AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
635 PM EDT MON MAR 17 2008

.UPDATE...
THE WINDS LATE THIS AFTERNOON INTO EARLY THIS EVENING HAVE BEEN
AROUND 20 TO 25 KNOTS OVER THE ATLANTIC WATERS...AND AROUND 20
KNOTS OVER REST OF THE CWA WATERS. THE ONLY EXCEPTION TO THIS WAS
THE NEAR-SHORE GULF WATERS WHERE THEY WERE 15 TO 20 KNOTS. THESE
WIND SPEEDS SHOULD CONTINUE TONIGHT INTO TUESDAY MORNING. SO HAVE
ISSUED A SCA FOR THE LAKE AND OFFSHORE GULF WATERS AND A SCEC FOR
THE NEAR-SHORE GULF WATERS FOR TONIGHT INTO TUESDAY MORNING.

10 SECOND SWELLS WITH A HEIGHT OF 2 TO 3 FEET WERE ALREADY SHOWING
UP AT AT 41010 BOUY EARLY THIS EVENING. THE LATEST WAVEWATCH MODEL
ALSO SHOWS THE NORTHEAST SWELLS COMING IN EARLIER THAN FORECAST. SO
HAVE BROUGHT IN THE NORTHEAST SWELLS 6 HOURS SOONER THAN EARLIER
FORECASTED TO THE EAST COAST AREAS WHICH WILL BE TUESDAY MORNING
FOR PALM BEACH COAST...AND TUESDAY AFTERNOON FOR REST OF THE EAST
COAST BEACHES.

REST OF THE FORECAST LOOKS GOOD AT THIS TIME.

&&
UPDATE...54/BNB & 57/DG

.PREV DISCUSSION... /ISSUED 233 PM EDT MON MAR 17 2008/

DISCUSSION...MODELS IN VERY GOOD AGREEMENT ON SYNOPTIC PATTERN
OVER THE NEXT FEW DAYS. STRONG UPPER RIDGE THAT CURRENTLY EXTENDS
ACROSS THE FLA PENINSULA WILL HOLD FIRM THROUGH EARLY WEDNESDAY.
AT THAT TIME, THE RIDGE WILL BEGIN TO RETREAT EASTWARD IN RESPONSE
TO A STRONG UPPER TROUGH THAT WILL MOVE INTO THE SOUTHEAST U.S.
FROM THE DESERT SOUTHWEST. AT THE SURFACE, STRONG RIDGE CENTERED
OVER THE MID ATLANTIC COAST WILL SHIFT SOUTHEAST INTO THE ATLANTIC
BY LATE WEDNESDAY. THE MODELS ALSO HAVE SHOWN A SLIGHT INCREASE IN
LOW LEVEL WINDS WITH THE GFS FCST SOUNDING SHOWING 25 KT AT AROUND
1K FEET SO WILL NEED TO WATCH THIS CLOSELY FOR POSSIBLE WIND
ADVISORY ALONG THE E CST FOR TUESDAY. ALL IN ALL, THIS LAYS OUT A
DRY SHORT TERM FORECAST FOR OUR CWA WITH A SLOW WARMING TREND,
SLOW DECREASE IN WIND FIELD AND BACK TO ABOVE NORMAL TEMPERATURES
FOR MID MARCH.

IN THE EXTENDED, A WEAK COLD FRONT ASSOCIATED WITH THE
AFOREMENTIONED UPPER TROUGH WILL MOVE INTO CENT FLA WEDNESDAY NIGHT.
AS THE TROUGH PULLS WELL OFF TO THE NORTHEAST AND S FLA GETS BACK TO
NEAR PERFECT ZONAL FLOW, THE FRONT WILL STALL ACROSS S FLA BY LATE
THURSDAY AND REMAIN NEARLY STATIONARY THROUGH THE WEEKEND. NOW OF
COURSE, DEPENDING ON ITS EXACT POSITION WILL DETERMINE THE EXTENT
AND LOCATION OF ANY SHRA ACTIVITY BUT WILL FOR NOW LEAVE MENTION OF
ISOLD POPS IN THE FCST UNTIL WE GET CLOSER TO THE EVENT AND THE
MODELS HAVE A BETTER HANDLE ON THE FRONT AND MOISTURE CONTENT OF THE
ATMOSPHERE.

AVIATION...VFR CONDITIONS SHOULD PREVAIL REMAINDER OF THIS
AFTERNOON AND INTO EARLY TUESDAY. SFC WINDS WILL CONTINUE IN THE 15
TO 20 KTS RANGE WITH HIGHER GUSTS ACROSS ALL TERMINALS AS A SFC
HIGH PRESS MOVES OFF THE ATLC SEABOARD TIGHTENING THE LOCAL
PRESSURE GRADIENT.

MARINE...WIND AND SEAS WILL REMAIN HIGH ESPECIALLY FOR THE
ATLANTIC WATERS WITH SCA FOR ALL WATERS INCLUDING BISCAYNE BAY
THROUGH TUESDAY. SCEC WILL BE IN ORDER FOR LAKE OKEE AND THE
OFFSHORE GULF WATERS. LARGE SURFACE LOW WILL DEVELOP OFF THE NEW
ENGLAND COAST WITH THE WAVE WATCH MODEL SHOWING MODERATE TO
POSSIBLE LARGE SWELLS TO BEGIN AFFECTING PALM BEACH COAST BY
TUESDAY AFTERNOON WITH THE LARGEST SWELLS OCCURRING ON WEDNESDAY
BEFORE SUBSIDING INTO THURSDAY.

FIRE WEATHER...NO PROBLEMS OR CONCERNS.

...HIGH RISK OF RIP CURRENTS ATLANTIC BEACHES THROUGH MID WEEK...
...HAZARDOUS MARINE CONDITIONS THROUGH MID WEEK ACROSS GULF STREAM...
...MODERATE NORTHEAST SWELLS AFFECTING EAST COAST BY MID WEEK...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

RIP CURRENTS: EAST WINDS WILL CONTINUE TO INCREASE TODAY AS HIGH
PRESSURE MOVES ACROSS THE MID ATLANTIC STATES. WINDS ARE EXPECTED
TO BUILD TO 20 TO 25 MPH TODAY ALONG THE EAST COAST AND THIS WILL LEAD
TO A HIGH RISK OF RIP CURRENTS TODAY AND TONIGHT ESPECIALLY AT
TIME OF LOW TIDE WHICH WILL BE AROUND NOON AND MIDNIGHT.

WAVES: EAST WINDS TO NEAR 20 KNOTS ACROSS THE ATLANTIC WATERS
WILL CAUSE SEAS TO BUILD TO 7 TO 8 FEET TODAY IN THE GULF STREAM.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

WINDS ARE EXPECTED TO CONTINUE FROM THE EAST AT 20 MPH ON TUESDAY. THIS
ELEVATED WIND SPEED COUPLED WITH A NORTHEAST SWELL PROPAGATING
FROM A STORM SYSTEM MOVING INTO THE CANADIAN MARITIMES WILL LIKELY
KEEP THE RISK OF RIP CURRENTS HIGH TUESDAY THROUGH WEDNESDAY. THIS
SWELL EVENT MAY LEAD TO HIGHER THAN NORMAL TIDE LEVELS AND
COASTAL EROSION ALONG THE EAST COAST AND ESPECIALLY ALONG THE
SHORE OF PALM BEACH COUNTY AND POINTS NORTHWARD.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED.
