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

.SYNOPSIS...A weak and narrow Atlantic ridge extends westward
along 24N-25N into the NW Bahamas. The associated pressure
gradient between the ridge and lower pressure over SE Mexico is
supporting fresh to strong SE winds across the Gulf of Honduras,
and fresh to locally strong E winds in the south-central
Caribbean. Strong winds in the Gulf of Honduras will persist
through Sun morning, reaching near gale-force this evening into
Sat morning and again Sat night. Fresh to strong winds will
pulse at night in the Gulf of Venezuela and offshore Colombia
through Mon night. High pressure from the eastern Atlantic will
build westward Wed and Wed night leading to increasing trade
winds over most of the central and eastern Caribbean. Dense
smoke due to agricultural fires in Central America continues
across areas of the northwestern Caribbean, and is significantly
reducing visibility across the Gulf of Honduras.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A frontal trough extends from 31N59W southwestward 
to 26N70W and northwestward to 30N80W. Clusters of scattered 
showers and thunderstorms continue along the front E of 65W. The
cold front will move slowly eastward, and shift east of 55W
early Mon, with active weather expected to continue ahead of the
front through Sun. Moderate to locally fresh winds and moderate 
seas are expected across most of the area through Sun night as 
weak high pressure extends E to W roughly along 24N-25N. A new 
front will sink southward into the waters offshore of Georgia and
NE Florida early Mon, and move southeastward and weaken through 
late Tue. A residual trough may linger from near 30N71W to the 
central Bahamas Wed and Wed night.
