...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Strong high pressure north of
the area will continue to support strong to gale-force N winds
through at least Sat morning. Winds may diminish below gale-force
in the afternoon and evening hours. Thereafter, strong N-NE gap 
winds will occur into early Sun. Rough seas will persist into the
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 extends from the coast of Costa Rica near 
08N82W to 06N100W and to 07N118W. The ITCZ stretches from 07N118W and
to beyond 08N140W. Scattered moderate convection is present
within 120 nm on both sides of the monsoon trough and ITCZ.

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

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

A 1026 mb high pressure system centered near 33N130W continues to
maintain moderate to locally fresh NW winds across the offshore
waters of Baja California. This was confirmed by a recent
scatterometer satellite pass. Seas in these waters are 5-7 ft.
Gentle to moderate NW-N winds are found in the central and
southern Gulf of California, along with seas of 2-4 ft. Light to
gentle winds and slight seas prevail in the northern Gulf waters.

Elsewhere in the Mexican offshore waters, excluding the Gulf of
Tehuantepec, moderate or weaker winds moderate seas are prevalent.

For the forecast, aside from the ongoing gale-force winds in the
Gulf of Tehuantepec region, high pressure over the eastern 
Pacific will continue to support mainly moderate NW-N winds and 
moderate seas across the remainder of the Mexico offshore waters 
for the rest of the week. Winds will diminish this weekend. Meanwhile,
winds may increase to strong along the entire length of the Gulf
of California Mon night into Tue, possibly reaching gale-force 
in the northern Gulf waters.

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

A 1025 mb high pressure system situated over northern Florida 
supports fresh to strong NE winds across the Gulf of Papagayo 
region and downstream waters to 90W. Seas in these waters are 
6-8 ft. Farther south, moderate S-SW winds and seas of 4-6 ft 
are occurring south of the monsoon trough. Elsewhere, light to 
gentle winds and slight to moderate seas are evident.

For the forecast, strong high pressure north of the area will 
support fresh NE winds in the Papagayo region, pulsing to strong
speeds at night, through the weekend. Locally rough seas in NE 
swell associated with these winds may occur today. Farther west,
rough seas induced by gale-force winds in the Gulf of 
Tehuantepec will continue through early Fri. Moderate to locally 
fresh NE winds will pulse across the remainder of the Central 
American waters through Thu. Otherwise, light to gentle southwest
to west winds along with moderate seas are expected south of the
monsoon trough going into the weekend, with the exception of 
moderate southwest winds and moderate seas offshore Colombia 
south of 05N through Sat.

...REMAINDER OF THE AREA...

A 1026 mb high pressure system positioned north of the area 
continues to support moderate to fresh easterly trade winds 
south of 27N to the ITCZ. Seas in these waters are 6-10 ft, with
the highest seas occurring in the westernmost trade waters. Elsewhere,
moderate or weaker winds and moderate seas prevail.

For the forecast, little change is expected in the western part 
of the area through the end of the week. In the eastern waters, 
fresh to locally strong N-NE winds and rough seas will continue 
to spread downstream from the Gulf of Tehuantepec and Gulf of 
Papagayo. A new set of long-period NW swell is forecast to enter 
the NW part of the area this weekend. Otherwise, high pressure 
will dominate the eastern Pacific, supporting moderate to locally
fresh trades and moderate seas through the rest of the week.
