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
1500 UTC.

...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: A reinforcing cold front is
moving across the Gulf of America. In its wake, a tight pressure
gradient in southeastern Mexico is bringing gale-force gap winds
in the Gulf of Tehuantepec region. Recent observations  reported
35 to 40 kt winds in the area. Rough to very rough seas are
expected with these winds. The gale winds are expected to
prevail through Tue night, then strong to near gale force winds
will gradually diminish through early on Thu. Rough seas in
north to northeast swell are expected to spread south-
southwestward to near 09N110W by Tue night.

Please read the latest HIGH SEAS FORECAST issued by the National
Hurricane Center at website -

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

The monsoon trough from 10N85W to 09N127W. ITCZ continues from
that point to beyond 10N140W. Scattered moderate convection is
from 06N-15N between 100W-129W.

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

Please see the Special Features section for details on an ongoing
Gulf of Tehuantepec gale-force gap wind event.

Long-period NW swell is moving through the offshore waters of
Baja California north of Cabo San Lazaro. Latest altimeter
satellite data pass indicates rough seas over these waters, with
the highest of the seas north of Punta Eugenia. Moderate seas in
NW swell are over the offshore waters from Cabo San Lucas to
Cabo San Lazaro. Elsewhere, a weak pressure gradient across the
region is allowing for moderate or lighter northwest to north
winds and moderate seas, except for slight seas in the Gulf of
California as noted in latest altimeter satellite data passes.

For the forecast, the long-period NW swell will gradually
subside through Tue. A second set of large NW swell is forecast to
enter the waters N of Punta Eugenia late Thu, and spread through the
remainder offshore waters of Baja California through Fri night.

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

Moderate to fresh NE to E winds continue to pulse in the Gulf of
Papagayo along with moderate seas. Gentle to moderate SW to W
winds and moderate seas are elsewhere.

For the forecast, moderate to fresh gap winds and moderate seas
are expected to pulse across the Papagayo region through Thu. The
Tehuantepec gap wind event will result in moderate N to NE winds
and moderate to rough seas in the far western offshore waters of
Guatemala and El Salvador through Tue night.

...REMAINDER OF THE AREA...

High pressure is the main feature over the eastern Pacific
subtropical waters. Long-period NW swell continues to spread
across the waters north of about 18N and and west of 115W. The
swell is leading to rough seas. The gradient in place is allowing
for moderate or lighter winds and moderate seas elsewhere north
and south of the ITCZ/monsoon trough west of 110W as noted in
the most recent altimeter satellite data passes over these
waters.

For the forecast, high pressure will continue to be the main
feature over the waters west of about 115W through midweek.
The NW swell will gradually subside through Tue. A cold front is
expected to approach 30N140W on Tue night, preceded by fresh to
strong southwest winds and rough to very rough seas that will
spread across the area through the end of the week.
