Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...Moderate to fresh trade winds will prevail over the
central and eastern Caribbean through Tue, as a surface trough
moves westward through the region, and high pressure builds to
the north. Locally strong winds and rough seas are expected in
the south-central and portions of the north-central Caribbean
during the weekend and on Mon. Rough seas in N swell will
continue over the tropical Atlantic waters east of the Lesser
Antilles into Mon and then will gradually subside through late
Tue. Looking ahead, a strong cold front is slated to enter the
NW Caribbean late Mon, leading to widespread strong to near gale
force N winds and rough seas in the wake of the front. The cold
front is forecast to reach from E Cuba to E Honduras Tue evening
where it will stall before it starts to weaken Tue night into
Wed.
