from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient between 
high pressure across eastern Mexico and the eastern north 
Pacific monsoon trough is supporting strong gale- force winds, 
and seas to 20 ft, in the Tehuantepec region. Winds will start to
diminish Sun morning, falling below gale force Tue morning. 
Another gale force gap wind event is possible in Tehuantepec 
starting the middle of next week. 

Gulf of Papagayo Gale Warning: Fresh to strong NE to E gap winds
in the Gulf of Papagayo will reach near-gale to gale- force Sun 
night through Tue morning as an Arctic high pressure building 
over the eastern United States helps tighten the pressure 
gradient. Seas will peak near 12 ft with these winds. 

Please read the latest High Seas Forecast issued by the National
Hurricane Center at 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details.

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

The monsoon trough extends from 08N78W to 10N85W to 04N101W. The
ITCZ extends from 04N101W to beyond 07N140W. Scattered moderate 
convection is noted from 04N to 08N between 88W and 95W.

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

A Gale Warning is in effect for the Gulf of Tehuantepec through 
early next week. Please see the Special Features section above 
for more details.

Aside from the Gulf of Tehuantepec, the pressure gradient 
between surface ridging west of the Baja Peninsula and a surface 
trough over western Mexico is supporting moderate to locally fresh
NW winds in the Gulf of California. Seas are slight to moderate 
over these waters. Elsewhere, winds are moderate or weaker with 
moderate seas.

For the forecast aside from the Gulf of Tehuantepec, a set of NW
swell will impact the waters west of the Baja California 
peninsula late Sun night through Tue. 

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

A Gale Warning is expected for the Gulf of Papagayo starting Sun
night. Please see the Special Features section above for more 
details.

Fresh to strong winds prevail over the Papagayo region, as well
as in the Gulf of Panama. Otherwise, gentle to moderate winds 
and moderate seas prevail.

For the forecast, aside from the Gulf of Papagayo, a gale force 
gap wind event over the Gulf of Tehuantepec is producing rough to
very rough seas over the western Guatemala and El Salvador 
waters. Swell generated from the Gulf of Papagayo gap wind event 
will merge with this area to maintain rough and confused seas 
early next week. Fresh to strong northerly gap winds along with 
rough seas will impact the Gulf of Panama through Tue night.

...REMAINDER OF THE AREA...

A cold front is over the NW waters from 30N135W to 25.5N140W.
Scattered showers are in the vicinity of this front. The front
has ushered in a set of large NW swell, with seas in the 8 to 15
ft range behind the front. Elsewhere, surface ridging prevails 
across the waters north of 20N. The pressure gradient between the
ridge and lower pressure in the vicinity of the ITCZ is 
supporting moderate trades north of the ITCZ to near 18N and west
of about 128W. Elsewhere, moderate winds, and moderate seas in 
mixed swell, prevail.

For the forecast, the aforementioned cold front will weaken 
and dissipate through Sun. The very rough seas greater than 12 
ft will impact the waters N of 20N and W of 130W through Sun, 
with the rough seas greater than 8 ft spreading SE to cover the
waters NW of 04N140W to 30N120W by early Mon before starting to
subside below 8 ft. Seas with this swell will subside below 8 ft
by the middle of the week. Another set of large NW swell will 
move into the NW waters early Tue, and bring rough to very rough 
seas across the same general waters through the remainder of the 
week.
