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
2150 UTC.

...SPECIAL FEATURES...

Gale Warning and Large NW swell: Large NW swell with a period of
10 to 15 seconds is moving across the E Pacific open waters N of
18N, with peak seas to 15 ft. Seas greater than 12 ft cover the 
waters N of 18N and W of 116W. These 12 ft seas will continue to 
propagate SE while gradually subsiding. By Sat morning, seas 
associated with this swell will subside below 12 ft. However, 
early on Sat, a cold front will enter the NW waters bringing a 
new set of NW swell with 12-14 ft seas over the far NW waters. 
Aside from the seas, strong to near gale-force winds will 
accompany this front, thus affecting the waters N of 20N ahead 
and behind the front. A tighter pressure gradient will develop as
the front extends from 30N130W to 20N140W Sat night, which will
lead to brief gales ahead and behind the front N of 27N through
Sun morning. Seas will peak near 19 ft with the strongest winds 
on Sat night. The 12 ft seas will spread S and E, covering much 
of the waters N of 14N and W of 120W by Sun night and reaching to
03N Tue evening before starting to subside. 

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

The equatorial trough extends from the coast of Colombia near 
07N78W to 06N83W to 05N91W. The ITCZ continues from 04N94W to 
05N120W to beyond 05N140W. Scattered moderate convection is off
the coast of Colombia and Ecuador from 01S to 09N E of 86W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 
 
A surface trough extends across the southern Gulf of California 
into Baja California Sur, then SW to near 20N122W. Large NW 
swell, with seas of 8-14 ft follows the trough, affecting the 
Baja Peninsula offshore waters N of Cabo San Lucas this afternoon.
The trough also supports moderate to fresh winds along the Gulf 
of California where seas are in the 3-4 ft range. Moderate to 
fresh NW winds prevail W of the Baja California peninsula, 
including the entrance of the Gulf of California and Jalisco
offshore waters. Elsewhere, light to gentle winds, and seas of 
5-6 ft, prevail in mixed S and NW swell. 

For the forecast, the surface trough will dissipate tonight near
Cabo San Lucas, Mexico. Large NW swell will subside below 12 ft
Sat morning, but will continue to spread rough seas to 10 ft 
across the waters off the Baja California peninsula and then 
across the waters off SW Mexico through the weekend. A low
pressure will develop over the region of Oaxaca early Sat 
morning, which will lead to the development of fresh to strong SW
winds along the coast with seas to 7 ft continuing through Sun. 
The next gap wind event in the Gulf of Tehuantepec is expected 
to begin Mon morning with possible gale-force winds developing  
during the afternoon hours. 

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

Moderate to fresh NE to E winds are in the Gulf of Papagayo 
region, where seas are in the 5-6 ft range. Winds in the Gulf of
Panama have diminished to gentle to moderate speeds and peak 
seas are 6 ft. Over the offshore waters between the coast of 
Ecuador and the Galapagos Islands, winds are gentle to moderate 
from the south with 5-6 ft seas in SW swell. Elsewhere, light to 
gentle winds, and seas of 4-6 ft prevail.

For the forecast, moderate to fresh NE winds in the Papagayo 
region will diminish to light to gentle speeds tonight. Gentle to
moderate winds in the Gulf of Panama will diminish to light to gentle
speeds on Sat. Looking ahead, a strong gale-force gap wind event
is forecast to begin in the Tehuantepec region Mon afternoon,
which will send off rough seas to 12 ft in northerly swell to 
the offshore waters of Guatemala and El Salvador Tue through 
early Wed. 

...REMAINDER OF THE AREA...

See the Special Features Section for information on an ongoing
large swell event and a gale warning. 

A surface trough extends from Baja California Sur SW to near 
20N122W. Large NW swell continues to propagate SE in the wake of
the trough with seas greater than 12 ft affecting the open waters
N of 17N and W of the Baja California Peninsula. However rough
seas to 8 ft extend further south to near 05N. High pressure of 
1022 mb is centered W of the Baja Peninsula near 25N128W and is
providing mainly gentle winds N of 20N and E of 132W. Over the
far NW waters, fresh to strong SW winds and 13-14 ft seas are
ongoing ahead of the next cold front that will be entering that
region. The pressure gradient between the area of high pressure
and lower pressure in the vicinity of the ITCZ is supporting 
moderate to fresh winds N of the ITCZ to near 20N and W of 120W. 
Gentle to moderate winds are found elsewhere E of 120W and S of
the ITCZ along with seas in the 5-7 ft. 

For the forecast, seas greater than 8 ft will spread SE through
the first half of the weekend, covering much of the waters N of
05N and W of 110W by Sat night before subsiding. Low pressure
will approach the NW waters Fri, with associated cold front
approaching the NW waters Fri evening. Fresh to strong winds are
expected ahead and behind the front. The front will usher in
another set of large NW swell, as discussed in the SPECIAL
FEATURES section above. The area low pressure will strengthen
while moving eastward near 31N. This could bring gale force 
winds into the forecast waters by late Sat afternoon or Sat 
evening.
