THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
DAYTIME HEATING COUPLED WITH A MOIST SOUTHERLY WIND FLOW AND
AFTERNOON SEA AND LAKE BREEZES WILL LEAD TO SCATTERED LIGHTNING
STORMS ACROSS EAST CENTRAL FLORIDA AND THE ADJACENT NEAR SHORE
ATLANTIC WATERS...MAINLY DURING THE AFTERNOON AND EVENING. STORM
COVERAGE WILL BE HIGHEST BETWEEN ABOUT 3 PM AND 9 PM AS ACTIVITY
ALONG AND AHEAD OF THE WEST COAST SEA BREEZE MOVES NORTHEAST AT 15
TO 20 MPH AND INTERACTS WITH THE EAST COAST SEA BREEZE AND ANY
STORMS WHICH FORM ALONG IT.

TODAY'S STRONGER STORMS WILL BE CAPABLE OF PRODUCING STRONG GUSTY
WINDS ABOVE 40 MPH AND COIN SIZED HAIL. ANY FLORIDA THUNDERSTORM
CAN PRODUCE TORRENTIAL DOWNPOURS AND FREQUENT CLOUD TO GROUND
LIGHTNING.

.MARINE THUNDERSTORM GUST IMPACT...
WITH STORMS MOVING TOWARD THE NORTHEAST AT AROUND 15 KNOTS...
ANY STORM WHICH FORMS INLAND WILL MOVE ACROSS THE INTRACOASTAL
WATERWAY AND INTO THE NEAR SHORE ATLANTIC. WIND GUSTS OF 35 KNOTS
OR GREATER WILL BE POSSIBLE IN SOME OF THE STORMS. BOATERS SHOULD BE
ON THE LOOKOUT FOR STORMS APPROACHING FROM THE WEST AND SOUTHWEST.

.WATERSPOUT IMPACT...
WITH DEEP MOISTURE IN PLACE...ANY BOUNDARY COLLISIONS NEAR THE EAST
COAST COULD PRODUCE A WATERSPOUT THAT WOULD AFFECT THE INTRACOASTAL
AND NEAR SHORE ATLANTIC WATERS.

.RIP CURRENT IMPACT...
THE DEVELOPMENT OF A LONG PERIOD SWELL OF 3 FEET COUPLED WITH AN
APPROACHING NEW MOON TOMORROW WILL RESULT IN A HIGH RISK OF RIP
CURRENTS AT THE ATLANTIC BEACHES TODAY. THE THREAT WILL BE
GREATEST DURING THE OUTGOING TIDE FROM MID TO LATE MORNING.

.FIRE WEATHER IMPACT...
GIVEN THE PERSISTENT DRY CONDITIONS...A HIGH TO VERY HIGH FIRE
DANGER EXISTS ACROSS MOST OF EAST CENTRAL FLORIDA. WITH INCREASING
CHANCES FOR LIGHTNING STORMS WITH GUSTY WINDS IN THE FORECAST...
NEW IGNITIONS WILL BE POSSIBLE. ANY NEW OR SMOLDERING FIRES WILL BE
CAPABLE OF SPREADING QUICKLY.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
A LOW PRESSURE CENTER WILL FORM OVER THE CENTRAL GULF OF MEXICO
EARLY SATURDAY AS A STRONG UPPER LEVEL DISTURBANCE DROPS UNUSUALLY
FAR SOUTH INTO THE GULF OF MEXICO. THIS LOW WILL TRACK EASTWARD
OVER FLORIDA BY SUNDAY MORNING. AS A RESULT...COVERAGE OF SHOWERS
AND STORMS WILL BE HIGH THIS WEEKEND...ESPECIALLY BETWEEN SATURDAY
AFTERNOON AND EARLY SUNDAY MORNING.

WHILE THERE REMAIN SOME DIFFERENCES IN THE TRACK...TIMING AND
INTENSITY...ANYTIME THERE IS A FAIRLY STRONG LOW IN THE GULF OF
MEXICO...THE POTENTIAL IS THERE FOR SEVERE WEATHER TO DEVELOP AND
IMPACT EAST CENTRAL FLORIDA. THUS...THERE REMAINS THE POSSIBILITY
FOR AN ORGANIZED SQUALL LINE TO FORM OVER THE CENTRAL AND EASTERN
GULF OF MEXICO AND AFFECT FLORIDA BETWEEN LATE SATURDAY AFTERNOON
AND EARLY SUNDAY MORNING.

PERSONS IN EAST CENTRAL FLORIDA SHOULD CLOSELY MONITOR THE WEATHER
INTO THIS WEEKEND. LISTEN FOR LATER STATEMENTS...FORECASTS...IMPACT
WEATHER UPDATES...AND HAZARDOUS WEATHER OUTLOOKS WHICH WILL REFINE
THE EXPECTED TIMING AND IMPACTS FROM THIS STORM SYSTEM.

BOATING CONDITIONS WILL BECOME HAZARDOUS THIS WEEKEND DUE TO
INCREASING WINDS AND SEAS...AND HIGHER COVERAGE OF STORMS. WINDS
AND SEAS ARE FORECAST TO REMAIN HAZARDOUS MONDAY AS A BRIEF SURGE
OF NORTHEAST WINDS PUSHES SOUTH THROUGH THE WATERS.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS SHOULD MONITOR WEATHER CONDITIONS TODAY AND REPORT ANY
COIN-SIZED HAIL...WIND DAMAGE...OR WATERSPOUTS OR FUNNEL CLOUDS.
ADDITIONALLY...SPOTTERS SHOULD KEEP ABREAST OF THE LATEST
INFORMATION REGARDING THE STORM FORECAST TO DEVELOP IN THE GULF OF
MEXICO BY EARLY SATURDAY.
