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 1800 UTC surface analysis and satellite imagery through
2000 UTC.

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

The monsoon trough extends from 09N84W to 10N94W to 10N112W to
06N122W to 10N140W. Scattered moderate and isolated strong 
convection is noted from 06N to 15N between 91W and 100W, and 
from 01N to 10N between 110W and 140W.

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

A weak pressure gradient prevails across the area. With the weak
pressure gradient, light to gentle winds prevail over the
discussion waters, except gentle to locally moderate winds off 
Cabo San Lucas. Seas are in the 5-6 ft range over the open 
waters off Mexico, and 3 ft or less in the Gulf of California. 

For the forecast, light to gentle winds will prevail across the 
waters of Baja California through Sat night, increasing slightly 
thereafter. Gentle to occasionally moderate SW to S winds are 
expected inside the Gulf of California and near the tip of Baja 
California Sur. Light to gentle winds will dominate the waters 
between Cabo Corrientes and Tehunatepec.

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

Gentle to moderate winds prevail in the Gulf of Papagayo as well
as between the Galapagos Islands and Colombia. Light to gentle 
winds are found elsewhere. Seas are in the 6-7 ft range between 
the Galapagos Islands and Colombia, and 4-6 ft elsewhere.

For the forecast, gentle to moderate winds and moderate seas 
will prevail across the offshore waters into the weekend. Winds 
may pulse to moderate to locally fresh in diurnal offshore flow 
in the immediate Gulf of Papagayo and near the Gulf of Guayaquil 
during the upcoming weekend into early next week.

...REMAINDER OF THE AREA...

Broad troughing prevails across the waters N of 20N. The 
pressure gradient between this trough, and high pressure NW of
the area is supporting moderate to locally fresh winds over the
NW waters. Gentle to moderate winds are elsewhere N of the
monsoon trough and 30W. Light to gentle winds prevail elsewhere 
N of the monsoon trough. Moderate to fresh winds are S of the 
monsoon trough and W of 135W, with gentle to moderate winds 
elsewhere. Northerly swell is bringing rough seas over the waters
N of 28N between 129W and 135W. Mainly moderate seas are found 
elsewhere, except locally rough south of the equator. 

For the forecast, moderate or weaker are expected across the 
much of the open waters, except at least moderate to fresh near 
transient embedded low pressure areas along western portion of 
the monsoon trough through early next week. Northerly swells 
mixed with the longer period southerly swells with seas of 7-9 ft
will linger across the N-central waters through tonight before 
decaying. Otherwise, moderate seas will dominate the open waters,
locally rough in the S-central waters through Sat, as well as 
near any of the embedded lows within the monsoon trough.
