...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Building ridge over NE Mexico
supports strong to gale-force northerly winds and rough seas to
12 ft across the Gulf of Tehuantepec. Gale-force winds will continue
through early Tue morning with seas building to 14 ft tonight 
into early Tue. Gusty winds to near storm force may occur. 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 tonight into Tue. Winds and seas will quickly 
diminish Tue.

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

A surface trough extends from 07N78W to 05N101W. The ITCZ 
stretches from 05N101W 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 present south of 10N and
west of 115W.

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

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

Aside from the Gale Warning in the Gulf of Tehuantepec, a weak 
ridge positioned near 31N128W supports moderate or weaker winds 
and moderate seas across the offshore waters of Baja California.
Gentle to locally moderate 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, 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. Gentle to moderate winds 
and slight seas will prevail in the Gulf of California through 
much of the week. Looking ahead, fresh to strong N winds may 
return to the Gulf of Tehuantepec by late Thu to early Fri.

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

A building ridge over the NW Gulf of America forces fresh to 
locally strong easterly winds across the Gulf of Papagayo region.
Seas in these waters are 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. The convection
previously near Colombia and Panama has decreased.

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 9 ft in the far offshore waters of 
Guatemala tonight through Tue. Light to gentle winds and 
moderate seas will prevail elsewhere.

...REMAINDER OF THE AREA...

A cold front is near the far NW waters of the tropical eastern 
Pacific. A few weak 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 15N and W of 120W. At the surface, a weak high 
pressure system over the northern waters dominates the remainder 
of the basin. Moderate to locally fresh easterly winds are 
occurring north of the ITCZ and west of 110W. Seas in these 
waters remain around 5 to 8 ft. Elsewhere, moderate or lighter 
winds and moderate seas are prevalent.

For the forecast, a cold front is near 30N140W, and will extend 
from 30N137W to 24N140W by late this morning. Gentle to moderate 
winds are forecast on either side of the front. Seas will briefly
build to 9 ft behind the front this afternoon 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.
