MARINE WEATHER HF VOICE BROADCAST
NWS NATIONAL HURRICANE CENTER MIAMI, FL
1011 AM EDT FRI SEP 5 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 RIDGE AND
THE COLOMBIAN LOW WILL CONTINUE TO SUPPORT MODERATE TO FRESH
EASTERLY TRADE WINDS ALONG WITH MODERATE SEAS ACROSS MUCH OF THE
CENTRAL CARIBBEAN INTO EARLY SUN. FRESH TO LOCALLY STRONG WINDS
ARE EXPECTED TO PULSE OFF COLOMBIA AND THE GULF OF VENEZUELA
TONIGHT AND SAT NIGHT. IN ADDITION, MODERATE TO LOCALLY FRESH E
WINDS AND SLIGHT TO MODERATE SEAS WILL PREVAIL IN THE GULF OF
HONDURAS THROUGH SAT NIGHT. LOOKING AHEAD, THERE IS A MEDIUM
CHANCE LOW PRESSURE CURRENTLY IN THE EASTERN ATLANTIC MAY
DEVELOP INTO A TROPICAL CYCLONE OVER THE NEXT 48 HOURS, AND A
HIGH CHANCE IT WILL DEVELOP THROUGH THE NEXT SEVEN DAYS AT IT
MOVES WESTWARD. AT A MINIMUM, THIS FEATURE MAY BRING STRONG
WINDS AND ROUGH SEAS TO THE ATLANTIC WATERS EAST OF THE LEEWARD
ISLANDS BY THE MIDDLE OF NEXT WEEK.
