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 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0445 UTC.

...SPECIAL FEATURES...

None.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from Liberia on the African coast near
07N11W to 05N14W. The ITCZ continues from 05N14W to 01N40W to the
coast of Brazil near 01S46W. No significant convection is
currently associated with these features.

...DISCUSSION...

GULF OF MEXICO...

A cold front exited to the SE of the basin on Tue. Residual
troughing over the SW Bay of Campeche is maintaining an area of
cloudiness over the SW Gulf S of 27N and W of 90W. High pressure
ridging S from the Central Plains is generally maintaining
moderate NE winds over the Gulf. A tighter pressure gradient over
southern Mexico is supporting fresh winds over the Bay of
Campeche. The high will migrate SE from the central plains to the
NE Gulf by Fri. Moderate to fresh NE winds will gradually veer to
SE as the high pressure migrates to the NE Gulf. Return flow on
the west side of the high will become moderate to fresh on Fri.

CARIBBEAN SEA...

A cold front extends from eastern Cuba near 20N78W to Belize near
18N88W. The front is slowing down and will stall from Hispaniola
to Nicaragua on Wed, then dissipate by Thursday. Fresh to strong
trades are observed N of the cold front as well as the waters S of
18N and east of 80W. Deep layer low pres will linger near the NE
United States during the next few days. This will keep the ridge N
of the Caribbean weak and cap winds along the coast of Colombia
generally between 20 and 25 kt during the next few days.
Otherwise, light to moderate trades and relatively dry conditions
are expected to prevail during the next several days as mid to
upper-level ridging extending over the basin from the SE maintains
a benign weather pattern.

ATLANTIC OCEAN...

A cold front extends across the west Atlantic from 32N57W to
25N67W to eastern Cuba near 20.5N74.5W. Winds along the front
continue to subside as the parent low centered S of Maine lifts
farther N. Scattered showers are present along and up to 60 nm NW
of the front N of 28N. The convection associated with the front
will shift eastward and diminish tonight as the front continues
slowly pushing east. The front is slowing down and will stall from
32N56W to 26N65W to E Cuba tonight. A secondary cold front
pushing SE from the Mid Atlc States will cause the northern part
of the front to begin moving east again by Wednesday night before
the two boundaries merge. The combined front will then dissipate
into a trough by the end of the week. High pres will build from
the NW behind the front late Wed and shift E into the W Atlc along
27N Fri and Sat. Otherwise, a broad area of high pressure
prevails across the central and eastern Atlantic, anchored by a
1024 mb high centered near 27N38W. The high is maintaining
moderate to fresh NE winds over the tropical Atlantic N of the
ITCZ between 30W and the Windward Islands.
