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
0530 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from W Africa near 09N13W to 05N19W.
The ITCZ begins near 05N19W and passes south of the equator near
39W. Scattered moderate convection is within 30 nm either side
of a line from 04N22W to 02N35W.

...DISCUSSION...

GULF OF MEXICO...

A ridge extends from the western Atlantic across the northern
Gulf. Moderate E to SE surface flow covers the Gulf with mostly
fair weather. Return flow over the SW Gulf could become strong
later today in response to deepening low pressure in the central
U.S. Weak surface troughing will develop over the Yucatan
Peninsula each day, then shift west into the Bay of Campeche at
night. A dry weather pattern is expected to remain in place for
the next two days. A cold front will enter the northwest Gulf on
Wed and reach the southeast Gulf by Wed night.

CARIBBEAN SEA...

Undersea volcano Kick 'em Jenny, is north of Grenada near 12.18N
61.38W. The government of Grenada advises mariners to observe a
permanent 1.5 km or 0.8 nm exclusion zone around the volcano.
Please see www.nadma.gd for additional information.

High pressure NE of the area in the Atlantic will maintain fresh
trades in the south-central Caribbean the next few days. Locally
strong winds are possible near the coast of Colombia at night.
Light to moderate trades elsewhere will weaken slightly through
Thu as the ridge weakens. A surface trough along 64W will drift
into the central Caribbean through Wed. Mostly dry weather will
continue over the remainder of the basin the next couple days as
a mid-level ridge extends N over the basin from South America.

ATLANTIC OCEAN...

A weak surface trough in the central Atlantic extends from
32N49W to 29N55W. The trough will shift eastward the next couple
of days. A ridge in the central Atlantic along 31N will maintain
moderate to fresh trade winds and mostly fair weather over the
tropical Atlantic west of 25W through Thu. A cold front will
enter the western Atlantic Wed night and move into the central
Atlantic on Fri.
