939 PM EDT FRI MAY 2 2025
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
HIGH PRESSURE OVER THE WESTERN ATLANTIC COMBINED
WITH THE COLOMBIAN LOW WILL SUPPORT FRESH NORTHEAST WINDS
THROUGH THE WINDWARD PASSAGE, IN THE LEE OF CENTRAL CUBA, AND
SOUTH OF THE DOMINICAN REPUBLIC, MAINLY NEAR CABO BEATA,
TONIGHT. MODERATE TO FRESH E TO SE WINDS WILL PULSE NORTH OF
HONDURAS, INCREASING TO FRESH TO STRONG TUE NIGHT AND WED NIGHT.
UNSETTLED WEATHER IS EXPECTED TO CONTINUE OVER MOST OF THE
EASTERN CARIBBEAN INTO THE WEEKEND. OTHERWISE, GENTLE TO
MODERATE TRADES AND SLIGHT TO MODERATE SEAS ARE EXPECTED OVER
THE BASIN INTO EARLY NEXT WEEK.

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A SURFACE TROUGH EXTENDS FROM A 1018 MB LOW PRESSURE
NEAR 29.5N52W TO A 1014 MB LOW PRESSURE NEAR 25N51W TO 14N59W.
THESE FEATURES WILL GENERALLY PERSIST OVER THE CENTRAL ATLANTIC
BETWEEN 50W AND 60W THROUGH SAT. FRESH TO STRONG NE TO E WINDS
AND MODERATE TO ROUGH SEAS ARE EXPECTED OVER THE NW PART OF IT
TONIGHT AND SAT DUE TO THE PRESSURE GRADIENT BETWEEN THE
TROUGH/LOW AND HIGH PRESSURE TO THE N. MEANWHILE A COLD FRONT
FROM 31N60W TO 30N65W TO 31N69W WILL MERGE WITH THESE FEATURES
SAT. THE LOWS SHOULD DISSIPATE BY SUN, WHILE THE TROUGH IS
FORECAST TO DRIFT WESTWARD OVER THE FORECAST WATERS THROUGH AT
LEAST EARLY NEXT WEEK. AN AREA OF FRESH TO STRONG EASTERLY WINDS
AND ROUGH SEAS WILL PERSIST NEAR THE NORTHERN END OF THE TROUGH
AXIS AFFECTING MAINLY THE NE WATERS. LOOKING AHEAD, A WEAK COLD
FRONT MAY APPROACH THEN STALL NEAR THE SOUTHEASTERN U.S. COAST
