...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient between 
high pressure over eastern Mexico and lower pressure south of 
the Gulf of Tehuantepec associated with the monsoon trough is
supporting N to NE gale-force winds across the Gulf of Tehuantepec
region tonight with seas to 9 ft. Winds are forecast to peak to 
40 kt on Mon with seas building up to 12 ft. Winds are forecast
to diminish below gale-force early Tue morning. Please see the 
latest NWS High Seas Forecast issued by the National Hurricane 
Center at website://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for 
more information.

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

The monsoon trough extends from NW Colombia near 09N75W to 
07N90W to 07N108W. The ITCZ continues from 07N108W to 10N125W to  
10N140W. Scattered moderate convection is N of 03N E of 83W, and 
from 07N to 14N W of 128W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Please see the Special Features section above for details on an
ongoing gale-force gap wind event in the Gulf of Tehuantepec.

Gale-force N to NE winds are ongoing in the Gulf of Tehuantepec 
region and are forecast to continue through Mon night. Strong to
near gale force winds will continue in this region Tue and 
diminish to fresh to strong Tue night. Strong to near gale-force
winds will resume Wed night and prevail through Fri. 

Moderate to locally fresh northerly winds are along the Gulf of 
California to the offshore waters of Jalisco. These winds will 
diminish Tue. Moderate to locally fresh NW winds will resume 
near the entrance of the Gulf Thu and prevail through Fr night. 

Otherwise, gentle to moderate northerly winds with seas to 5 ft
in N swell will diminish Tue.

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

Fresh to strong NE winds in the Papagayo region will continue 
through Fri night with seas building up to 9 ft. Moderate S to 
SW winds are expected S of the monsoon trough or S of 06N through
Fri night with seas to 5 ft in SW swell. Otherwise, moderate N 
to NE winds are forecast for the Gulf of Panama through the 
forecast period.

REMAINDER OF THE AREA...

High pressure prevails over the northern waters. The pressure 
gradient between this high pressure and lower pressures in the 
vicinity of the ITCZ is supporting moderate to fresh NE to E  
trades north of the ITCZ to near 24N and west of about 120W. 
Seas are 6-7 ft across this area. Gentle to moderate trades are 
elsewhere over the discussion waters with seas of mainly 4-6 ft.

For the forecast, the pressure gradient will continue weakening
through tonight as a front approaches the far northwest corner 
of the area. This will allow for the aforementioned fresh winds 
to diminish in coverage. The 6-8 ft seas will subside slightly to
5-7 ft. Mainly gentle to moderate east trades will continue 
elsewhere through early next week, except for pockets of fresh 
trades west of about 130W. After today, the seas of 5-7 ft will 
continue through early next week over the majority of the area, 
with the exception of the far western waters north of 15N and 
west of about 135W, where a set of northwest swell will bring 
seas of 8-9 ft to those waters.
