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

The monsoon trough extends from 09N85W to 07.5N96W to 09N119W.
The ITCZ continues from 09N119W to 04N140W. Scattered moderate
convection is noted from 02N to 09N between 80W and 95W.
Scattered moderate isolated strong convection is noted from 02N
to 09N between 95W and 110W, and from 03N to 08N between 125W
and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong northwest winds over the central Gulf of California will
diminish early Wed. Gentle to moderate winds prevail elsewhere 
over the open waters off Mexico. Seas are in the 3-5 ft range in 
a mix of northwest and south swell over the open waters off 
Mexico. 

For the forecast, high pressure will build west of the region Wed 
supporting fresh winds off Baja California. Farther south, 
slight to moderate seas will begin to build Wed as a new set of 
southerly swell arrives.

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

Moderate to fresh gap winds prevail over the Gulf of Papagayo
and the Gulf of Panama. Gentle to moderate winds persist 
elsewhere. Seas are in the 4-6 ft range in lingering southerly 
swell.

For the forecast, gentle to moderate winds will persist across 
the region, with subsiding southerly swell. Fresh to strong gap 
winds are expected tonight across the Gulf of Papagayo. 
Additional southerly swell will begin to move propagate into the 
region tonight and through early Thu, at which time it will begin
to decay. Prior to doing so, the swell will induce maximum seas 
of 8 ft.

REMAINDER OF THE AREA...

High pressure of 1022 mb is centered near 31N131W. The pressure 
gradient between the area of high pressure and lower pressure in
the vicinity of the ITCZ is supporting moderate winds north of
the ITCZ, with seas in the 4-7 ft range. Light to gentle winds
and seas in the 5-7 ft range prevail elsewhere. High pressure
will continue north of the area with these general conditions
prevailing.
