...INCREASED RISK OF RIP CURRENTS EAST COAST BEACHES THIS WEEKEND...
...THUNDERSTORMS RETURN TO AREA LATE THIS WEEKEND INTO EARLY NEXT WEEK...

.DISCUSSION...
THE STATIONARY FRONT OVER SOUTH FLORIDA WILL CONTINUE TO
DISSIPATE THIS AFTERNOON INTO THIS EVENING...AS HIGH PRESSURE
OVER THE SOUTHEAST UNITED STATES MOVES EAST INTO THE WESTERN
ATLANTIC WATERS TONIGHT. THIS WILL CONTINUE THE NORTHEAST TO EAST
WINDS OVER THE CWA THIS AFTERNOON INTO TONIGHT ALLOWING FOR
ISOLATED SHOWERS TO CONTINUE TO WORK INTO THE EAST COAST METRO
AREAS. SO WILL CONTINUE THE 10 TO 20 PERCENT POPS IN THESE AREAS.

THE WEST COAST SEA BREEZE WILL ALSO CONTINUE TO DEVELOP AND PUSH
SLOWLY INLAND THIS AFTERNOON OVER THE WEST COAST METRO AREAS OF
SOUTH FLORIDA. THIS WILL ALLOW FOR ISOLATED SHOWERS AND
THUNDERSTORMS TO DEVELOP OVER THE WESTERN SECTIONS OF SOUTH
FLORIDA LATE THIS AFTERNOON INTO EARLY THIS EVENING. SO WILL
CONTINUE THE 20 POPS OVER THE WESTERN SECTIONS OF THE CWA FOR
THIS AFTERNOON INTO THIS EVENING.

THE HIGH OVER THE WESTERN ATLANTIC WATERS WILL REMAIN NEARLY
STATIONARY THIS WEEKEND KEEPING THE EASTERLY WIND FLOW OVER THE
CWA...BUT WILL ALLOW FOR THE WINDS TO BECOME BREEZY...ESPEICALLY
OVER THE EAST COASTAL AREAS OF THE CWA. THIS IN TURN WILL ALLOW
FOR AN INCREASE IN THE RISK OF RIP CURRENTS ALONG THE EAST COAST
BEACHES OF SOUTH FLORIDA THIS WEEKEND.

DEEPER MOISTURE WILL ALSO START TO RETURN TO THE AREA LATE THIS
WEEKEND ON THE EASTERLY WIND FLOW WHICH IN TURN WILL ALLOW FOR
ISOLATED SHOWERS OVER THE CWA ON SATURDAY...BEFORE THUNDERSTORMS
RETURN TO THE PICTURE FOR SUNDAY.

.EXTENDED FORECAST...
THE HIGH OVER THE WESTERN ATLANTIC WATERS WILL THEN MOVE SOUTH TO
JUST EAST OF THE BAHAMA ISLANDS FOR THE EARLY TO MIDDLE OF NEXT
WEEK...AS A COLD FRONT MOVES INTO CENTRAL FLORIDA FROM THE NORTH.
THIS WILL ALLOW FOR THE WINDS TO BECOME MORE SOUTHERLY OVER THE
CWA FOR EARLY TO MIDDLE OF NEXT WEEK...WHICH IN TURN WILL
CONTINUE TO BRING IN MORE MOISTURE TO THE AREA. SO WILL CONTINUE
WITH CHANCE POPS OVER THE CWA WITH THE HIGHEST CHANCE AROUND THE
LAKE OKEECHOBEE AREA FOR EARLY TO MIDDLE OF NEXT WEEK.

&&

.MARINE...
EASTERLY WINDS WILL CONTINUE OVER THE SOUTH FLORIDA WATERS
TONIGHT INTO THIS WEEKEND...AS THE WIND SPEEDS INCREASE TO 15 TO
20 KNOTS TONIGHT INTO SATURDAY. THE SPEEDS WILL THEN SLOWLY
DECREASE LATE THIS WEEKEND...AND BY EARLY NEXT WEEK BE LESS THAN
10 KNOTS FROM THE SOUTHERLY DIRECTION.

THE ATLANTIC SEAS WILL ALSO INCREASE TONIGHT AND BY SATURDAY BE 4
TO 6 FEET...BEFORE SLOWLY SUBSIDING TO LESS THAN 2 FEET BY EARLY
NEXT WEEK. FOR THE GULF SIDE...THE SEAS SHOULD REMAIN AT 4 FEET
OR LESS THROUGH THE WEEKEND INTO EARLY NEXT WEEK. SO WILL BE
PUTTING UP A SCEC CONDITIONS FOR ALL OF THE CWA WATERS FOR
TONIGHT.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITIES WILL REMAIN ABOVE THE 35 PERCENT CRITICAL
VALUE THROUGH THE WEEKEND OVER ALL OF SOUTH FLORIDA. SO NO
PROBLEMS ARE EXPECTED WITH THE FIRE WEATHER.
