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
1930 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: the pressure gradient between 
high pressure across eastern Mexico and the equatorial trough is
supporting gale-force N-NE winds in the Gulf of Tehuantepec. 
Seas are 10-12 ft across this region. The gale force winds are 
forecast to continue into early Sat before diminishing.

Please read the latest HIGH SEAS FORECAST issued by the National
Hurricane Center at website - 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more 
information. 

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

A surface trough extends from 08N77W to 05N90W. The ITCZ extends
from 05N90W to 01N140W. Scattered moderate convection is noted 
from 05N to 08N between 115W and 127W.

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

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

Aside from the Gulf of Tehuantepec, a weak pressure gradient is 
generating light to gentle winds, except locally moderate off
Cabo San Lucas. Moderate seas prevail over the open waters, with
slight seas in the Gulf of California.

For the forecast, aside from the Gulf of Tehuantepec gale 
warning, moderate to fresh NW winds will dominate offshore Baja
California, with light to gentle winds elsewhere. Moderate seas
will generally prevail, with slight seas in the Gulf of
California. Long period N swell will arrive Sun offshore Baja
California Norte, and this may lead to rough seas there Sun night
into early next week. 

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

Moderate gap winds are ongoing in the Gulf of Papagayo and Gulf
of Panama, with light to gentle winds elsewhere. Seas are 3 to 5
ft, except for 6 to 8 ft seas will offshore Guatemala due to
gale-force gap winds N of the region in the Gulf of Tehuantepec. 

For the forecast, large N swell generated by the gale-force gap 
winds in the Gulf of Tehuantepec will impact the offshore waters 
of Guatemala into Sat. Fresh to strong winds will pulse nightly 
in the Gulf of Papagayo. Moderate to locally fresh winds will 
pulse nightly in the Gulf of Panama. Gentle breezes and moderate
seas will prevail elsewhere. 

...REMAINDER OF THE AREA...

The pressure gradient between high pressure centered N of the
area and the ITCZ is leading to moderate trades from the equator
to 15N, with gentle trades to the S. Dominated by the ridge,
waters N of 15Z are experiencing mainly gentle anticyclonic
winds. Seas through the basin are mainly 4 to 6 ft, except for
some locally rough seas N and E of 10N99W, where swell from gales
in the Gulf of Tehuantepec are propagating. 

For the forecast, moderate or weaker winds and moderate seas 
will generally prevail across the region into the start of next
week. N swell will build just S of 30N from off Baja California 
Norte Sun, leading to rough seas into Mon.
