MARINE WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
102 PM EDT SAT AUG 1 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.

...GULF OF MEXICO...

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

A WEAK COLD FRONT WAS ANALYZED AT 1200 UTC FROM LOW PRES NEAR
APALACHICOLA BAY TO 29N85W THEN W TO NEAR CORPUS CHRISTI TEXAS.
THIS FRONT IS FORECAST TO MEANDER OVER THE N CENTRAL GULF COASTAL
WATERS AS A STATIONARY FRONT THROUGH THE WEEKEND BEFORE
DISSIPATING...WITH THE REMNANTS LIFTING N OF THE AREA LATE MON.
THE MID-LEVEL ENERGY ASSOCIATED WITH THIS SYSTEM IS BEING
INFLUENCED NORTHWARD BY THE LEADING EDGE OF A NORTHERN STREAM
TROUGH. THE BOUNDARY HAS PUSHED EASTWARD OVER THE NE
GULF...INCREASING THE PRESSURE GRADIENT BETWEEN IT AND THE RIDGE
TO ITS S. THIS HAS ALLOW SW WINDS TO INCREASE TO 20-25 KT AHEAD
OF THE FRONT N OF 28N ACCORDING TO THE 0936 UTC RAPIDSCAT PASS AND
BUOY 42036 WHICH SAW SEAS IN THE 7-8 FT RANGE FROM 08Z-12Z. THESE
WINDS WILL SLOWLY DIMINISH OVERNIGHT AS THE NORTHERN STREAM TROUGH
LOSES ITS GRIP ON THE ENERGY OVER THE NE GULF.

A TROUGH WILL DEVELOP EACH NIGHT OVER THE YUCATAN PENINSULA AND
MOVE NW DURING LATE NIGHT THROUGH EARLY MORNING HOURS BEFORE
DISSIPATING OVER THE SW GULF DURING LATE MORNING HOURS. WINDS WILL
INCREASE TO A MODERATE TO FRESH BREEZE BEHIND THE TROUGH IN THE
LATE NIGHT AND EARLY MORNING HOURS...WITH WINDS BECOMING MORE
CONSISTENT A FRESH BREEZE BEGINNING MON MORNING BEHIND A TROPICAL
WAVE AND CONTINUING INTO WED AS RIDGING BUILDS TO THE N.


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

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

ATLC RIDGING COMBINED WITH LOW PRESSURE OVER NW COLOMBIA WILL
CONTINUE TO SUPPORT FRESH TO STRONG TRADE WINDS OVER THE SOUTH-
CENTRAL CARIBBEAN. THE AREA OF FRESH TO STRONG TRADES WILL GROW
AS THE RIDGE BUILDS W OVER THE SW N ATLC OVER THE WEEKEND. WINDS
WITHIN 90 NM OF THE COAST OF COLOMBIA WILL INCREASE TO GALE FORCE
OVERNIGHT TONIGHT AND SUN NIGHT IN RESPONSE TO THE BUILDING RIDGE
TO THE N...AND THEN BACK OFF TO A DIURNAL MAX OF 30 KT BY MON. AT
THAT TIME...THE AREA OF FRESH TO STRONG WINDS WILL EXPAND
EASTWARD IN RESPONSE TO THE RIDGE SHIFTING E OVER THE CENTRAL
ATLC.

OTHERWISE...CONDITIONS SHOULD BE RELATIVELY QUIET ASIDE FROM AN
INCREASED CHANCE OF PRECIPITATION AS TROPICAL WAVES PASS THROUGH
THE REGION. A TROPICAL WAVE NEAR 83W WILL MOVE ACROSS THE WESTERN
CARIBBEAN THROUGH SUN NIGHT. ANOTHER TROPICAL WAVE HAS JUST MOVED
INTO THE TROPICAL N ATLC W OF 55W...WILL ENTER THE EASTERN
CARIBBEAN LATE SUN AND REACH THE WESTERN CARIBBEAN BY WED. A
THIRD WAVE IS EXPECTED IN THE TROPICAL N ATLC WED. WINDS MAY
BRIEFLY BUILD TO A FRESH TO STRONG BREEZE IN THE GULF OF HONDURAS
MON INTO EARLY TUE BEHIND A TROPICAL WAVE.


