NWS NATIONAL HURRICANE CENTER MIAMI FL
145 PM EDT SUN JUN 23 2013

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: BLEND OF LATEST OFFICIAL FORECAST WITH GFS 
WITH HIGH CONFIDENCE.

A WEAK TROUGH IS IN THE NORTHERN GULF WHILE A BROAD RIDGE
DOMINATES THE REMAINDER OF THE GULF. A WEAKENING TROPICAL WAVE
ALONG 86W WILL MOVE ACROSS THE YUCATAN PENINSULA TODAY INTO THE SW
GULF TONIGHT AND MON. A RIDGE ALONG 27N WILL DRIFT NORTH AND
SOUTH ACROSS THE NORTHERN GULF AND MAINTAIN GENTLE TO MODERATE
E-SE WINDS ACROSS THE GULF THROUGH THU.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC...                      
MODEL PREFERENCE: BLEND OF LATEST OFFICIAL FORECAST WITH GFS AND 
ECMWF WITH HIGH CONFIDENCE.

FRESH TO STRONG TRADES PERSIST ACROSS MOST OF BASIN WITH HIGHEST 
WINDS CONTINUING IN THE CENTRAL CARIBBEAN BETWEEN 72W AND 78W. 
THIS WEATHER PATTERN IS EXPECTED TO PERSIST THROUGH AT LEAST TUE
AS HIGH PRES REMAINS CENTERED NEAR BERMUDA. THE HIGH PRES WILL
SLIGHTLY WEAKEN WED AND THU...ALLOWING THE AERIAL EXTENT AND
STRENGTH OF THE TRADES TO DECREASE. EXPECT SEAS OF 8 TO 10 FT
ACROSS THE SOUTH- CENTRAL CARIBBEAN IN ASSOCIATION WITH THE
TRADES. A TROPICAL WAVE ALONG 56W ENTERING THE TROPICAL N ATLC
WATERS WILL MOVE INTO EASTERN CARIBBEAN EARLY MON AND REACH THE
CENTRAL CARIBBEAN TUE. A THIRD BETTER-DEFINED TROPICAL WAVE ALONG
43W WILL CROSS THE TROPICAL N ATLC MON NIGHT AND TUE MOVING INTO
THE EASTERN CARIBBEAN WED. MARINE GUIDANCE SUGGESTS THAT AN AREA
OF 20-25 KT WINDS...WITH HIGHER GUSTS AND SEAS OF UP TO 10 FT WILL
ACCOMPANY THE WAVE.

...SW N ATLANTIC W OF 55W INCLUDING THE BAHAMAS...               
     
MODEL PREFERENCE: BLEND OF LATEST OFFICIAL FORECAST WITH GFS AND 
WITH HIGH CONFIDENCE.

HIGH PRESSURE CENTERED NEAR BERMUDA WILL EXTEND A RIDGE ACROSS 
THE SW N ATLC DURING THE FORECAST PERIOD...PRODUCING MODERATE TO 
FRESH WINDS IN SOUTHERN WATERS AND GENTLE TO MODERATE E-SE WINDS 
IN NORTHERN WATERS. TROPICAL WAVES PREVIOUSLY MENTIONED PASSING 
THROUGH THE TROPICAL N ATLC AND CARIBBEAN WILL REMAIN SOUTH OF 
THE REGION WITH LITTLE OR NO EFFECT EXPECTED IN SOUTHERN WATERS.
