from the Equator to 30N, between 120W and 140W. The following

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: A cold front is moving across 
the Gulf of America and will depart the basin tonight. The 
pressure gradient between strong high pressure building in the 
wake of the front and the eastern north Pacific monsoon trough is
supporting strong to gale force gap winds and rough to very rough seas
in the Gulf of Tehuantepec. A plume of fresh to strong N to NE 
gap winds and seas of 8 to 10 ft will reach into Pacific waters 
up to 480 nm downstream of the Gulf of Tehuantepec by late today.
Winds and seas will 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 the coast of Costa Rica near
09N84W to 06N100W to 09N120W. The ITCZ stretches from 09N120W to
beyond 07N140W. Scattered moderate and isolated strong 
convection is observed from 04N to 08N and east of 85W and from 
07N to 16N and between 108W and 127W.

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

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

Aside from conditions in the Gulf of Tehuantepec discussed 
above, moderate to locally fresh NW winds and slight to moderate
seas prevail in the Gulf of California. Gentle to moderate NW-N winds
and moderate seas extend from the entrance of the Gulf to near 
Cabo Corrientes. Elsewhere in the Mexican offshore waters, gentle
to moderate winds and moderate seas are prevalent.

For the forecast, gale force gap winds in the Gulf of 
Tehuantepec will continue through Fri night, resulting in rough 
to very seas. Fresh to strong winds will then persist in the Gulf
of Tehuantepec into Sat night before diminishing. Farther north,
moderate to locally fresh winds, in the central and northern 
Gulf of California will diminish by this evening. A weak cold 
front or trough will move into the waters off northern Baja 
California, possibly supporting moderate to fresh winds near the 
entrance to the Gulf of California to Cabo San Lucas to the 
Revillagigedo Islands Sun and Sun night. 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...

Strong high pressure north of the Caribbean basin continues to
support fresh to strong NE winds across the Gulf of Papagayo
region, extending downstream to 90W. Seas in these waters are 6-8
ft. Farther south, moderate to locally fresh southerly winds and
moderate seas are occurring south of 04N. Elsewhere, gentle to
locally moderate winds and slight to moderate seas prevail.

For the forecast, high pressure north of the area will support fresh
to strong NE winds in the Papagayo region through Sun. N winds 
will pulse to fresh speeds at night in the Gulf of Panama through
Fri night. Moderate or lighter winds are forecast elsewhere 
through the remainder of the week and into the weekend. While no 
significant swells are forecast, seas will build slightly in the 
Papagayo region due to the fresh to strong winds, and offshore 
Guatemala to locally rough through Fri due to a Gulf of 
Tehuantepec gale force gap wind event. 

...REMAINDER OF THE AREA...

A 1023 mb high pressure system centered north of the remainder of
the tropical eastern Pacific and lower pressure in the deep
tropics support moderate to fresh easterly trade winds north of
the monsoon trough and ITCZ to 20N. Seas in these waters are 6-9
ft. South of the monsoon trough and ITCZ, moderate to locally
fresh southerly winds and seas of 6-8 ft are prevalent.
Elsewhere, moderate or weaker winds and moderate seas prevail.

For the forecast, fresh trade winds and 7-9 ft seas in the trade
wind belt will gradually decrease through the end of the week as
the high pressure north of the area weakens. A new set of NW 
swell with rough seas may arrive by the end of the week and into 
next weekend north of 25N. Moderate winds and seas will persist 
elsewhere. A large set of NW swell may arrive to the NW waters by
the end of the weekend and into early next week.
