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 
0830 UTC.

...TROPICAL WAVES...

An eastern Atlantic tropical wave has its axis near 44W from 03N 
to 19N, moving westward at about 10 to 15 kt. Scattered moderate
and isolated strong convection is noted from 04N to 10N between
43W and 48W. 

A central Atlantic tropical wave has its axis near 56W, moving 
westward near 10 to 15 kt. Scattered moderate convection is noted
from 11N to 17N between 52W and 57W. 

A central Caribbean tropical wave has its axis near 78W, south of
19N. It is moving westward at 10 to 15 kt. Scattered moderate 
convection is noted along the wave axis S of 12N.

...MONSOON TROUGH/ITCZ...

The monsoon trough enters the Atlantic near 19N16W, and continues
southwestward to 09N27W. The ITCZ continues from 09N27W to 
07N40W. It resumes near 07N41W to 06N49W. Scattered showers are 
noted along and south of the monsoon trough. Scattered moderate 
and isolated strong convection is noted from 07N to 14N between
14W and 20W, and from 05N to 08N between 26N and 32W. 
 
...GULF OF AMERICA...

A cold front extends across the eastern waters from central
Florida to Mississippi. Isolated showers and thunderstorms are in
the vicinity of the front. A surface trough has moved westward off
the Yucatan peninsula into the SW Gulf. Gentle to moderate winds
are in the vicinity of the trough. Light to gentle winds are over
the SE Gulf. Gentle winds and slight seas are noted elsewhere. 

For the forecast, weak high pressure will persist across the Gulf
basin through the period, producing a weak pressure gradient.
This will support mostly light to gentle winds and slight seas
over much of the waters. Winds will pulse to fresh with moderate
seas off the western Yucatan Peninsula during the evenings due
to a diurnal surface trough moving westward from the peninsula
each night.  

...CARIBBEAN SEA...

The pressure gradient between high pressure over the western 
Atlantic and the Colombian low is supporting fresh to strong 
trades along with moderate seas over the south- central Caribbean.
Moderate to fresh trades and moderate are over the rest of basin,
with the exception of the northwestern waters, where light to 
gentle winds are noted.

For the forecast, the western Atlantic ridge extends E to W along
about 26N to the NW Bahamas. The pressure gradient between the
ridge and the Colombian low will support strong winds, locally to
near- gale force, through Wed night before diminishing modestly 
through Fri. Rough seas will develop over these waters with the 
persistent strong winds. Elsewhere, moderate or weaker winds and 
slight to moderate seas will prevail. Large easterly swell will 
accompany a tropical wave into the Tropical N Atlantic waters 
early Wed through Thu morning. 

...ATLANTIC OCEAN...

A stationary front extends from near 31N69W to central Florida.
Scattered moderate convection is in the vicinity of the front.
High pressure dominates the remainder of the waters N of 20N,
anchored by a 1027 mb high centered near 33N31W. Fresh to strong
winds are noted N of 20N and E of 30W. Moderate to fresh winds
prevail S of 22N and E of 60W. Gentle to moderate winds generally
prevail elsewhere. Seas are in the 7-9 ft range from 15N to 28N
and E of 45W. Mainly moderate seas dominate the remainder of the
discussion waters. 

For the forecast west of 55W, weak high pressure extending from 
the central Atlantic westward along about 26N to the NW Bahamas 
will gradually shift northeastward and strengthen through mid 
week. This pattern will support moderate or weaker winds and 
moderate seas today, then moderate to fresh winds S of 21N tonight
through Thu. A stationary front will linger near 31N through mid 
week before lifting northward. Showers and thunderstorms will 
remain active across these northern waters W of 60W through 
tonight.
