Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0350 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A surface trough extends from 06N85W to 03N100W to 02N110W. 
The ITCZ continues from 02N110W to 04N130W to beyond 03N140W. 
Scattered moderate convection is noted from 03N to 11N between
123W and 140W, and from 02N to 07N E of 91W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong high pressure of 1037 mb located well NW of the area near
38N137W extends a ridge southeastward towards the offshore waters
of Baja California. The pressure gradient between this ridge and
a meandering surface trough over the Gulf of California is 
producing moderate to fresh NW to N winds offshore the Baja 
California Norte waters. Seas are 4 to 7 ft within these winds S
of Punta Eugenia, and 7 to 11 ft in NW swell N of Punta Eugenia.
Mainly gentle to locally moderate winds with slight seas are 
across the Gulf of California S of 30N while fresh NW winds are
ongoing N of 30N. Light to gentle winds and slight to moderate
seas are ongoing elsewhere over the Mexican offshore waters. 

For the forecast, strong high pressure NW of the forecast region
will continue to support moderate to fresh NW to N winds across 
the offshore forecast waters of Baja California Norte through 
Fri. Rough seas in long-period NW swell associated with these 
winds will gradually decay through Sat evening. Weak low pressure
is expected to form just offshore Baja California Norte Fri 
through Sat, then shift slowly eastward into early next week. 
This will relax the pressure gradient over the offshore waters of
Baja California, leading to improving marine conditions through 
the weekend. Gentle to locally moderate winds and moderate seas, 
in SW swell, are expected in the Gulf of Tehuantepec through the 
forecast period.

....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...

Fresh to strong NE to E winds are across the Gulf of Papagayo 
and downwind to approximately 88W. Seas are 4 to 5 ft within 
these winds. In the Gulf of Panama, moderate northerly winds and
seas to 4 ft prevail. Elsewhere, winds are light to gentle with 
slight to moderate seas in SW swell. 

For the forecast, pulsing fresh to strong winds are expected in 
the Papagayo region through Tue night as high pressure remains N 
of the region. Gentle to locally moderate N winds are forecast in
the Gulf of Panama. Mainly light to gentle winds will prevail 
elsewhere through Tue night. Looking ahead, significant cross- 
equatorial SW swell is expected to briefly reach the offshore 
waters between Ecuador and the Galapagos Islands late on Mon, 
building seas to around 8 ft.. 

...REMAINDER OF THE AREA...

Strong high pressure of 1037 mb centered NW of the region near 
38N137W extends a ridge across most of the forecast waters N of 
18N and W of 115W. Under the influence of this system, fresh to 
strong N to NE winds prevail N of 06N and W of 120W. Seas of 8 
to 12 ft are within these winds, with the highest seas N of 26N 
between 120W and 130. Elsewhere, winds are moderate or weaker. 
Seas through the remainder of the open waters are 4 to 7 ft in 
mixed swell.

For the forecast, the strong high pressure will continue to 
dominate the subtropical waters through Fri night, supporting 
fresh to strong N to NE winds and rough seas. Looking ahead, a 
low pressure is forecast to develop and linger near Baja 
California Norte Fri through Sat, then drift slowly eastward into
early next week. During this same period, the high pressure will
slowly move westward and weaken. As a result, marine conditions 
are expected to improve as the pressure gradient relaxes across 
the forecast waters Sat through Mon.