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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL
FORECAST FOR WINDS. LATEST MWW3 AND NWPS BLENDED WITH
PREVIOUS/OFFICIAL FORECAST FOR WAVE PARAMETERS. HIGH CONFIDENCE.

SHOWERS AND THUNDERSTORMS ARE WIDESPREAD OVER THE BAHAMAS AND OFF
THE FLORIDA COAST TODAY. THIS AREA IS ON THE LEADING EDGE OF A
LOW-LEVEL TROUGH OVER NW WATERS AND UNDER DIFFLUENCE ALOFT
BETWEEN AN UPPER LOW CENTERED NEAR 24N74W AND A RIDGE AXIS FROM
THE TEXAS BIG BEND TO SAVANNAH GEORGIA. SHOWERS AND THUNDERSTORMS
ARE EXPECTED TO CONTINUE HERE THROUGH THE WEEKEND BEFORE THE
PATTERN BREAKS DOWN. SW WINDS ARE 20-25 KT N OF 30N BETWEEN
76W-80W ACCORDING TO THE 0936 UTC RAPIDSCAT PASS...WITH SHIP OXKO2
REPORTING 8 FT SEAS NEAR 31N78W AT 1100 UTC. THE WINDS SHOULD
DIMINISH BELOW THE ADVISORY CRITERIA OF 20-25 KT BY MON MORNING AS
THE TROUGHING SLACKENS HERE. AS THE TROUGHING DIMINISHES...THE
RIDGE AXIS THAT CURRENTLY LIES FROM 29N65W TO THE STRAITS OF
FLORIDA WILL SLOWLY LIFT NORTHWARD. THE RIDGE SHOULD REACH FROM 30N65W
TO HOBE SOUND SUN AND FROM 31N65W TO CAPE CANAVERAL TUE BEFORE
STALLING. FRESH TRADES WILL DEVELOP ALONG THE N COAST OF
HISPANIOLA EACH NIGHT THROUGH WED NIGHT.

...GULF OF MEXICO...

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL

FORECAST FOR WAVE PARAMETERS. HIGH CONFIDENCE.

A SURFACE TROUGH EXTENDS FROM THE FLORIDA PANHANDLE ACROSS THE
NORTH GULF WATERS TO NEAR 28N91W GENERATING SCATTERED SHOWERS AND
TSTMS. GUSTY WINDS CAN BE EXPECTED WITH THIS ACTIVITY. THE TROUGH
IS FORECAST TO SINK SOUTHWARD INTO THE CENTRAL WATERS TODAY...THEN
WILL REMAIN NEARLY STATIONARY ON SAT AND LIFT NORTHWARD ON SUN.
MARINE GUIDANCE SUGGESTS INCREASING SOUTHWESTERLY WINDS OF 20-25
KT ON THE SOUTH SIDE OF THE TROUGH BY SAT...ESPECIALLY OVER THE
NE GULF WATERS. EXPECT ALSO BUILDING SEAS OF 6-7 FT WITH THESE
WIND SPEEDS.

AN INVERTED THERMAL TROUGH WILL DEVELOP EACH NIGHT OVER THE YUCATAN
PENINSULA AND MOVE NW DURING LATE NIGHT THROUGH THE EARLY MORNING
HOURS BEFORE DISSIPATING OVER THE SW GULF DURING THE LATE MORNING
HOURS. MAINLY FRESH N-NE WINDS AND SEAS OF 4-5 FT WILL BE ASSOCIATED
WITH THIS TROUGH. WINDS MAY BRIEFLY INCREASE TO 25 KT BY MON NIGHT.

THE REMAINDER OF THE GULF REGION IS UNDER THE INFLUENCE OF A WEAK
RIDGE PRODUCING MAINLY GENTLE TO MODERATE WINDS AND SEAS GENERALLY
UNDER 4 FT. THE RIDGE IS EXPECTED TO BUILD BACK ACROSS THE AREA
BY EARLY NEXT WEEK.

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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL

THE 0200 UTC ASCAT PASS SHOWED FRESH TO STRONG WINDS OF 20-25 KT
ACROSS THE SOUTH-CENTRAL CARIBBEAN MAINLY FROM 11N-14N BETWEEN
73W-78W. THE SAME ASCAT PASS SHOWED A LARGE AREA OF MOSTLY FRESH NE
WINDS OVER MUCH OF THE CENTRAL CARIBBEAN S OF 16N. FRESH WINDS ARE
ALSO NOTED PER SCATTEROMETER DATA ACROSS THE GULF OF HONDURAS.

