...NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON...
...A FEW STRONG THUNDERSTORMS POSSIBLE...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THUNDERSTORMS: SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED
TO DEVELOP THROUGH THE AFTERNOON HOURS ACROSS ALL OF SOUTH
FLORIDA. FREQUENT LIGHTNING AND LOCALLY HEAVY RAINFALL CAN BE
EXPECTED WITH MOST STORMS. THE STRONGEST STORMS MAY PRODUCE SMALL
HAIL AND GUSTY WINDS.

HAIL: SMALL HAIL IS POSSIBLE TODAY WITH THE STRONGEST STORMS.

WINDS: GUSTY WINDS OF 40 TO 50 MPH WILL BE POSSIBLE WITH MANY
STORMS TODAY.

WATERSPOUTS: WATERSPOUTS ARE POSSIBLE OVER ALL SOUTH FLORIDA
WATERS TODAY.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

THE RISK OF RIP CURRENTS ALONG THE ATLANTIC COAST MAY INCREASE
LATE THIS WEEKEND. THE RISK WILL LIKELY INCREASE INTO NEXT WEEK.

SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE FORECAST EACH
DAY, ESPECIALLY DURING THE AFTERNOONS AND EVENINGS. A FEW STRONG
STORMS WILL BE POSSIBLE, WITH FREQUENT LIGHTNING AND GUSTY WINDS
THE MAIN THREATS.

THE NATIONAL HURRICANE CENTER CONTINUES TO MONITOR THE PROGRESS OF
DANGEROUS MAJOR HURRICANE MATTHEW, CURRENTLY MOVING THROUGH THE

THERE REMAINS A GREAT DEAL OF UNCERTAINTY ON THE POTENTIAL
IMPACTS OF HURRICANE MATTHEW FOR SOUTH FLORIDA, ESPECIALLY TO THE
MAINLAND. HOWEVER, CONFIDENCE IS INCREASING IN DETERIORATING
MARINE CONDITIONS FOR THE ATLANTIC WATERS STARTING TUESDAY, WITH
THE POTENTIAL FOR HAZARDOUS CONDITIONS TO LINGER THROUGH MUCH OF
THE WEEK. THESE ADVERSE MARINE CONDITIONS MAY ALSO BRING BEACH
EROSION AND COASTAL FLOODING CONCERNS. THE EXACT NATURE OF THESE
IMPACTS WILL GREATLY DEPEND ON THE TRACK, STRENGTH, AND TIMING OF
THE SYSTEM.

NOW IS THE TIME TO REVIEW HURRICANE PREPAREDNESS PLANS AND TO
MAKE SURE YOUR HURRICANE SUPPLIES ARE FULLY STOCKED. INTERESTS IN
SOUTH FLORIDA SHOULD CONTINUE TO REMAIN WELL INFORMED ON THE
FORECAST REGARDING HURRICANE MATTHEW WITH THE LATEST INFORMATION
FROM THE NATIONAL HURRICANE CENTER AND NATIONAL WEATHER SERVICE
MIAMI.
