from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.

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...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 cold front extends from 31N61W southwestward to
27N70W then stationary to just north of the NW Bahamas and to
Melbourne, Florida. 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.
