..MAJOR HURRICANE IRENE PASSING EAST OF FLORIDA TODAY INTO TONIGHT...
..RECORD HIGHS EAST COAST METRO AREAS THIS WEEKEND...
TROPICAL SYSTEMS/SHORT TERM...
THE NATIONAL HURRICANE CENTER CONTINUES TO FORECAST MAJOR
HURRICANE IRENE TO MOVE TO THE NORTHWEST TODAY THROUGH THE
NORTHWEST BAHAMA ISLANDS BEFORE TURNING NORTHWARD INTO THE
NORTHWEST ATLANTIC WATERS TONIGHT. THIS WILL KEEP THE TROPICAL
STORM FORCE WINDS WELL EAST OF MAINLAND SOUTH FLORIDA...BUT WIND
SPEEDS WILL BE FROM BREEZY CONDITIONS ALONG THE WEST COAST METRO
AREAS TO WINDY CONDITIONS ALONG THE EAST COAST METRO AREAS.
THE OUTER FEEDER BANDS WERE APPROACHING THE OFFSHORE ATLANTIC WATERS
EARLY THIS MORNING. THESE FEEDER BANDS WILL CONTINUE TO MOVE
ACROSS THE ATLANTIC WATERS THROUGH THE MORNING HOURS AND MOVE
INTO THE EAST COAST METRO AREAS LATE THIS MORNING INTO THE
AFTERNOON HOURS. REST OF THE CWA WILL SEE ISOLATED TO SCATTERED
SHOWERS MAINLY IN THE AFTERNOON HOURS...DUE TO THE HEATING OF THE
DAY ALONG WITH LOW LEVEL MOISTURE INCREASING. THEREFORE...THE POPS
WILL RANGE FROM 30 PERCENT ALONG THE WEST COAST METRO AREAS OF THE
CWA INCREASING TO 60 PERCENT ALONG THE EAST COAST METRO AREAS FOR
TODAY.
AS HURRICANE IRENE CONTINUES TO MOVE NORTHWARD TONIGHT INTO
FRIDAY...DRIER AIR WILL BE WORKING INTO SOUTH FLORIDA FROM THE
GULF OF MEXICO. THIS WILL ALLOW FOR THE FEEDER BANDS OVER THE
ATLANTIC AND EAST COAST METRO AREAS TO SLOWLY DISSIPATE.
THEREFORE...THE POPS WILL BE ON A DOWNWARD TREND TONIGHT INTO
FRIDAY AND BY FRIDAY AFTERNOON BE AROUND 10 TO 20 PERCENT ACROSS
THE CWA.
THE WIND SPEEDS WILL ALSO SLOWLY DECREASE TONIGHT INTO FRIDAY...AND BY
FRIDAY NIGHT BE DOWN TO LESS THAN 15 KNOTS OVER THE MAINLAND AREAS
OF SOUTH FLORIDA.
TOTAL RAINFALL AMOUNTS WITH HURRICANE IRENE WILL BE AROUND TENTH
OF AN INCH AROUND THE WEST COAST METRO AREAS TO HALF AN INCH TO
ONE INCH OVER THE EAST COAST METRO AREAS. SO NO FLOODING CONCERNS
FROM THE RAINFALL EVENT OVER SOUTH FLORIDA.
FOR THE WEEKEND...THE SOUTHWEST WIND FLOW WILL CONTINUE OVER SOUTH
FLORIDA AS HURRICANE IRENE CONTINUES TO MOVE NORTH TO NORTHEAST
AWAY FROM FLORIDA. THIS WILL KEEP THE DRY AIR IN PLACE FOR
SATURDAY...BUT ALLOWING FOR A SOME LOW LEVEL MOISTURE TO WORK
INTO THE CWA FOR SUNDAY. SO WILL CONTINUE ONLY A SLIGHT CHANCE OF
SHOWERS OVER THE CWA ON SATURDAY...AND THEN BRING BACK A SLIGHT
CHANCE OF THUNDERSTORMS TO THE AREA FOR SUNDAY EXCEPT CHANCE FOR
THE EAST COAST METRO AREAS.
