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 MFL wrote it up.
A broad trough of low pressure across the eastern U.S. resulted in a moist and unstable environment over South Florida producing scattered afternoon thunderstorms.
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 Miami, FL wrote its last area forecast discussion before the first event at Aug 15, 12:43 PM EST, 12 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 143 PM EDT FRI AUG 15 2014 .AVIATION... FOR THE SHORT TERM...VERY ACTIVE CONVECTION WITH THUNDERSTORMS ACROSS THE EASTERN HALF OF THE PENINSULA WHICH WILL MOST LIKELY AFFECT TERMINALS KOPF...KFLL...KFXE AND KPBI IN THE NEXT HOUR OR TWO. ALTHOUGH IFR CONDITIONS NOT INCLUDED IN TEMPO GROUP FOR THOSE TERMINALS STARTING AT 18Z...BRIEF PERIODS OF IFR CONDITIONS WILL BE POSSIBLE AND WILL AMEND AS NECESSARY. OTHERWISE...THE MOST ACTIVE AREA OF CONVECTION THE REMAINDER OF THE AFTERNOON AND EARLY EVENING IS EXPECTED TO BE THE EASTERN HALF OF THE PENINSULA WITH ALL EAST COAST TERMINALS HAVING PERIODS OF SHOWERS/THUNDERSTORMS AND BRIEF PERIODS OF IFR CONDITIONS POSSIBLE INTO THE EARLY EVENING HOURS WITH OCCURRENCE OF THUNDERSTORMS. 60 && .PREV DISCUSSION... /ISSUED 1049 AM EDT FRI AUG 15 2014/ ...CORRECTION.... THE STORM MOTION IN THE AFD UPDATE WAS INADVERTENTLY STATED AS BEING TO THE NORTHWEST. IT SHOULD HAVE SAID TO THE NORTHEAST AND WAS CORRECTED BELOW. 60 UPDATE... CHANGES WERE MADE TO THE FORECAST FOR THIS MORNING AND TO THE AFTERNOON AND EVENING HOURS. REGIONAL RADARS INDICATE SHOWERS/THUNDERSTORMS ALONG THE SOUTHWEST GULF COASTAL ZONE AND MOVING EASTWARD AT A STEADY RATE. THE FORECAST WAS UPDATED TO INCREASE THE CHANCES OF SHOWERS/THUNDERSTORMS FOR GLADES/HENDRY COUNTIES THIS MORNING AND ALSO FOR THE NAPLES METRO AREAS AND ADJACENT GULF WATERS. FOR THIS AFTERNOON...THE LATEST GUIDANCE CONTINUES TO INDICATE THAT THE GREATEST COVERAGE OF SHOWERS/THUNDERSTORMS WILL BE ACROSS THE EASTERN HALF OF THE PENINSULA...INCLUDING THE ATLANTIC COAST METRO AREAS. THE FORECAST WAS UPDATED TO INCLUDE ALL ATLANTIC COAST METRO AREAS FOR NUMEROUS SHOWER/THUNDERSTORM ACTIVITY. THIS IS CONSISTENT WITH THE LATEST MESO-SCALE MODEL RESULTS AS WELL. IN ADDITION COVERAGE OF SHOWERS/THUNDERSTORMS WAS INCREASED FOR THE GULF AND ATLANTIC WATERS WITH THE MOST COVERAGE EXPECTED ACROSS THE ATLANTIC WATERS. WITH THE STORM MOTION TO THE NORTHEAST...THUNDERSTORMS WILL LIKELY EXIT OFF THE ATLANTIC COAST LATER THIS AFTERNOON AND AFFECT THE ADJACENT ATLANTIC WATERS. 60 PREV DISCUSSION... /ISSUED 807 AM EDT FRI AUG 15 2014/ AVIATION... SUFFICIENT MOISTURE AND INSTABILITY ALONG WITH SURFACE CONVERGENCENEAR THE COAST SHOULD LEAD TO NUMEROUS STORMS...WITH THE POTENTIAL FOR BRIEF IFR CONDS. WITH SW TO W WINDS...THE GULF COAST WILL BE FAVORED FOR DEVELOPMENT EARLY THIS MORNING...ALTHOUGH COVERAGE WAS SPARCE AT KAPF YESTERDAY. ONCE AGAIN...A BOUNDARY WILL SET UP PROBABLY JUST WEST OF A SW TO NE LINE FROM TMB TO OPF...WITH SHOWERS LATE THIS MORNING TO EARLY AFTERNOON. STORMS MAY AGAIN BE NUMEROUS ALONG THE BROWARD/PALM BEACH COUNTY COASTS LATE DAY. PREV DISCUSSION... /ISSUED 453 AM EDT FRI AUG 15 2014/ SHORT TERM... A BROAD TROUGH ACROSS THE EASTERN US WILL TURN THE FLOW MORE WEST TO SOUTHWEST ACROSS SOUTH FLORIDA TODAY. TYPICAL DIURNAL SHOWERS AND THUNDERSTORMS WILL DEVELOP ONCE HEATING DESTABILIZES THE LOW LEVELS ENOUGH. IT DOES APPEAR THAT THERE WILL BE HIGHER MOISTURE LEVELS