...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Building ridge over NE Mexico
supports fresh to strong northerly winds and rough seas across
the Gulf of Tehuantepec. Winds will further increase to gale 
force overnight tonight into early Mon, with seas building to 12 
to 14 ft on Mon night into early Tue. Gusty winds to near storm 
force may occur. These marine conditions are forecast to persist 
through early Tue morning. Seas generated from this gap wind 
event will spread well away from the Tehuantepec area, with seas 
8 ft or greater reaching as far south as 11N Mon night into Tue.

Hurricane Center at website:

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

A surface trough extends from 08N78W to 05N99W. The ITCZ 
stretches from 05N99W to 07N120W to beyond 05N140W. A second 
ITCZ is located south of the Equator and runs from 06S85W to 
02S127W. Scattered moderate convection is observed along surface
trough. Numerous moderate convection is evident south of 10N and
west of 115W.

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

Please refer to the Special Features section for details on a
developing Gulf of Tehuantepec Gale Warning.

A strengthening ridge over the southern United States is forcing
fresh to strong northerly winds and seas to 8 ft in the Gulf of 
Tehuantepec. Meanwhile, a weak ridge centered west of Baja
California supports moderate or weaker winds and moderate seas
across the offshore waters of the aforementioned peninsula.
Moderate or weaker winds and slight to moderate seas are found in
the Gulf of California waters. Elsewhere, light to gentle winds
and moderate seas in southerly swell prevail in the remaining
Mexican offshore waters.

For the forecast, other than the developing Gale Warning in the 
Gulf of Tehuantepec, gentle to moderate winds and slight seas 
will prevail in the Gulf of California through much of the week, 
pulsing to moderate to fresh in the central portion early week. 
Moderate to locally fresh NW winds and moderate seas are expected
off Baja California through the forecast period. However, winds 
may increase to strong N of Punta Eugenia Thu night through Fri 
night. Looking ahead, fresh to strong N winds may return to the 
Gulf of Tehuantepec by early Fri.

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

The subtropical ridge centered north of the basin supports mainly
moderate easterly trade winds across the Gulf of Papagayo region,
along with seas of 4-5 ft. Farther east, moderate N-NE winds and
moderate seas are present in the Gulf of Panama. Meanwhile, 
light to gentle winds and moderate seas dominate the remainder of
the offshore forecast waters. Some active convection is present 
offshore Colombia and Panama as described above.

For the forecast, fresh to strong gap winds are expected during the 
nighttime and early morning hours in the Papagayo region and 
downwind to about 90W through the forecast period. Moderate to 
locally fresh northerly winds are forecast in the Gulf of Panama 
through much of the week. A gap wind event in the Tehuantepec 
region will produce seas to 8 ft in the far offshore waters of 
Guatemala Mon night through Tue. Light to gentle winds and 
moderate seas will prevail elsewhere.

...REMAINDER OF THE AREA...

A cold front is approaching the far NW waters of the tropical
eastern Pacific. A few showers are noted ahead of this boundary.
Farther south, a deep upper level trough continues to produce 
abundant cloudiness and some showers over the western waters, 
especially N of 14N and W of 120W. At the surface, a weak high
pressure system over the northern waters dominates the remainder
of the tropical eastern Pacific. Moderate to locally fresh 
easterly winds are occurring north of the ITCZ and west of 110W.
Seas in these waters remain around 6 to 8 ft. Elsewhere, 
moderate or lighter winds and moderate seas are prevalent.

For the forecast, a cold front is forecast to reach 30N140W 
tonight, and extend from 30N137W to 24N140W by Mon morning. 
Gentle to moderate winds are forecast on either side of the 
front. Seas will briefly build to 9 ft behind the front Mon night
into Tue. High pressure will support moderate to locally fresh 
easterly winds and moderate to locally rough seas across the 
trade wind zone into the middle of the week, supporting seas to 
around 8 ft. Seas may build to around 8 ft in southerly swell 
near 03.4S by the end of the week.
