...GULF OF MEXICO...

MODEL PREFERENCE: GLOBAL MODEL CONSENSUS. HIGH CONFIDENCE.

A BENIGN COLD FRONT EXTENDS FROM THE STRAITS OF FLORIDA INTO THE CENTRAL GULF THEN STATIONARY FROM 25N89W TO THE TX/LA BORDER. SCATTEROMETER DATA SHOWS MODERATE TO FRESH N-NE WINDS BEHIND THE FRONT AND FRESH TO STRONG NE-LY WINDS FROM WESTERN YUCATAN INTO THE BAY OF CAMPECHE. FRONT WILL BECOME DIFFUSE ACROSS THE REGION LATER TODAY AND WINDS WILL BECOME MORE S-LY TONIGHT IN RETURN FLOW AHEAD OF THE NEXT COLD FRONT...EXPECTED TO REACH THE TX/LA COAST MON NIGHT. THE FRONT WILL SHIFT EASTWARD ACROSS NORTHERN WATERS INTO NORTHERN FLORIDA THROUGH TUE WITH THE TRAILING END OF THE FRONT EXTENDING TO NEAR 25N90W BY TUE EVENING. HIGH PRES WILL SHIFT EASTWARD N OF THE AREA TUE NIGHT THROUGH THU.


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

MODEL PREFERENCE: GLOBAL MODEL CONSENSUS. MEDIUM CONFIDENCE.

COLD FRONT IS APPROACHING THE N COAST OF CUBA AND SCATTEROMETER DATA SHOWS STRONG NE WINDS S OF CUBA BETWEEN 77W-81W AND FRESH TO STRONG WINDS ELSEWHERE IN THE NW CARIBBEAN. ANOTHER AREA OF STRONG TO NEAR-GALE WARNING E-NE WINDS IS DEPICTED NEAR THE COAST OF COLOMBIA BETWEEN 71W-77W. GFS MODEL GUIDANCE INDICATES THIS AREA EXPECTED TO EXPERIENCE GALE FORCE WINDS AT CURRENT TIME BETWEEN 06Z-12Z BUT ASCAT PASS AT 03Z DOES NOT HAVE WIND BARBS GREATER THAN 30 KT...SO WILL NOT PULL TRIGGER ON A GALE WARNING FOR THIS MORNING AND KEEP A GALE WARNING IN EFFECT FOR LATE TONIGHT WHEN GFS IS MORE BULLISH THAN PRESENT. STRONG HIGH PRES N OF FRONT BRIDGING ACROSS THE APPROACHING BOUNDARY WILL INDUCE TIGHT PRES GRADIENT ACROSS THE CARIB ALONG AN OLD FRONTAL BOUNDARY. MODELS SHOW WELL DEFINED SHEAR AXIS NEXT FEW DAYS ACROSS THE N CENTRAL AND NW CARIB...INDICATING A BOUNDARY WILL PERSIST. THE FRONT NEAR CUBA WILL MOVE INTO YUCATAN CHANNEL THIS MORNING AND STALL ALONG 22N LATER TODAY WHILE STRONG HIGH PRESSURE SHIFTS E TO MID ATLC COAST. WINDS WILL FRESHEN THROUGH WINDWARD PASSAGE TODAY AS RIDGE INTENSIFIES WITH SEAS BUILDING TO 8 FT. EXPECT FRESH TO STRONG TRADES TO PREVAIL ACROSS MOST OF THE CENTRAL CARIBBEAN THROUGH THU WITH MODERATE TO FRESH E WINDS EXPECTED ELSEWHERE... INCLUDING THE TROPICAL N ATLC.


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

MODEL PREFERENCE: GLOBAL MODEL CONSENSUS. MEDIUM CONFIDENCE.

OLD STATIONARY FRONT NOW DEPICTED AS SURFACE TROUGH ON LATEST ANALYSIS. REINFORCING COLD FRONT QUICKLY PUSHING SE ACROSS THE REGION WITH LITTLE OR NO SIG WEATHER EFFECTS. SCATTEROMETER DATA SHOWS FRESH N-NW WINDS BEHIND THE FRONT AND FRESH TO STRONG WLY WINDS N OF 28N ASSOCIATED WITH THE FRONT BETWEEN 67W-72W. FRONT WILL REACH FROM 26N65W TO CENTRAL CUBA LATER TODAY...STALL FROM 25N65W TO CENTRAL CUBA MON AND THEN LIFT N AND BECOME DIFFUSE MON NIGHT AND TUE AS NEXT FRONT APPROACHES THE E COAST. PRES GRADIENT BETWEEN A STRONG HIGH BEHIND FRONT AND THE STALLING BOUNDARY WILL PRODUCE AN AREA OF STRONG NE WINDS N OF FRONT TONIGHT THROUGH MON NIGHT. NE WIND WAVES COMBINED WITH NW SWELL WILL BUILD SEAS TO 8-12 FT BY MON AFTERNOON. THIS PATTERN HAS POTENTIAL FOR NE WINDS THROUGH THE BAHAMAS TO BUILD SEAS TO 7-8 FT THROUGH SE PASSAGES BY MON MORNING.
