MARINE WEATHER DISCUSSION FOR THE GULF OF MEXICO...CARIBBEAN
SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND
64W...AND THE SW N ATLANTIC INCLUDING THE BAHAMAS.

...GULF OF MEXICO...

MODEL PREFERENCE: LATEST GFS AND ECMWF BLENDED WITH PREVIOUS
OFFICIAL FORECAST. LATEST MWW3 USED FOR WAVE PARAMETERS
(NWPS NOT AVAILABLE). HIGH CONFIDENCE.

A WEAK 1017 MB HIGH PRES AREA LOCATED IN THE NE GULF DOMINATES
THE REGION. THIS HIGH IS EXPECTED TO MEANDER OVER THE N-CENTRAL
AND NE GULF THROUGH LATE TONIGHT AND MERGE WITH A RIDGE MOVING
OFF THE MID-ATLC COAST ON FRI WHICH WILL ARRIVE BEHIND THE TAIL
END OF A WEAK COLD FRONT. AS THIS NEW RIDGE BUILDS ACROSS THE
AREA...GENTLE TO MODERATE NE-E WINDS WILL PREVAIL ACROSS THE
EASTERN GULF WITH MAINLY MODERATE E-SE WINDS ACROSS THE WESTERN
GULF. ALSO...FRESH TO LOCALLY STRONG WINDS WILL CONTINUE TO PULSE
EACH EVENING THROUGH THE EARLY MORNING HOURS NEAR AND TO THE NW OF
THE YUCATAN PENINSULA DUE TO LOCAL EFFECTS INDUCE BY A THERMAL
TROUGH. THESE E-SE PULSES OF 20-25 KT WILL PROPAGATE WNW ACROSS
THE SW GULF OF MEXICO EAST OF AN INVERTED TROUGH DURING THE
MORNING HOURS...WITH THE TROUGH LOSING IDENTITY AND WINDS
DIMINISHING TO 15-20 KT BY THE LATE MORNING/EARLY AFTERNOON HOURS
EACH DAY. SEAS WILL BRIEFLY BUILD TO 5-7 FT ACROSS THE SW GULF IN
ASSOCIATION WITH THESE WINDS. OTHERWISE...SEAS WILL BE GENERALLY
UNDER 6 FT ACROSS THE WESTERN GULF AND UNDER 4 FT ACROSS THE
EASTERN GULF.

THE PRES GRADIENT BETWEEN A 1030 MB HIGH OVER THE U.S. MIDDLE
ATLC STATES AND LOWER PRES OVER TEXAS AND NE MEXICO WILL BRING AN
INCREASE IN WINDS AND SEAS ACROSS THE GULF WATERS BY SAT NIGHT.
FRESH TO LOCALLY STRONG E-SE WINDS ARE EXPECTED ACROSS MOST OF THE
GULF WITH BUILDING SEAS TO 8 FT ACROSS THE NW PART BY SUN. THESE
MARINE CONDITIONS ARE FORECAST TO ALSO PERSIST ON MON...
DIMINISHING SLIGHTLY BY TUE AS THE PRES GRADIENT SLACKENS A BIT.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

MODEL PREFERENCE: LATEST GFS AND ECMWF BLENDED WITH PREVIOUS
OFFICIAL FORECAST. LATEST MWW3 USED FOR WAVE PARAMETERS
(NWPS NOT AVAILABLE). HIGH CONFIDENCE.

THE PRES GRADIENT BETWEEN RIDGING N OF AREA AND LOW PRES LOCATED
OVER NW COLOMBIA WILL CONTINUE TO SUPPORT THE PULSING OF FRESH TO
LOCALLY STRONG TRADE WINDS NEAR THE NW COAST OF COLOMBIA WITH
RECENT ASCAT AND ASCAT-B SCATTEROMETER PASSES AND A RECENT CRYOSAT
ALTIMETER PASS WHICH REGISTERED SEAS UP TO 8 FT VERIFYING THESE
CONDITIONS. OTHERWISE...MODERATE TO FRESH TRADES WILL PREVAIL
THROUGH SUN ACROSS THE REMAINDER OF THE AREA S OF 17N WHILE
MODERATE TRADES ARE EXPECTED N OF 17N.

