based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1545 UTC.

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

Surface trough extends from 10N85W to 06N88W. The ITCZ extends 
from 06N88W to 02N110W to 05N140W. Scattered moderate convection
is noted from 04N to 07N between 89W and 102W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh NW winds prevail west of Baja California.
Gentle winds are occurring over the northern Gulf of California,
with fresh winds over the southern Gulf of California, extending
to Cabo Corrientes. Gentle winds are noted elsewhere. Seas are 5
to 7 ft to the west of Baja California and over the southern 
Gulf of California extending south to Cabo Corrientes, with 3 to 
6 ft seas elsewhere.

Moderate to fresh winds will gradually diminish to gentle to
moderate all areas today. A weakening cold front will cross Baja
California tonight into Tue. In the wake of this front, winds 
will strengthen to strong in the northern Gulf of California 
overnight into early Tue.

Looking ahead, gale force gap winds are likely to develop in the
Gulf of Tehuantepec by Fri night.

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

Moderate NE to E winds are noted within and downstream of the 
Papagayo region and Gulf of Panama. Light to gentle winds prevail
elsewhere. Sea heights are in the 5-7 ft range over and downwind
of both the Gulf of Papagayo and Gulf of Panama. Seas range
between 4 to 6 ft elsewhere. Fresh NE winds will continue to 
pulse across the Papagayo region into Tue night, with highest 
winds expected during the overnight hours. Seas associated with 
these winds will be 5 to 7 ft. Fresh north winds in the Gulf of 
Panama will pulse at night through Tue, with seas in the 5-7 ft 
range also. Light to gentle winds, with seas in the 3 to 6 ft 
range, will prevail elsewhere through mid week.

REMAINDER OF THE AREA...

Surface ridge prevails across the area. The pressure gradient 
in the area is supporting moderate to fresh winds north of the 
ITCZ to near 20N and west of 115W. Seas in this area are in the 
8-10 ft range. A cold front extends from 30N125W to 26N140W. 
Fresh to strong northeasterly winds prevail northwest of the 
front. The front will continue moving east across the waters 
north of 25N through Tue while weakening. The front has ushered 
in a new set of large NW swell into the area, with seas peaking 
near 13 ft over the far NW waters. This swell will move through 
the northern waters into Tue night while slowly subsiding 
subside. Another cold front will enter the NW waters on Wed. 
This front will usher in another set of NW swell into the NW 
waters, peaking near 13 ft once again on Thu.
