The episode as NWS MLB wrote it up.
A very moist atmosphere coupled with a series of upper level disturbances resulted in several persistent rainbands. Significant urban and small stream flooding affected portions of Melbourne/Palm Bay and Lake Mary/Winter Park. Flash flooding resulted in rapid water accumulation in New Smyrna Beach and from Holly Hill to Daytona Beach to Port Orange, where numerous roadways became impassible and over 100 homes sustained damage from the rising flood waters. Rainfall totals during the 24-hour period of greatest impact reached 6-12 inches. Flood damage estimates within Volusia County was 3.65 million dollars. No injuries were reported.

NWS Melbourne, FL wrote its last area forecast discussion before the first event at Sep 23, 7:54 AM EST, 6 hours 6 minutes earlier.
EAST CENTRAL FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 854 AM EDT TUE SEP 23 2014 .DISCUSSION... ...WET LATE SEPTEMBER WEATHER PATTERN CONTINUES... REGIONAL CONDITIONS SHOW VERY FAVORABLE SETUP FOR DEVELOPMENT OF DEEP CONVECTION TODAY. THE LTST SOUNDING FROM XMR/TBW SHOW MOISTURE DEPTH HAS INCREASED OVER PAST 24H WITH NR TWO INCHES PWAT IN PLACE. SOME MID-LEVEL COOLING ON THE XMR DATA IS ALSO EVIDENT. A VEERING PROFILE FROM 0-1KM ALONG WITH SOME SPEED SHEAR IN THE 0-3KM LAYER WILL PROMOTE POSSIBILITY OF A FEW ROTATING UPDRAFTS IN DEVELOPING CELLS. MARGINAL HEATING SHOULD BE OVERCOME BY THE SLIGHTLY HIGHER ENVIRONMENTAL LAPSE RATE. CURRENT 70 PCT COVERAGE IS REASONABLE WITH SCT THUNDER AND POSSIBILITY OF LOCALLY HEAVY RAIN. HAVE RAISED EXPECTED QPF AMOUNTS FOR THE AFTERNOON HOURS TO AROUND 0.50 INCHES. BRINGING BASIN QPF FROM MORNING THROUGH 00Z TO AROUND 0.75 TO AN INCH . WL CONTINUE TO MONITOR SOME SENSITIVE AREAS FOR NUISANCE FLOODING POTENTIAL. PREV DISC...THE OLD FRONTAL BOUNDARY ACROSS THE NORTHERN PENINSULA HAS PRETTY MUCH MERGED WITH THE FRONT TO THE NORTH...WHICH HAS NOW SAGGED SWD INTO THE SAME GENERAL REGION. LIGHT SE TO SRLY FLOW IS STILL IN PLACE ALONG THE SWRN PERIPHERY OF THE ATLC HIGH PRES RIDGE WELL TO THE NE OF FL. A MID TO UPPER LEVEL TROUGH EXTENDS FROM NEAR THE SERN SEABOARD...ACROSS NORTH FL AND INTO THE NERN GOMEX. LOCAL RADAR MOSAIC PRECIP FREE ACROSS ECFL...WITH STRONG CONVECTIVE BANDS WELL TO THE NORTH...SW AND SE...SHOWING A WEAKENING TREND AS OF LATE. TODAY/TONIGHT...NEXT 24 HOURS SHOWS LITTLE CHANGE AT THE SURFACE OR ALOFT AS BOTH THE MID/UPPER TROUGH AND SURFACE FRONTAL BOUNDARY STAY IN PLACE. MODEL GUIDANCE HINTS AT A WEAK SURFACE WAVE FORMING OVER NORTH FL ALONG THE FRONT LATER TODAY AND SLIDING NE UP THE ERN SEABOARD BY TONIGHT. IN ANY EVENT...VERY HIGH MEAN PWATS SPELL ANOTHER AFTERNOON OF WIDESPREAD COVERAGE OF SHOWER AND STORMS WITH LOCALLY HEAVY RAINFALL CREATING SOME URBAN TYPE FLOODING PROBLEMS IN SOME AREAS. HAVE PAINTED A 70 FOR THE ENTIRE CWA. CLOUDS/PRECIP WILL LIKELY HOLD MAX TEMPS DOWN ABOUT 1-2F BELOW CLIMO...BUT STILL M-U80S FOR ALL AREAS. SCATTERED EVENING SHOWERS AND SOME STORMS FOR THIS EVENING GRADUALLY TAPERING OFF BY MIDNIGHT OR A LITTLE BEFORE. && .AVIATION...VFR CONDS DURING THE MORNING WITH DEVELOPMENT OF LOWER BASES AND LIKELIHOOD OF CIGS NR FL 030-040FT AFT 15Z.