MAINLY FRESH TRADES WILL CONTINUE OVER THE CENTRAL CARIBBEAN
THROUGH THE PERIOD WITH POCKETS OF STRONG NE TRADES NEAR THE
COAST OF COLOMBIA THROUGH SAT. BY SAT NIGHT INTO SUN...EXPECT
TRADE WINDS OF 25-30 KT ACROSS THE SOUTH CENTRAL CARIBBEAN AND
BUILDING SEAS OF 10-12 FT. THESE MARINE CONDITIONS ARE EXPECTED
TO PERSIST THROUGH THE REMAINDER OF THE FORECAST PERIOD AS HIGH
PRES BUILDS BACK N OF AREA.

A TROPICAL WAVE NEAR 75W WILL MOVE ACROSS THE REMAINDER OF THE
CENTRAL CARIBBEAN TODAY...THEN ACROSS THE WESTERN CARIBBEAN FRI
NIGHT THROUGH SUN...REACHING THE YUCATAN PENINSULA SUN NIGHT.
ANOTHER TROPICAL WAVE CURRENTLY OVER THE CENTRAL TROPICAL ATLC
WILL APPROACH 55W LATE ON SAT...AND MOVE ACROSS THE EASTERN
CARIBBEAN ON MON.

LOOKING AHEAD...A BROAD LOW PRESSURE LOCATED A FEW HUNDRED MILES
SW OF THE CAPE VERDE ISLANDS CONTINUES TO PRODUCE DISORGANIZED
SHOWERS AND TSTMS AND HAS THE POTENTIAL FOR SOME SLOW DEVELOPMENT
INTO EARLY NEXT WEEK AS IT MOVES IN A GENERAL WESTWARD TRACK.

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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL

THE ATLANTIC RIDGE IS BUILDING BACK ACROSS THE SW N ATLC AS THE
LOW PRES WITH THE ASSOCIATED TRAILING TROUGH PREVIOUSLY LOCATED
OVER THE NW WATERS MOVES N OF AREA. THE RIDGE AXIS IS NOW ALONG
29N. PRES GRADIENT BETWEEN THE RIDGE AND A COLD FRONT APPROACHING
THE ATLANTIC SEA BOARD WILL PRODUCE AN AREA OF SOUTHWESTERLY WINDS
IN THE 20-25 KT RANGE ACROSS PARTS OF THE FORECAST ZONES AMZ111
AND AMZ113 THROUGH SUN. THE RIDGE WILL REMAIN IN PLACE THROUGHOUT
THE REMAINDER OF THE FORECAST PERIOD.

SCATTEROMETER DATA INDICATE FRESH TO STRONG WINDS OVER THE S
WATERS JUST N OF HISPANIOLA...INCLUDING THE WINDWARD PASSAGE.
FRESH TRADES WILL DEVELOP ALONG THE N COAST OF HISPANIOLA EACH
NIGHT THROUGH TUE NIGHT.

64W...AND THE SW N ATLANTIC INCLUDING THE BAHAMAS.

...GULF OF MEXICO...

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL
FORECAST FOR WINDS. LATEST MWW3 BLENDED WITH PREVIOUS/OFFICIAL
FORECAST FOR WAVE PARAMETERS. HIGH CONFIDENCE.

A SURFACE TROUGH EXTENDS FROM THE FLORIDA PANHANDLE ACROSS THE
NORTH GULF WATERS TO NEAR 28N91W GENERATING SCATTERED SHOWERS AND
TSTMS. GUSTY WINDS CAN BE EXPECTED WITH THIS ACTIVITY. THE TROUGH
IS FORECAST TO SINK SOUTHWARD INTO THE CENTRAL WATERS TODAY...THEN
WILL REMAIN NEARLY STATIONARY ON SAT AND LIFT NORTHWARD ON SUN.
MARINE GUIDANCE SUGGESTS INCREASING SOUTHWESTERLY WINDS OF 20-25
KT ON THE SOUTH SIDE OF THE TROUGH BY SAT...ESPECIALLY OVER THE
NE GULF WATERS. EXPECT ALSO BUILDING SEAS OF 6-7 FT WITH THESE
WIND SPEEDS.

