THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
HIGH PRESSURE SHIFTING FARTHER OUT INTO THE ATLANTIC TODAY WILL
PRODUCE A SOUTHERLY WIND FLOW, WHICH WILL TAP A MUCH MORE MOIST
AIR MASS. THIS WILL LEAD TO SCATTERED TO NUMEROUS SHOWERS AND
SCATTERED THUNDERSTORMS DURING THE AFTERNOON AND EVENING AS
SEA BREEZE AND OUTFLOW BOUNDARIES INTERACT. A FEW STRONG STORMS
WITH FREQUENT TO EXCESSIVE LIGHTNING STRIKES, TORRENTIAL DOWNPOURS
AND GUSTY WINDS TO AROUND 40 MPH ARE EXPECTED. MOVEMENT SHOULD BE
TOWARDS THE NORTH OR NORTHEAST AT 5 TO 10 MPH.

.FLOOD IMPACT...
A FEW OF THE STRONGER AND SLOWER MOVING STORMS WILL BE CAPABLE OF
PRODUCING 2 TO 3 INCHES OF RAINFALL IN A SHORT PERIOD OF TIME,
WHICH WOULD CAUSE CONSIDERABLE PONDING OF WATER ON ROADWAYS AND
OTHER POORLY DRAINED AREAS.

.RIP CURRENT IMPACT...
A LINGERING OCEAN SWELL WILL KEEP A MODERATE RIP CURRENT RISK AT
AREA BEACHES. THE STRONGEST SEAWARD PULL IS EXPECTED TO BE FROM
AROUND MIDDAY THROUGH LATE AFTERNOON DUE TO TIDAL EFFECTS. ONLY
SWIM IN THE OCEAN NEAR A LIFEGUARD.

.MARINE THUNDERSTORM GUST IMPACT...
STORMS FORMING OVER LAND WILL MOVE NORTH TO NORTHEAST AROUND 10
KNOTS THIS AFTERNOON. A FEW COULD PRODUCE GUSTY WINDS TO 35 KNOTS
AND FREQUENT LIGHTNING STRIKES OVER THE INTRACOASTAL AND NEARSHORE
ATLANTIC WATERS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
TROPICAL DEPRESSION NUMBER THREE IN THE SOUTHERN GULF OF MEXICO IS
FORECAST TO LIFT NORTH THROUGH MONDAY, THEN TURN NORTHEASTWARD AND
CROSS THE NORTHERN FLORIDA PENINSULA MONDAY NIGHT INTO EARLY TUESDAY.

BASED ON THE CURRENT FORECAST, THIS SYSTEM WILL LIKELY BRING A THREAT
FOR HEAVY RAINFALL, STRONG GUSTY WINDS, SEVERE OR TORNADIC STORMS
AND HAZARDOUS BOATING CONDITIONS TO EAST CENTRAL FLORIDA MONDAY
INTO TUESDAY.

PEOPLE ACROSS EAST CENTRAL FLORIDA ARE URGED TO MONITOR THE PROGRESS
OF THIS DEVELOPING WEATHER SYSTEM. BE PREPARED TO ACTIVATE YOUR
PERSONAL SEVERE WEATHER PLAN, SHOULD IT BECOME NECESSARY.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.
