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

A surface trough extends from 08N78W to 07N85W to 06N90W. The 
ITCZ continues from 06N90W to 04N99W to 06N110W to 04N118W to
05N135W to beyond 03N140W. Scattered moderate and isolated 
strong convection is noted from 04N to 09N between 83W and 93W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

Gulf of Tehuantepec: Fresh to strong winds will diminish to 20 
kt or less through Tue. Looking ahead, a cold front crossing the 
Gulf of Mexico later in the week may result in another gale event
in the Gulf of Tehuantepec Fri into Sat.

Gulf of California: Fresh to strong SW to W gap winds will 
prevail north of 29.5N into Tue. 

Elsewhere, a weak pressure gradient prevails across the area.
Light to gentle winds prevail, with seas in the 6-7 ft range 
west of the Baja California peninsula, and 4-6 ft seas prevailing
over the open waters off SW Mexico. Winds will increase 
slightly, to gentle to moderate, by midweek as the ridge of high 
pressure strengthens and tightens the pressure gradient over the 
area. NW swell propagating into the forecast waters west of the 
Baja peninsula will build seas to 8 ft by midweek. 

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

Gulf of Papagayo: Fresh to strong NE to E winds will pulse over
the Gulf of Papagayo region through Wed. The strongest winds will
occur during the overnight and early morning hours. 

Gulf of Panama: Gentle to moderate winds will prevail across the
Gulf of Panama through Tue. Winds will increase to moderate to 
fresh speeds Tue night and Wed as high pressure builds north of 
the region. Seas will build to 5-7 ft by midweek as SW swell 
combines with increasing wind waves. 

Elsewhere, generally light to moderate winds will prevail over
the waters west of Ecuador through Fri night. Wave heights between
Ecuador and the Galapagos Islands will remain in the 5-7 ft range
in SW swell for much of the week. Further offshore, expect 6-7 
ft seas SW of the Galapagos Islands by tonight. 

REMAINDER OF THE AREA...

High pressure of 1024 mb centered near 31N151W extends a ridge 
eastward, across the northern forecast waters. Gentle to 
moderate trades prevail north of the ITCZ to 15N and west of 
120W. Gentle to moderate anticyclonic wind flow was noted north 
of 15N. Latest altimeter data indicate seas in the 5-7 ft range.
The high pressure center will start to shift eastward tonight, 
moving north of the forecast waters by Tue night. This will 
tighten the pressure gradient over the area, and increase winds 
to fresh to strong, north of the ITCZ by Tue morning.
