MARINE WEATHER HF VOICE BROADCAST FOR THE TROPICAL N ATLANTIC
FROM 07N TO 19N W OF 55W, THE N ATLANTIC FROM 19N TO
31N W OF 55W INCLUDING THE 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 ATLANTIC FROM
07N TO 19N W OF 55W
SYNOPSIS
A WEAKENING STATIONARY FRONT EXTENDING FROM EASTERN
CUBA TO NEAR CABO GRACIAS A DIOS, NICARAGUA WILL GRADUALLY
DISSIPATE TONIGHT. FRESH TO LOCALLY STRONG E TO SE WINDS ARE
EXPECTED ACROSS THE EASTERN CARIBBEAN TONIGHT INTO SAT, IN THE
WAKE OF A TROPICAL WAVE MOVING ACROSS THE REGION. THESE WINDS WILL
EXPAND TO THE CENTRAL CARIBBEAN BY SAT NIGHT AS THE WAVE
CONTINUES TO MOVE WESTWARD AND A RIDGE REACHES THE NE CARIBBEAN.
MODERATE TO LOCALLY ROUGH SEAS WILL BE ASSOCIATED WITH THE WAVE.
BY EARLY NEXT WEEK, MAINLY MODERATE TO LOCALLY FRESH TRADE WINDS
WILL DOMINATE THE EAST AND CENTRAL CARIBBEAN. MEANWHILE, ANOTHER
COLD FRONT MAY PUSH INTO THE NW CARIBBEAN BY EARLY TUE WHILE THE
ABOVE MENTIONED TROPICAL WAVE MAY REACH THE WESTERN CARIBBEAN.
