SYNOPSIS
FRESH TO STRONG EASTERLY TRADE WINDS WILL OCCUR ACROSS
THE CENTRAL CARIBBEAN, INCLUDING THROUGH THE WINDWARD PASSAGE,
THIS WEEKEND THROUGH EARLY NEXT WEEK AS A STRONG PRESSURE GRADIENT
PREVAILS BETWEEN THE COLOMBIAN LOW AND BUILDING HIGH PRESSURE TO
THE NORTH. PERIODS OF NEAR-GALE FORCE WINDS WILL BE POSSIBLE OFFSHORE
OF NORTHWESTERN COLOMBIA AND IN THE GULF OF VENEZUELA. BUILDING
ROUGH SEAS WILL OCCUR IN TANDEM WITH THE STRONG WINDS, WITH THE

SYNOPSIS FOR THE THE SW N ATLANTIC INCLUDING THE BAHAMAS
SYNOPSIS
MODERATE TO LOCALLY FRESH SE-S WINDS WILL AFFECT THE

LOW PRESSURE SYSTEM. THE COLD FRONT WILL ENTER THE WESTERN ATLANTIC
AND LIFT NORTHEASTWARD BY MIDWEEK. ELSEWHERE, PULSING MODERATE
TO FRESH E TO SE WINDS ARE EXPECTED EAST OF 65W THROUGH SUN, ON
THE PERIPHERY OF HIGH PRESSURE IN THE CENTRAL ATLANTIC. MODERATE