WINDS AND SEAS WILL INCREASE E OF THE WINDWARD ISLANDS FRI
AFTERNOON AND PERSIST THROUGH SUN NIGHT. IN ADDITION...EXPECT
INCREASING WINDS AND SEAS ACROSS THE CENTRAL CARIBBEAN...IN THE
GULF OF HONDURAS...AND NEAR THE WINDWARD PASSAGE DURING THE
UPCOMING WEEKEND AS A STRONGER HIGH PRES MOVES ACROSS THE MIDDLE
ATLC STATES INTO THE WESTERN ATLANTIC. MODEL GUIDANCE SUGGESTS
TRADE WINDS OF 25-30 KT AND SEAS OF 10-12 FT NEAR THE COAST OF
COLOMBIA BY EARLY SUN MORNING WITH SIMILAR WEATHER CONDITIONS
PERSISTING MON THROUGH TUE.

...SW N ATLANTIC INCLUDING THE BAHAMAS...

MODEL PREFERENCE: LATEST GFS AND ECMWF BLENDED WITH PREVIOUS
OFFICIAL FORECAST. LATEST MWW3 USED FOR WAVE PARAMETERS
(NWPS NOT AVAILABLE). HIGH CONFIDENCE.

A 1019 MB HIGH PRES CENTER LOCATED NEAR 29N59W EXTENDS A RIDGE
WESTWARD ACROSS THE SW N ATLC OFFSHORE WATERS ALONG 26N/27N TO
NEAR JUPITER FLORIDA. RECENT SCATTEROMETER DATA SHOWED MAINLY
LIGHT TO MODERATE BREEZE ANTICYCLONIC FLOW ACROSS MOST OF THE
REGION WITH SEAS OF 2-4 FT E OF THE BAHAMAS BASED ON BUOY
OBSERVATIONS AND ALTIMETER PASSES. AN EXCEPTION IS ACROSS THE
WATERS NEAR HISPANIOLA AND W OF 70W WHERE THE MOST RECENT ASCAT
PASS VERIFIED THE EXISTENCE OF MODERATE TO FRESH EASTERLY WINDS
WHERE A LOCALIZED TIGHTER PRES GRADIENT IS PRESENT.

THE HIGH PRES AND RIDGE WILL WEAKEN TONIGHT THROUGH FRI NIGHT AS
WEAK TROUGHING DISRUPTS IT WHICH DEVELOPS FROM REMNANT FORCING
LEFTOVER FROM AN OLD FRONT...AND AS A COLD FRONT CURRENTLY MOVING
ACROSS CENTRAL GEORGIA APPROACHES THE NW PORTION HELPING TO KICK
THE HIGH AND RIDGE OFF TO THE E. THE LATEST SCATTEROMETER DATA
ALSO INDICATED THAT A WEAK PRE-FRONTAL TROUGH MAY ALREADY BE IN
THE FAR NW CORNER WHERE A SW-W WIND SHIFT IS NOTED. THE ACTUAL
COLD FRONT WILL ENTER THE NW PORTION LATE TONIGHT INTO FRI...
MOVING SLOWLY ACROSS THE N WATERS REACHING A POSITION FROM 31N70W
TO THE NW BAHAMAS BY FRI NIGHT WITH MAINLY MODERATE TO FRESH NE
WINDS AND SEAS OF 4-5 FT BEHIND IT. THE FRONT WILL GRADUALLY
DISSIPATE ACROSS THE N WATERS ON SUN WITH THE HIGH PRES BEHIND IT
TAKING CONTROL OF THE WEATHER PATTERN OVER THE REGION. MODERATE TO
FRESH NE-E WINDS WILL PREVAIL ACROSS THE FORECAST AREA SUN AND MON
WITH BUILDING SEAS OF 4-6 FT E OF THE BAHAMAS. WINDS WILL FURTHER
INCREASE TO 20-25 KT WITH SEAS OF 6-7 FT ACROSS THE SOUTH WATERS
MAINLY S OF 22N W OF 70W...INCLUDING THE WINDWARD PASSAGE ON SUN
NIGHT...AND THEN AGAIN ON MON NIGHT. THE REMNANTS OF THE FRONT
WILL BECOME AN INVERTED TROUGH WHICH WILL RETROGRADE BACK TO THE W
BEGINNING ON MON...REACHING 65W BY LATE TUE NIGHT INTO WED. THIS
TROUGHING WILL TIGHTEN THE PRES GRADIENT ON EITHER SIDE OF ITS
AXIS WITH NEARBY WINDS INCREASING TO FRESH TO STRONG LEVELS AS A
RESULT WHICH WILL BUILD FRESH SEAS TO 7-9 FT.

