MARINE WEATHER DISCUSSION FOR GULF OF MEXICO...CARIBBEAN SEA AND 
SOUTHWEST NORTH ATLC S OF 31N W OF 55W

GULF OF MEXICO...
STRONG HIGH PRES CENTERED OVER THE MIDDLE ATLC STATES EXTENDS A 
RIDGE ACROSS THE GULF REGION. THE COMBINATION OF THE HIGH AND 
LOW PRES OVER TEXAS AND NE MEXICO WILL TIGHT THE PRES GRADIENT 
AND PRODUCE INCREASING WINDS AND SEAS ACROSS THE WESTERN AND 
MIDDLE GULF THIS AFTERNOON AND SPREAD E ACROSS THE REMAINDER OF 
THE AREA TONIGHT THROUGH THU. THESE CONDITIONS SHOULD THEN 
SUBSIDE BEGINNING LATE THU THROUGH FRI AS HIGH PRES SETTLES IN 
OVER THE NE GULF. EXPECT SELY WINDS IN THE 20 TO 25 KT RANGE 
ACROSS MUCH OF THE GULF THROUGH THU WITH BUILDING SEAS TO AROUND 
9 FT. THE YUCATAN DIURNAL SEABREEZE WILL CONTINUE TO FLARE TO 
20-25 KT WITHIN 90-120 NM OF THE COAST DURING LATE AFTERNOON AND 
EARLY NIGHT THROUGH THE FORECAST PERIOD. A MUCH EARLIER WINDSAT 
PASS CONFIRMED THE FRESH TO STRONG BREEZE NEAR THE YUCATAN 
PENINSULA.

SW N ATLANTIC S OF 31N W OF 55W...
A COLD FRONT STRETCHING FROM 30N65W TO THE STRAITS OF FLORIDA 
WILL REACH FROM 29N65W TO NEAR CENTRAL BAHAMAS THIS AFTERNOON 
AND MOVE E OF AREA TONIGHT. NLY WINDS OF 15 TO 20 KT ARE NOTED 
BEHIND THE FRONT PER SURFACE DATA. BEHIND THE FRONT...A LARGE 
AND STRONG AREA OF HIGH PRES WILL BUILD SE ACROSS THE REGION 
TIGHTENING THE PRES GRADIENT WITH INCREASING WINDS AND SEAS 
PRIMARILY IN THE SOUTHERN WATERS THROUGH FRI. EXPECT NE TO E 
WINDS IN THE 20 TO 25 KT RANGE BEGINNING LATE TUE...WITH SEAS 
BUILDING 6-9 FT E OF THE BAHAMAS. WEAK SURFACE TROUGH FROM 
DOMINICAN REPUBLIC NE TO 22N65W WILL SLOWLY WEAKEN THROUGH 
TONIGHT.

CARIBBEAN SEA AND TROPICAL N ATLC...
HIGH PRES WILL BUILD SE ACROSS THE SW N ATLC DURING THE FORECAST 
PERIOD TIGHTENING THE PRES GRADIENT ACROSS THE CARIBBEAN SEA AND 
THE NORTHERN PORTION OF THE TROPICAL N ATLC. THIS WILL ALLOW FOR 
TRADES TO INCREASE ACROSS MUCH OF THE REGION THROUGH FRI. 20-25 
KT NE TO E TRADES ACROSS THE SRN CARIBBEAN WILL EXPAND N AND NW 
TONIGHT AND COULD INCREASE TO AROUND 30 KT OFF THE COAST OF 
COLOMBIA WITH BUILDING SEAS TO AROUND 13 FT. ELY WINDS OF 20-25 
KT SHOULD COVER ALL BUT THE FAR EASTERN CARIBBEAN THROUGH FRI. E 
OF AROUND 65W...E WINDS WILL BE IN THE 15-20 KT RANGE.

A SERIES OF LOW AMPLITUDE TROPICAL WAVES WILL MOVE ACROSS S 
PORTIONS OF THE TROPICAL ATLC OVER THE NEXT FEW DAYS. ENHANCED 
MOISTURE WITH SHOWERS AND TSTMS ARE EXPECTED WITH AND JUST AHEAD 
OF THESE WAVES. ONE OF THEM IS CURRENTLY MOVING ACROSS THE FAR S 
PART OF THE TROPICAL N ATLC WITH ISOLATED TO SCATTERED SHOWERS.
