355 PM EST SAT DEC 21 2024
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
MODERATE TO LOCALLY FRESH N TO NE WINDS WILL PREVAIL
ACROSS THE WESTERN HALF OF THE CARIBBEAN THROUGH SUN AS A
WEAKENING COLD FRONT DRIFTS SOUTHWARD ACROSS THE SE BAHAMAS AND
ADJACENT ATLANTIC THIS WEEKEND. ELSEWHERE, MODERATE TO LOCALLY
FRESH TRADES ARE EXPECTED OVER THE CENTRAL AND EASTERN
CARIBBEAN. HIGH PRESSURE WILL BUILD OVER THE EASTERN UNITED
STATES AND WESTERN ATLANTIC EARLY NEXT WEEK. A STRENGTHENING
PRESSURE GRADIENT BETWEEN THE HIGH PRESSURE AND THE LINGERING
COLD FRONT JUST N OF THE CARIBBEAN WILL LEAD TO FRESH TO LOCALLY
STRONG NE TO E WINDS ACROSS MUCH OF THE BASIN SUN NIGHT THROUGH
TUE, WITH WINDS AND SEAS THEN GRADUALLY DIMINISHING THROUGH MID
WEEK.

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
A COLD FRONT EXTENDS FROM 31N65W TO THE CENTRAL
BAHAMAS AND EAST-CENTRAL CUBA THIS AFTERNOON, AND WILL PROGRESS
SLOWLY SOUTHEASTWARD THROUGH EARLY NEXT WEEK. FARTHER EAST, A
BROAD RIDGE IS DRIFT EASTWARD, AND WILL PRODUCE MODERATE TO
FRESH S TO SE WINDS ALONG THE W PERIPHERY OF THE RIDGE,
GENERALLY NORTH OF 20N AND EAST OF 60W THROUGH TONIGHT. SOUTH OF
20N, MODERATE TO BRIEFLY FRESH TRADES WILL PREVAIL INTO THE
MIDDLE OF NEXT WEEK. AN INVERTED TROUGH IS FORECAST TO DEVELOP
EAST OF THE BAHAMAS SUN THEN DRIFT WESTWARD TO ALONG THE EAST
COAST OF FLORIDA BY LATE MON. A LOW CENTER IS LIKELY TO FORM NEAR
THE NE FLORIDA COAST MON NIGHT AND SHIFT NORTHWARD. A STRONG
HIGH PRESSURE RIDGE WILL SHIFT INTO THE WESTERN ATLANTIC DURING
THIS TIME. THE TIGHTENING PRESSURE GRADIENT BETWEEN THE HIGH
PRESSURE, THE LINGERING FRONT, AND THE TROUGH WILL INDUCE A BROAD
SWATH OF FRESH TO STRONG NE TO E WINDS AND VERY ROUGH SEAS TO
THE EAST OF THE BAHAMAS MON AFTERNOON, SHIFTING WESTWARD ACROSS
THE BAHAMAS THROUGH TUE, THEN QUICKLY DIMINISH. THE COLD FRONT IS
EXPECTED TO ALIGN NEARLY W TO E ALONG ABOUT 21N BY TUE NIGHT
BEFORE DISSIPATING ON WED.
