THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

...SEVERE THUNDERSTORM WATCH UNTIL 8 PM...

.THUNDERSTORM IMPACT...
AMPLE MOISTURE COMBINED WITH A WEAK SURFACE TROUGH AND AFTERNOON
HEATING WILL PRODUCE SCATTERED STRONG LIGHTNING STORMS OVER EAST
CENTRAL FLORIDA FROM MID TO LATE AFTERNOON. DEVELOPING STORMS WILL
MOVE TOWARD THE SOUTHEAST AROUND 15 TO 20 MPH AND THE STRONGER
STORMS WILL BE CAPABLE OF PRODUCING STRONG GUSTY WINDS ABOVE 50
MPH...FREQUENT LIGHTNING...TORRENTIAL RAINFALL AND SMALL HAIL. A
FEW STORMS MAY BECOME SEVERE...PRODUCING WIND GUSTS IN EXCESS OF
60 MPH ALONG WITH COIN SIZE HAIL...EXCESSIVE LIGHTNING ALONG WITH
A THE POSSIBILITY OF BRIEF TORNADOES.

MOVE INDOORS AT THE FIRST SIGN OF A THUNDERSTORM. IF YOU CAN HEAR
THUNDER...THEN LIGHTNING IS CLOSE ENOUGH TO STRIKE YOU.

.EXCESSIVE HEAT IMPACT...
HEAT INDICES OF 100 TO 105 DEGREES ARE OCCURRING ACROSS THE
MAINLAND OF EAST CENTRAL FLORIDA. TAKE FREQUENT BREAKS IF WORKING
OUTDOORS FOR AN EXTENDED PERIOD AND DRINK PLENTY OF WATER.

.MARINE THUNDERSTORM GUST IMPACT...
STORMS WILL AFFECT INLAND LAKES DURING THIS AFTERNOON...AND
POTENTIALLY THE INTRACOASTAL AND IMMEDIATE NEAR SHORE ATLANTIC
WATERS UNTIL AFTER SUNSET. BOATERS SHOULD REMAIN ALERT TO THE
POTENTIAL FOR STORMS APPROACHING FROM THE NORTH AND WEST AT AROUND
15 KNOTS. MOVE TO SAFE HARBOR IN ADVANCE OF ANY LIGHTNING STORMS.

.WATERSPOUT IMPACT...
BRIEF SPIN UPS OF FUNNEL CLOUDS INCLUDING DAMAGING WATERSPOUTS
WILL BE POSSIBLE IN ANY LIGHTNING STORMS. THIS WILL BE MOST
PREVALENT AT THE ATLANTIC COAST AND THE BARRIER ISLANDS DUE TO THE
INTERACTIONS OF THE MARINE ENVIRONMENT WITH DEVELOPING AND ONGOING
STORMS JUST INLAND.

.FIRE WEATHER IMPACT...
THE COMBINATION OF DRY FUEL CONDITIONS COUPLED WITH AFTERNOON
RELATIVE HUMIDITY VALUES IN THE 40S AND THE THREAT FOR AFTERNOON
LIGHTNING STORMS WILL RESULT IN A MODERATE FIRE WEATHER DANGER
TODAY.

SEVERAL LIGHTNING-INITIATED FIRES HAVE OCCURRED OVER THE PAST FEW DAYS
...AND MORE IGNITIONS FROM LIGHTNING CAN BE EXPECTED THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
THERE WILL BE A SLIGHT CHANCE FOR AFTERNOON AND EARLY EVENING
LIGHTNING STORMS FROM WEDNESDAY THROUGH FRIDAY...WITH COVERAGE
INCREASING THIS WEEKEND.

THE FIRE DANGER WILL REMAIN ELEVATED UNTIL THE PATTERN OF HIGHER
COVERAGE OF AFTERNOON RAINFALL ESTABLISHES ITSELF IN EAST CENTRAL
FLORIDA.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS SHOULD MONITOR THE WEATHER. FORMAL ACTIVATION MAY BE
NEEDED.
