR PORTIONS OF
THE FORECAST AREA...ESPECIALLY ALONG THE SOUTH CAROLINA COAST. A
LAKE WIND ADVISORY WILL ALSO LIKELY BE NEEDED FOR LAKE MOULTRIE.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
SURFACE LOW AND POTENT UPPER SHORTWAVE WILL CONTINUE TO TRACK
NORTHEAST INTO THE OHIO VALLEY WEDNESDAY NIGHT. THE SPEED OF THE
SYSTEM WILL LARGELY DETERMINE THE POTENTIAL FOR SEVERE WEATHER
INTO THE EVENING HOURS...WITH A SLOWER SYSTEM ALLOWING MORE TIME
FOR STRONG WARM ADVECTION AND DESTABILIZATION. THIS FACTOR IS
UNFORTUNATELY APPARENT IN THE DISAGREEMENT BETWEEN THE THREE MAIN
MODELS. THE SLOW SOLUTION OF THE NAM SUGGESTS A HIGHER SEVERE
POTENTIAL. ENOUGH INSTABILITY PUSHES ONSHORE WEDNESDAY EVENING IN
THE NAM TO SUPPORT STRONG THUNDERSTORM DEVELOPMENT...AND JUST AS
WORRISOME...THE EHI VALUES SUGGEST DECENT TORNADO POTENTIAL
WITHIN THE STRONG SHEAR OF THIS DYNAMIC LOW SYSTEM. THE FASTEST
SOLUTION FROM THE GFS LEAVES A SMALLER WINDOW OF OPPORTUNITY FOR
STRONG CONVECTIVE DEVELOPMENT...ESPECIALLY IN THE EVENING HOURS
WITH THE MODEL PUSHING THE COLD FRONT INTO THE WATERS SHORTLY
AFTER 00Z.
THE ECMWF IS NOT AS SLOW WITH THE LOW PROGRESSION AS THE NAM...BUT
STILL SUGGESTS MORE SEVERE POTENTIAL THAN THE GFS. WILL LEAN
TOWARD THIS MIDDLE GROUND AND MAINTAIN CURRENT FORECAST FOR
WEDNESDAY NIGHT INTO THURSDAY WITH FEW SIGNIFICANT CHANGES. ALTHOUGH
INSTABILITY IS MARGINAL...CURRENT THINKING IS THAT EVEN MEAGER
DESTABILIZATION WILL BE ABLE TO TAP INTO THE IMPRESSIVE SHEAR AND
OVERALL DYNAMICS WITH THIS LOW PRESSURE SYSTEM. WILL CONTINUE TO
ADVERTISE SEVERE WEATHER POTENTIAL WITH THE MAIN HAZARDS DAMAGING
WIND GUSTS AND ISOLATED TORNADOES.
IN ADDITION TO THE SEVERE WEATHER POTENTIAL...WITH BOUNDARY LAYER
WINDS INCREASING TO AROUND 50 KNOTS THROUGH WEDNESDAY
EVENING...WIND ADVISORIES MAY BE NEEDED FOR PORTIONS OF THE
FORECAST AREA...ESPECIALLY ALONG THE SOUTH CAROLINA COAST.
HAVE CONTINUED TO MENTION CATEGORICAL POPS AND A CHANCE FOR
SEVERE THUNDERSTORMS WITH DAMAGING WINDS IN THE FORECAST FOR
WEDNESDAY EVENING...WHILE ALSO MAINTAINING SEVERE WEATHER
DISCUSSION IN THE HAZARDOUS WEATHER OUTLOOK. RAIN AND THUNDERSTORM
POTENTIAL WILL STEADILY DECREASE FROM WEST TO EAST AFTER
MIDNIGHT...AS THE COLD FRONT SHIFTS THROUGH THE AREA. THE FRONT
SHOULD BE OFFSHORE BY THURSDAY MORNING...AND HAVE ENDED MENTION
OF RAIN CHANCES ACCORDINGLY.
