...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: A strong cold front will move 
across the W Gulf of Mexico into S Mexico Fri producing a 
vigorous Tehuantepecer. This new gap wind event will begin by Fri
afternoon, with winds increasing to gale force Fri evening, and 
peaking as a strong gale on Sat. Winds are expected to diminish 
below gale force Sun afternoon, but remain strong through Sun 
night. Seas are likely to peak near 18 ft with a large area of 12
ft reaching to 10N100W. Winds are expected to diminish below 
gale force Sun afternoon, but remain strong through Sun night. 
Please read the latest NWS Offshore Zones Forecast issued by the 
National Hurricane Center at website 
https://www.nhc.noaa.gov/text/MIAOFFPZ7.shtml for more details.

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

The monsoon trough extends from 06N86W to low pressure near 
05N125W, where it transitions to ITCZ and continues to beyond
07N140W. No significant convection is presently noted.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Please see the Special Features section above for more information
on an upcoming Gulf of Tehuantepec gap wind gale event.

Away from strong N gap winds currently over the Gulf of 
Tehuantepec, winds are moderate or weaker across the Mexican 
Offshore Waters this morning as weak high pressure is in place 
west of Baja California. Seas are 6-8 ft over the Gulf of
Tehuantepec in mixed N wind waves and NW swell, 5-7 ft in NW
swell over the Offshore zones west of Baja and south of SW 
Mexico, and 2-4 ft over the Gulf of California.

For the forecast, see the Special Features section for the Gulf
of Tehuantepec. Building high pressure over the Great Basin 
should produce fresh to strong NW winds along the entire Gulf of 
California tonight through late Fri night. On Tue and Tue night,
a strong high pressure west of California is expected to produce
increasing NW winds and building seas over the waters west of 
Baja California Norte and the N Gulf of California.

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

Fresh to strong NE gap winds are occurring across the Papagayo 
region with seas are 5-6 ft. Light to moderate winds are 
occurring elsewhere with seas 3-5 ft. 

For the forecast, Fresh to strong NE winds will pulse in the 
Papagayo region through tonight, then again Sat night through Mon
night. Moderate to fresh N winds will continue in the Gulf of 
Panama until Mon night. Over the remainder of the area, winds 
should remain tranquil for the next several days. Large NW swell 
from an upcoming Gulf of Tehuantepec gap wind event will spread 
to the Guatemala and El Salvador offshore waters Sat morning 
through Sun morning. 

REMAINDER OF THE AREA

The pressure gradient between a weak 1024 mb high near 32N125W 
and the monsoon trough/ITCZ is producing only moderate or 
weaker winds across the remainder of the area. Isolated moderate
convection is noted between 10N-15N between 112W-117W. Seas are 
5-7 ft in NW swell.

For the forecast, gentle to moderate winds will continue across 
the basin through Fri. A surface trough is likely to amplify over
the open high seas near 127W during the weekend. It will be 
accompanied by fresh to strong NE to E winds along with building
seas within an area roughly bounded from 10N-22N and between 
125W-135W. These conditions are expected Sat through Sun night. 
It is possible that a low could briefly form along the trough. If
this transpires, then near-gale to gale force winds could occur 
within that area on Sun. Seas are anticipated to peak near 12 ft.

Looking ahead, on Mon and Tue a strong high pressure west of 
California is expected to produce increasing N to NE winds and
building seas north of 27N. The seas will be a product of both 
the N to NE wind waves and large long-period NW swell.
