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
2030 UTC.

...SPECIAL FEATURES...

Showers and thunderstorms associated with a broad area of low 
pressure located a few hundred miles south of the southern coast of 
Mexico have become a little better organized since this morning.
The low is currently analyzed near 14N105W, with a minimum 
pressure of 1007 mb. Scattered moderate convection prevails from
10N-19N between 102W-109W. Seas of 6-8 ft are noted in the 
vicinity of the low. Environmental conditions appear conducive 
for some further development of this system during the next day 
or so, and a short-lived tropical depression could form during 
that time. On Friday, the system is forecast to move over cooler 
waters and development after that time is not expected. The 
disturbance is forecast to move northward to northwestward at 10 
to 15 kt, remaining offshore of the southwestern coast of 
Mexico. This system has a medium chance for tropical formation 
within the next 48 hours. Please refer to the latest NHC Tropical
Weather Outlook at www.hurricanes.gov for more details.

...TROPICAL WAVES...

A tropical wave over the eastern part of the area has its axis 
along 95W north of 08N. The wave is moving westward around 10 to
15 kt. Scattered moderate convection is noted from 10N-15N
between 93W-98W.

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

The monsoon trough extends from 10N86W to 07N130W. The ITCZ 
continues from 07N130W to beyond 08N140W. Scattered showers are 
noted along the ITCZ.

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

Please see the Special Features section for information on a 
broad area of low pressure that is well offshore southern Mexico
with potential for tropical cyclone formation. Otherwise, a 
weak pressure gradient over the area is allowing for light to
gentle winds over the offshore waters. Seas range from 3 to 6 
ft. In the Gulf of California, moderate to fresh southerly winds 
are present along with seas of 2 to 5 ft. 

Scattered showers and thunderstorms are over the offshore waters
between Acapulco and Manzanillo related to the Special Features
low pres center.

For the forecast, scattered showers and thunderstorms will 
continue over the offshore the coast of southern Mexico through 
the end of the week due to increasing moisture associated with 
the aforementioned broad area of low pressure described above 
under Special Features. Otherwise, the gradient between a surface
trough along the Baja California Peninsula and high pressure 
west of the area will continue to induce moderate to fresh 
southeast winds along the Gulf of California through early Thu. 
Fresh to strong north gap winds are expected in the Gulf of 
Tehuantepec region Thu night through Fri.

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

Moderate to fresh south to southwest winds are present over the 
offshore waters of Costa Rica, Panama, and Colombia, while 
mostly gentle to moderate southwest winds are over the remainder 
of the offshore waters. Seas across the waters N of 08N are in 
the 4 to 6 ft range due to long-period south swell, with slightly
higher seas of 5 to 7 ft S of 08N. 

For the forecast, moderate to fresh winds will continue through
the weekend across the offshore waters. Seas will increase to 8 
ft in the area of stronger and persistent winds. Scattered 
showers and thunderstorms are expected over most of the forecast 
waters through the next few days. Gusty winds and locally rough 
seas may accompany some of the activity. 

...REMAINDER OF THE AREA...

Surface ridging extends southeastward from strong high pressure 
of 1033 mb that is located well north of the area. The ridge 
covers the waters north of 15N and west of 130W. Moderate 
northeast to east winds are north of 15N west of 130W. Gentle to
moderate north to northeast winds are elsewhere north of the 
ITCZ. Seas are 5 to 7 ft over these waters. Light to gentle 
northwest to north winds are north of the monsoon trough. 
Moderate to fresh east to southeast winds continue south of the 
ITCZ and monsoon trough west of 100W along with seas of 7 to 9 
ft in south swell. 

For the forecast, expect for the moderate to fresh east to 
southeast winds south of the ITCZ and monsoon trough west of 100W
to continue through Fri, than expand eastward through the 
weekend. Seas of 6 to 8 ft with these winds are forecast to 
subside slightly to 5 to 7 ft in long-period south swell. 
Elsewhere, fresh northwest to north winds west of the Baja 
California Norte offshore waters will weaken by the end of the
week while moving west, then another pulse of fresh winds will 
develop this weekend with moderate seas. These conditions will
continue through early next week.
