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

.SYNOPSIS...Weak high pressure prevails north of the area across
the western Atlantic. This pattern supports moderate to fresh NE
to E trade winds offshore of northwestern Colombia and in the
Gulf of Venezuela pulsing to fresh to strong during the evening
and early morning hours through Tue morning. A similar scenario
is also expected across the Gulf of Honduras overnight. Looking
ahead, a cold front will move across the Gulf of America and
enter the northwestern Caribbean on Mon evening, reach from
central Cuba to the Gulf of Honduras Tue morning, then stall
from eastern Cuba to Belize Wed before dissipating Wed night.
Expect fresh to locally strong N winds and locally rough seas
behind the front through Tue morning.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A frontal boundary extending between northeast
Florida and Bermuda will lift north overnight ahead of low
pressure approaching the area from the west. The low pressure
will move off the Georgia coast early Mon. An associated cold
front will move off the northeast Florida coast late Mon,
associated by increased winds and seas. The front will reach
from Bermuda to central Cuba, followed by strong to gale-force
winds and rough to very rough seas. The low will lift out to the
northeast by mid week, as the front weakens as it moves east of
the area, with a trailing portion stalling along rough 20N before
dissipating Thu. Winds and seas will dissipate from west to east
through late week as high pressure builds over the western
Atlantic in the wake of the front.
