Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...Strong high pressure N of the area will continue to
bring a large area of strong trade winds across the central
Caribbean Sea through tonight. The aerial extent of the trades
will diminish on Mon as a cold front reaches the NW Caribbean.
Fresh N to NE winds with seas building to 9 to 11 ft in the
Yucatan Channel will follow the front. The front will stall over
the NW Caribbean early in the week before retreating back north
of the basin as a warm front by mid-week. Strengthening high
pressure in the wake of the front will bring again a large a
area of fresh to strong trade winds Tue night into Wed.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...By this afternoon, fresh to strong southerly flow
will set up over the waters E of NE Florida to about 70W in
advance of the next cold front. This cold front is expected to
move into the NW forecast waters this evening. Strong to
near-gale force winds are likely on both sides of the front,
with brief gales possible tonight N of 29N between NE Florida
and 73W. Seas will build ahead and behind the cold front. The
front is forecast to stall late Mon night from Bermuda to
central Cuba. By mid-week, the front is expected to lift N as a
warm front. The pressure gradient between very strong high
pressure north of the area and lower pressure associated with
the warm front may induce strong NE to E winds with higher gusts
and building seas to the east of Florida by mid- week. Gale
conditions are possible toward the end of the work-week.
