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.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends from the coast of Senegal near 13N17W 
to 03N24W. The ITCZ continues from 03N24W to 00N33W to 01S46W. 
Scattered moderate convection is observed over the offshore waters
of Liberia and Sierra Leone and from 04S to 05N between 35W and
51W.

GULF OF MEXICO...

A former cold front has stalled along the northern gulf coastal
waters from Panama City to SE Louisiana to Port Lavaca, Texas. The
remainder basin is under the influence of a weak surface ridge
anchored by a 1014 mb high near 23N87W. This is supporting light
to gentle variable winds across the central basin. The pressure
gradient between the ridge and low pressure along Mexico, supports
moderate to fresh SE winds W of 95W and winds of the same speed
off the coast of the Yucatan Peninsula. In the far NE gulf, the
pressure gradient between the front and the ridge supports fresh
to locally strong SW to W winds. Seas basin-wide are 3 to 4 ft,
except to 5 ft in the Florida Big Bend region. 

For the forecast, high pressure will build across the area and 
become centered over the eastern Gulf through Wed. The high 
pressure will then reform over the NE Gulf through Sat night. 
Fresh winds will pulse across the Bay of Campeche each night 
during the forecast period. 

CARIBBEAN SEA...

A stationary front extends from central Cuba SW to the Cayman
Islands to NE Honduras adjacent waters. Isolated showers are ahead
of the front reaching as far as the Windward Passage. Winds in the
NW Caribbean are mainly light to gentle, except for moderate
trades across Belize and western Honduras offshore waters. In the
SW Caribbean, the E Pacific extension of the monsoon trough
supports scattered showers in the Costa Rica and Nicaragua
offshore waters. Otherwise, the pressure gradient between lower
pressure over northern S America and surface ridging NNE of the
region supports fresh to strong winds in the south-central and SE
basin and gentle to moderate trades in the NE Caribbean. Seas are
5 to 6 ft in the SE regional waters and 3 to 4 ft elsewhere. 

For the forecast, the stationary front over the NW Caribbean will 
dissipate early Tue. Fresh to strong winds will develop offshore 
of Colombia tonight and continue through the rest of the week. By 
late Thu, similar winds will be over most of the central and 
eastern Caribbean lasting through late Sat. 

ATLANTIC OCEAN...

A cold front extends from 31N67W to 25N74W, where it transitions 
to a stationary front to central Cuba. Another cold front extends
from 31N73W to near the NW Bahamas. 

For the forecast W of 55W, fresh to strong southwest winds ahead 
of the front N of 28N will diminish early this evening. The front 
will gradually weaken and dissipate on Tue as it approaches the 
eastern part of the area. The front extending to the NW Bahamas will
move across the rest of the northern waters through Wed while 
weakening. A couple of more cold fronts will move across the area 
through the rest of the forecast period while weakening. The main 
impacts to winds and seas from these fronts are expected to be N 
and NE of the Bahamas.
