...STRONG TO SEVERE STORMS POSSIBLE THROUGH SUNSET NORTH OF THE
INTERSTATE FOUR CORRIDOR THROUGH SUNSET...

...STORMS WILL SPREAD SOUTH AND INCREASE IN COVERAGE TONIGHT...

...THUNDERSTORM IMPACT...
A DEVELOPING SURFACE LOW PRESSURE AREA MOVING ACROSS GEORGIA COUPLED
WITH DEEP MOISTURE...INSTABILITY...AND STRONG WINDS FROM THE SURFACE
INTO THE UPPER LEVELS OF THE ATMOSPHERE...HAS LEAD TO DEVELOPMENT OF
NUMEROUS STRONG TO SEVERE THUNDERSTORMS ACROSS THE NORTHERN THIRD OF
FLORIDA THROUGH MID AFTERNOON. AS AN UPPER LEVEL DISTURBANCE SWEEPS
EASTWARD TONIGHT...EXPECT INCREASING COVERAGE OF STORMS THROUGH EARLY
EVENING NORTH OF INTERSTATE FOUR...AND CONTINUING INTO THE OVERNIGHT
HOURS AS IT SPREAD SOUTHWARD TOWARD ORLANDO...AND THE TITUSVILLE...
COCOA AND MELBOURNE AREAS.

PERSONS IN EAST CENTRAL FLORIDA SHOULD STAY ALERT OF THE WEATHER
THIS AFTERNOON AND INTO THIS EVENING AND BE PREPARED TO QUICKLY TAKE
SHELTER INDOORS SHOULD STORMS APPROACH YOUR LOCATION.

...FLOOD IMPACT...
A LONG FETCH OF DEEP MOISTURE WILL LEAD TO THE POTENTIAL FOR HEAVY
RAIN...ESPECIALLY ACROSS OSCEOLA COUNTY AND THE SPACE COAST NORTH TO
METRO ORLANDO...LAKE AND VOLUSIA COUNTIES. TRAINING OF STRONGER
STORMS WILL BE CAPABLE OF PRODUCING IN EXCESS OF TWO INCHES OF
RAINFALL IN A SHORT TIME...LEADING TO STANDING WATER AND HAZARDOUS
DRIVING CONDITIONS ON ROADS. PLACES THAT RECEIVED HEAVY RAINFALL
OVER THE PAST 24 HOURS NOT MENTIONED ABOVE WILL ALSO SEE THE THREAT
OF MINOR FLOODING FROM AFTERNOON AND EVENING STORMS.

...HIGH WIND IMPACT...
SOUTH WINDS WILL INCREASE TO 20 TO 25 MPH AND GUSTY WITH OCCASIONAL
GUSTS OF 35 MPH TODAY. THE STRONG AND GUSTY WINDS WILL CREATE ROUGH
AND HAZARDOUS BOATING CONDITIONS ON AREA LAKES AND THE INTRACOASTAL
WATERS. THIS MAY RESULT IN HIGH WAVES WHICH MAY TIP OR SWAMP SMALL
CRAFT.

...MARINE THUNDERSTORM GUST AND WATERSPOUT IMPACTS...
STRONG TO SEVERE STORMS WILL BE POSSIBLE OVER THE COASTAL WATERS
THIS EVENING AND OVERNIGHT AS A SQUALL LINE PUSHES OFFSHORE FROM THE
MAINLAND. THE HIGHEST CHANCE FOR STRONG MARINE STORMS WILL BE NORTH
OF SEBASTIAN INLET. LOW LEVEL WINDS WILL FAVOR THE POTENTIAL FOR THE
DEVELOPMENT OF A FEW WATERSPOUTS OVER THE INTRACOASTAL AND ATLANTIC
WATERS.

...WIND AND SEA IMPACT...
SOUTH WINDS WILL INCREASE TO 20 KNOTS AND GUSTY NEAR SHORE AND 20 TO
25 KNOTS OFFSHORE TODAY. SEAS WILL BUILD UP TO 6 TO 8 FEET OVER THE
OFFSHORE WATERS INTO TONIGHT. OCCASIONAL GUSTS TO GALE FORCE WILL BE
POSSIBLE ACROSS THE OFFSHORE WATERS TONIGHT OUTSIDE OF STRONG
CONVECTION.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
WINDY AND DRY CONDITIONS WILL DEVELOP ON SATURDAY AFTER THE PASSAGE
OF A STRONG COLD FRONT. THERE WILL BE A HIGH WILD FIRE DANGER DUE TO
GUSTY WINDS AND RELATIVE HUMIDITY IN THE AFTERNOON. LOW RELATIVE
HUMIDITY CONCERNS WILL CONTINUE ACROSS MUCH OF EAST CENTRAL FLORIDA
AGAIN ON SUNDAY.

TEMPERATURES WILL BE QUITE COOL SATURDAY NIGHT AS MID TO UPPER
30S ARE EXPECTED OVER MUCH OF INLAND CENTRAL FLORIDA BY DAYBREAK
SUNDAY. HAZARDOUS BOATING CONDITIONS WILL PERSIST OFFSHORE OVER
THE ATLANTIC WATERS INTO SUNDAY.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS NETWORKS ARE REQUESTED TO MONITOR THE WEATHER AND SELF
ACTIVATE IF NEEDED...ESPECIALLY FROM POINTS...LAKE...ORANGE AND
NORTHERN BREVARD COUNTIES NORTHWARD. THIS THREAT WILL SPREAD
SOUTHWARD LATE THIS AFTERNOON AND THROUGH THE OVERNIGHT PERIOD.
