The radar

The Melbourne radar (KMLB), 60 km from the middle of the area, began a volume at 21:12 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Cape Canaveral, FL (KXMR), launched 12:00Z, 9.2 hours before the alert went out and 98 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

...THUNDERSTORM IMPACT...
TROPICAL MOISTURE WILL CONTINUE TO INCREASE OVER THE AREA THROUGH
TONIGHT SOUTH OF A STALLED FRONTAL BOUNDARY OVER NORTH CENTRAL
FLORIDA. ABOVE NORMAL RAIN CHANCES ARE EXPECTED...WITH SHOWERS
INCREASING IN COVERAGE AND BECOMING SCATTERED TO NUMEROUS INTO THIS
AFTERNOON. INCREASING MID LEVEL CLOUD COVER OVER OKEECHOBEE COUNTY
AND THE TREASURE COAST SHOULD LIMIT STORM ACTIVITY LATER TODAY.
HOWEVER...WE MAY SEE MORE SCATTERED STORMS DEVELOP FROM THE ORLANDO
AREA NORTHWARD NEAR THE STALLED FRONT AND WHERE GREATER DAYTIME
HEATING IS EXPECTED.

THE MAIN THREATS FROM ANY STRONGER STORMS THAT DEVELOP WILL BE
FREQUENT CLOUD TO GROUND LIGHTNING...GUSTY WINDS UP TO 35 TO 40
MPH AND HEAVY DOWNPOURS. STORM MOTION TODAY WILL BE TOWARD THE
NORTH TO NORTHEAST AROUND 20 MPH.

...FLOOD IMPACT...
SHOWERS WILL INCREASE OVER THE AREA INTO TONIGHT WITH THE HIGHEST
COVERAGE EXPECTED ALONG THE TREASURE COAST. LOCALLY HEAVY
RAINFALL UP TO 1 TO 3 INCHES WILL BE POSSIBLE WHERE ANY PERSISTENT
SHOWER BAND ACTIVITY OCCURS. A FLOOD WATCH WILL BE IN EFFECT FOR
TONIGHT FOR INDIAN RIVER...SAINT LUCIE AND MARTIN COUNTIES.

...MARINE THUNDERSTORM GUST IMPACT...
NUMEROUS STORMS WILL BE ABLE TO DEVELOP ACROSS THE COASTAL WATERS
TODAY AND GENERALLY MOVE TO THE NORTH TO NORTHEAST AROUND 20 MPH. A
FEW STORMS WILL ALSO PUSH OFFSHORE WITH THE POTENTIAL TO PRODUCE
WIND GUSTS UP TO 35 TO 40 MPH.

...WATERSPOUT IMPACT...
SHOWER BANDS ARE EXPECTED TO INCREASE OVER THE TREASURE COAST
INTO TONIGHT AND WILL HAVE THE POTENTIAL TO PRODUCE BRIEF FUNNEL
CLOUDS AND POSSIBLY A WATERSPOUT ALONG THE NEARSHORE AND
INTRACOASTAL WATERS.

...WIND AND SEA IMPACT...
SOUTHEASTERLY WINDS WILL INCREASE AND BEGIN TO DETERIORATE MARINE
CONDITIONS OVER THE COASTAL WATERS LATER TONIGHT. WINDS OFFSHORE
WILL REACH 15 TO 20 KNOTS...BUILDING SEAS UP TO 4 TO 6 FEET.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
A TROPICAL DEPRESSION OVER THE NORTHWEST CARIBBEAN IS FORECAST TO
LIFT NORTHWARD ALONG THE FRONTAL BOUNDARY TOWARD THE SOUTHEAST
FLORIDA COAST INTO WEDNESDAY NIGHT. THIS WILL BRING ENHANCED SHOWER
AND STORM CHANCES...WITH POTENTIAL FOR HEAVY RAINS AND DETERIORATING
BOATING CONDITIONS. INTERESTS IN EAST CENTRAL FLORIDA ARE URGED TO
CLOSELY MONITOR THE PROGRESS OF THE LOW.

AFTER THE TROPICAL SYSTEM DEPARTS LATE THIS WEEK...HAZARDOUS BOATING
CONDITIONS WILL PERSIST INTO THE WEEKEND BUT SHOWER AND STORM
CHANCES WILL BE REDUCED AS A SLIGHTLY LESS HUMID AIR MASS IS
FORECAST TO MOVE INTO THE AREA.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF
NEEDED.

HEAVY RAINFALL CAN BE EXPECTED...CAUSING TEMPORARY PONDING ON SOME

WILL VARY FROM 1 TO 3 INCHES AND LOCALLY MORE. MOTORISTS SHOULD SLOW
