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
0330 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 89W north of 08N, moving
west around 10 kt. Scattered moderate to isolated strong
convection is noted north of 12N and east of 90W.

The axis of a tropical wave is near 108W north of 08N, moving
westward around 15 to 20 kt. Scattered moderate convection is
noted from 12N to 18N between 103W and 108W.

The axis of a tropical wave is near 118W from 07N to 15N, moving
westward around 10 kt. Scattered moderate convection is noted
from 10N to 16N between 117W and 120W.

The axis of a tropical wave is near 128.5W from 05N to 14N,
moving westward around 5 kt. Scattered moderate convection is
noted from 07N to 15N between 121W and 132W.

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

The monsoon trough extends from coastal Panama near 09N84W to
09N130W. The ITCZ continues from 09N130W to beyond 09N140W.
Numerous moderate to strong convection is occurring north of 05N
and east of 85W. Scattered moderate to isolated strong convection
is noted from 03N to 13N between 92W and 101W.

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

A surface trough has been analyzed over the northern Gulf of
California into Baja California Sur, and fresh to locally strong
S to SE winds and seas of 2 to 5 ft are noted through the Gulf.
Elsewhere, ridging extends through the waters offshore of Baja
California, where moderate to fresh NW winds and seas of 4 to 6
ft in NW swell prevail. Otherwise, gentle to locally moderate
winds and seas of 3 to 6 ft in S swell are noted offshore of
southern Mexico.

For the forecast, fresh to strong S to SE winds will occur
across the central and northern Gulf of California into early Sat
as troughing prevails over the region. Moderate to locally fresh
winds will then pulse in this area into early next week.
Elsewhere, moderate to locally fresh NW are expected over the
Baja California waters into early Sat as high pressure prevails
to the northwest. Winds will diminish through Sat as the high
weakens. Looking ahead, moderate to fresh N gap winds will
develop in the Gulf of Tehuantepec early next week.

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

Moderate to fresh E to NE winds are occurring in the Gulf of
Papagayo as low pressure prevails over northern Colombia. Gentle
to locally moderate winds are noted elsewhere north of the
monsoon trough. To the south, moderate to locally fresh S to SW
winds are occurring. A long period S to SW swell is moving
through the regional waters, promoting seas of 4 to 7 ft, with
locally rough seas to 8 ft occurring south of the Galapagos
Islands.

For the forecast, moderate to fresh E to NE winds will pulse in
the Gulf of Papagayo through Sat morning as low pressure
dominates the south-central Caribbean. Winds will diminish for
the rest of the weekend before winds restrengthen by early next
week. Elsewhere, moderate to occasionally fresh S to SW winds
will occur south of the monsoon trough into next week. A long
period S to SW swell will promote rough seas over the equatorial
waters through Fri, with seas subsiding this weekend.

...REMAINDER OF THE AREA...

A 1034 high, centered north of the area near 39N141W, extends
ridging through the eastern Pacific waters north of the monsoon
trough and ITCZ. Moderate to locally fresh N to NE winds are
occurring in this region, with accompanying seas of 4 to 7 ft.
Elsewhere, a long period mixed SW and SE swell is moving through
the equatorial waters, promoting rough seas of 8 to 10 ft south
of 05N. Moderate to fresh SE winds are noted in this area.

For the forecast, moderate to fresh N to NE winds and moderate
seas are expected north of the monsoon trough and ITCZ into early
next week as ridging prevails over the eastern Pacific.
Elsewhere, rough seas over the equatorial waters will persist
through Fri morning before subsiding into Sat. Another modest
swell may produce rough seas south of the equator Sun into early
next week. Moderate to fresh SE winds will occur south of the
monsoon trough and ITCZ through the middle of next week.