CONDS UNLIKELY TO SHOW MUCH CHANGE OVER THE NEXT H24 GIVEN THE STAGNANT PATTERN SFC AND ALOFT. MAIN MARINE CONCERN WILL REMAIN THE HIGH COVERAGE OF OFFSHORE-MOVING SHOWERS AND STORMS...WHICH WILL PRODUCE LOCALLY HIGHER WINDS/SEAS. && .HYDROLOGY...AHPS DATA SHOWS THE LATEST STAGE HEIGHT AT SHINGLE CREEK AT CAMPBELL 57.24FT WITH A CONTINUED SLOW FALL (ACTION STAGE 58.00FT). THE ST JOHNS RIVER AT ASTOR WAS 2.34FT AND REMAINING STEADY (ACTION STAGE 2.50FT). WILL CONTINUE TO MONITOR THESE SITES CLOSELY GIVEN THE FORECAST OF HIGH RAIN CHANCES AND GENEROUS AREAL-AVERAGED QPF (0.60 TO 0.70 THROUGH THIS EVENING AND ABOUT 0.25 TO 0.50" EACH OF THE NEXT SEVERAL 24-HOUR PERIODS). THERE REMAINS THE POSSIBILITY THAT THE LOCALLY HIGHER AMOUNTS THAT INVARIABLY FALL IN STRONGER CONVECTION COULD AFFECT THESE LOCATIONS WITH 2-3+ RAINFALL TOTALS. && .MLB WATCHES/WARNINGS/ADVISORIES...

A WEAK FRONTAL BOUNDARY STRETCHING ACROSS NORTH FLORIDA WILL REMAIN STATIONARY TODAY...AS WILL A WEAK UPPER LEVEL TROUGH OVER THE STATE. VERY DEEP MOISTURE REMAINING IN PLACE COUPLED WITH DAYTIME HEATING AND LOCAL SEA AND LAKE BREEZE BOUNDARIES WILL LEAD TO NUMEROUS SHOWERS AND STORMS ACROSS THE REGION TODAY...MAINLY DURING THE AFTERNOON AND EARLY EVENING. STORM MOTION WILL BE NORTH TO NORTHEAST UP TO 10 TO 15 MPH. A FEW STRONGER STORMS COULD PRODUCE FREQUENT CLOUD TO GROUND LIGHTNING...TORRENTIAL DOWNPOURS...AND WIND GUSTS TO 40 TO 50 MPH. MOVE INDOORS IF SKIES LOOK THREATENING...OR IF YOU HEAR THUNDER IN THE DISTANCE. .FLOOD IMPACT... RAINFALL AMOUNTS OF 1 TO 3 INCHES WILL BE POSSIBLE IN A 60 TO 90 MINUTE PERIOD FROM SLOW MOVING STORMS TODAY. THIS WOULD RESULT IN TEMPORARY FLOODING OF STREETS...INTERSECTIONS...AND OTHER POORLY DRAINED LOW LYING AREAS. THIS IS ESPECIALLY THE CASE IN AREAS WHICH RECEIVED HEAVY RAINS OVER THE LAST FEW DAYS. .MARINE THUNDERSTORM GUST IMPACT... STORMS WILL ALSO BE CAPABLE OF PRODUCING LOCAL WIND GUSTS TO AROUND 35 KNOTS OVER INLAND LAKES AS WELL AS THE INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS. BOATERS SHOULD BE ALERT FOR STORMS APPROACHING FROM THE SOUTH TO SOUTHWEST TODAY...AND SEEK SAFE HARBOR IF SKIES LOOK THREATENING. .WATERSPOUT IMPACT... THE COMBINATION OF VERY DEEP MOISTURE AND LIGHT ENVIRONMENTAL WINDS COULD LEAD TO THE DEVELOPMENT OF FUNNEL CLOUDS OR WATERSPOUTS NEAR OR OVER THE INTRACOASTAL WATERWAY...THE NEAR SHORE ATLANTIC...AND THE NORTH SHORE OF LAKE OKEECHOBEE. .RIVER FLOOD IMPACT... WATER LEVELS CONTINUE TO SLOWLY RECEDE ALONG SHINGLE CREEK NEAR CAMPBELL AND ON THE SAINT JOHNS RIVER AT ASTOR. HOWEVER...RAIN CHANCES REMAIN HIGH...WITH THE POTENTIAL FOR LOCALIZED AMOUNTS OF 1 TO 3 INCHES OR A LITTLE HIGHER. SHOULD THESE LOCALLY HEAVY RAINFALL AMOUNTS OCCUR IN THESE LOCATIONS...IT WOULD CAUSE WATER LEVELS TO RISE ONCE AGAIN. LISTEN FOR ANY STATEMENTS OR UPDATES FROM THE NATIONAL WEATHER SERVICE...OR COUNTY OFFICIALS...IF YOU LIVE NEAR EITHER OF THESE LOCATIONS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY. ABOVE NORMAL RAINFALL CHANCES WILL OCCUR THROUGH THIS WEEKEND... AND THE THREAT FOR LOCALLY HEAVY RAINFALL WILL CONTINUE. LOCALIZED TEMPORARY FLOODING OF ROADS IN SOME AREAS DURING MOST OF THE UPCOMING AFTERNOON AND EARLY EVENING PERIODS. WHILE RAIN CHANCES REMAIN HIGH FROM WEDNESDAY THROUGH FRIDAY...FRESHENING ONSHORE FLOW MAY DECREASE THE COVERAGE AND INTENSITY OF STORMS SLIGHTLY. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY. HOWEVER...SPOTTERS ARE ASKED ONCE AGAIN TO PLEASE REPORT ANY RAINFALL AMOUNTS OF TWO INCHES OR GREATER TO THE NATIONAL WEATHER SERVICE OFFICE IN MELBOURNE. CRISTALDI/WEITLICH
