1116 PM EDT FRI AUG 1 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
THE PRESSURE GRADIENT BETWEEN THE ATLANTIC HIGH
PRESSURE AND THE COLOMBIA LOW WILL CONTINUE TO ALLOW FOR FRESH
TO STRONG WINDS AND ROUGH SEAS OVER THE SOUTH-CENTRAL CARIBBEAN
THROUGH WED NIGHT. THE STRONGEST WINDS WILL OCCUR OFF THE COAST
OF COLOMBIA, OCCASIONALLY PULSING TO NEAR GALE-FORCE AT NIGHT.
MODERATE TO FRESH TRADES WILL PREVAIL OVER THE E CARIBBEAN WHILE
MODERATE OR WEAKER WINDS ARE FORECAST FOR THE NW CARIBBEAN.
OTHERWISE, A TROPICAL WAVE ACCOMPANIED BY SCATTERED SHOWERS AND
THUNDERSTORMS, CURRENTLY MOVING ACROSS THE LESSER ANTILLES, WILL
MOVE ACROSS THE EASTERN CARIBBEAN ON SAT, THE CENTRAL CARIBBEAN
SAT NIGHT INTO SUN AND ACROSS THE SW BASIN SUN NIGHT INTO MON.

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
HIGH PRESSURE WILL DOMINATE THE WEATHER PATTERN
THROUGH THE PERIOD, SUPPORTING A GENTLE TO MODERATE ANTICYCLONIC
FLOW AND SLIGHT TO MODERATE SEAS. THE PRESSURE GRADIENT BETWEEN
A TROPICAL WAVE CURRENTLY MOVING ACROSS THE LESSER ANTILLES AND
THE ATLANTIC HIGH PRESSURE WILL SUPPORT AN AREA OF FRESH TO
LOCALLY STRONG E TO SE WINDS WITH MODERATE TO ROUGH SEAS THAT
WILL MOVE NORTH OF THE LEEWARD ISLANDS AND PUERTO RICO THROUGH
SAT AND N OF HISPANIOLA SAT NIGHT INTO SUN. WINDS AND SEAS WILL
DIMINISH SUN AS THE HIGH PRESSURE WEAKENS SOME.