THE SOUTHWEST WIND FLOW WILL ALSO ALLOW FOR HIGHS THIS WEEKEND TO
BE IN THE MID 90S OVER MOST OF THE CWA...EXCEPT UPPER 90S TO NEAR
100 OVER THE EAST COAST METRO AREAS. THESE HIGHS ARE RECORD HIGHS
FOR THIS TIME OF YEAR FOR THE EAST COAST METRO AREAS...AND MORE
INFORMATION WILL BE DISCUSS IN THE CLIMATE SECTION BELOW.
LONG TERM...
THE SOUTHWEST STEERING FLOW REMAIN IN PLACE FOR EARLY NEXT WEEK AS
A TROUGH OF LOW PRESSURE OVER THE CENTRAL UNITED STATES MOVES EAST
INTO THE EASTERN UNITED STATES. THIS WILL KEEP THE SOUTHWEST
STEERING FLOW OVER SOUTH FLORIDA...AND FOCUS THE HIGHEST POPS OVER
THE EASTERN AREAS OF THE CWA. HIGHS WILL ALSO BE IN THE LOWER TO
MID 90S OVER MOST OF THE CWA...EXCEPT MID TO UPPER 90S EAST COAST
METRO AREAS WHICH ARE NEAR THE RECORD HIGHS FOR THIS TIME OF YEAR.
BY MIDDLE OF NEXT WEEK...THE TROUGH WILL MOVE EAST INTO THE
ATLANTIC WATERS ALLOWING FOR HIGH PRESSURE TO BUILD BACK INTO
SOUTH FLORIDA FROM THE SOUTH. THIS WILL ALLOW FOR THE STEERING
FLOW TO BECOME EASTERLY OVER THE CWA AND FOCUS THE HIGHEST POPS
OVER THE INTERIOR AND WEST COAST AREAS.
MARINE...
NORTHEAST SURFACE WINDS WILL BEGIN TO INCREASE QUICKLY AND SEAS
WILL BECOME ROUGH IN RESPONSE TO THE APPROACH OF IRENE THIS
MORNING WITH TROPICAL STORM CONDITIONS ACROSS THE NORTHERN
PORTIONS OF THE ATLANTIC WATERS THIS AFTERNOON INTO TONIGHT. THERE
IS A TROPICAL STORM WARNING IN EFFECT FOR THE OFFSHORE PALM BEACH
WATERS THROUGH FRIDAY MORNING...AND A TROPICAL STORM WATCH AND A
SCA IN EFFECT FOR REST OF THE ATLANTIC WATERS. A SCA IS ALSO IN
EFFECT FOR BISCAYNE BAY AND LAKE OKEECHOBEE WATERS THROUGH FRIDAY
MORNING...AND A SCEC FOR THE GULF WATERS THROUGH FRIDAY MORNING.
MARINERS AND BOATERS ACROSS SOUTH FLORIDA SHOULD CONTINUE TO
MONITOR IRENE AND KEEP ABREAST OF THE LATEST UPDATES ISSUED BY THE
NATIONAL HURRICANE CENTER AND THIS OFFICE.
AS IRENE MOVES TO THE NORTH OF THE LOCAL WATERS ON FRIDAY INTO
SATURDAY...NORTH SWELLS MAY BEGIN TO AFFECT AT LEAST PALM BEACH
ATLANTIC WATERS. THIS WILL BE MONITORED THROUGH TODAY...AND A HIGH
SURF ADVISORY COULD BE NEED FOR THE COASTAL AREAS OF PALM BEACH
COUNTY LATER TODAY OR TONIGHT.
THERE IS ALSO A HIGH RISK OF RIP CURRENTS IN AFFECT FOR THE EAST
COAST BEACHES OF SOUTH FLORIDA TODAY INTO TONIGHT...DUE TO THE
WINDY TO VERY WIND CONDITIONS AND ROUGH SURF CONDITIONS.
