Onshore winds along with 3 to 4 foot swells every 8 to 9 seconds, resulted in an increased risk for rip currents at the Georgia beaches.
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.
Onshore winds along with 3 to 4 foot swells every 8 to 9 seconds, resulted in an increased risk for rip currents at the Georgia beaches.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 17, 9:16 AM EST, 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 1016 AM EDT SAT JUL 17 2010 .SYNOPSIS... THROUGH NEXT WEEK...ATLC HIGH PRES WILL EXTEND ACROSS THE AREA... AND A TROUGH OF LOW PRES WILL PERSIST INLAND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... ONGOING FORECASTS REMAIN ON TRACK AND REQUIRED ONLY MINOR ADJUSTMENTS SATURDAY MORNING. THE MEAN SURFACE-500 MB RIDGE WILL EXTEND FROM THE ATLANTIC ACROSS THE CWFA THROUGH THIS AFTERNOON. THE RESULTING LARGE SCALE SUBSIDENCE SHOULD AGAIN LIMIT CONVECTION COVERAGE. HOWEVER... SEVERAL FEATURES COULD SUPPORT GREATER DIURNAL THUNDERSTORM COVERAGE. AT THE UPPER LEVELS...CYCLONIC CIRCULATION ASSOCIATED WITH A TUTT LOW CENTERED OVER SOUTH FL WAS EDGING TOWARD THE FORECAST AREA FROM THE S/SE...PRODUCING SOME WEAK 300 MB DIFFLUENCE AS DEPICTED BY AREA 12Z UA OBSERVATIONS. ALSO...A SW-NE MID LEVEL SHEAR AXIS WAS EVIDENT ON THE 500 MB ANALYSIS/WATER VAPOR IMAGERY. THESE FEATURES WILL PROVIDE WEAK MID/UPPER LEVEL SUPPORT AS THE SEA BREEZE PROGRESSES STEADILY INLAND DURING THE AFTERNOON AND EVENING PRODUCING ISOLATED/SCATTERED THUNDERSTORMS...AND AS AN ADDITIONAL THUNDERSTORMS FIRE NEAR AN INLAND SURFACE TROUGH IN THE LEE OF THE APPALACHIANS. MAXIMIZED AFTERNOON POPS AT 30-40 PERCENT OVER THE WESTERN HALF OF THE REGION WHERE THE BEST THETA-E WILL BE LOCATED. LOCALLY HIGHER POPS COULD EVENTUALLY BE REQUIRED AS OUTFLOW BOUNDARIES DEVELOP AND DRIVE NEW CONVECTION. WHILE MID LEVEL LAPSE RATES REMAIN POOR...LESS THAN 6 C/KM... LOW LEVEL LAPSE RATES ARE AS MUCH AS 7-8C...MLCAPES 2500-3500 J/KG PER MODIFIED 12Z SOUNDINGS DURING PEAK HEATING...INVERTED V SOUNDING PROFILES...DCAPES EXCEEDING 1000 J/KG AND WINDEX VALUES OVER 60 KT SUGGEST THAT ISOLATED PULSE T-STORMS COULD BECOME BRIEFLY LOCALLY STRONG/SEVERE WITH DAMAGING DOWNBURST/MICROBURST WINDS ESPECIALLY WHERE BOUNDARY INTERACTIONS OCCUR. LOCALLY HEAVY RAIN COULD ALSO OCCUR GIVEN PWATS 1.75-2 INCHES/WEAK STEERING FLOW. TEMPS WILL BE SIMILAR TO YESTERDAY WITH LITTLE CHANGE IN 850 MB TEMPS/1000-850 MB THICKNESS. EXPECT HIGHS IN THE LOWER/MIDDLE 90S AWAY FROM THE BEACHES...WHERE SEA BREEZE CIRCULATION WILL HOLD TEMPS IN THE MID AND UPPER 80S. WITH DEW POINTS GENERALLY BETWEEN 70 AND 75 DEGREES...THE RESULTING HEAT INDICES AS HIGH AS 103-105 DEGREES. && .