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
1700 UTC.

...MONSOON TROUGH/ITCZ...

The monsoon trough extends off the coast of Africa near 10N14W
to 04N17W. The ITCZ continues from 04N17W to 01N35W to 01N50W.
Scattered moderate isolated strong convection is noted south of
the monsoon trough from 00N to 06N between 05W and 20W.
Scattered moderate convection is noted within 120 nm north of
the ITCZ between 20W and 40W.

...GULF OF MEXICO...

A cold front extends from Fort Myers, Florida to the eastern
Gulf where it transitions to stationary and continues to the
southwest Gulf. A 1025 mb high pressure center over Mississippi
allows for fresh NE to E winds following the front with moderate
E winds in the NW Gulf and gentle to moderate NE flow in the Bay
of Campeche. Moderate seas remain behind the front with seas
near 8 ft noted in the far SW Gulf.

For the forecast, the front will remain stalled over the SE Gulf
tonight, then lift north as a weak warm front into Mon night,
before dissipating. Another cold front will move off the Texas
coast Tue. Ahead of the front, widespread strong southerly winds
can be expected for the start of next week. Near gale conditions
is possible Mon night into Tue offshore the Texas coast.

...CARIBBEAN SEA...

Fresh to strong E winds and rough seas continue over the central
and eastern Caribbean sea today due to the pressure gradient
between high pressure over the tropical N Atlantic and lower
pressure over Colombia. The strongest winds are within 90 nm of
the coast of Colombia with seas reaching 12 ft. Over the western
Caribbean, gentle to moderate winds prevail with 3 to 5 ft seas.

For the forecast, high pressure north of the area will support
mainly fresh trade winds along with large trade-wind swell
across the Tropical Atlantic forecast zones through the forecast
period. Fresh to strong winds will prevail across the central and
eastern Caribbean during this time.

...ATLANTIC OCEAN...

A cold front enters our area of responsibility near 31N77W and
extends SW to Fort Pierce, Florida. Recent scatterometer data
reveals fresh ENE winds behind the front with gentle to moderate
southerly winds ahead of it. Seas remain 3 to 5 ft. Scatterometer
also notes gentle SE winds over the Bahamas where seas are 3 to 5
ft and moderate E winds north of Puerto Rico and Hispaniola where
seas are 6 to 8 ft.

Farther east, a broad area of high pressure continues over the
tropical N Atlantic. Scatterometer data from this morning found
light to gentle winds generally north of 22N and west of 35W.
Moderate NE winds are east of 35W including over the Canary
Islands. Fresh to strong NE winds prevail south of 22N. Mainly
moderate seas are north of 20N and west of 45W. Rough seas in E
swell are south of 20N between 50W and the Lesser Antilles. Seas
east of 40W and north of 15N are 10 to 12 ft in N swell.

For the forecast W of 65W, fresh winds will pulse to strong
nightly early this week offshore Hispaniola. The cold front will
continue to move east, becoming oriented along 25N Tue, then
stalling. Strong NW winds are likely to follow this front along
30N. Strong S flow may set up offshore FL by the middle of the
week, ahead of the next cold front.
