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 1200 UTC surface analysis and satellite imagery through
1430 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: The pressure gradient between 
high pressure north of the area and the equatorial trough is 
supporting gale- force gap winds across the Gulf of Tehuantepec. 
These gale- force winds will continue through this morning. Very
rough seas will accompany these gale force winds. The area of 
high pressure will weaken and shift eastward today, loosening the
pressure gradient with resultant winds and seas diminishing this
afternoon into Sat morning. Gale force winds may return to the 
Tehuantepec region early next week.

Hurricane Center at website -

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

A surface trough extends from 09N78W to 05N90W. The ITCZ extends
from 05N90W to 00N100W to beyond 02N140W. Scattered moderate 
convection is active from 02N to 03N between 95W and 100W.

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

See the Special Features section for more information on an
ongoing gale force gap wind event in the Gulf of Tehuantepec.

Outside of the Gulf of Tehuantepec, a weak pressure gradient is
resulting in moderate or weaker winds across the discussion 
waters. Moderate seas prevail over the open waters off Mexico, 
with slight to moderate seas over the Gulf of California. 

For the forecast aside from Tehuantepec, rough seas will briefly
impact the waters north of Punta Eugenia Sat night into Sun. 
Otherwise, winds will generally be moderate or weaker, with 
moderate seas over the open waters off Mexico and slight to 
moderate seas in the Gulf of California.

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

Fresh to strong winds are over the Gulf of Papagayo. Moderate to
fresh winds are found in the Gulf of Panama. Elsewhere, light to
gentle winds, and moderate seas, prevail.

For the forecast, rough to very rough seas generated from the 
Gulf of Tehuantepec gale force gap winds event will impact the 
outer waters of Guatemala today. Fresh gap winds will pulse to 
strong across the Papagayo region through Sun. Moderate N winds 
will pulse to fresh in the Gulf of Panama through Sun. Mainly 
light to gentle winds will prevail elsewhere through the forecast
period. Cross- equatorial SW swell will bring rough seas to the 
waters between the Galapagos Islands and Ecuador tonight through 
Sat night. 

...REMAINDER OF THE AREA...

High pressure is centered north of the area. The pressure 
gradient between this area of high pressure and lower pressure in
the vicinity of the ITCZ is supporting moderate to fresh winds 
north of the ITCZ to near 15N and west of 120W. Moderate to rough
seas in NE to E swell cover much of these waters. Elsewhere, 
moderate or weaker winds and moderate seas prevail.

For the forecast, winds will gradually diminish across the 
discussion waters through early next week. The rough seas will 
gradually subside through Sat. Cross- equatorial SW swell will 
bring rough seas east of 120W today. The rough seas will spread 
northward to cover the waters S of 10N and E of 120W Sat night 
before subsiding through Sun.
