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...STRONG HIGH PRES PUSHING E INTO THE W ATLC FROM THE
MID ATLC STATES WILL MAINTAIN STRONG NE WINDS ACROSS THE NW AND

LATE FRI NIGHT AND PREVAIL THROUGH SUN. LOW PRES DEVELOPING N OF
THE CARIBBEAN WILL ALLOW WINDS AND SEAS TO GRADUALLY SUBSIDE SUN
