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 1200 UTC surface analysis and satellite imagery through
1632 UTC.

...SPECIAL FEATURES...

Heavy Rainfall in the NW Caribbean and SE Gulf of Mexico:
Abundant tropical moisture surging northward combined with mid
to upper level diffluent flow continue to generate showers and
thunderstorms across parts of the NW Caribbean, and portions of
the SW Caribbean. Dangerous lightning, strong gusty winds, rough
seas and low visibility are likely ongoing within this
convective activity over these areas, including the offshore
waters of E Honduras and Nicaragua. This convection will amplify
while it shifts towards the SE Gulf of Mexico and the Florida
Straits through at least Thu. Mariners should exercise caution.
Please refer to bulletins and forecasts from your local weather
forecast offices for detailed information.

...TROPICAL WAVES...

A tropical wave in the eastern Atlantic has been relocated and
is extending from 01N to 17N with axis near 20W. Scattered
moderate convection is from 05N to 07N between 17.5W and 22W.

A tropical wave in the eastern Atlantic has been relocate and is
extending S of 11N to inland Suriname with axis near 56.5W.
Scattered moderate isolated strong convection is from 07N to 11N
between 53W and 59W.

A tropical wave is in the south-central Caribbean Sea S of 12N to
inland W Venezuela with axis near 71W, moving westward at 10-15
kt. No deep convection is evident in the Caribbean waters in
association with this wave.

A tropical wave in the SW Caribbean Sea has been relocated with
axis extending S of 15N across Panama and into E Pac waters near
81W. Numerous moderate to strong convection is from 10N to 20N
between 75.5W and 83.5W.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 11N15W and continues
southwestward to 07N19W. The ITCZ extends from 07N22W to 04N41W
and to 08N55W. Aside from the convection associated with the
tropical waves, scattered moderate convection is from 02.5N to
09N between 24W and 52W.

...GULF OF MEXICO...

A weak pressure gradient persists across the Gulf of Mexico,
resulting in primarily moderate or weaker winds and slight seas.
A dry airmass continues to suppress the development of showers
and thunderstorms. Light concentration of smoke continue over
the western Gulf, including the Bay of Campeche, due to ongoing
agricultural fires, creating hazy conditions.

For the forecast, a weak pressure gradient will support mainly
gentle to moderate winds most of the forecast period. Moderate
to fresh S to SE winds will develop over the E half of the basin
toward the end of the week. Otherwise, hazy conditions due to
agricultural fires over Central America and Mexico will continue
for at least the next couple of days, reducing visibility to
around 3 nm at times, mainly over the SW Gulf.

...CARIBBEAN SEA...

Please read the Special Features section for information about
heavy rainfall in the NW Caribbean.

Broad subtropical ridge centered over the central Atlantic
extends into the E Caribbean Sea, maintaining fairly tranquil
weather conditions outside of the NW and SW Caribbean. The
pressure gradient between this ridge and lower pressures in
northern South America results in fresh to strong easterly trade
winds in the south-central Caribbean. Seas in these waters are 5-
7 ft. Moderate to fresh E to SE breezes and moderate seas are
occurring in the north-central, eastern and NW Caribbean.

For the forecast, scattered showers and thunderstorms are
expected across the NW Caribbean through Tue. Moderate to fresh
trades will prevail across the central and eastern Caribbean
through the forecast period, pulsing to locally strong winds at
night. Moderate to occasionally fresh SE winds are forecast for
the NW Caribbean most of the forecast period.

...ATLANTIC OCEAN...

A stationary front enters our area near 31N26W then continues
southwestward to 24N47W where it begins to dissipate to 21N56W.
Isolated light showers are found along this front. Broad ridging
continues to dominate much of the subtropical Atlantic,
sustaining moderate to locally fresh SW winds and seas of 3-5 ft
north of 27N and west of 65W, with the highest winds and seas
occurring off NE Florida. Moderate to locally fresh SE winds are
also noted across the offshore waters of Puerto Rico, Hispaniola
and southern Bahamas along with moderate seas to 5 ft. Farther
east, moderate to locally fresh NE winds and seas of 4-6 ft are
noted N of 15N off the coast of W Africa to 27W. Over the
tropical Atlantic, trades are moderate to fresh between 27W and
the Lesser Antilles. Elsewhere in the basin, moderate or weaker
winds and slight to moderate seas prevail.

For the forecast W of 55W, surface high pressure and associated
ridging will prevail across the region through Thu, then
gradually shift northward through the end of the week. Moderate
to fresh S to SW winds over the NE Florida offshore waters will
continue through Tue night, briefly reaching strong speeds N of
29N between 74W and 80W tonight and Tue evening. Elsewhere,
gentle to moderate winds are expected on either side of the
ridge, with light to gentle winds along the ridge axis.
