MARINE WEATHER HF VOICE BROADCAST FOR THE TROPICAL N ATLANTIC
FROM 07N TO 22N BETWEEN 55W AND 64W...THE SW N ATLANTIC S OF
31N W OF 65W INCLUDING BAHAMAS...AND THE CARIBBEAN SEA.

SEAS GIVEN AS SIGNIFICANT WAVE HEIGHT...WHICH IS THE AVERAGE
HEIGHT OF THE HIGHEST 1/3 OF THE WAVES. INDIVIDUAL WAVES MAY BE
MORE THAN TWICE THE SIGNIFICANT WAVE HEIGHT.

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

.SYNOPSIS...A WEAKENING COLD FRONT EXTENDS FROM 22N55W SW TO THE
LEEWARD ISLANDS. THIS FRONT WILL CONTINUE TO MOVING SLOWLY TO
THE SE WHILE GRADUALLY DISSIPATING THROUGH FRI. WEAK HIGH PRES
BUILDING N OF THE CENTRAL CARIBBEAN BEHIND FRONT WILL SUPPORT
MAINLY MODERATE TO FRESH WINDS ACROSS MOST OF THE CARIBBEAN
WATERS...EXCEPT FOR STRONG WINDS DEVELOPING AT NIGHT ALONG THE
COAST OF COLOMBIA AND IN THE GULF OF HONDURAS. NORTHERLY SWELL
SUBSIDING IN THE NORTHERN TROPICAL N ATLC WILL BE REPLACED BY A
LARGER BATCH OF LONG PERIOD NORTHERLY SWELL BEGINNING ON SAT.
THIS NORTHERLY WILL PROPAGATE THROUGH ALL OF THE TROPICAL N ATLC
ZONES INTO MON.

SYNOPSIS FOR THE SW N ATLC INCLUDING THE BAHAMAS

.SYNOPSIS...WEAK HIGH PRES OVER THE WESTERN PORTION WILL BEGIN
TO SHIFT ESE THIS AFTERNOON IN RESPONSE TO A COLD FRONT THAT IS
MOVING SSE ACROSS THE NORTH-CENTRAL AND NE WATERS. THE FRONTAL
PORTION E OF 72W WILL CONTINUE AS A COLD FRONT EXITING THE AREA
TONIGHT...WHILE THE PORTION W OF 72W LIFTS BACK TO THE N AS A
WARM FRONT THROUGH FRI. AS THIS TAKES PLACE...THE NEXT COLD FRONT
WILL BE APPROACHING THE SE U.S. THIS FRONT WILL EMERGE OUT OVER
THE FAR NW WATERS ON FRI NIGHT...MOVE ACROSS THE NORTH- CENTRAL
WATERS ON SAT AND ACROSS THE NE WATERS ON SAT NIGHT EXITING THE
BASIN ON SUN. THE FRONT WILL BE PRECEDED BY STRONG SOUTHERLY
WINDS OVER THE NORTHERN WATERS...WITH STRONG W TO NW WINDS OVER
THE NE WATERS SAT NIGHT AND SUN. HIGH PRES IN THE WAKE OF THE
FRONT WILL SLIDE EASTWARD TO THE NORTHEAST WATERS BY LATE MON AS
DEEPENING LOW PRES TRACKS NE OVER THE SE U.S. THE COMBINATION
BETWEEN THE LOW PRES AND THE HIGH PRES IS EXPECTED TO BRING
INCREASING SOUTHERLY WINDS AND BUILDING SEAS TO THE NW PORTION
EARLY NEXT WEEK. A NEW SET OF LARGE N TO NE SWELL WILL PROPAGATE
INTO THE EASTERN PORTION OF THE BASIN TONIGHT THROUGH LATE SUN.
