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: GLOBAL MODEL CONSENSUS. HIGH CONFIDENCE.

HIGH PRESSURE WILL REMAIN NEARLY STATIONARY IN THE E CENTRAL GULF
THROUGH THE NEXT SEVERAL DAYS...WHILE WEAK SURFACE TROUGHING WILL
PREVAIL ACROSS THE NW AND N CENTRAL GULF. THE TROUGH WILL HELP TO
SUPPORT CONVECTION EACH DAY. A THERMAL TROUGH WILL DEVELOP OVER
THE YUCATAN PENINSULA DURING EACH EVENING...PUSHING OFFSHORE AND
DISSIPATING IN THE SW GULF EACH NIGHT. MAINLY GENTLE WINDS WILL
PREVAIL EXCEPT MODERATE WITHIN 60-90 NM OF SHORE W OF 90W...AND
PULSATING TO 20 KT NW OF THE YUCATAN PENINSULA AHEAD OF THE
TROUGHING EACH NIGHT. SEAS WILL BE 2 FT OR LESS THROUGH THE END OF
THE WEEK...THEN GRADUALLY BUILDING TO 3-5 FT ACROSS THE SW HALF OF
THE GULF THIS WEEKEND INTO EARLY NEXT WEEK AS THE SOUTHEASTERLY
FETCH AREA LENGTHENS SOMEWHAT.

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

MODEL PREFERENCE: GLOBAL MODEL CONSENSUS. HIGH CONFIDENCE.

HIGH PRESSURE IN THE CENTRAL ATLC COMBINED WITH LOW PRESSURE OVER

ACROSS THE CENTRAL CARIBBEAN...INCREASING TO MINIMAL GALE FORCE
IN THE GULF OF HONDURAS THIS EVENING INTO EARLY FRI. A STRONG
TROPICAL WAVE WILL APPROACH THE EASTERN CARIBBEAN THIS WEEKEND
BRINGING A SURGE OF FRESH TO STRONG EASTERLY FLOW WITH IT. WINDS
WILL PULSATE TO FRESH TO STRONG IN THE GULF OF HONDURAS DURING THE
OVERNIGHT HOURS STARTING FRI NIGHT DUE TO A LOCAL DIURNALLY TIGHT
PRESSURE GRADIENT. MODERATE TO FRESH TRADES WILL PREVAIL ELSEWHERE.
SEAS WILL BE MAINLY 8-12 FT IN THE CENTRAL CARIBBEAN AND 4-7 FT
ELSEWHERE...EXCEPT 3-5 FT IN THE NW CARIBBEAN.

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

MODEL PREFERENCE: GLOBAL MODEL CONSENSUS. HIGH CONFIDENCE.

SURFACE TROUGHING MAY MANAGE TO OCCASIONALLY SNEAK OFF OF THE
SOUTHEAST UNITED STATES COAST INTO THE COASTAL WATERS EACH DAY.
OTHERWISE HIGH PRESSURE RIDGING WILL CONTINUE TO DOMINATE THE
BASIN FOR THE FORESEEABLE FUTURE. MAINLY MODERATE RETURN FLOW WILL
PREVAIL ACROSS THE BASIN AROUND THE RIDGING...PULSATING TO FRESH
TO STRONG OFFSHORE OF HISPANIOLA FROM AROUND 06 UTC TO 18 UTC EACH
DAY...STARTING LATER TODAY. SEAS WILL BE MAINLY 3-5 FT...BUILDING