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/... TONIGHT...THE BULK OF THE CONVECTION IS DIURNALLY DRIVEN...SO LOOK FOR MOST ACTIVITY TO END BY MIDNIGHT. THERE IS HOWEVER THE RISK FOR ISOLATED ACTIVITY OVER NORTHERN AREAS OVERNIGHT WITH LINGERING BOUNDARIES FROM NEARBY TROUGH BOTH SURFACE AND ALOFT. ANOTHER WARM AND MUGGY NIGHT WITH MIN TEMPS NO LOWER THAN THE LOWER AND MIDDLE 70S INLAND...TO THE UPPER 70S OR NEAR 80 AT THE COAST. SUNDAY...THE BERMUDA HIGH PERSISTS ACROSS THE AREA WITH THE AXIS OF THE SURFACE TO 500 MB RIDGE CENTERED EAST-WEST ACROSS SE GA. WHILE THE SEA BREEZE AND LEE SIDE TROUGH WILL AGAIN BE THE MAIN TRIGGERS FOR CONVECTION...A SHORT WAVE TROUGH MOVES IN FROM THE NW DURING THE AFTERNOON AND HELPS TO ENHANCE COVERAGE OF SHOWERS/T-STORMS THE SECOND HALF OF THE DAY. COVERAGE OF CONVECTION WILL GENERALLY BE 20-30 PERCENT...EXCEPT FOR 40 POPS ALONG THE NW TIER IN CLOSER PROXIMITY TO THE PVA ALOFT WITH THE SHORT WAVE. DCAPES OF 1200 J/KG ARE SUPPORTIVE OF ISOLATED STRONG/DAMAGING WINDS WHERE BOUNDARY COLLISIONS ENHANCE THE STRENGTH OF UPDRAFTS. PLUS THERE IS STILL THE RISK OF LOCALLY HEAVY RAINS WITH PWATS NEAR 2 INCHES AND LIMITED STORM MOTION. LITTLE CHANGE IN TEMPS /LOWER-MID 90S AWAY FROM THE SHORELINE/...DEW POINTS /70-75/ AND HEAT INDICES /100-105 DEGREES OR JUST BELOW HEAT ADVISORY CRITERIA/. MONDAY...THE SURFACE AND LOW TO MID LEVEL RIDGE WILL AGAIN PREVAIL FROM THE ATLANTIC...WHILE THE PERSISTENT SURFACE TROUGH REMAINS TO THE LEE OF THE APPALACHIANS. WITH NVA IN WAKE OF THE SHORT WAVE FROM SUNDAY AND LESS AVAILABLE MOISTURE AS PWATS FALL TO 1.5-1.75 INCHES...WE HAVE DROPPED POPS TO 20 PERCENT AREA WIDE...WITH THE SEA BREEZE BOUNDARY THE MAIN FOCUS FOR CONVECTION. TEMPS AND THEIR ASSOCIATED HEAT INDICES WILL CHANGE LITTLE FROM RECENT DAYS. TUESDAY...LITTLE CHANGE IN THE SURFACE PRESSURE PATTERN WITH A CONTINUATION OF ATLANTIC RIDGING ACROSS THE AREA...AND A TROUGH FAR INLAND. BUT ALOFT WE DO START TO SEE THE MID LEVEL ANTICYCLONE STRENGTHENING WITH 500 MB HEIGHTS CLIMBING TO 5940/5950 METERS ATOP THE LOCAL AREA. THE LARGE SCALE SUBSIDENCE WILL LIMIT COVERAGE OF CONVECTION TO NO MORE THAN 20-30 PERCENT. TEMPS WILL BE ABOVE CLIMATOLOGICAL NORMALS IN THE LOWER-MID 90S INLAND...AND ASSOCIATED HEAT INDICES WILL BE CLOSE TO 105 DEGREES. && .LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/... A STRONG MID LEVEL RIDGE REMAINS IN PLACE OVER THE SE THROUGH THURSDAY...BEFORE SLOWLY RETROGRADING FRIDAY AS A TUTT LOW MOVES INTO THE SW ATLANTIC FROM THE EAST-SE. OUR 500 MB HEIGHTS ARE AS HIGH AS 5950/5960 METERS WHICH SUGGESTS THAT CONVECTION WILL BE HARD PRESSED IN DEVELOPING. HOWEVER...WITH CONSIDERABLE LOW LEVEL MOISTURE AND FORCING FROM THE SEA BREEZE AND NEARBY PIEDMONT TROUGH...WE WILL CARRY 20-30 POPS IN THE EXTENDED PERIODS OF THE FORECAST. LOW LEVEL THICKNESS FORECAST INDICATES THAT MAX TEMPS WILL REACH AT LEAST THE MID 90S INLAND...WHICH WILL PUSH HEAT INDICES OVER 105 DEGREES. THUS HEAT ADVISORIES ARE LIKELY DURING THE MIDDLE AND LATTER PARTS OF NEXT WEEK. