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 
0500 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from 16N17W to 05N26W. The ITCZ continues
from 05N26W to 02N50W. Scattered moderate convection is noted south
of 07N between 18W-35W.

Weak high pressure dominates the Gulf of Mexico. Scattered showers
and isolated thunderstorms are affecting the nearshore waters of 
the northern Gulf. Fresh to strong easterly winds are found off 
northern Yucatan, while gentle to moderate E-SE winds prevail 
elsewhere west of 86W. Seas in the area described are 3-5 ft. In 
the rest of the Gulf, light to gentle winds and slight seas are 
prevalent.

For the forecast, high pressure will prevail across the basin. An
inverted trough may develop over the western Gulf early this week
where it may linger through at least mid-week. Moderate to fresh 
return flow will dominate the basin, pulsing to strong near the 
Yucatan Peninsula and Yucatan Channel. Meanwhile, haze due to 
agricultural fires in Mexico continues across most of the western 
Gulf and Bay of Campeche.

...CARIBBEAN SEA...

A weak pressure gradient prevails across the basin, sustaining 
moderate easterly trade winds over most of the basin. The 
exception is the Gulf of Honduras, where strong to near gale E-SE 
winds are currently pulsing. Seas are slight to moderate across 
the basin, with peak seas to 8 ft in the Gulf of Honduras.

For the forecast, high pressure over the central Atlantic will
continue to support strong to near gale E to SE winds near the 
Gulf of Honduras, fresh to locally strong winds in the south-central
basin, and gentle to moderate winds elsewhere tonight. The 
pressure gradient will tighten early this week, with fresh to 
strong trade winds expected in the S-central and in the 
northwestern Caribbean, and moderate to fresh trade winds 
elsewhere. Seas will build next week as a result of the increasing
winds. Meanwhile, haze due to agricultural fires in Central 
America continues across some areas of the northwestern Caribbean.

...ATLANTIC OCEAN...

A weak cold front extends from 31N63W to a 1012 mb low pressure in
the NW Bahamas. A pre-frontal trough is analyzed from 26N63W to
23N68W. Scattered moderate convection is noted north of 23N and 
between 53W-63W. Moderate to fresh winds are noted near the front
mainly north of 28N and between 58W and 68W. Seas in these waters
are 4-6 ft. Light to gentle winds and slight to moderate seas 
prevail elsewhere west of 50W, while moderate to fresh easterly
winds prevail east of 50W.

The remainder of the tropical Atlantic is dominated by a broad 
1031 mb high pressure system centered to the west of the Azores. 
The pressure gradient between this ridge and relatively lower 
pressures in northwest Africa result in fresh to strong northerly 
winds north of 15N and east of 22W. Seas in the area described 
are in the 8 to 10 ft range. Elsewhere, moderate or weaker winds 
and moderate seas are prevalent.

For the forecast W of 55W, the aforementioned front will weaken 
as it reaches from near 31N59W the Central Bahamas by early Mon, 
then dissipating from near 27N55W to 22N65W by early Tue. High 
pressure will build in its wake. Fresh to strong southerly winds 
and building seas are forecast offshore N Florida by Tue ahead of 
another possible cold front. That front may reach from near 31N76W
to 27N80W by early Thu, weakening and stalling from 31N69W to near
Fort Pierce, Florida by early Fri.
