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 0600 UTC surface analysis and satellite imagery through 
0900 UTC.

...SPECIAL FEATURES...

Gulf of America Gale Warning: A strong cold front will enter the 
NW Gulf waters early Mon. The front will move quickly 
southeastward, departing the basin Tue night. Fresh to near gale- 
force winds will follow the front, along with rough seas. Gale- 
force N winds and rough to very rough seas will develop off 
Tampico Mon afternoon and night. These winds and seas will reach 
the waters off Veracruz Mon night and persist until Tue night. 
Seas may peak around 18 ft off Veracruz Mon night into Tue. 
Conditions will improve from north to south by midweek.

Central Atlantic Significant Swell: A couple of cold fronts are
moving through the north central waters. The first cold front 
extends from 31N40W to 26N54W. The second cold front enters the 
waters near 31N57W to 28N69W to 31N78W. Large swell generated 
from the first cold front is generating very rough seas greater
than 12 ft over the forecast waters N of 27N between 41W and 55W.
Another set of large NW swell has entered the waters with the
second cold front, with very rough seas greater than 12 ft
covering the waters N of 29N east of 65W, and merging with the
very rough seas generated from the first front. The combined area
of very rough seas will shift eastward across the waters N of 24N.
Seas will peak at around 18 ft near 31N47W by early Tue. 

Please read the latest High Seas Forecast issued by the National 
Hurricane Center at website:

information.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 10N15W and continues 
to 06N17W. The ITCZ continues from 06N17W to 03N30W to 07N56W. 
Scattered moderate and isolated strong convection is noted from
02N to 06N between 11W and 22W. Scattered moderate convection is
noted within 60 nm either side of the ITCZ between 32W and 56W. 

...GULF OF AMERICA...

Please read the Special Features section above on an upcoming 
Gale Warning.

A surface trough is over the SW Gulf, while the remainder of the
Gulf is dominated by a 1019 mb high centered over the NE Gulf.
Light to gentle winds are over the NE Gulf, with moderate to
locally fresh winds prevailing elsewhere. Seas are in the 1-2 ft
range over the NE Gulf, and 2-4 ft elsewhere. 

For the forecast, a weak pressure gradient will support gentle to
moderate E to SE winds and slight to moderate seas across the
Gulf through late today. The next cold front is expected to enter
the northwest Gulf early Mon, followed by fresh to strong 
northerly winds and rough seas, except gale conditions are 
expected in the far west central and southwest Gulf by Mon 
afternoon. Winds and seas will diminish across the basin through 
mid week as high pressure builds over the region following the 
front. 

...CARIBBEAN SEA...

Moderate to fresh winds,a and seas of 6-8 ft prevail over the 
south central Caribbean. Moderate to fresh winds, and seas of 4-6 
ft are in the north central Caribbean. Moderate winds, and seas of
2-4 ft, prevail elsewhere. 

For the forecast, the pressure gradient between strong high 
pressure across the western Atlantic and the Colombian low will 
support fresh to strong winds off Colombia through mid week, with 
moderate to fresh trade winds elsewhere. A cold front will move 
through the Yucatan Channel Tue night, reach from central Cuba to 
Belize by late Wed, and from eastern Cuba to the Gulf of Honduras 
by late Thu. 

...ATLANTIC OCEAN...

See the Special Features section at the beginning for details on 
the ongoing significant swell.

A pair of cold fronts are moving through the northern waters. The
first cold front extends from 31N40W to 26N54W. Scattered moderate
and isolated strong convection, and gentle to moderate winds are
in the vicinity of this front. The second cold front enters the
waters near 31N57W to 28N69W to 31N78W. Scattered moderate and
isolated strong convection is within 60 nm east of the front.
Fresh to strong winds are within 60 nm east of the front, and 
north of the front. Aside from the very rough seas discussed in
the Special Features section above, rough seas greater than 8 ft
cover the waters N of a line from 30N70W to 22N55W to 30N28W.
Moderate to fresh winds, and seas of 6-8 ft, are found S of 12N
between 30W and 55W. Elsewhere, moderate or weaker winds, and
moderate seas prevail. 

For the forecast west of 55W, a cold front over the northern 
waters will move east of the area by early Mon, leaving a trailing
stationary front to dissipate along 21N. Strong to near- gale 
force winds and rough seas will follow this front. Large N swell 
will also follow this front, mixing with large swell already 
covering the area north of 22N and east of 70W. Another cold front
will move off the northeast Florida coast Mon night, and will 
reach from Bermuda to Jupiter Inlet, Florida by late Tue, from 
31N60W to central Cuba by late Wed, and from 31N55W to eastern 
Cuba by Thu night.
