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
0840 UTC.

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

The monsoon trough extends from 08N78W to 06N95W to 08N110W. The
ITCZ continues from 08N110W to 08N110W to beyond 03N140W. 
Scattered moderate convection is noted from 03N to 05N between 
95W and 100W, and from 05N to 08N between 105W and 120W.

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

Recent satellite derived data indicates mostly moderate NW winds
persist off Baja California this morning, although winds to 20 kt
may be funneling near the coast of Cabo San Lucas. Combined seas
are 5 to 8 ft, with highest wave heights near Guadalupe Island. 
Gentle to moderate southerly winds and slight seas are noted over
the Gulf of California and off southern Mexico. Areas of smoke 
from agricultural fires persist off southern Mexico.

For the forecast, moderate to locally fresh NW winds offshore 
Baja California Norte will gradually diminish through Fri as low 
pressure over the Colorado River Valley weakens and moves east. 
Fresh SW gap winds over the northern Gulf of California will 
pulse this afternoon while moderate W gaps winds will persist 
across portions of central and southern Gulf through Wed morning.
Large NW swell impact the outer waters of Baja California Norte 
will subside through tonight. Gentle to moderate breezes and 
slight to moderate combined seas will persist elsewhere through 
late week. Expect areas of smoke off southern Mexico today. 
Looking ahead, fresh to strong northerly gap winds are possible 
over the Gulf of Tehuantepec Sun. 

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

Light to gentle breezes and slight to moderate combined seas in 
SW swell dominate the region. For the forecast, a weak pressure
gradient will support light to gentle breezes across the region 
through late week. Expect slight to moderate combined seas 
primarily in S to SW swell. Also, areas of smoke from
agricultural fires may persist over the offshore waters. 
 
...REMAINDER OF THE AREA...

Ridging to the north of the area is weakening and shifting
farther north ahead of a cold front extending to the northeast of
the Hawaiian Islands. This pattern is supporting moderate trade 
winds north of 05N and west of 120W. Mainly gentle breezes are 
evident elsewhere. Combined seas are 7 to 8 ft in northerly swell 
north of 28N and est of 125W and 4 to 7 ft elsewhere.

For the forecast, the large NW swell will persist into tonight 
for waters north of 28N and east of 125W, then diminish to less 
than 8 ft Wed. Moderate trade winds will persist from 05N to 20N 
and west of 125W through the remainder of the week. The cold 
front will reach 30N140W on Wed, briefly producing S winds near 
20 kt and seas around 7 ft, before the front stalls along 
137W-138W and gradually dissipates through Fri.
