northern Bahamas. Gale force W to NW winds are expected to end by
early this morning N of 30N. By 1200 UTC, the gale force winds
will shift north of 31N. Seas will peak near 15 ft this morning

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic from the Senegal/The Gambia
border near 13N17W to 09N21W. The ITCZ extends from 01S20W to
00N34W to 01N48W. Scattered moderate to isolated strong convection
is noted off the coast of Liberia and Sierra Leone in addition to
the eastern portions of the ITCZ from 04S to 07N and E of 25W.
Scattered moderate convection is noted along the ITCZ from 04S to
04N W of 26W.

...GULF OF MEXICO...

A dome of 1021 mb high over the central Gulf is dominating the
entire basin. Light to gentle winds with seas at 2 to 4 ft are
seen over the central and N central Gulf. Fresh to strong E to SE
return flow are evident over W Gulf. Buoy 42020 off the coast of
Corpus Christi, TX is reporting seas are up to 9 ft. Moderate to
fresh N to NE winds and seas of 5 to 7 ft prevail for the rest of
the basin, including the Yucatan Channel.

For the forecast, fresh winds will expand across the eastern Gulf
on Mon through Wed as the high pressure shifts eastward out of
the basin. The fresh to strong winds across the western and
central Gulf will continue through Wed. A weak cold front could
potentially move off the Texas coast on Thu, move into the
northern Gulf and stall.

...CARIBBEAN SEA...

Convergent trade winds are causing scattered showers and
thunderstorms near the Costa Rica-Panama border and adjacent
waters. A stationary front extends from E Cuba across the coast of
north-central Honduras. Patchy showers are occurring up to 60 nm
NW, and up to 110 nm SE of the front, including Jamaica. Fresh NE
winds and 5 to 7 ft seas are found behind the front over the NW
basin. Fresh to strong NE to ENE trades with seas at 8 to 10 ft
are noted over the S central basin, just N of Colombia. Moderate
to fresh NE to E trades and seas of 4 to 6 ft prevail for the
remainder of the basin.

For the forecast, fresh to strong northeast to east trade winds
will prevail in the south-central Caribbean through at least Thu
night. The stationary front will dissipate by this evening. Winds
will continue to prevail at moderate to fresh speeds through Thu
for most of the NW and eastern Caribbean. High pressure building
in behind the front will increase northeast to east winds across
portions of the northwest and central Caribbean from tonight
through at least Wed night. Fresh to strong east to southeast
winds will pulse in the Gulf of Honduras at night from Tue through
Thu.

...ATLANTIC OCEAN...

Please read the Special Features section for more information on
a Gale Warning.

The primary front in the west-central Atlantic is stalled from
31N67W to 21N75W in eastern Cuba. A secondary reinforcing cold
front extends from W of Bermuda across 31N69W to the northern
Bahamas. Scattered showers are found near both fronts from the N
coast of Cuba, northward across the central and NW Bahamas to
beyond 31N. Outside the Gale Warning area, strong to near-gale W
to NW winds and 8 to 12 ft seas are present N of 27N between 64W
and 79W. Fresh to locally strong NW winds and seas at 5 to 8 ft
are seen N of 24N between 80W and the Georgia- Florida coast.
Moderate to fresh NW to NE winds with seas at 3 to 6 ft prevail
through most of the Bahamas.

Farther east, a third cold front curves west-southwestward from W
of Madeira across 31N23W to 27N30W to 27N42W, then continues
westward as a surface trough to 25N52W. Cloudiness and scattered
showers are occurring near these features N of 25N between 22W
and 50W. Despite the presence of gentle to moderate northerly
winds, persistent northerly swell is sustaining 8 to 10 ft seas N
of 25N between the Canary Islands and 49W. Farther south,
moderate to fresh NNE to NE trades with 5 to 8 ft seas are
present S of 21N between 35W and 61W/Lesser Antilles, and also
from 10N to 25N between the African coast and 35W. Light to gentle
winds and seas at 4 to 5 ft prevail for the remainder of the
Atlantic Basin.

For the forecast W of 55W, the primary front will reach from near
31N62W to 25N67W to the Windward Passage this afternoon, and from
31N55W to north of Haiti by Mon morning. The gale-force winds are
expected to end this morning as the two fronts merge together.
Winds will continue to diminish to moderate to fresh speeds
tonight along the front. High pressure will move eastward along
30N/31N through midweek, which will improve conditions over most
of the forecast waters. This high pressure will lead to increasing
northeast to east winds near the Windward Passage tonight through
Thu night.
