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 0600 UTC surface analysis and satellite imagery through
0800 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 89W north of 05N, moving 
westward at 10 to 15 kt. Nearby convection is discussed in the 
ITCZ/monsoon trough section below.

The axis of a tropical wave is near 97W north of 05N, moving 
westward at around 10 kt. Nearby convection is discussed in the 
ITCZ/monsoon trough section below.

The axis of a tropical wave is near 116W from 05N to 22N, moving
westward at around 10 kt. Nearby convection is discussed in the 
ITCZ/monsoon trough section below. 
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 10N86W to 10N106W to 11N115W to 
07N120W. The ITCZ extends from 07N120W to 08N140W. Scattered 
moderate and isolated strong convection is noted from 02N to 16N
between 88W and 102W, and from 06N to 11N between 107W and 120W. 

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

Gentle to moderate winds prevail west of the Baja California
peninsula, extending southward to W of the Revillagigedo Islands.
Light to gentle winds are noted elsewhere over the open waters
off Mexico. Seas are in the 4-6 ft range. Over the Gulf of
California, gentle to moderate winds and seas of 2-4 ft prevail.

For the forecast, winds may strengthen in the northern Gulf of 
California late in the week. Otherwise, gentle to moderate winds 
will prevail across the forecast waters, pulsing to moderate to 
fresh in the Gulf of Tehuantepec through mid-week. Moderate seas 
will prevail across the open waters over the next several days. 
An area of low pressure could form several hundred miles offshore
of southwestern Mexico late this week. Environmental conditions 
are expected to only be marginally conducive for development of 
this system as it moves to the west- northwest, well off the 
coast of Mexico. 

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

Fresh to locally strong winds are over the Gulf of Papagayo, 
with moderate winds extending downstream of the Papagayo region.
Gentle winds prevail elsewhere N of the monsoon trough. Gentle 
to locally moderate winds are south of the monsoon trough. Seas 
are in the 4-6 ft range. 

For the forecast, fresh to strong E winds will pulse in the Gulf
of Papagayo through Wed night, diminishing to moderate to fresh 
thereafter. Otherwise, gentle to moderate winds will prevail. 
Moderate seas in S to SW swell will prevail over the regional 
waters during the period, building near rough south of the 
Galapagos Islands by the end of the week. 

...REMAINDER OF THE AREA...

High pressure prevails over the waters north of 20N. Gentle to 
moderate winds prevail across the discussion waters. Seas are in
the 4-7 ft range, reaching 8 ft N of the ITCZ and W of 137W.

For the forecast, little change in winds and seas are anticipated
over the next few days. Cross equatorial, rough southerly swell 
will move into the waters S of 06N and W of 100W by the middle 
of the week, persisting into the weekend. Seas may build to near 
8 ft in fresh N swell along 30N between 120W and 130W at the end 
of the week into the weekend. Winds may freshen in the NW waters
by the weekend.
