...Monsoon trough/ITCZ...


The monsoon trough emerges from the coast of Liberia in western
Africa near 08n13w and extends to 03n20w. The ITCZ continues from
that point to the coast of Brazil near 02n50w. Scattered moderate
convection is noted along and in the vicinity of the ITCZ from
01n-06n between 16w-36w.


Gulf of Mexico...


A 1034 mb surface high is centered over the northeast Atlantic
with a ridge axis extending southwestward over Florida into the
eastern Gulf of Mexico. A strengthening low pressure system is
over eastern Alabama dragging a cold front over the Gulf. The
front extends from 30n87w to 18n93w. Gale-force winds are
currently ongoing behind the front over a portion of the western
Gulf. Refer to the special features section above for more
details. Strong to near gale-force winds cover the remainder of
the Gulf. Numerous showers and thunderstorms are organized in a
line within 150 nm E of the front mainly N of 24n.


The cold front will continue to move across the Gulf waters
tonight, shifting E of the area through the next 24 hours. Winds
and seas will diminish across the Gulf on Thu as the front moves
southeast of the region. Winds and seas will increase this weekend
as another frontal boundary moves through the basin.


Caribbean Sea...


A 1034 mb high pressure north of the area is inducing widespread
fresh to strong trade winds over most of the Caribbean basin.
Earlier scatterometer data showed gale-force winds near the coast
of Colombia. Expect for these winds to prevail through Thu night,
with gale-force winds pulsing off of colombia's coast at night.
Refer to the special features section for more details. Expect
seas well over 8 feet for much of the central Caribbean through
Thu night, highest over the south-central Caribbean, where 10-15
ft seas are expected.


Winds and seas will diminish late in the week as the high pressure
shifts east ahead of another cold front. This cold front is
expected to move into the northwest Caribbean by late Thu. The
front will stall and dissipate from central Cuba to the Gulf of
Honduras by late Fri.


Atlantic Ocean...


Surface ridging prevails across the west Atlantic. To the east, a
cold front extends from 32n40w to 20n58w. It continues as a
stationary front from 20n58w to 19n76w. Scattered moderate
convection is N of 25n between 34w-40w. Surface ridging extending
from high pressure N of the Azores prevails across the eastern
Atlantic.


The cold front over the central Atlantic will weaken late this
week. High pressure building in the wake of the front will
maintain fresh to strong winds over the central Atlantic waters
through late Thu. High pressure over the western Atlantic will
shift eastward ahead of a cold front moving off the coast of
Florida Thu. Southerly gale-force winds will prevail N of 29n E
of the front Thu. Refer to the special features section for more
details. This front will stall and dissipate from Bermuda to
eastern Cuba by Sat. A weak reinforcing front will move off
northeast Florida by late Sat, and reach from Bermuda to The
Straits of Florida by late sun.
