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.

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

The monsoon trough extends from northern Colombia near 07N75W to
08N92W to 10N110W to 06N124W. The ITCZ continues from 06N124W to
03N140W. Scattered moderate and isolated strong convection is 
noted from 01N to 06N between 77W and 81W, from 04N to 10N
between 84W and 99W, from 05N to 12N between 113W and 117W, and 
from 02N to 07N between 117W and 135W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge associated with 1028 mb high pressure centered 
near 34N131W is west of the Baja California peninsula. The 
gradient between the ridge and low pressures over Mexico is 
supporting moderate to locally fresh winds near the Baja 
California peninsula. Gentle to moderate winds prevail elsewhere 
over the waters off Mexico. Seas are in the 4-7 ft range in a 
mix of northwest and south swell over the open waters off Mexico.

For the forecast, moderate to fresh NW to N winds will prevail 
west of Baja California through Sat night, becoming fresh to 
occasionally strong on Sun. Fresh to strong winds will filter
through Baja California passages across the northern and central
Gulf of California Sun night. Large NW swell will build west of 
Baja California Sun and Mon.

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

Light to gentle winds prevail across the region, except moderate
offshore of Ecuador. Seas are in the 5-7 ft range in lingering 
southerly swell.

For the forecast, light to gentle winds will continue across the
region through Sun night, with southerly winds increasing south 
of the monsoon trough axis early next week. Moderate southerly 
swell will gradually decay through Tue.

REMAINDER OF THE AREA...

A broad ridge associated with 1028 mb high pressure centered 
near 34N131W dominates the forecast waters. The gradient between 
the high and lower pressure in the vicinity of the ITCZ is 
supporting moderate to locally fresh winds north of the ITCZ, 
and seas in the 5-8 ft range. Gentle to moderate winds and seas 
in the 5-7 ft range prevail elsewhere.

High pressure will continue north of the area through the  
weekend. Large northwest swell and fresh to strong northerly
winds will spread south of 30N between 120W and 130W Sun and 
Mon. Marine conditions will improve on Tue and Wed.
