from the Equator to 30N, between 120W and 140W. The following

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Building ridge across the 
eastern slopes of the Sierra Madre Mountains in Mexico will
force the next gap wind event in the Gulf of Tehuantepec. Winds 
are forecast to increase to 20 to 30 kt, with seas building to 8 
ft by tonight. Then, winds will further increase to gale force 
by Mon morning, with seas building to 12 or 13 ft on Mon night. 
Gusty winds to near storm force may occur. These marine 
conditions are forecast to persist through 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.

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

A surface trough extends from 08N83W to 06N98W. The ITCZ 
stretches from 06N98W to 06N120W to beyond 04N140W. A second 
ITCZ is located south of the Equator and runs from 08S87W to 
beyond 05S140W. Scattered moderate convection is present from 
01N to 08N and west of 120W.

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

A recent scatterometer satellite pass indicate that the strong
ridge over the western United States forces moderate to locally
fresh NW winds across the offshore waters of Baja California, 
especially north of Cabo San Lazaro. Seas in these waters are 6-8
ft. Gentle to moderate NW winds and seas of 2-5 ft are evident 
in the Gulf of California. In the remainder of the Mexican 
offshore waters, including the Gulf of Tehuantepec, light to 
gentle winds and moderate seas in south swell prevail.

For the forecast, a Gale Warning is in effect for the Gulf of
Tehuantepec. Please, see the Special Features section for more 
details. Meanwhile, NW swell producing locally rough seas off 
Baja California Norte will diminish by this morning. Gentle to 
moderate winds and slight seas will prevail in the Gulf of 
California through midweek next 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 north of Punta Eugenia Thu night.

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

High pressure north of the Caribbean is supporting fresh to
locally strong easterly trade winds across the Gulf of Papagayo 
region. Seas in these waters are 4-6 ft. Farther east, moderate 
to locally fresh northerly 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.

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 89W through the forecast period. Moderate to 
locally fresh northerly winds are forecast in the Gulf of Panama 
through at least midweek next 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 night. Light to gentle
winds and moderate seas will prevail elsewhere.

...REMAINDER OF THE AREA...

A deep upper level trough and a weak surface trough combine to
produce abundant cloudiness and some showers over the western
waters, especially north of 17N and west of 123W. At the 
surface, a 1022 mb high pressure near 32N130W, wedged between 
two low pressure systems, dominates the remainder of the tropical
eastern Pacific. A recent scatterometer satellite pass captured
moderate to fresh easterly winds 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, ridging will support moderate to locally fresh
easterly winds and moderate to locally rough seas across the 
trade wind zone into the middle of next week. 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.