AN INVERTED THERMAL TROUGH WILL DEVELOP EACH NIGHT OVER THE YUCATAN
PENINSULA AND MOVE NW DURING LATE NIGHT THROUGH THE EARLY MORNING
HOURS BEFORE DISSIPATING OVER THE SW GULF DURING THE LATE MORNING
HOURS. MAINLY FRESH N-NE WINDS AND SEAS OF 4-5 FT WILL BE ASSOCIATED
WITH THIS TROUGH. WINDS MAY BRIEFLY INCREASE TO 25 KT BY MON NIGHT.

THE REMAINDER OF THE GULF REGION IS UNDER THE INFLUENCE OF A WEAK
RIDGE PRODUCING MAINLY GENTLE TO MODERATE WINDS AND SEAS GENERALLY
UNDER 4 FT. THE RIDGE IS EXPECTED TO BUILD BACK ACROSS THE AREA
BY EARLY NEXT WEEK.

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

THE 0200 UTC ASCAT PASS SHOWED FRESH TO STRONG WINDS OF 20-25 KT
ACROSS THE SOUTH-CENTRAL CARIBBEAN MAINLY FROM 11N-14N BETWEEN
73W-78W. THE SAME ASCAT PASS SHOWED A LARGE AREA OF MOSTLY FRESH NE
WINDS OVER MUCH OF THE CENTRAL CARIBBEAN S OF 16N. FRESH WINDS ARE
ALSO NOTED PER SCATTEROMETER DATA ACROSS THE GULF OF HONDURAS.

MAINLY FRESH TRADES WILL CONTINUE OVER THE CENTRAL CARIBBEAN
THROUGH THE PERIOD WITH POCKETS OF STRONG NE TRADES NEAR THE
COAST OF COLOMBIA THROUGH SAT. BY SAT NIGHT INTO SUN...EXPECT
TRADE WINDS OF 25-30 KT ACROSS THE SOUTH CENTRAL CARIBBEAN AND
BUILDING SEAS OF 10-12 FT. THESE MARINE CONDITIONS ARE EXPECTED
TO PERSIST THROUGH THE REMAINDER OF THE FORECAST PERIOD AS HIGH
PRES BUILDS BACK N OF AREA.

A TROPICAL WAVE NEAR 75W WILL MOVE ACROSS THE REMAINDER OF THE
CENTRAL CARIBBEAN TODAY...THEN ACROSS THE WESTERN CARIBBEAN FRI
NIGHT THROUGH SUN...REACHING THE YUCATAN PENINSULA SUN NIGHT.
ANOTHER TROPICAL WAVE CURRENTLY OVER THE CENTRAL TROPICAL ATLC
WILL APPROACH 55W LATE ON SAT...AND MOVE ACROSS THE EASTERN
CARIBBEAN ON MON.

LOOKING AHEAD...A BROAD LOW PRESSURE LOCATED A FEW HUNDRED MILES
SW OF THE CAPE VERDE ISLANDS CONTINUES TO PRODUCE DISORGANIZED
SHOWERS AND TSTMS AND HAS THE POTENTIAL FOR SOME SLOW DEVELOPMENT
INTO EARLY NEXT WEEK AS IT MOVES IN A GENERAL WESTWARD TRACK.

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

MODEL PREFERENCE: LATEST GFS BLENDED WITH PREVIOUS/OFFICIAL
FORECAST FOR WINDS. LATEST MWW3 BLENDED WITH PREVIOUS/OFFICIAL
FORECAST FOR WAVE PARAMETERS. HIGH CONFIDENCE.

THE ATLANTIC RIDGE IS BUILDING BACK ACROSS THE SW N ATLC AS THE
LOW PRES WITH THE ASSOCIATED TRAILING TROUGH PREVIOUSLY LOCATED
OVER THE NW WATERS MOVES N OF AREA. THE RIDGE AXIS IS NOW ALONG
29N. PRES GRADIENT BETWEEN THE RIDGE AND A COLD FRONT APPROACHING
THE ATLANTIC SEA BOARD WILL PRODUCE AN AREA OF SOUTHWESTERLY WINDS
IN THE 20-25 KT RANGE ACROSS PARTS OF THE FORECAST ZONES AMZ111
AND AMZ113 THROUGH SUN. THE RIDGE WILL REMAIN IN PLACE THROUGHOUT
THE REMAINDER OF THE FORECAST PERIOD.
