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
2100 UTC.

...TROPICAL WAVES...

A tropical wave has its axis along 106W, from 05N to 16N, moving
west at around 10 kt. No significant convection is noted at this
time.

A tropical wave has its axis along 129W from 04N to 17N, moving 
west at 10 kt. Scattered showers are noted across the northern
portion of the wave mainly N of 16N.

A tropical wave is along 137W, from 06N to 22N, moving west at 
around 10 kt. Associated convection is described below.

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

The monsoon trough extends off the coast of Costa Rica near
09N85W to 16N114W to beyond 11N140W. Scattered moderate 
convection is noted from 06N to 14N and E of 119W, and from 11N 
to 18N and W of 125W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh southerly winds are noted in the northern Gulf
of California, while gentle to moderate winds prevail elsewhere. 
Seas to 3 ft prevail across the northern Gulf, and 2-4 ft are
noted in the waters across the southern Gulf. Light to gentle 
winds prevail across the area with seas 5-6 ft.

For the forecast, gentle to moderate winds are expected to pulse
to fresh off Baja California at night through mid-week. Light to
gentle variable winds will continue to prevail elsewhere through
midweek. 

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

Light to gentle variable winds are north of the monsoon trough, 
with seas to 5 ft in SW swell. South of the monsoon trough, 
gentle to moderate southerly winds prevails, with seas 5-7 ft in
S to SW swell. Locally fresh southerly winds are likely 
occurring in the Ecuador and Colombia offshore waters S of 06N. 
Otherwise, strong thunderstorms are noted across the Central 
American offshore waters in addition to the Colombia coast. 

For the forecast, light to gentle variable winds will prevail N
of the monsoon trough through the middle of next week. Winds S of
the monsoon trough gentle to moderate winds are expected through
the forecast period.

REMAINDER OF THE AREA...

High pressure centered well north of the area continues to 
dominate the weather pattern. Across the waters north of the 
monsoon trough and roughly west of 120W, moderate NE to E winds 
prevail with seas of 5-7 ft. Gentle to moderate S to SW winds and
seas to 7 ft are south of the monsoon trough in SW swell, except
between the Galapagos Islands and 106W where fresh southerly 
winds are present.

For the forecast, surface ridging will continue to dominate the 
forecast region north of the monsoon trough through the weekend
and into early next week. A new set of SW swell may reach 03.4S 
and west of 100W beginning on Mon night, with seas reaching 8 ft.
Elsewhere, a pair of surface troughs will develop in the 
vicinity of the monsoon trough by mid-week enhancing winds/seas 
from 10N-20N between 110W and 120W.