FROM NORTH TO SOUTH, WITH PWATS OVER 2 IN. NORTH OF AROUND I75 THIS AFTERNOON. GFS INDICATES PWATS OF AROUND 1.8 IN THE MIAMI AREA. MODEL SOUNDING SHOWING THE NORMALIZED CAPE VALUES SOMEWHAT LOWER THAN YESTERDAY, INDICATING LOWER PARCEL ACCELERATIONS, BRINGING WEAKER CONVECTION. GFS SOUNDING SHOWS OVER 2000 JOULES/KG OF CAPE. 700-500MB LAPSE RATES LOOK TO BE BETWEEN 5.9 AND 6.5, DEPENDING ON THE MODEL. THIS SHOULD BE DECENT TO TRIGGER THE CONVECTION TIN THE LOW TO MID LEVELS. THERE IS ALMOST NO HELICITY, AND SHEAR IS UNDER 10 KTS AT SFC TO 1, 2, AND 3 KM. THE FZL WILL BE AROUND 15000 FT. THE 500MB TEMPS WILL BE AROUND -7.5 TO -8 C. SO WHAT DOES ALL THIS MEAN. AGAIN, PROBABLY TYPICAL THUNDERSTORMS THAT TEND TO PULSE, GIVEN THE WEAK PARCEL ACCELERATIONS. WITH THE HIGH MOISTURE CONTENT AND FZL AT 15000 FT, PROBABLY VERY LITTLE IN THE WAY OF HAIL, ALTHOUGH SOME LOCALIZED SMALL HAIL COULD POSSIBLY OCCUR. SLIGHT COLD POOL ALOFT MAY HELP WITH SOME GUSTY WINDS WITH ANY COLLAPSING STORMS TODAY. MODEL SOUNDINGS DO INDICATE THAT THERE IS AN AREA OF SOMEWHAT DRIER AIR EXPECTED BETWEEN 800 AND 700 MB. THIS COULD AIDE IN SOME OF THOSE GUSTY WINDS AS WELL. BUT, STILL THINKING JUST STRONG WINDS OF AROUND 45 KTS. THE NEXT QUESTION IS THE HEAVY RAIN POTENTIAL. WITH THE HIGHER PWATS THERE WILL BE PLENTY OF MOISTURE. LOOKING AT THE BUFKIT MBE VELOCITIES, STORM MOTION WILL BE PRETTY SLOW, WITH VALUES OF 3 TO 5 KTS. GIVEN THIS, IT WILL BE POSSIBLE TO SEE TYPICAL URBAN STREET FLOODING ACROSS SOUTH FLORIDA, WITH CHANCES INCREASING FROM SOUTH TO NORTH, ALONG WITH THE HIGHER PWATS. AFTER TODAY, UPPER LEVEL HIGH PRESSURE WILL BEGIN TO BUILD OVER THE FLORIDA PENINSULA. AT THE SFC, THE HIGH TO THE EAST BEGINS TO STRENGTHEN. THIS WILL MAINLY BRING BACK THE SOUTHERLY SFC FLOW AND WEAK STEERING FLOW ALOFT, GENERALLY UNDER 10 KTS. THE SEA BREEZES SHOULD BE ABLE TO DEVELOP ONCE AGAIN, AND BE THE MAIN TRIGGERING MECHANISM FOR CONVECTION ON SATURDAY AND SUNDAY. HOWEVER, BY SUNDAY, CONVECTION MAY BE LIMITED BY A DRIER AIR MASS. THE GFS IS BRINGING PWATS DOWN TO AROUND 1.5 TO 1.6 INCHES ACROSS ALMOST THE ENTIRE AREA. THIS WILL HELP TO INHIBIT MUCH OF THE CONVECTION, EXCEPT UP BY THE LAKE REGION, WHERE PWATS MAY BE SLIGHTLY HIGHER. LONG TERM... IN THE EXTENDED, RIDGING CONTINUES. THE DRIER AIR WILL ALSO HANG AROUND THROUGH AT LEAST MONDAY, HELPING TO LIMIT CONVECTION SOMEWHAT. BY TUESDAY AFTERNOON, THE GFS IS SHOWING PWATS OF OVER 2 INCHES TRYING TO MAKE A COME BACK. ALSO, THE LOW LEVEL FLOW LOOKS TO BE MORE EASTERLY. THIS WOULD INDICATE CONVECTION BEING ENHANCED AND SHIFTING TOWARDS THE GULF COAST. THIS LOOKS TO REMAIN PERSISTENT THROUGH THE REMAINDER OF THE FORECAST PACKAGE. SO, EXPECT AFTERNOON SHOWERS AND THUNDERSTORMS EACH DAY, MAINLY AFFECTING THE INTERIOR AND GULF COASTS. AVIATION... LIGHT AND VARIABLE WINDS ARE EXPECTED TO GIVE WAY TO A LIGHT SOUTH-SOUTHWEST FLOW ACROSS THE AREA. AS THE EAST COAST SEA BREEZE DEVELOPS LATER THIS AFTERNOON...COASTAL CONVERGENCE SHOULD GENERATE SHRAS/TSRAS ACROSS THE INTERIOR AND EAST COASTAL AREAS. THEREFORE KEPT VCTS IN AT ALL SITES AFTER 17Z WITH LIGHT WINDS RETURNING AFTER 00Z. MARINE... HIGH PRESSURE WILL KEEP WINDS GENERALLY BELOW 12 KTS FOR THE FORESEEABLE FUTURE. THERE WILL BE ON AND OFF AGAIN CONVECTION, ALTHOUGH THERE MAY BE LESS COVERAGE AND INTENSITY SUNDAY AND MONDAY AS HIGH PRESSURE AND SLIGHTLY DRIER ARE ARE IN PLACE. && .PRELIMINARY POINT TEMPS/POPS...
