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 TROPICAL LOW PRESSURE IS LOCATED NEAR 16N58W
1009 MB MOVING W-NW AT AROUND 15 KT. THIS SYSTEM HAS THE
POTENTIAL TO DEVELOP INTO A TROPICAL CYCLONE DURING THE NEXT DAY
OR TWO. IT IS EXPECTED TO MOVE ACROSS THE LEEWARD ISLANDS
TONIGHT...PASS NEAR PUERTO RICO AND THE VIRGIN ISLANDS ON
FRI...AND NEAR HISPANIOLA ON SAT...WITH A GENERAL DIRECTION
TOWARD THE SE BAHAMAS. INTERESTS IN THOSE ISLANDS AND THE
BAHAMAS SHOULD CLOSELY MONITOR THE PROGRESS OF THIS SYSTEM.
