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

The ITCZ extends from 05N98W to 05N118W to 03N130W to 04N140W. 
Scattered moderate isolated strong convection was noted from 02N 
to 08N E of 86W. Scattered moderate convection was noted from 
02N to 07N between 120W and 140W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends west of the Baja California peninsula. The
pressure gradient between the ridge and a trough over the Baja
California peninsula is supporting fresh to strong winds west of
Baja California Norte. Gentle to moderate winds are noted over
the Gulf of California. Light to gentle winds prevail elsewhere.
Seas are in the 6-7 ft range off the coast of Baja California, 
and 4-5 ft over the remainder of the open waters off Mexico. Seas
are in the 1-3 ft range over the Gulf of California.

Fresh to locally strong NW winds will prevail over the Baja 
California Norte offshore waters through Sat. NW swell will move 
into the waters off Baja California Norte Fri, with seas building
to 10-11 ft by Sat night. Moderate to fresh SW to W winds are 
forecast over the Oaxaca adjacent waters Fri and Sat. 

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

Moderate to fresh winds, and seas of 4-6 ft prevail over the 
Gulf of Papagayo. Moderate winds, and seas of 5-6 ft, prevail 
over the Gulf of Panama. Light to gentle winds, and seas of 4-5 
ft, prevail elsewhere.

Moderate to fresh NE to E winds in the Gulf of Papagayo region 
will diminish below moderate speeds on Wed. Moderate to fresh N 
to NE winds in and downstream of the Gulf of Panama will continue
through early this evening before diminishing. Light to gentle 
winds will prevail across the remainder of the region through the
forecast period. 

REMAINDER OF THE AREA...

A ridge of high pressure prevails over the northern waters east 
of 130W. A surface trough extends from 30N134W to 22N140W. A 
weak pressure gradient prevails across the forecast waters, with 
gentle to moderate winds prevailing north of the ITCZ to near 20N
and west of 120W. Gentle to moderate winds are also noted N of 
20N between 115W and 125W. Light to gentle winds prevail 
elsewhere. Seas are in the 7-8 ft range over the waters N of 20N 
and west of 130W in subsiding NW swell. Seas of 5-7 ft prevail 
elsewhere. 

A weak pressure gradient will continue over the area through the
end of the week with little change in winds expected. High
pressure will start to build over the northern waters later this
week, strengthening tradewinds north of the ITCZ to near 15N and
west of 130W Fri into Sat. The NW swell will subside below 8 ft 
today. Northerly swell will enter to northern forecast waters 
E of 125W Fri. Seas over this area will build to near 11 ft by 
Sat night.
