MARINE WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
403 AM EDT SUN MAR 29 2015

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.

PRODUCT RELEASED EARLY FOR COMPUTER MAINTENANCE

...GULF OF MEXICO...

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS OFFICIAL
FORECAST. TAFB NWPS USED FOR WAVE PARAMETERS. HIGH CONFIDENCE.

FRESH SOUTHERLY RETURN FLOW IS NOTED OVER THE NW GULF BETWEEN WEAK
HIGH PRES OVER THE N CENTRAL GULF AND A TROUGH OVER TEXAS. CMAN
AND SHIP OBSERVATIONS INDICATE FRESH NORTHERLY WINDS ACROSS THE
FLORIDA KEYS WITH SEAS TO 7 FT...WITH FRESH TO EVEN STRONG NE
WINDS NEAR THE YUCATAN CHANNEL SOUTH OF THE HIGH PRES. FRESH NE
WINDS ARE ALSO LIKELY OFF NW YUCATAN THIS MORNING. ELSEWHERE
GENERALLY LIGHT TO MODERATE BREEZES AND 2 TO 4 FT PREVAIL.

THERE REMAINS GENERAL AGREEMENT AMONG GLOBAL MODELS SHOWING
LITTLE CHANGE THROUGH THE MIDDLE OF THE WEEK. AN UPPER DISTURBANCE
WILL APPROACH THE NW GULF TUE INTO WED...INCREASING THE CHANCES
FOR SHOWERS AND A FEW THUNDERSTORMS BUT HAVE LITTLE IMPACT ON
WINDS OR SEAS. THE LOCAL EVENING TROUGHING OVER THE NW YUCATAN WILL
DEVELOP EACH NIGHT...ENHANCING OVERNIGHT WINDS OFF NW YUCATAN AND
IN THE EASTERN AND CENTRAL BAY OF CAMPECHE.

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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS OFFICIAL
FORECAST. TAFB NWPS USED FOR WAVE PARAMETERS. HIGH CONFIDENCE.

A DISSIPATING STATIONARY FRONT REACHES FROM SE CUBA TO EASTERN
HONDURAS. A 03 UTC ASCAT SATELLITE PASS ALONG WITH CONCURRENT
REPORTS FROM BUOY 42055 INDICATED FRESH TO STRONG WINDS ON THE LEE
SIDE OF CUBA TO THE NORTH OF THE DYING FRONT...AND TO THE SOUTH OF
HIGH PRES MOVING FROM THE N CENTRAL GULF OF MEXICO TO THE WESTERN
ATLC. FARTHER TO THE SOUTH...BUOYS AND SCATTEROMETER DATA INDICATE
FRESH TRADES OVER MUCH OF THE SE AND S CENTRAL CARIBBEAN. WINDS
ARE LIKELY PULSING TO 25 KT OFF COLOMBIA. FARTHER EAST...AN
ALTIMETER SATELLITE PASS ALONG WITH BUOY OBSERVATIONS SHOW SEAS OF
8 TO 9 FT PERSISTING IN THE TROPICAL N ATLC WATERS EAST OF THE
LEEWARD AND WINDWARD ISLANDS LIKELY IN NE SWELL.

GLOBAL MODELS INDICATE PERIODS OF AT LEAST 20 KT NE FLOW REPEATING
ON THE LEE SIDE OF CUBA OVER THE NW CARIBBEAN IN RESPONSE TO THE
HIGH PRES N OF THE AREA THROUGH EARLY MONDAY. TRADE WINDS WILL
ALSO CONTINUE TO PULSE TO 25 KT OFF COLOMBIA FOR THE NEXT SEVERAL
NIGHTS...AND TO 20 KT OFF VENEZUELA AND THE ABC ISLANDS. BOTH MWW3
AND ECWAVE GUIDANCE SUGGESTS THE SWELL EAST OF THE ISLANDS WILL
SUBSIDE BELOW 8 FT THROUGH LATE SUNDAY. THIS WILL LEAVE MODERATE
TO FRESH TRADE WINDS WITH 5 TO 6 FT SEAS OVER THE TROPICAL N ATLC
THROUGH MID WEEK.

