What happened

The episode as NWS MLB wrote it up.

A stationary upper-level disturbance, strong onshore flow, and a weak frontal boundary produced persistent heavy rainfall and squalls across a large portion of east central Florida on October 7-8.

A strong gale then formed over the Bahamas on October 9 and moved northwest and onto the Brevard and Volusia County coast late in the evening. As the gale approached the coast, heavy convective bands and storm-force winds developed west of the center of circulation. While not a tropical storm, the system briefly possessed some tropical/sub-tropical characteristics. Winds gusted between 50 and 80 mph along much of the coast. Additional heavy rains added to the totals of the previous several days. The combination of the saturated grounds and high wind gusts caused numerous, mostly small trees, to be toppled, mainly across coastal Brevard and Volusia Counties. Tree branches were also downed and many power outages occurred.

A large portion of east central Florida received 72-hour storm total rainfall greater than 5 inches, with parts of Brevard, Indian River, and Osceola Counties reaching 10 to nearly 17 inches of rain. Unseasonably dry soil conditions prior to the event minimized significant flooding, however, minor flooding, and high levels of standing water were experienced within several counties.

What forecasters said that day

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 Melbourne, FL wrote its last area forecast discussion before the first event at Oct 7, 9:05 PM EST, 4 hours 55 minutes earlier.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT.

.THUNDERSTORM IMPACT...
LINES OF SHOWERS WITH EMBEDDED THUNDERSTORMS OVER THE COASTAL
WATERS WILL MOVE TO THE WEST AT 20 TO 25 MPH. AS THESE SHOWERS AND
STORMS COME ASHORE THEY WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY
RAIN WITH WIND GUSTS TO 40 MPH AND LIGHTNING STRIKES AT THE COAST
AND INLAND TO THE INTERSTATE 95 CORRIDOR BEFORE STARTING TO DIMINISH
IN INTENSITY.

.FLOOD IMPACT...
PERIODIC HEAVY RAIN WILL OCCUR THROUGH TONIGHT...ESPECIALLY ALONG
THE COAST. LOCALLY HEAVY RAIN ALREADY HAS OCCURRED IN THE MARTIN
AND SAINT LUCIE COUNTIES...AND ACROSS NORTHERN VOLUSIA COUNTY. THE
ADDITIONAL RAIN WILL CAUSE LOW LYING AND POOR DRAINAGE AREAS TO
FLOOD THAT WILL RESULT IN HAZARDOUS DRIVING CONDITIONS. A FLOOD
WATCH IS IN EFFECT THROUGH LATE SUNDAY NIGHT FOR COASTAL
VOLUSIA...INDIAN RIVER...INLAND VOLUSIA...MARTIN...NORTHERN
BREVARD...OKEECHOBEE...ORANGE... OSCEOLA...SEMINOLE...SOUTHERN
BREVARD AND ST. LUCIE COUNTIES.

.COASTAL FLOOD IMPACT...
STEADY EAST NORTHEAST WINDS WILL GENERATE ROUGH SURF ALONG AREA
BEACHES THROUGH TONIGHT. THESE WAVES WILL BE CAPABLE OF PRODUCING
MINOR BEACH EROSION DURING THE NEXT COUPLE OF HIGH TIDE CYCLES. A
HIGH SURF ADVISORY WILL BEGIN AT 4 PM THIS AFTERNOON.

.MARINE THUNDERSTORM GUST IMPACT...
SHOWERS AND STORMS WILL PRODUCE BRIEF WIND GUSTS OVER 34 KNOTS.
GIVEN THE ROUGH CONDITIONS ALREADY IN PLACE OVER THE OPEN ATLANTIC
AND THE INTRACOASTAL WATERWAY...BOATERS ARE URGED TO REMAIN IN
PORT OR AT DOCK.

.WIND AND SEA IMPACT...
A FRESH TO STRONG EAST NORTHEAST BREEZE WILL PREVAIL ACROSS THE
LOCAL ATLANTIC...GENERATING SEAS BETWEEN TO 7 FEET A FEW MILES OFF
THE COAST TO 12 FEET WELL OFFSHORE IN THE GULF STREAM. A SMALL CRAFT
ADVISORY REMAINS IN EFFECT THROUGH MONDAY AFTERNOON.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
UNSETTLED WEATHER WILL CONTINUE THROUGH THE WEEKEND AS A LOW
PRESSURE AREA DEVELOPS NEAR SOUTH FLORIDA. COMBINED WITH A SURFACE
BOUNDARY DROPPING TOWARDS THE PENINSULA...LOW PRESSURE ALOFT...AND
INCREASING MOISTURE...A SIGNIFICANT RAIN EVENT IS EXPECTED...
ESPECIALLY ALONG THE COAST. BREEZY TO WINDY CONDITIONS WILL
CONTINUE INTO THE WEEKEND DUE TO A TIGHTENING PRESSURE GRADIENT
ACROSS THE AREA. STAY TUNED FOR SPECIFIC HAZARDS RELATED TO LOW
PRESSURE DEVELOPMENT AND OR THE THREAT OF HEAVY RAINS.

SEAS WILL INCREASE THROUGH THE WEEKEND AND WILL REMAIN HAZARDOUS
INTO EARLY NEXT WEEK. THIS WILL RESULT IN ROUGH SURF AND POSSIBLE
BEACH EROSION AT HIGH TIDE. WINDS OVER THE COASTAL WATERS ALSO
WILL REMAIN ELEVATED INTO EARLY NEXT WEEK WITH OCCASIONAL GUSTS TO
GALE FORCE POSSIBLE THROUGH THE WEEKEND. THE RIP CURRENT THREAT
AT EAST CENTRAL FLORIDA BEACHES WILL BE MODERATE TO HIGH.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
