...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: A strong high pressure system
centered over the eastern United States continues to support 
strong to gale-force N winds and rough seas to 12 ft in the Gulf
of Tehuantepec. Winds will diminish below gale force tonight into
early Sat. Winds and seas will further diminish Sat as the high 
pressure north of the area shifts eastward and the pressure 
gradient loosens. Please refer to the latest NHC High Seas 
Forecast at website 
https://www.hurricanes.gov/text/MIAHSFEP2.shtml for more details.

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

The monsoon trough extends from 08N82W to 09N110W to 10N125W. 
The ITCZ stretches from 10N125W to beyond 08N140W. Scattered 
moderate to isolated strong convection is observed from 03N to 
10N east of 90W, and from 06N to 16N between 103W and 113W.

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

Please refer to the Special Features section for details on an
ongoing Gale Warning in the Gulf of Tehuantepec.

Outside of the Gulf of Tehuantepec, the Mexican offshore waters
are dominated by a subtropical ridge located west of southern
California. Moderate northerly winds and moderate seas are
occurring from the southern Gulf of California to off Cabo
Corrientes and south of Cabo San Lazaro to the Revillagigedo
Islands. Elsewhere, light to gentle winds and slight to moderate
seas prevail.

For the forecast, high pressure north of the Gulf of Tehuantepec
will continue to support gale force gap winds and rough seas 
tonight into early Sat. Strong winds will then persist in the 
Gulf of Tehuantepec, diminishing to fresh speeds by Sat evening. 
A surface trough may impact the waters near the Revillagigedo 
Islands this weekend, with fresh to locally strong winds and 
rough seas possible this weekend into Mon. No significant swell 
events are forecast through the upcoming weekend. 

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

A strong ridge positioned well north of the area supports fresh
to strong NE winds across the Gulf of Papagayo and downstream to
89W. Seas in these waters are 6-8 ft. Farther west, moderate N 
winds and rough seas are occurring in the far offshore waters of 
Guatemala due to the gale-force winds in the Gulf of Tehuantepec.
Meanwhile, gentle to moderate southerly winds and moderate seas 
are found south of 05N. Elsewhere, light to gentle winds and 
slight to moderate seas are prevalent.

For the forecast, fresh to strong NE winds and rough seas will 
prevail in the Papagayo region through Sun. Rough seas in the 
Guatemala offshore waters will dimish Sat as the Tehuantepec gap 
event weakens. Moderate or lighter winds are forecast elsewhere 
through the forecast period. 

...REMAINDER OF THE AREA...

A subtropical ridge dominates the waters N of 15W and W of Baja
California supporting moderate to fresh trade winds north of the
monsoon trough and ITCZ to 20N. Seas in these waters are 5-6 ft.
In the eastern waters, moderate to fresh NE to E winds and seas 
of 6-7 ft are noted north of 10N and east of 102W due to gap 
wind event ongoing in Tehuantepec. South of the monsoon trough 
and ITCZ, moderate to locally fresh southerly winds and moderate 
seas are prevalent. Elsewhere, moderate or weaker winds and 
moderate seas prevail.

For the forecast, moderate to locally fresh trade winds and
locally rough seas will persist in the western waters through
Sat. Meanwhile, a new set of NW swell with rough seas is
approaching the NW waters and will persist into weekend north of
25N with seas to 10 ft. Another large set of NW swell may arrive
to the NW waters by the end of the weekend and into early next 
week.
