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 
0500 UTC.

...SPECIAL FEATURE...

East Atlantic Gale Warning: 
Meteo-France has issued Gale Warnings for the marine zones of
Agadir through 14/00Z and Tarfaya through 13/12Z. Please refer to
the Meteo-France High Seas Forecast product, listed on the 
website at https://wwmiws.wmo.int. for more information.

...MONSOON TROUGH/ITCZ...

A monsoon trough enters the Atlantic near the coastal border of
Senegal and Guinea-Bissau, then reaches southwestward to near
05N20W. An ITCZ continues from 05N20W across 00N30W to near Sao
Luis, Brazil. Widely scattered to scattered moderate convection 
is present up to 260 nm along either side of the ITCZ.

...GULF OF AMERICA...

A surface ridge extends southwestward from a 1026 nm high over the
Florida Big Bend area to near Tampico, Mexico. Thick cirrus from 
deep convection at northeastern Mexico is being carried across the
northwestern Gulf by upper-level winds. Fresh to strong NE to E
winds and seas at 5 to 7 ft are present at the southeastern Gulf
and eastern Bay of Campeche, including the Florida Straits. Light
to gentle winds and 1 to 3 ft seas are noted off the Florida Big
Bend area. Gentle to moderate with locally fresh E to SE winds 
and seas of 3 to 5 ft prevail for the rest of the Gulf.

For the forecast, the high and associated ridge will maintain 
moderate to fresh E to SE winds and mostly moderate seas through 
Fri. Expect stronger winds to pulse across the southeastern Gulf,
including the Florida Straits, through the early part of the 
week, and off the Yucatan Peninsula mainly at night through mid 
week.

...CARIBBEAN SEA...

A robust trade-wind pattern persists across much of the Caribbean
Sea. The southwestern end of a surface trough is triggering
scattered showers and isolated thunderstorms near Hispaniola and
the Mona Passage. Strong to near-gale NE winds and seas at 8 to 9
ft are present off northwestern Colombia. Fresh to strong NE winds
with 6 to 8 ft seas exist for the rest fo the south-central basin.
Fresh to strong NE winds and seas of 5 to 7 ft dominate waters
near the Windward Passage and lee of Cuba. Gentle to moderate with
locally fresh NE to E winds and 3 to 6 ft seas prevail elsewhere
in the Caribbean Sea.

For the forecast, high pressure over the western Atlantic will 
maintain fresh to strong E winds and rough seas over the south- 
central portion of the basin and near Colombia through the early 
part of the week. Fresh to strong NE winds and moderate seas will
prevail south of Cuba, in the Windward Passage, and south of 
Hispaniola through most of the week. Winds and seas will diminish 
late in the week. 

...ATLANTIC OCEAN...

Please read the Special Features section about Gale Warnings off 
Morocco.

A cold front extends southwestward from the north-central Atlantic
across 31N54W to near 29N56W, continues as a warm front to a 1018
mb low at 27N58W. It then becomes a stationary front and continue
southwestward through a 1016 mb low at 25N63W to the northern
coast of Hispaniola. Scattered moderate convection is occurring 
up to 110 nm northwest, and 170 nm southeast of these features. 
Convergent trade winds are causing scattered heavy showers near 
and north of the Amazon River Delta. Refer to the Monsoon 
Trough/ITCZ section at the beginning for additional convection in 
the Atlantic Basin.

Fresh to strong NE winds and seas of 8 to 11 ft are found near and
behind the aforementioned frontal boundary, except moderate to
locally fresh E winds and 6 to 7 ft seas off northeastern and
central Florida. To the east, gentle to moderate E to SE winds and
seas at 5 to 7 ft in moderate E swell exist north of 18N between 
35W and the frontal boundary. For the remainder of the Atlantic 
Basin west of 35W, moderate to fresh NE to ESE winds and 6 to 8 ft
seas in mixed moderate swells prevail.

For the forecast west of 55W, the frontal boundary will dissipate
through the early part of the week. Fresh to strong NE winds and 
rough seas will persist west of the front mainly south of 27N 
through mid week, then diminishing through Fri.
