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 0000 UTC surface analysis and satellite imagery through
0200 UTC.


The axis of a tropical wave is near 95W from 16N southward,
moving west at 10-15 kt. Scattered showers are along the northern
half of the wave.

The axis of a tropical wave is near 108W from 20N southward,
moving west at 10-15 kt. Scattered moderate convection is from
08N to 13N between 108W and 112W.


The monsoon trough extends from 08N79W to 15N109W to 12N120W.
The ITCZ extends from 12N120W to 09N140W. Scattered moderate
convection is from 06N-12N between 90W-105W, and from 07N-15N and
W of 124W.


Moderate to fresh winds, and seas of 5-6 ft, are over the Gulf of
Tehuantepec. Gentle to moderate winds, and seas of 1-3 ft, are
over the Gulf of California. Elsewhere a weak pressure gradient
is resulting in light to gentle winds, and seas of 4-5 ft.

For the forecast, fresh to strong northerly winds will prevail
in the Gulf of Tehuantepec through early next week before
diminishing. Moderate SE winds along the Gulf of California will
strengthen over the northern Gulf Sat before diminishing later in
the weekend. Moderate to fresh SE winds will move across the SW
Mexican offshore waters tonight through Sun. Elsewhere, light to
gentle winds are forecast through Tue.


Fresh to strong NE winds are over and downwind of the Gulf of
Papagayo with seas of 5 to 7 ft. Light to gentle winds are
elsewhere N of the monsoon trough. Gentle to moderate winds are
between the Galapagos Islands and Ecuador, with light to gentle
winds elsewhere S of the monsoon trough. Aside from seas over
the Gulf of Papagayo, seas are in the 4-6 ft range.

For the forecast, fresh to strong NE to E winds will continue in
the Papagayo region through the weekend then diminish slightly
early next week through the remainder forecast period. Mainly
gentle to moderate southerly winds and moderate seas will
continue between the coast of Ecuador and the Galapagos Islands
through Tue. Fairly tranquil conditions are forecast elsewhere.


Surface ridging prevails across the waters N of 20N. The pressure
gradient between the ridge and lower pressure in the vicinity of
the ITCZ and within the monsoon trough is supporting gentle to
moderate winds N of the ITCZ/monsoon trough and W of 120W. Light
to gentle winds are elsewhere N of the monsoon trough. Gentle to
moderate winds are S of the monsoon trough. Seas are in the 7-8
ft range in N swell N of 28N between 125W and 135W. Seas of 4-7
ft prevail over the remainder of the discussion waters.

For the forecast, gentle to moderate trade winds are expected
from 10N to 22N between 120W and 140W. Large northerly swell
will continue to prevail over the far northern waters through Sat
before subsiding Sun. Southerly swell to 8 ft may reach north of
equator to 10N and between 110W and 125W this weekend into early
next week. Winds may freshen south of the ITCZ and west of 110W
early next week.
