DISCUSSION...
A STATIONARY FRONT CONTINUES TO LINGER ACROSS THE FLORIDA STRAITS
AND ACROSS THE NORTHERN BAHAMAS ISLANDS INTO THE WESTERN ATLANTIC.
LOW LEVEL SOUTHEASTERLY FLOW WILL CONTINUE TO BRING THE BOUNDARY
MOISTURE ACROSS THE REGION TODAY THROUGH TONIGHT AND INTO SUNDAY.
UPPER LEVEL SOUTHWESTERLY FLOW ACROSS THE GULF AND FLORIDA PENINSULA
WILL CONTINUE TO BRING MID TO UPPER LEVEL MOISTURE FROM THE YUCATAN
PENINSULA AND ACROSS THE GULF AND INTO THE REGION THIS AFTERNOON AND
TONIGHT. THE POTENTIAL FOR CONVECTION ACROSS THE REGION WILL
LINGER THROUGH TONIGHT AS THE DEEP LAYERED BOUNDARY MOISTURE
PERSISTS ACROSS THE AREA...WITH FORECAST PWATS EXPECTED TO BE
AROUND 2.3 INCHES AND PERSISTING INTO SUNDAY. BUT BY SUNDAY
AFTERNOON THE UPPER LEVEL CONDITIONS WILL BE LESS FAVORABLE TO
SUSTAIN CONVECTION AS A WEAK UPPER LEVEL RIDGE BEGINS TO BUILD
ACROSS THE SOUTH FLORIDA PENINSULA. HOWEVER THE LINGERING MOISTURE
AND DAY TIME HEATING SHOULD RESULT IN SCATTERED SHOWERS AND
THUNDERSTORMS POSSIBLE ACROSS THE REGION. BY MONDAY THE PWATS
DECREASE TO ABOUT 2 INCHES AND THE UPPER LEVEL RIDGE STRENGTHENS
WITH ZONAL MID TO UPPER LEVEL FLOW BEING ESTABLISHED ACROSS THE
REGION...WITH A FEW SCATTERED SHOWERS AND THUNDERSTORMS POSSIBLE
ACROSS SOUTH FLORIDA AND SURROUNDING WATERS.

FLOODING AND EVEN THE POSSIBILITY OF WATER ENTERING STRUCTURES
IS POSSIBLE, ESPECIALLY IN THE HOLLYWOOD AREA, WHERE 5 INCHES

POORLY DRAINED AREAS IS POSSIBLE DUE TO THE RECENT LOCALLY

THE SOUTHEAST COAST OVERNIGHT. A FEW LIGHTNING STRIKES AND
HEAVY RAINFALL WILL BE THE MAIN HAZARDS FROM THE STORMS.

RIP CURRENTS: EAST NORTHEAST WINDS INCREASING TO 15 TO 20 KNOTS
WILL CREATE A MODERATE RISK OF RIP CURRENTS AT THE BEACHES OF PALM
BEACH, BROWARD AND MIAMI DADE COUNTIES TONIGHT

WAVES: INCREASING EAST NORTHEAST WINDS TO 15 TO 20 KNOTS WILL
ALLOW SEAS TO BUILD UP TO 7 FEET IN THE GULF STREAM TONIGHT.

MIDDLE OF NEXT WEEK. THE PRIMARY IMPACTS FROM THE STORMS WILL BE

INTO NEXT WEEK, THIS WILL LEAD TO AN INCREASING RISK OF DANGEROUS
RIP CURRENTS ALONG THE ATLANTIC BEACHES.
