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: GFS/OFFICIAL BLEND WITH GOOD CONFIDENCE.

WEAK HIGH PRES WILL PERSIST OVER THE EASTERN GULF THROUGH WED. 
EXPECT GENTLE TO MODERATE E-SE WINDS ACROSS MOST OF THE REGION 
THROUGH LATE WED...BECOMING LIGHT AND VARIABLE THU AND FRI. SEAS 
WILL BE 3 FT OR LESS THROUGH FRI...EXCEPT W OF 95W AND SW GULF 
WHERE SEAS MAY REACH 3-4 FT AT TIMES.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC...                    
MODEL PREFERENCE: GFS/OFFICIAL BLEND WITH GOOD CONFIDENCE.

PERSISTENT HIGH PRES RIDGE IN WEST-CENTRAL ATLC AND STATIONARY 
LOW PRES OVER NORTHERN SOUTH AMERICA WILL MAINTAIN MODERATE PRES 
GRADIENT ACROSS THE REGION WITH 20-25 KT E WINDS EXPECTED TO
CONTINUE IN THE CENTRAL CARIBBEAN FOR THE FORESEEABLE FUTURE.
REMNANTS OF DORIAN NOW CLASSIFIED AS STRONG TROPICAL WAVE WILL
BRIEFLY DISRUPT THE PRES GRADIENT AS IT PASSES N OF THE GREATER
ANTILLES THROUGH TUE...ALLOWING WINDS TO DIMINISH SLIGHTLY IN THE
CARIBBEAN.

...SW N ATLANTIC W OF 55W INCLUDING THE BAHAMAS...               
MODEL PREFERENCE: GFS/OFFICIAL BLEND WITH GOOD CONFIDENCE.

A PERSISTENT HIGH PRES RIDGE IN WEST-CENTRAL ATLC AND REMNANTS OF
DORIAN...NOW CLASSIFIED AS STRONG TROPICAL WAVE ALONG 65W/66W MOVING
WESTWARD INTO AND THROUGH THE S BAHAMAS WILL BE THE MAIN DRIVING
FORCE FOR MARINE WEATHER CONDITIONS ACROSS THE AREA. TIGHT PRES
GRADIENT BETWEEN THESE TWO FEATURES WILL PRODUCE A SWATH OF HIGHER
WINDS AND SEAS BETWEEN 20N AND 26N THROUGH WED. DESPITE A BETTER
SATELLITE SIGNATURE THIS MORNING...ALL MODEL GUIDANCE INDICATES
THE WAVE WILL WEAKEN AS IT APPROACHES FLORIDA THROUGH WED. A RIDGE
AXIS IS EXPECTED TO REMAIN ROUGHLY ALONG 29N THROUGH THE FORECAST
PERIOD.
