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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

The monsoon trough extends from 09N85W to 07N100W. The ITCZ runs
from 07N100W to 12N119W, then resumes from 07N133W to beyond 
07N140W. A surface trough breaks the ITCZ, analyzed from 19N118W
to 08N130W. Scattered moderate convection is in the vicinity of 
the trough between 109W-123W, from 07N to 10N E of 104W, and 
from 06N to 11N W of 130W. 

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

A surface trough prevails SW of the Revillagigedo Islands is 
aiding in scattered moderate convection in the vicinity of 
Socorro Island. Moderate E winds are also present in this area. 
Fresh to strong gap winds are noted in the Gulf of Tehuantepec. 
Elsewhere, gentle winds dominate N of 18N, with light and 
variable winds to the south. Seas are moderate, except slight S 
of 18N and in the Gulf of California. 

For the forecast, fresh to strong N winds in the Gulf of 
Tehuantepec will subside to gentle this morning. The surface 
trough just southwest of the Revillagigedo Islands will keep 
thunderstorms near the islands through Thu. Moderate to fresh N 
winds will pulse nightly in the northern Gulf of California 
through Thu night.

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

Surface ridging extending across the northern Caribbean supports
moderate to fresh NE winds and moderate seas in the Gulf of 
Papagayo. S of the monsoon trough, gentle to moderate S to SW 
winds and moderate seas prevail. Elsewhere, mainly winds with 
moderate seas in slight swells prevail.

For the forecast, moderate to fresh gap winds will persist near 
the Papagayo region into Thu night. Moderate or lighter winds 
and slight to moderate seas are expected elsewhere through the 
weekend.

...REMAINDER OF THE AREA...

A mid-level trough is noted N of 20N between 120W and 130W, 
inducing scattered moderate convection from 22N to 27N between 
119W and 128W. A surface trough is from 20N119W to 11N123W. 
Scattered moderate convection is in the vicinity of the trough 
between 110W-124W.

Broad and weak ridging extending south from a 1028 mb high 
pressure centered off Oregon is supporting gentle winds across 
the basin, with moderate seas. A zone of moderate NE winds and 
rough seas, in primarily NW swell, is noted W of 118W and N of 
07N. 

For the forecast, the large NW swell causing rough seas W of 
118W and N of 07N will gradually decay through today. Thereafter,
moderate seas will prevail into the weekend. Moderate to fresh 
trades will dominate N of the ITCZ to 20N and W of 120W through 
the week, with moderate or weaker winds elsewhere.
