ISOLATED AMOUNTS OF 3-5" POSSIBLE. A FLOOD WATCH HAS BEEN ISSUED

...SCATTERED THUNDERSTORMS THIS EVENING AND AGAIN LATE TONIGHT...
...STRONG TO SEVERE THUNDERSTORMS POSSIBLE LATE TONIGHT THROUGH THIS WEEKEND...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TONIGHT

THUNDERSTORMS: THERE IS A CHANCE OF THUNDERSTORMS THIS EVENING
MAINLY OVER THE EASTERN HALF OF THE SOUTH FLORIDA PENINSULA. LATE
TONIGHT, AN AREA OF SHOWERS AND THUNDERSTORMS OVER THE GULF IS
EXPECTED TO MOVE EAST INTO THE REGION. THE MAIN IMPACT FROM ANY
STORMS WILL BE FREQUENT CLOUD TO GROUND LIGHTNING STRIKES, LOCALLY
HEAVY RAIN, AND GUSTY WINDS.

WATERSPOUTS: INCREASING SHOWERS AND THUNDERSTORMS OVER THE GULF
WATERS LATE TONIGHT ALONG WITH FAVORABLE WIND PROFILES WILL LEAD
TO A SLIGHT RISK OF WATERSPOUTS OFF THE SOUTHWEST FLORIDA COAST.

WIND: ANY THUNDERSTORMS THIS EVENING AND AGAIN OVERNIGHT WILL BE CAPABLE
OF PRODUCING WIND GUSTS TO AROUND 45 TO 50 MPH.

RIP CURRENTS: MODERATE SOUTHEASTERLY WINDS WILL CREATE A MODERATE
RISK OF RIP CURRENTS ALONG THE ATLANTIC COAST BEACHES.

FLOODING: ANY THUNDERSTORMS OR HEAVY SHOWERS THIS EVENING AND
OVERNIGHT WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL WITH
LOCALIZED MINOR FLOODING OF LOW LYING AND POOR DRAINAGE AREAS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

SEVERE THUNDERSTORMS AHEAD OF A STRONG DEVELOPING COLD FRONT MAY
OCCUR ACROSS SOUTH FLORIDA THIS WEEKEND. ACCORDING TO THE LATEST
FORECAST, CONDITIONS COULD BE MOST FAVORABLE LATER ON SATURDAY
INTO EARLY SUNDAY. AT THIS TIME, ANY SEVERE THUNDERSTORMS THAT
DEVELOP COULD SUPPORT ISOLATED TORNADOES, DAMAGING WIND GUSTS AND
POSSIBLY LARGE HAIL. FORECAST DETAILS ON THIS POTENTIAL SEVERE
WEATHER WILL BE FURTHER REFINED, SO STAY TUNED TO THE LATEST
FORECAST UPDATES.

MARINE CONDITIONS WILL ALSO DETERIORATE AHEAD OF THE FRONT AS EARLY
AS SATURDAY EVENING WITH SMALL CRAFT ADVISORY CONDITIONS LIKELY BY
EARLY SUNDAY AS WINDS AND SEAS INCREASE ACROSS LOCAL GULF AND
ATLANTIC WATERS.

MINOR COASTAL FLOODING IS POSSIBLE SATURDAY NIGHT THROUGH SUNDAY
NIGHT ALONG THE GULF COASTAL AREAS FROM MARCO ISLAND TO EVERGLADES
CITY AS WATER LEVEL REACH BETWEEN 1 AND 2 FEET ABOVE REGULAR HIGH
TIDE.

THE RISK OF RIP CURRENTS WILL INCREASE OVER THE WEEKEND ON BOTH THE
ATLANTIC AND GULF COAST BEACHES AHEAD OF A STRONG COLD FRONT.