EXPECT A COOLING TREND AND RAIN FREE CONDITIONS AT LEAST INTO
SATURDAY. THE MAIN FORECAST UNCERTAINTY FOR LATE WEEK/WEEKEND WILL
BE THE FORMATION OF A WAVE OF LOW PRESSURE OFFSHORE FRIDAY AND
SATURDAY...AS SEEN IN BOTH GFS AND ECMWF. THIS COULD SUPPRESS COLD
ADVECTION LATE IN THE PERIOD. WILL INTRODUCE JUST A SLIGHT CHANCE
OFF SHOWERS FOR MAINLY THE WATERS AND COASTAL AREAS FRIDAY NIGHT
AND SATURDAY. IF THE COASTAL LOW PULLS NORTHEAST OFF THE CAROLINA
COAST AND THE REGION BECOME SITUATED WITHIN SOLID NORTHERLY
FLOW...HIGH TEMPERATURES COULD DROP BACK INTO THE 50S.
&&
.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
VFR CONDITIONS WILL PREVAIL THROUGH THIS AFTERNOON. LOW TO MID-
LEVEL CLOUD COVER WILL QUICKLY THICKEN AFTER SUNSET WITH CIGS
DROPPING TO MVFR AT KSAV BY 04Z AND 08Z AT KCHS. MODELS ARE
TRENDING A BIT FASTER WITH THE TIMING OF THE RAIN DEVELOPING
OVERNIGHT. WILL BRING SOME LOW-END MVFR VSBYS IN -RA TO KSAV BY
MIDNIGHT BUT KEEP RAIN OUT OF KCHS FOR NOW SINCE RAIN MAY NOT
REACH THAT TERMINAL UNTIL 09-10Z. THE RAIN COULD CERTAINLY BECOME
HEAVY AT TIMES LATE BUT ITS A BIT TOO FAR OUT TO GET THAT
SPECIFIC. WILL HAVE TO WATCH FOR THE POTENTIAL FOR LLWS THIS
EVENING WITH THE PASSAGE OF A COASTAL WARM FRONT. RIGHT NOW IT
APPEARS SURFACE WINDS WILL A BIT TOO HIGH FOR LLWS CRITERIA TO BE
MET. WE WILL CONTINUE TO MONITOR.
EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CIGS/VSBYS
ALONG WITH GUSTY WINDS WILL BE POSSIBLE TONIGHT THROUGH WEDNESDAY
NIGHT...AS A POTENT STORM SYSTEM MOVES THROUGH THE AREA AND BRINGS
PERIODS OF HEAVY RAIN AND POSSIBLY TSTMS. VFR CONDITIONS ARE THEN
EXPECTED THURSDAY THROUGH SATURDAY.
&&
.MARINE...
WINDS CONTINUE TO SURGE IN THE WAKE OF THE COLD FRONT EARLY THIS
MORNING. WILL MAINTAIN SMALL CRAFT ADVISORIES FOR THE CHARLESTON
COUNTY COASTAL WATERS AND THE GEORGIA OFFSHORE WATERS THROUGH 8
AM. NORTHEAST WINDS WILL PREVAIL ACROSS THE WATERS TODAY. THE
GRADIENT LOOKS TO REMAIN SOMEWHAT ENHANCED ACROSS THE GEORGIA
WATERS SO WINDS SHOULD REMAIN CLOSER TO 15-20 KT THERE FOR MUCH OF
THE DAY WITH 10-15 KT OVER THE SOUTH CAROLINA WATERS.
