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 0000 UTC surface analysis and satellite imagery through
0300 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: High pressure ridging will
build southward along eastern Mexico in the wake of a late-
season cold front that will move across the northern Gulf of 
America tonight through Mon. The pressure gradient between the 
ridge and relatively lower pressure south of Mexico should 
tighten enough to support a brief occurrence of gale-force 
northerly winds in the Gulf of Tehuantepec Sun night into Mon 
morning. The gradient will then relax enough as high pressure 
north of the area shifts eastward during Mon enabling the gale 
winds to diminish to strong speeds. Seas with this upcoming gale 
event are expected to peak to around 11 ft. Lingering rough seas 
later during Mon will subside late Mon. Marine interests 
transiting through, or near the Gulf of Tehuantepec should take 
the necessary action to avoid hazardous marine conditions over 
the affected waters.

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

A surface trough extends from northwest Colombia southwestward to 
07N78W to 09N90W to 05N107W, where it transitions to the ITCZ 
and continues to 05N120W to beyond 05N140W. A second ITCZ extends
from 02S94W to beyond 03S140W. Scattered moderate convection is
depicted from 07S to 07N between 84W and 105W. Similar 
convection is depicted from 02.5N to 08.5N between 118W and 140W. 

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

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

A high pressure NW of the area extends a ridge to about 15N and 
west of 113W. The pressure gradient between the ridge and lower 
pressures over Mexico is supporting moderate to locally fresh northwest
winds west of the Baja California Peninsula. Elsewhere over the 
Pacific, winds are moderate or weaker in speeds. Seas are 4 to 6
ft in northwest swell over the waters northwest of Cabo 
Corrientes and 4 to 5 ft in south swell over the waters 
southeast of Cabo Corrientes. Mostly moderate northwest winds are
in the Gulf of California. Seas are 3 to 4 ft in the southern 
sections of the Gulf and 2 to 3 ft elsewhere. 

For the forecast, aside from the upcoming Tehuantepec gale event, 
rather quiet conditions will remain over the forecast waters 
through the rest of the weekend. A set of northwest swell will 
move through the waters west of Baja California Norte late Tue 
before it subsides Wed and Wed night while it propagates through
the rest of the Baja California offshore waters. Seas are expected 
to peak to around 9 ft with this swell. Fresh to locally strong 
northwest winds are forecast over the Pacific waters of Baja 
California beginning Wed night and Thursday night. Otherwise, 
high pressure will dominate the general weather pattern well into
the upcoming week providing for moderate to fresh winds 
northerly winds northwest of Cabo Corrientes, and mostly light to
gentle winds southeast of Cabo Corrientes.

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

Light to gentle variable winds prevail across the region along 
with seas 4 to 6 ft. Scattered moderate convection is present 
from 04N to 07N between 84.5W and 87W. Scattered moderate 
convection is also depicted in the vicinity of the Galapagos 
Islands.

For the forecast, winds may pulse to fresh speeds in the Gulf of
Papagayo region late Mon night into Tue morning. Otherwise, 
rather tranquil conditions are expected to hold over the Central 
American and the equatorial waters for the next few days.

...REMAINDER OF THE AREA...

High pressure is NW of the area with a ridge extending to 15N and
west of 113W. A late-season cold front is just northwest of the 
discussion area. A weak pressure gradient between the ridge and 
relatively lower pressure to its south associated to the ITCZ is
sustaining an area of moderate to locally fresh northeast trades
over the western part of the domain from 14N to 20N west of 
about 122W. Seas within this area of trades are 5 to 7 ft in 
mixed swell. No additional deep convection is occurring away from
the surface trough/ITCZ.

For the forecast, little overall change is expected in the present 
synoptic pattern into early next week, with respect to winds and 
seas. The aforementioned cold front will move into the northwest 
part of the area late tonight, then move east-southeastward and 
weaken as moves across the north-central and northeast forecast 
waters from late Mon through Tue. The main impacts from this 
front will be from a set of large northwest to north swell that 
will trail the front as seas are expected to build to a maximum 
of 12 or 13 ft on Mon night over the far northwest waters. Seas 
of 8 ft and greater will reach to a line from near 30N121W to 
20N140W by late Tue.
