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

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient between
high pressure over NE Mexico and lower pressure south of Mexico 
will continue to produce gale-force northerly winds in the Gulf 
of Tehuantepec region through early Fri afternoon. Thereafter, 
strong north to northeast gap winds will occur into early Sun. 
Rough to very rough seas will accompany these winds, with seas 
peaking to near 14 ft today. Seas are forecast to begin to 
gradually subside starting Thu and through the upcoming weekend.
Please read the latest High Seas Forecast issued by the National
Hurricane Center at the website- 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for details.

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

The monsoon trough axis extends from the coast of Costa Rica 
near 09N83W to 07N90W to 06N100W to 05N105W, where it transitions 
to the ITCZ to 07N110W to low pressure near 08N115W 1011 mb, and 
to 07N122W to 08N129W, resuming to the west of a trough at
08N132W and to beyond 08N140W. Scattered moderate convection is 
within 120 nm of the ITCZ between 111W and 116W, also within 60 
nm north of the between 95W and 100W and between 128W and 140W. 

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

Please read the Special Features section above for information 
on gale-force northerly gap winds in the Gulf of Tehuantepec.

A weak high pressure regime dominates the basin, supporting moderate
to locally fresh NW winds and seas of 5-7 ft in the offshore 
waters of Baja California. A relatively weak gradient will
support light to gentle winds and slight to moderate seas are 
found in the rest of the Mexican offshore waters and Gulf of 
California, excluding the Gulf of Tehuantepec.

For the forecast, aside from the ongoing gale-force winds in the
Gulf of Tehuantepec, high pressure over the eastern Pacific will
continue to support mainly moderate northwest to north winds and
moderate seas across the remainder of the Mexico offshore waters
this week. Winds will diminish this weekend. Long-period
northwest swell is forecast to enter the waters north of Punta 
Eugenia early next week, resulting in seas to near 10 ft. 
Meanwhile, winds may increase to strong force in the Gulf of 
California by Tue.

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

The pressure gradient related to strong high pressure of 1032 mb
centered in the southeastern United States continues to force 
strong to near gale-force northeast winds across the Gulf of 
Papagayo and downstream to 92W. Seas over these waters are 7-9 
ft. Moderate to fresh easterly winds extend downstream to 95W, 
and are also affecting the offshore waters of Honduras, El 
Salvador and Guatemala. Seas are 5 to 8 ft in the area 
described. The gale-force gap wind event in the Gulf of 
Tehuantepec is also boosting seas to 8 ft in the far offshore 
waters of Guatemala.

Farther south, an overnight ASCAT satellite data pass indicates 
gentle to moderate northwest west winds just south of the central
portion of Panama. Light and variable winds are elsewhere south 
of Panama to near 05N, where winds become mostly moderate in 
speeds and southwest in direction south of that latitude. Seas 
of 4 to 6 ft are with these winds. Otherwise, moderate or weaker 
winds and moderate seas are prevalent.

For the forecast, strong high pressure north of the area will 
continue to produce strong to locally near gale-force northeast 
winds in the Gulf of Papagayo into Thu. Locally rough seas in 
northeast swell associated with these winds will continue into 
Thu. Winds will remain fresh to locally strong into this weekend.
Farther west, rough seas induced by gale-force winds in the Gulf
of Tehuantepec will continue through early Fri. Moderate to 
locally fresh northeast winds will pulse across the remainder of 
the Central American waters through Thu. Otherwise, moderate, to 
at times, fresh south to southwest winds and moderate seas will 
remain south of the monsoon trough.

...REMAINDER OF THE AREA...Corrected

High pressure  well north of the area dominates the basin, 
forcing moderate to fresh easterly trade winds south of 20N and 
west of 130W. Seas over these waters are 8 to 10 ft in mixed
swell. Elsewhere, moderate or weaker winds and moderate seas are
evident.

For the forecast, moderate to rough seas will continue in the
western trade winds waters over the next few days due to high
pressure to the north. In the eastern waters, fresh to strong
northeast to east winds and rough seas will continue to spread 
downstream from the Gulf of Tehuantepec and Gulf of Papagayo over
the next day or so, diminishing late this week. A new set of
long-period northwest is forecast to enter the northwest part 
of the area this weekend. Otherwise, high pressure will dominate
the eastern Pacific, supporting moderate to locally fresh 
northeast to east winds and moderate seas through the rest of 
the week.
