NWS NATIONAL HURRICANE CENTER MIAMI, FL
429 PM EDT SUN MAY 11 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
WIDESPREAD FRESH TO STRONG TRADE WINDS AND ROUGH TO
VERY ROUGH SEAS ARE EXPECTED ACROSS THE CENTRAL CARIBBEAN,
INCLUDING THROUGH THE WINDWARD PASSAGE, INTO EARLY WED AS A
STRONG PRESSURE GRADIENT PREVAILS BETWEEN HIGH PRESSURE TO THE
NORTH AND THE COLOMBIAN LOW. PERIODS OF NEAR-GALE FORCE WINDS
WILL BE POSSIBLE OFFSHORE OF COLOMBIA AND THROUGH THE GULF OF
VENEZUELA EACH AFTERNOON AND NIGHT. FARTHER EAST, PULSING
MODERATE TO FRESH E WINDS AND LOCALLY ROUGH SEAS ARE LIKELY
ACROSS THE ATLANTIC PASSAGES INTO THE EASTERN CARIBBEAN THROUGH
MIDWEEK. LOOKING AHEAD, WINDS AND SEAS WILL SLOWLY DIMINISH BY
LATE WEEK.
