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 1800 UTC surface analysis and satellite imagery through
2350 UTC.

...TROPICAL WAVES...

A tropical wave extends from 07N to 20N with axis along 23W,
moving W at 10-15 kt. There is no convection associated with this
wave.

A tropical wave extends from 05N to 20N with axis near 42W, moving
W at 10-15 kt. Scattered moderate convection is from 06N to 13N
between 37W and 47W.

A tropical wave extends S of 16N with axis near 70W, moving W at
15-20 kt. There is no convection associated with this wave.

A tropical wave extends S of 20N with axis near 85W, moving W at
10-15 kt. Scattered showers and tstorms are inland and offshore
Honduras.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 19N16W to 10N24W to 10N38W to
08N45W. The ITCZ continues from 08N45W to the coast of Guyana near
08N59W. Scattered moderate convection is from 06N to 11N between
11W and 17W, from 08N to 12N between 25W and 35W, and from 06N to
11N W of 50W.

GULF OF MEXICO...

High pressure ridging associated with the western periphery of the
subtropical Atlantic high continues to guide conditions in the
Gulf of Mexico. At 2100 UTC, a surface trough remains in the Bay
of Campeche, supporting scattered moderate convection between the
trough and the eastern coast of Mexico to just N of Tampico.
Otherwise, light to gentle return flow prevails with 2-4 ft seas,
except for moderate to fresh E to NE winds off the Yucatan
peninsula.

For the forecast, weak surface ridging extending across the
northern Gulf will continue to support gentle to moderate winds
and slight seas across most of the Gulf through the week. Fresh E
winds will pulse during the evening hours through mid week west of
the Yucatan Peninsula due to a diurnal trough.

CARIBBEAN SEA...

Fresh to near gale force trades prevail across the central and
portions of the SW Caribbean, being the strongest winds along the
coast of Colombia. These winds are generating 8-12 ft seas in E
swell. Strong NE winds are also occuring across the Windward
Passage. Moderate to locally fresh trades are across the E
Caribbean and in the NW basin S of 19N, including the Gulf of
Honduras.

For the forecast, fresh to strong trade winds and rough seas will
persist over the central Caribbean into mid-week, then will
diminish slightly. The eastern Caribbean will experience moderate
to fresh trades, while the northwest Caribbean can expect mainly
gentle to moderate E winds and slight seas through Sat.

ATLANTIC OCEAN...

1023 mb high pressure is centered near 29N70W. A weak stationary
front enters the area near 31N48W and continues to 31N56W. High
pressure ridging dominates the remainder of the tropical
Atlantic. The latest scatterometer data shows gentle to moderate
anticyclonic flow across the basin. Seas are 3-6 ft, with lowest
seas in the W Atlantic near the FL Coast and the N Bahamas.

For the forecast west of 55W, the ridge will prevail along 30N
through Tue, then will lift north of the area. Fresh to strong
winds will pulse north of Hispaniola and in the approaches to the
Windward Passage during the late afternoon and overnight hours
through tonight.