A 1019 MB HIGH PRES CENTER LOCATED NEAR 29N59W EXTENDS A RIDGE
WESTWARD ACROSS THE SW N ATLC OFFSHORE WATERS ALONG 26N/27N TO

PASS VERIFIED THE EXISTENCE OF MODERATE TO FRESH EASTERLY WINDS
WHERE A LOCALIZED TIGHTER PRES GRADIENT IS PRESENT.

THE HIGH PRES AND RIDGE WILL WEAKEN TONIGHT THROUGH FRI NIGHT AS
WEAK TROUGHING DISRUPTS IT WHICH DEVELOPS FROM REMNANT FORCING
LEFTOVER FROM AN OLD FRONT...AND AS A COLD FRONT CURRENTLY MOVING
ACROSS CENTRAL GEORGIA APPROACHES THE NW PORTION HELPING TO KICK
THE HIGH AND RIDGE OFF TO THE E. THE LATEST SCATTEROMETER DATA
ALSO INDICATED THAT A WEAK PRE-FRONTAL TROUGH MAY ALREADY BE IN
THE FAR NW CORNER WHERE A SW-W WIND SHIFT IS NOTED. THE ACTUAL
COLD FRONT WILL ENTER THE NW PORTION LATE TONIGHT INTO FRI...
MOVING SLOWLY ACROSS THE N WATERS REACHING A POSITION FROM 31N70W
TO THE NW BAHAMAS BY FRI NIGHT WITH MAINLY MODERATE TO FRESH NE
WINDS AND SEAS OF 4-5 FT BEHIND IT. THE FRONT WILL GRADUALLY
DISSIPATE ACROSS THE N WATERS ON SUN WITH THE HIGH PRES BEHIND IT
TAKING CONTROL OF THE WEATHER PATTERN OVER THE REGION. MODERATE TO
FRESH NE-E WINDS WILL PREVAIL ACROSS THE FORECAST AREA SUN AND MON
WITH BUILDING SEAS OF 4-6 FT E OF THE BAHAMAS. WINDS WILL FURTHER
INCREASE TO 20-25 KT WITH SEAS OF 6-7 FT ACROSS THE SOUTH WATERS
MAINLY S OF 22N W OF 70W...INCLUDING THE WINDWARD PASSAGE ON SUN
NIGHT...AND THEN AGAIN ON MON NIGHT. THE REMNANTS OF THE FRONT
WILL BECOME AN INVERTED TROUGH WHICH WILL RETROGRADE BACK TO THE W
BEGINNING ON MON...REACHING 65W BY LATE TUE NIGHT INTO WED. THIS
TROUGHING WILL TIGHTEN THE PRES GRADIENT ON EITHER SIDE OF ITS
AXIS WITH NEARBY WINDS INCREASING TO FRESH TO STRONG LEVELS AS A
RESULT WHICH WILL BUILD FRESH SEAS TO 7-9 FT.
