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
0230 UTC.

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

A surface trough extends from 08N78W to 06N86W to 08N129W. The 
ITCZ extends from 08N129W to 06N140W. Scattered moderate and 
isolated strong convection is noted from 01N to 08N east of 87W,  
and from 05N to 13N between 104W and 128W. Scattered moderate
convection is noted from 01N to 08N between 95W and 101W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

The pressure gradient between high pressure north of the area 
and lower pressure over the western U.S. is supporting moderate
to fresh NW winds off Baja California Norte, with moderate winds
off Baja California Sur. Moderate winds are noted near Cabo 
Corrientes, with light to gentle winds in the Gulf of 
California. Gentle to moderate winds are elsewhere offshore the 
open waters off Mexico. Seas are in the 8 to 10 ft range 
offshore of the Baja California peninsula. Seas of 5 to 6 ft are
elsewhere offshore Mexico, and 1 to 3 ft over the Gulf of 
California, except 2 to 4 ft in the central Gulf of California. 
Patchy to areas of haze are possible near the coast of 
southwestern Mexico due to nearby agricultural fires.

For the forecast, northerly swell west of the Baja California 
peninsula will gradually subside through the remainder of the 
week. Moderate winds will prevail off Cabo Corrientes into early 
Fri, then pulse to fresh to strong Sat night. A tight pressure 
gradient will develop offshore of Baja California Norte Sat. 
Winds over this area will strenghten, and seas will build to 8 
ft, through the remainder of the upcoming weekend and into early 
next week. 

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

Fresh winds are noted over the Papagayo region offshore
Nicaragua. Gentle to moderate winds are between Ecuador and the 
Galapagos Islands. Light to gentle winds prevail elsewhere. Seas 
are in the 4 to 6 ft range, reaching 7 ft over the Papagayo 
region offshore Nicaragua as well as the waters between Ecuador 
and the Galapagos Islands in decaying S to SW swell. 

For the forecast, high pressure north of the area will support 
pulses of fresh winds into the Papagayo region offshore Nicaragua
through early Sun. Moderate winds in the Gulf of Panama will 
develop tonight, gradually diminish to gentle by the end of the 
week, then will increase to moderate this weekend. Gentle to 
moderate S winds will prevail between Ecuador and the Galapagos 
Islands. Mainly light to gentle winds are expected elsewhere. 
Moderate S to SW swell offshore of Ecuador to the Galapagos 
Islands will subside through the end of the week. 

REMAINDER OF THE AREA

High pressure prevails north of the area. The pressure gradient 
between this area of high pressure and lower pressure in the 
vicinity of the ITCZ is supporting mainly moderate to fresh 
anticyclonic flow north of the ITCZ and west of 115W, locally
strong near 12N130W. Seas within this area are in the 7 to 10 ft
range. Winds are gentle to moderate elsewhere. Long period 
southerly swell is affecting the area mainly south of the 
equator, with seas to 7 ft between 90W and 100W.

For the forecast, conditions are expected to gradually improve, 
with the majority of 8 ft seas expected to subside by Thu, and 
fresh winds diminishing by Fri. Fairly tranquil marine conditions
will then prevail for the end of the week.
