Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
2030 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Gale-force northerly gap winds
will generally continue into Sat across the Gulf of Tehuantepec,
and despite a brief lull Sat afternoon, high pressure will 
strengthen over eastern Mexico Sat night and prolong gales into 
Sun. Seas will peak Sat morning and again Sun morning at around 
14 ft. Later on Sun, high pressure will move east and weaken, and
marine conditions will improve. 

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

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

A surface trough extends from 10N77W to 06N86W to 04N97W. The 
ITCZ extends from 04N97W to 06N111W to 02N131W. Scattered 
moderate to strong convection is noted from 00N to 08N east of 
82W and from 01N to 10N between 82W and 91W. Scattered moderate 
convection is noted from 02N to 04N between 91W and 100W and 
from 02N to 12N between 105W and 111W.
 
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Please see the Special Features section for information on a gale
warning in effect for the Gulf of Tehuantepec.

Otherwise, a weak pressure gradient is leading to mainly gentle
winds over the waters, aside from some moderate NW to N winds
offshore Baja California Norte, on the west side of a surface 
trough axis located over Baja California. Seas are generally 5 to
7 ft, in NW swell offshore Baja California, and SW swell for the
remainder of the waters. In the Gulf of California, seas are 3 ft
or less.

For the forecast, moderate to large NW swell will impact the 
Baja California waters this weekend, then subside early next 
week. Looking ahead, gale-force gap winds may redevelop in the 
Gulf of Tehunatepec Tue night into Wed . 

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

Fresh to locally strong NE to E winds are across the Papagayo 
region, where seas are 6 to 8 ft. Moderate N winds are in the 
Gulf of Panama. Winds are light to gentle elsewhere. Seas are 5 
to 8 ft, in moderate to large S to SW swell. Scattered moderate 
to isolated strong convection prevails across the waters north 
of the equator to 10N, and east of 91W to the coasts of Costa 
Rica, Panama and Colombia.

For the forecast, high pressure extending southward across the 
western Caribbean will prevail through Mon night, leading to 
pulsing fresh to strong NE to E gap winds, and locally rough 
seas, across the Papagayo region. Locally fresh winds will pulse 
during this time in the Gulf of Panama. Large N swell from Gulf 
of Tehuantepec gales will propagate into the waters offshore 
Guatemala through the weekend. Moderate SW swell impacting the 
regional waters will subside into the weekend. 

...REMAINDER OF THE AREA....

A weak cold front is stalling from around 30N133W to 25N140W.
Behind the front, fresh to locally strong NE winds and seas of 8
to 11 ft prevail. Some moderate to locally fresh trades are 
found N of the ITCZ extending N to around 20N, W of 125W. 
Otherwise, winds are moderate or weaker. E of 115W, seas are 8 
to 10 ft in merging SW and NW swell, and 5 to 7 ft elsewhere in 
the waters.

For the forecast, the cross-equatorial swell over the waters 
south of 20N will gradually subside from west to east through 
Sat. Gulf of Tehunatepec northerly gales will send N to NE swell
well southwest of the source region toward the central waters 
mixing with the aforementioned SW swell through the weekend. The 
cold front in the far NW waters will meander through the weekend 
before dissipating, producing fresh to locally strong NE winds 
and large NW swell behind it. That swell will induce wave heights
to 7 to 10 ft, mainly north of 24N or so through the weekend. 
Winds will freshen west of 130W through the weekend as high 
pressure builds across the region in the wake of the dissipating
front.
