Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 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
0900 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 93W/94W, moving W around 15 
kt. Mainly scattered showers were noted near the tropical wave 
axis.

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

The monsoon trough extends from the coast of Panama near 08.5N78W
to 13N92W to 06N110W. The ITCZ continues from 06N110W to 08N130W
to 07N140W. Scattered moderate and isolated strong convection 
was noted within an area bounded by 11N86W to 10N86W to 10N90W 
to 13N90W to 13N88W to 11N86W, including the Gulf of Papagayo, 
within an area bounded by 08N96W to 06N109W to 05N114W to 
06N118W to 09N109W to 10N101W to 08N96W, and also within an area
bounded by 08N133W to 06N135W to 06N140W to 10N140W to 10N133W 
to 08N133W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

Light to gentle winds prevail off the coast of Baja California 
Norte. Mainly gentle to moderate NW winds prevailed elsewhere 
across the open forecast waters, except off the coast of Cabo San
Lucas, where locally fresh winds prevail. Light winds prevail 
over the Gulf of California. Over the open waters off Mexico, 
seas are mainly in the 4-6 ft range, reaching 7-8 ft just west of
Guadalupe Island, in N swell. Seas over the Gulf of California 
are 3 ft or less.

High pressure west of Baja California will maintain gentle to 
locally moderate NW winds over the offshore waters through the
next several days. Winds may briefly pulse to locally fresh 
off Cabo San Lucas each late afternoon and evening for the next 
several days. Seas will subside across the waters west of 
Guadalupe Island today.

Northerly gap winds are expected to develop over the Gulf of 
Tehuantepec Mon night as the local pressure gradient tightens, 
continuing until Wed afternoon, then returning Thu night. Seas 
will build to up to 8 ft during these winds.

Gap winds in the northern Gulf of California will increase
to fresh to strong Thu night.

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

Gentle to moderate S to SW wind flow is noted across the 
forecast waters S of 08N, with light flow N of 08N. Little change
in these winds are expected through the next several days. Seas 
are in the 4-7 ft range, and will subside slightly through the 
early part of the week.

REMAINDER OF THE AREA... 

High pressure of 1035 mb centered well N of the area near 
43N131W extends a ridge SE to just S of the Revillagigedo 
Islands. Moderate to fresh N to NE winds prevail north of the 
ITCZ and west of 125W, with gentle to moderate winds east of
125W. Seas are in the 8-10 ft range in northerly swell N of 27N 
between 123W and 130W, and 5-7 ft elsewhere, except from 09N to 
13N to the west of 135W where seas are reaching near 8 ft in
mixed swell. The northerly swell will continue to bring seas of 
8 ft or greater across the waters west of Guadalupe Island
through early Mon, subsiding Mon afternoon.

Farther south, southerly swell will continue dominating the 
waters east of 120W through the early part of the week. Earlier
altimeter data revealed seas to 8 ft as far north as 07N between
96W and 103W. Seas have started to subside, and will subside to
less than 8 ft later today.