CONDITIONS WILL BEGIN TO CHANGE TONIGHT AS A COASTAL FRONT MOVES
INLAND AHEAD OF APPROACHING GULF LOW PRESSURE. WINDS ARE FORECAST
TO TO INCREASE ACROSS THE BOARD WITH THE ORIENTATION OF THE LOW-
LEVEL JET FAVORING THE GEORGIA OFFSHORE WATERS AND THE SOUTH
CAROLINA WATERS FOR THE HIGHEST WINDS. EITHER WAY...IT APPEARS
SEAS WILL BUILD TO SMALL CRAFT ADVISORY THRESHOLDS FOR ALL WATERS
BY SUNRISE WEDNESDAY...SO FLAGS WILL BE RAISED WITH THIS FORECAST
PACKAGE.
HAZARDOUS WINDS AND SEAS ARE EXPECTED TO PREVAIL ACROSS THE ENTIRE
MARINE AREA WEDNESDAY AS LOW PRESSURE MOVES WEST OF THE REGION.
STRONG LOW-LEVEL JETTING AND A TIGHTENING PRESSURE GRADIENT WILL
SUPPORT WINDS AS HIGH AS 25-30 KNOTS BY AFTERNOON. THE LATEST
MODEL BOUNDARY LAYER WINDS CONTINUE TO FAVOR FREQUENT GUSTS TO 35
KT GALES FOR THE SOUTH CAROLINA COASTAL WATERS AND THE GEORGIA
OFFSHORE WATERS BY EARLY AFTERNOON...SO A GALE WATCH WILL REMAIN
IN FORCE FOR THESE AREAS AND EXPANDED SOUTH TO INCLUDE THE WATERS
OFF BEAUFORT COUNTY. ALL OR PARTS OF THE GALE WATCH WILL LIKELY BE
UPGRADED TO A GALE WARNING THIS AFTERNOON OR EARLY WEDNESDAY
MORNING. SEAS WILL BUILD QUICKLY WITH THE STRENGTHENING OFFSHORE
FLOW...LIKELY REACHING AS HIGH AS 5-8 FT NEARSHORE WATERS AND 8-12
FT OFFSHORE WATERS.
WEDNESDAY NIGHT THROUGH SATURDAY...AN INTENSELY TIGHTENED
PRESSURE GRADIENT WILL REMAIN OVER THE MARINE ZONES WEDNESDAY
NIGHT...AS A POTENT LOW PRESSURE SYSTEM MOVES NORTHEAST ALONG THE
APPALACHIANS. THE COMBINATION OF VERY STRONG GRADIENT
WINDS...ALONG WITH IMPRESSIVE JETTING AT LOW AND MID LEVELS...WILL
CREATE VERY HAZARDOUS MARINE CONDITIONS ACROSS ALL WATERS INTO
THURSDAY MORNING. GALE WATCHES WILL CONTINUE FOR THE SOUTH
CAROLINA WATERS AND OFFSHORE GEORGIA ZONES...WHICH MAY NEED TO BE
EVENTUALLY UPGRADED TO GALE WARNINGS.
SOUTHERLY WINDS IN THE GALE WATCH ZONES COULD BE SUSTAINED 30 TO
35 KT...WITH HIGHER GUSTS. CHARLESTON HARBOR AND THE NEARSHORE
GEORGIA ZONES WILL LIKELY REACH AROUND 25 KT WEDNESDAY NIGHT. AS
THE FRONT PULLS EAST AWAY FROM THE COASTAL WATERS ON
THURSDAY...WINDS WILL VEER TO THE WEST AND DIMINISH.
HIGH PRESSURE WILL THEN GRADUALLY BUILD INTO THE REGION FROM THE
WEST THURSDAY AND FRIDAY. BOTH ECMWF AND GFS SUGGEST THE FORMATION
OF A COASTAL WAVE LATE FRIDAY COULD CAUSE NORTH WINDS TO SURGE
DEPENDING ON THE STRENGTH AND TRACK.
&&
.HYDROLOGY...
