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
2000 UTC.

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

The monsoon trough extends from 10N85W to 08N93W to 09N115W. The
ITCZ continues from 09N115W to beyond 06N140W. Numerous moderate
to isolated strong convection is active from 03N to 10N east of 
88W. Scattered moderate and isolated strong convection is noted 
from 04N to 10N between 88E and 102W, and from 02N to 10N between
120W and 140W.

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

A weak cold front extends across weak cold front extends across 
the northern Gulf of California with moderate winds just ahead of
the front. Moderate winds prevail elsewhere in the Gulf of 
California, where seas are in the 2-4 ft range. Moderate to fresh
winds, and seas of 6-7 ft, are found off Baja California Norte. 
Gentle to moderate winds are off Cabo San Lucas, Cabo Corrientes,
and south of Southern Mexico. Gentle winds are elsewhere over 
the open waters off Mexico. Elsewhere over the open waters, seas 
are in the 4-5 ft range. 

For the forecast, the front will dissipate tonight into Wed. 
Strong winds may briefly pulse tonight following the front. High 
pressure building in the wake of the front will freshen winds 
west of the Baja California peninsula and off Cabo Corrientes 
through mid week, with large NW swell west of the Baja peninsula 
into Fri. Moderate or weaker winds and moderate seas, primarily 
in SW swell, will prevail elsewhere.

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

Moderate to fresh winds, and seas of 5-6 ft are over and 
downstream the Gulf of Papagayo. Gentle to moderate winds, and 
seas of 5-6 ft are between Ecuador and the Galapagos Islands. 
Gentle winds, and seas of 4-5 ft, prevail elsewhere. 

For the forecast, moderate to fresh NE to E winds are expected 
in the Papagayo region through Fri before diminishing this 
weekend. Winds in Papagayo will pulse to fresh to strong tonight.
Gentle to moderate winds will persist elsewhere. Expect moderate
to rough seas in long period SW swell between Ecuador and the 
Galapagos Islands Wed and Thu. Slight to moderate seas, primarily
in SW swell, will prevail elsewhere. 

...REMAINDER OF THE AREA....

A ridge prevails the waters north of 20N and west of 110W. The 
pressure gradient between the ridge and lower pressure in the 
vicinity of the ITCZ is supporting moderate trade winds N of the
ITCZ and west of 120W. NW swell has increase seas to 8 ft over
the waters N of 28N and W of 125W. Elsewhere seas N of the ITCZ 
are in the 6 to 7 ft range. Gentle to locally moderate winds and 
seas of 5 to 7 ft are noted elsewhere in a mix of swell. 

For the forecast, the pressure gradient between high pressure 
over the waters N of 20N and low pressure in the vicinity of the
ITCZ will support moderate to fresh NE winds north of the ITCZ 
and west of 120W through mid week. Seas in the 8 to 9 ft range in
NW swell will move across the waters north of 25N and west of 
120W through mid week, and combine with seas from trade winds 
from 10N to 20N west of 130W through the latter part of the week.