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... SUBSIDENCE CAP IN PLACE ACROSS THE TERMINALS THIS MORNING WILL BREAK THIS AFTERNOON AS SEA BREEZE BOUNDARY PUSHES THROUGH...RESULTING IN THE DEVELOPMENT OF FEW-SCT CUMULUS CLOUDS AROUND 3-4KT. WE HAVE ADDED CB CLOUDS TO KSAV GIVEN THAT THEY HAVE BETTER LOW LEVEL MOISTURE THAN AT KCHS...THE KSAV TERMINAL IS IN CLOSER PROXIMITY TO A WEAK SHORT WAVE TO THE SOUTH...AND THE SEA BREEZE BOUNDARY PUSHES THROUGH KSAV DURING THE TIME OF MAX HEATING. THE BULK OF THE CONVECTION HOWEVER WILL REMAIN WEST AND NW OF THE TERMINALS THIS AFTERNOON AND EVENING...BEFORE ENDING EARLY TONIGHT. BOUNDARIES MOVING IN FROM THE NW TONIGHT MAY IMPACT KCHS WITH A SMALL RISK OF SHRA/TSRA AND MARGINAL MVFR CONDITIONS...BUT CONFIDENCE/PROBABILITIES ARE MUCH TOO LOW TO INCLUDE WITH THE 12Z TAFS. SOUTH AND SW WINDS WILL GENERALLY HOLD AT 10 KT OR LESS...EXCEPT FOR 10-15 KT THIS AFTERNOON AT KCHS AS SOME PINCHING OF THE PRESSURE GRADIENT DEVELOPS BETWEEN THE RESULTANT SEA BREEZE AND THE PIEDMONT TROUGH. EXTENDED AVIATION OUTLOOK...OUTSIDE OF A BRIEF PERIOD OF MARGINAL MVFR WEATHER IN ISOLATED AFTERNOON/EVENING CONVECTION...CONDITIONS WILL BE MAINLY VFR THROUGH WEDNESDAY. && .MARINE... ATLANTIC HIGH PRESSURE WILL MAINTAIN ITS WESTERN EXTENT OVER THE CHS MARINE AREA TODAY AND CONTINUE AS THE PREVAILING FEATURE THROUGH TONIGHT. WINDS/SEAS WILL REMAIN ELEVATED DUE TO ONSHORE WINDS ENHANCED BY THE SEABREEZE THROUGH THE EVENING AND PER NOCTURNAL TRENDS ON PERIPHERY OF THE HIGH PRESSURE TONIGHT. S S/W WINDS WILL AVERAGE 15-20 KNOTS AND SEAS WILL REMAIN CAPPED AT 2-4 FT WITH NEARSHORE WATERS AND 4-5 FT BEYOND 20 NM. SCA CONDITIONS ARE NOT EXPECTED. THE ATLANTIC HIGH PRESSURE AREA WILL REMAIN THE DOMINANT WEATHER FEATURE FOR THE CHS COASTAL WATERS THROUGH THE FIRST HALF OF NEXT WEEK. THIS PATTERN WILL MAINTAIN A TYPICAL SOUTHERLY FLOW...WITH WINDS MORE SOUTHWEST IN THE MORNINGS AND SOUTH-SOUTHEAST IN THE AFTERNOONS DUE TO THE SEABREEZE CIRCULATIONS. SPEEDS WILL REMAIN CAPPED AT 15 KT DESPITE THE SEABREEZE AND NOCTURNAL SURGES EXPECTED EVERY DAY THROUGH THE START OF NEXT WEEK. SEAS WILL REMAIN NO HIGHER THAN 4-5 FT...A COMBINATION OF 2 TO 4 FT SOUTHERLY WIND WAVES AND SOUTHEAST SWELLS OF 2 TO 3 FT EVERY 8 OR 9 SECONDS AS THE RIDGE PERSISTS. CONDITIONS LOOK TO REMAIN BELOW SCA THRESHOLDS. RIP CURRENTS...MODERATE ONSHORE WINDS AT THE BEACHES TODAY ALONG WITH 3 TO OCCASIONAL 4 FOOT SWELLS EVERY 8 OR 9 SECONDS ARE SUPPORTIVE OF A MODERATE RISK OF RIP CURRENTS. REMEMBER THAT DURING A MODERATE RISK ONLY EXPERIENCED SURF SWIMMERS SHOULD ENTER THE WATER. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