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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS OFFICIAL
FORECAST. TAFB NWPS USED FOR WAVE PARAMETERS. MEDIUM CONFIDENCE.

A COLD FRONT REACHES FROM BERMUDA TO EASTERN CUBA. A FEW SHOWERS
AND THUNDERSTORMS CONTINUE ALONG THE FRONT. THE NORTHERN PORTION
OF THE FRONT WILL CONTINUE EAST WHILE THE SOUTHERN PORTION STALLS
AND DISSIPATES THROUGH EARLY NEXT WEEK S OF 24N. A SUPPORTING
UPPER DISTURBANCE IS MOVING OFF THE CAROLINA COAST INTO THE
WESTERN ATLC...PROVIDING A REINFORCMENT TO THE FRONT. THIS
INCREASE WESTERLY FLOW N OF THE AREA EARLIER IN THE EVENING...AND
IN TURN ALLOWED SEAS TO BUILD TO 10 AND 11 FT AS NOTED IN BUOYS
ALONG 31.5N...BUT A RECENT ALTIMETER SATELLITE PASS INDICATED SEAS
GREATER THAN 8 FT WERE LIKELY RESTRICTED TO THE WATERS N OF 30N E
OF 75W SO FAR. NW SWELL FROM THE REINFORCED WINDS WILL REACH AS
FAR S AS 27N W OF 75W THROUGH LATE TODAY. A SECOND REINFORCING
IMPULSE WILL PUSH OFF THE CAROLINAS LATE MON AND TUE. MOST THE
IMPACT OF THIS WILL BE CONSTRAINED TO N OF 31N HOWEVER. RIDGING
WILL BUILD ACROSS THE WATERS ALONG ROUGHLY 27N...MAINTAININGRELATIVELY
MILD MARINE CONDITIONS THROUGH MID WEEK. NO MAJOR DIFFERENCES IN
MODEL OUTPUT ARE NOTED.

HIGH PRES IS BUILDING OVER THE WESTERN GULF OF MEXICO BEHIND A
STRONG COLD FRONT THAT SWEPT TO THE SOUTHEAST OF THE AREA LAST

FAR NE GULF WITH 6 TO 8 FT SEAS OVER MUCH OF THE EASTERN GULF. THE
HIGH PRES WILL SHIFT NE TODAY AND MERGE WITH A BUILDING RIDGE OVER
THE EASTERN UNITED STATES ALLOWING MODERATE TO FRESH RETURN FLOW
ACROSS THE NW GULF. THIS SOUTHERLY FLOW WILL DIMINISH THROUGH
MONDAY AS LOW PRES OVER THE PLAINS LIFTS NE. THE BUILDING RIDGE
OVER THE EASTERN UNITED STATES WILL ALSO SUPPORT AN AREA OF FRESH
TO STRONG NE WINDS NEAR THE YUCATAN CHANNEL LATE SUNDAY. A TROUGH
OFF NW YUCATAN WILL DEVELOP EACH EVENING THROUGH AT LEAST MONDAY...BRINGING
A BRIEF PERIOD OF FRESH TO STRONG NE WINDS TO THAT AREA. OTHERWISE
MODELS ARE IN GOOD AGREEMENT SHOWING FAIRLY MINIMAL WINDS AND SEAS

FRESH TO STRONG NE WINDS IN THE LEE OF CUBA LATE SUNDAY NIGHT
ALONG THE FRONT. OTHERWISE...MODELS ARE IN GOOD AGREEMENT SHOWING RELATIVE
MODEST WINDS AND SEAS WILL PERSIST ACROSS THE BASIN THROUGH THE
MIDDLE OF NEXT WEEK. BUOYS IN THE TROPICAL ATLC WATERS ARE
SHOWING 8 TO 9 FT SEAS IN NE SWELL. SEAS ARE 9 FT AT BUOY 41300
200 NM E OF GUADELOUPE...A COUPLE OF FEET HIGHER THAN THE MWW3 AND
