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 1800 UTC surface analysis and satellite imagery through
2200 UTC.

...SPECIAL FEATURES...

East Atlantic Gale Warning: Meteo-France has issued a Gale 
Warning along with rough to very rough seas for their AGADIR 
Marine Zone through 23/0600 UTC. Please see the latest HIGH SEAS 
FORECAST and WARNING issued by Meteo-France at website:
https://wwmiws.wmo.int for more information.

...MONSOON TROUGH/ITCZ... 

The monsoon trough axis enters the Atlantic along the coast of
Guinea near 10N15W, and continues southwestward to 04N20W, where
it transitions to the ITCZ south of the Equator reaching to near
the coast of Brazil at 02S43W. Scattered moderate to isolated 
strong convection is seen from 00N-03N between 21W-24W.

...GULF OF AMERICA...
 
High pressure ridging extends along the N Gulf promoting gentle
to moderate SE winds this afternoon with seas 3-5 ft. No
significant deep convection is occurring today.

For the forecast, the high pressure centered NE of the area will
bring mainly moderate SE winds and relatively tranquil marine 
conditions to the northern half of the basin through the week. 
The southern Gulf will experience fresh east to southeast winds, 
pulsing to strong off the NW Yucatan Peninsula each night as a 
diurnal trough affects the waters. A similar pattern should 
prevail over the weekend.

...CARIBBEAN SEA... 

The pressure gradient between the Bermuda High north of the area
to a 1010 mb Colombian low is forcing fresh to strong trades over
the S Central Caribbean and over the Windward Passage. A surface
trough just east of the Lesser Antilles is causing the trades to
only be gentle over the E Caribbean. Seas are 7-9 ft over the SW
Caribbean and 4-6 ft elsewhere. No significant deep convection is
occurring this afternoon over the Caribbean.

For the forecast, the high pressure north of the basin 
will support pulsing fresh to strong NE winds across the central 
and western Caribbean through tonight. The high will then shift 
eastward which will loosen the pressure gradient and diminish 
winds Wed afternoon through late week. Moderate northerly swell 
impacting the Mona passage will gradually subside through 
tonight. Moderate winds and slight to moderate seas will then 
prevail over the weekend.

...ATLANTIC OCEAN...

Please see the Special Features section above for information on a
Gale Warning issued in the far eastern Atlantic.

A 1010 mb surface low near 24N60W is situated along a north-
south oriented surface trough along 60W. Additionally, a
dissipating stationary front is situation north of the low from
27N69W to 31N54W. A tight pressure gradient between the low and 
a 1025 mb Bermuda High centered near 37N60W is causing fresh to 
strong winds and seas 8-10 ft from 25N-31N between 55W-67W. 
Scattered moderate convection is located from 25N-28N between 
53W-60W. Elsewhere west of 20W, the trades are gentle to 
moderate. The seas from 18N-25N east of 32N are 8-9 ft in mixed 
NE wind waves and N swell. Elsewhere seas are 5-7 ft in mixed 
swell.

For the forecast west of 55W, a pressure gradient between the 
surface trough and the subtropical ridge along 35N will continue 
to support fresh to strong E to NE winds and rough seas over 
Atlantic waters E of 70W and N of 23N through Wed. The trough 
will gradually weaken later this week as it moves slowly 
westward, loosening the pressure gradient and leading to 
improving marine conditions for the end of the week.
