Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 31N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0444 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough is confined to the African continent. The ITCZ
enters the Atlantic through the coast of Sierra Leone near 08N13W
to 05N24W to 04N35W to 00N47W. Scattered moderate convection is
observed on satellite imagery from 02N to 07N and between 16W and
33W.

GULF OF MEXICO...

A stationary front extends from southern Florida to the NE tip of
the Yucatan peninsula. Isolated showers are noted near the
frontal boundary. The deep upper level trough over the SE United
States is also enhancing the development of isolated showers
across the E Gulf, affecting central and southern Florida, and
producing a large area of cloudiness across the SE Gulf and E Bay
of Campeche. Meanwhile, a strong 1024 mb high pressure dominates
the northern and western Gulf, allowing a dry continental to
filter in and welcoming tranquil weather conditions. Surface
observations and a recent scatterometer satellite pass show that
fresh to strong NE-N winds are affecting the waters from SW
Florida to the Bay of Campeche. Seas in this region are 5-10 ft,
with the highest seas occurring in the Bay of Campeche. Moderate
or weaker winds and seas of 2-5 ft are present elsewhere.

For the forecast, the aforementioned front will persist through
Thu. Winds and seas are diminishing across the Gulf as high
pressure settles over the northern Gulf. Looking ahead, the next
cold front is forecast to enter the northwest Gulf by Sat. Gale
conditions are possible behind the front Sat night and Sun over
the western Gulf.

CARIBBEAN SEA...

A stationary front extends from southern Florida to the NE tip of
the Yucatan peninsula, producing some isolated showers over the
Yucatan Channel and NW Caribbean Sea. A weak surface trough is
found near the Cayman Islands but no significant convection is
associated with this feature. The rest of the basin enjoys fairly
tranquil weather condition. A recent scatterometer satellite pass
indicate that moderate to fresh trades are found in the central
and eastern Caribbean and the Yucatan Channel. Seas in the region
are 3-6 ft, with the highest seas occurring offshore NW Colombia. Moderate
or weaker winds and seas of 1-3 ft prevail elsewhere.

For the forecast, high pressure over the central Atlantic will support
moderate to fresh trade winds across the eastern and central
Caribbean through mid week pulsing to strong off Colombia mainly
at night. A weak front will remain nearly stationary over the NW
Caribbean trough Fri while weakening. The aerial extent of the
fresh to strong trades will begin to increase on Fri, covering
most of the east and central Caribbean late Fri through Sun.

ATLANTIC OCEAN...

A stationary front extends from a weak low pressure between Cape
Hatteras and Bermuda to southern Florida, entering the tropical
Atlantic near 31N74W. Scattered showers are seen between the
frontal boundary the coast of Florida. Nearby, a weak surface
trough extends from 30N72W to 26N75W and a few weak showers are
occurring within 60 nm to the east of the system. Recent scatterometer
satellite data depict fresh to locally strong winds within 120 nm
of the frontal boundary and surface trough. Seas in the described
area are 3-6 ft.

A weak 1011 mb low pressure system is located near 25N34W and a
surface trough extends from the center to near 15N41W. Scattered
showers are noted in the eastern quadrant of the low pressure.
Satellite-derived wind data indicate that fresh to locally strong
NE winds are occurring N of 22N and between the low pressure and
50W. Seas in the region are 5-8 ft. Elsewhere, moderate or weaker
winds and seas of 3-6 ft prevail.

For the forecast west of 65W, the aforementioned will start to
move eastward on Wed, as a weak low pressure develops along the
frontal boundary north of the northern Bahamas. The front will
stall again, from 31N68W to the central Bahamas late Thu into Fri,
before lifting north of the area as a warm front on Sat. The next
cold front is forecast to move off NE Florida on Sun.
