Tropical Weather Discussion for North America, Central America
Gulf of America, 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
0355 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic through the coast of Guinea
near 11N15W and continues southwestward to 03N30W. The ITCZ
extends from 03N30W to 00N45W. Scattered moderate convection is
observed south of 06N and east of 29W.

...GULF OF AMERICA...

The pressure gradient between an extensive ridge over the eastern
United States and lower pressures associated with a frontal
boundary that extends from the NW Atlantic to western Cuba
support fresh to strong easterly winds and rough seas over the SE
Gulf waters, including the Florida Straits. The strongest winds
and highest seas are found in the Florida Straits. Elsewhere,
moderate or weaker winds and moderate seas prevail.

For the forecast, fresh to locally strong NE to E winds and rough seas
will gradually diminish tonight in the SE Gulf. High pressure will
build across the Gulf, with a relatively weak pressure gradient
across the area. This will result in gentle to moderate SE winds
basin- wide by Wed night, then prevailing through late week.

...CARIBBEAN SEA...

Pockets of low-level moisture support isolated showers across the
Caribbean Sea. The presence of a frontal boundary just north of
the basin allows for a weak pressure gradient across the
Caribbean, supporting moderate to locally strong NE winds in the
lee of Cuba, Windward Passage and south-central Caribbean. This
was confirmed by a recent scatterometer satellite pass. Seas in
these waters are 3-5 ft. Elsewhere, moderate or lighter winds and
slight to moderate seas are prevalent.

For the forecast, weak Atlantic high pressure will continue N of the
basin and support a weaker than usual pressure gradient over the
Caribbean basin into the weekend. Fresh NE winds are expected
tonight through Wed night across the Windward Passage and south of
Cuba as a late-season cold front moves across Cuba, then
dissipates along the N coast of Hispaniola Wed night into Thu.
Tranquil marine conditions are expected across the entire basin
Fri through the weekend.

...ATLANTIC OCEAN...

A cold front extends from a gale-force low pressure in the NW
Atlantic to 31N58W and continues southwestward to the SE Bahamas
and central Cuba. A few showers and thunderstorms are noted ahead
of this boundary, especially north of 24N. Fresh to strong N-NE
winds and rough seas to 11 ft are occurring behind the front.
However, light to gentle winds and moderate seas are found under
the ridge off the SE United States, mainly north of 29N and west
of 74W.

Farther east, northerly swell associated with a storm-force low
pressure well north of the Azores supports rough seas over the far
NE Atlantic, especially north of 24N and east of 36W. Elsewhere, a
weak high pressure dominates sustaining moderate or weaker winds
and moderate seas.

For the forecast west of 55W, fresh to strong N to NE winds and
rough seas will continue to follow the aforementioned front as it
moves eastward through Wed night. Conditions will gradually
improve late this week as the front weakens and eventually stalls
Fri over the SE waters. High pressure will settle in between
northeast Florida and Bermuda for the end of the week, bringing
tranquil conditions to area waters through the weekend.