WIDESPREAD RAINFALL AMOUNTS OF 2-4 INCHES ARE EXPECTED WITH THIS
EVENT. FLASH FLOOD GUIDANCE VALUES LOOK HIGH ENOUGH TO PRECLUDE
WIDESPREAD FLASH FLOODING ACROSS MOST OF THE FORECAST AREA WITH
THE EXCEPTION OF THE COASTAL COUNTIES WHERE HIGH ASTRONOMICAL
TIDES MAY ENHANCED THE RISK FOR FRESH WATER FLOODING AROUND TIMES
OF HIGH TIDE. THE HIGH TIDE WEDNESDAY MORNING IS ESPECIALLY
WORRISOME. A FLASH FLOOD WATCH MAY EVENTUALLY BE CONSIDERED FOR
PARTS OF THE AREA OVER THE NEXT FEW FORECAST CYCLES.
PARTS OF THE LOWER SANTEE RIVER AND THE SAVANNAH RIVER REMAIN
ABOVE FLOOD STAGE. DEPENDING ON HOW MUCH RAINFALL FALLS UPSTREAM
OVER THE MIDLANDS...CSRA AND CENTRAL GEORGIA WATERSHEDS...SOME
FAIRLY SIGNIFICANT RISES MAY OCCUR OVER THE NEXT SEVERAL DAYS.
THIS MAY CAUSE SOME RIVERS TO RISE TO FLOOD STAGE AND PUSH
CURRENT RIVERS THAT ARE ALREADY IN FLOOD INTO HIGHER FLOOD
CATEGORIES.
&&
.TIDES/COASTAL FLOODING...
STRONG LOW PRESSURE WILL PASS WEST OF THE AREA WEDNESDAY.
CONSIDERING THAT HIGH PREDICTED ASTRONOMICAL TIDE LEVELS WILL BE
OCCURRING DURING THIS PERIOD...THE COMBINATION OF STRONG ONSHORE
FLOW AND HEAVY RAINFALL COULD RESULT IN TIDAL DEPARTURES
SIGNIFICANTLY HIGHER THAN PREDICTED VALUES. THE GFS EXTRATROPICAL
STORM SURGE GUIDANCE SHOWS TIDE LEVELS REACHING 7.8 FEET IN
CHARLESTON HARBOR AND 9.8 FEET AT FORT PULASKI DURING THE
WEDNESDAY MORNING HIGH TIDE. LOCAL COASTAL FLOODING DECISION TABLE
SUPPORTS RAISING A COASTAL FLOOD WATCH FOR ALL OF OUR COASTAL
ZONES ATTM GIVEN THE EXPECTED EXTRA INFLUENCES FROM HEAVY RAINS
AND A STRONG ONSHORE FLOW. ALTHOUGH TIDES MAY FALL SHORT OF THE
USUAL WARNING THRESHOLDS AT BOTH TIDE GAGES...OUR EXPERIENCE HAS
SHOWN THAT HEAVY RAINS AND STRONG ONSHORE WINDS DURING HIGH
ASTRONOMICAL TIDES TYPICALLY YIELD SIGNIFICANT COASTAL FLOODING
IMPACTS ALONG THE COAST. THESE IMPACTS ARE ENOUGH JUSTIFY THE
ISSUANCE OF A COASTAL FLOOD WATCH.
ASTRONOMICAL TIDES ARE EXPECTED TO REMAIN HIGH THURSDAY MORNING AS
WELL...AND COASTAL FLOOD ADVISORIES MAY AGAIN BE NECESSARY FOR
THE SOUTH CAROLINA AND GEORGIA COAST.
IN ADDITION TO HIGH TIDES AND COASTAL FLOODING...STRONG WINDS OVER
THE ATLANTIC COASTAL WATERS MAY RESULT IN A NEED FOR A HIGH SURF
ADVISORY WITH BREAKERS BUILDING TO BETWEEN 5 AND 7 FEET IN THE SURF
ZONE. THIS COULD ALSO RESULT IN MODERATE TO SIGNIFICANT BEACH
EROSION ALONG THE SOUTH CAROLINA AND GEORGIA COAST.
