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
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
0800 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient between 
high pressure building across the Gulf of America in the wake of
a cold front and the eastern north Pacific monsoon trough is 
supporting strong to gale force gap winds and rough seas in the 
Gulf of Tehuantepec. Winds will diminish below gale force early
tonight. 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 09N84W to 06N96W to 10N120W to 
08N125W. The ITCZ extends from 08N125W to beyond 06N140W. 
Scattered moderate and isolated strong convection is noted from
03N to 08N E of 80W, and from 10N to 16N between 110W and 118W.

...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.

Aside from conditions in the Gulf of Tehuantepec discussed 
above, gentle to moderate NW winds prevail over the Gulf of 
California, and extends southward from the entrance of the Gulf 
to near Cabo Corrientes. Light to gentle winds are noted 
elsewhere. Seas are in the 4-6 ft range over the open waters off 
Mexico, and 2-3 in the Gulf of California.

For the forecast, the pressure gradient between high pressure 
north of the area and the eastern north Pacific monsoon trough 
will support gale force gap winds in the Gulf of Tehuantepec 
through early tonight, resulting in rough seas. Fresh to strong 
winds will then persist in the Gulf of Tehuantepec into Sat night
before diminishing. 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...

Fresh to strong NE winds are over and downstream the Papagayo 
region. Light to gentle winds are elsewhere north of the monsoon
trough. Gentle moderate winds are found south of the monsoon 
trough. Seas are in the 3-6 ft range in mixed SW and NW swells, 
reaching 7 ft in the Gulf of Papagayo.

For the forecast, fresh to strong NE winds and rough seas will 
prevail in the Papagayo region through Sun. 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 today 
due to a Gulf of Tehuantepec gale force gap wind event. 

...REMAINDER OF THE AREA...

The pressure gradient between ridging north of 20N and lower 
pressure in the vicinity of the ITCZ and lower pressure within
the monsoon trough is supporting moderate to locally fresh winds
north of the ITCZ/monsoon trough to 20N and west of 110W. The 
trade winds are contributing to 7-8 ft combined seas over these 
waters, assisted by a component of longer- period NW swell. 
Moderate or weaker breezes and moderate seas in a mix of swell 
are noted elsewhere. 

For the forecast, fresh trade winds and 7-8 ft seas in the trade
wind belt will decrease today as the high pressure north of the 
area weakens. A new set of NW swell with rough seas will arrive 
today and 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.
