THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
AN AREA OF THUNDERSTORMS DEVELOPING OVER THE CENTRAL AND EASTERN
GULF OF MEXICO LATE THIS MORNING WILL MOVE TOWARD THE FLORIDA
PENINSULA THIS AFTERNOON...THEN ACROSS THE PENINSULA OVERNIGHT.
ADDITIONAL SHOWERS AND STORMS ARE FORECAST TO FORM OUT AHEAD OF
THE MAIN BAND BETWEEN LATE AFTERNOON AND SUNSET.

THE LOCAL AIR MASS IS FORECAST TO BECOME INCREASINGLY MOIST AND
UNSTABLE WITH INCREASING LOW LEVEL WINDS AND SHEAR...AND THIS WILL
ALLOW SOME OF THE STORMS THAT DEVELOP TO BEGIN TO ROTATE AS THEY
PUSH ACROSS THE PENINSULA FROM TONIGHT. IN ADDITION...COLD AND DRY
AIR ALOFT WILL AID IN HAIL FORMATION AS WELL AS STRONG GUSTY WINDS.

STORMS ARE FORECAST TO BEGIN AFFECTING AREAS WEST OF THE ORLANDO
METRO AREA BETWEEN 3 AND 5 PM. THE STORMS ARE EXPECTED TO IMPACT THE
SPACE AND TREASURE COASTS STARTING THIS EVENING. SHOWERS AND
ISOLATED STORMS WILL CONTINUE SOUTHWARD THROUGH THE OVERNIGHT HOURS.
THE PRIMARY THREATS WILL BE DEADLY CLOUD TO GROUND LIGHTNING
STRIKES...STRONG WIND GUSTS OF 40 TO 50 MPH...AND SMALL HAIL. A FEW
STRONGER STORMS COULD PRODUCE DAMAGING WIND GUSTS OR EVEN ACQUIRE
SOME ROTATION...ESPECIALLY ALONG AND NORTH OF THE I-4 CORRIDOR.

PERSONS IN EAST CENTRAL FLORIDA SHOULD STAY INFORMED OF THE
WEATHER THIS AFTERNOON AND EVENING...ESPECIALLY IF OUTDOOR
ACTIVITIES ARE PLANNED. MAKE SURE ADEQUATE MEANS OF RECEIVING
WARNING INFORMATION ARE EASILY ACCESSIBLE.

...FLOOD IMPACT...
DEEP MOISTURE WILL PUSH ACROSS FLORIDA BY LATE AFTERNOON. THIS WILL
ALLOW SOME STORMS TO PRODUCE VERY HEAVY RAIN LATE THIS AFTERNOON AND
TONIGHT AHEAD OF AN APPROACHING COLD FRONT. RECENT HEAVY RAINS HAVE
SATURATED MUCH OF THE LAND ACROSS THE CENTRAL PENINSULA AND HAVE
REDUCED ITS ABILITY TO ABSORB ADDITIONAL WATER ...ESPECIALLY NORTH
OF THE ORLANDO METRO AREA. PONDING OF WATER OR URBAN TYPE FLOODING
MAY DEVELOP RAPIDLY IN SATURATED AREAS LATE THIS AFTERNOON.

...MARINE THUNDERSTORM GUST IMPACT...
NUMEROUS SHOWERS AND A FEW STORMS WILL MOVE ACROSS THE CENTRAL
FLORIDA PENINSULA LATE THIS AFTERNOON AND INCREASE IN COVERAGE
STARTING THIS EVENING. SOME OF THE STORMS MAY INTENSIFY AS THEY
APPROACH AND MOVE OFF THE EAST FLORIDA COAST AND WILL BE CAPABLE
OF PRODUCING WIND GUSTS GREATER THAN 35 KNOTS.

...WATERSPOUT IMPACT...
STRONG VEERING WINDS THROUGH THE LOW AND MID LEVELS OF THE
ATMOSPHERE WILL ALLOW SOME OF THE STORMS THAT DEVELOP TO BEGIN TO
ROTATE AS THEY PUSH ACROSS THE PENINSULA. WATERSPOUTS MAY DEVELOP
AS THESE STORMS APPROACH THE COAST.

...WIND AND SEA IMPACT...
A FRESH TO STRONG SOUTHEAST BREEZE WILL PREVAIL ACROSS THE LOCAL
ATLANTIC WATERS TODAY...GENERATING SEAS GREATER THAN 7 FEET OVER
THE OFFSHORE LEG.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
A LINE OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO BE ONGOING
EARLY MONDAY MORNING ACROSS EAST CENTRAL FLORIDA. A FEW OF THESE
STORMS MAY BE STRONG TO SEVERE. THE STORMS WILL MOVE OFFSHORE
THROUGH MID DAY AS A COLD FRONT SWEEPS ACROSS THE
PENINSULA. MARINE CONDITIONS WILL REMAIN HAZARDOUS ACROSS THE
OFFSHORE ATLANTIC WATERS THROUGH TUESDAY MORNING BEFORE WINDS AND
SEAS SUBSIDE INTO MID WEEK.

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