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

A surface trough extends from 08N82W to 05N99W. The ITCZ 
continues from 05N89W to 01N103W to 05N120W to 02N131W to beyond
03N140W. Scattered moderate convection is noted from 01N to 10N 
between 115W and 122W and from 03N to 07N between 138W and 140W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Gentle to moderate NW winds prevail west of Baja California Norte
while moderate to fresh winds are noted west of Baja California
Sur. Fresh to locally strong winds are over the Gulf of
Tehuantepec. Gentle to moderate winds are noted over the Gulf of
California, with mainly light to gentle winds elsewhere. Seas 
are 8 to 9 ft west of Baja California, 2 to 4 ft in the Gulf of 
California, and 4-6 ft elsewhere. 

Winds in the southern half of the Gulf of California will become
fresh to strong through Sun. Strong to near gale-force winds are
expected near Cabo Corrientes Sat night. Gentle to moderate 
winds will prevail elsewhere over the offshore waters west of 
southern Mexico.

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

See the Special Features section above regarding the potential
for heavy rainfall along and near the coast of Western Colombia.

Fresh to strong NE to E winds are noted in the Papagayo region. 
Moderate to fresh winds are in and downstream of the Gulf of 
Panama. Light to gentle winds prevail elsewhere. Sea heights are 
generally 3 to 5 ft, except 6 to 8 ft downwind from the Gulf of 
Papagayo. Fresh to strong NE winds will continue to pulse across 
the Papagayo region into Mon, with highest winds expected at 
night. Seas associated with these winds will be 7 to 9 ft. Fresh 
north winds in the Gulf of Panama will pulse at night into Mon.

prevail elsewhere through Mon.

REMAINDER OF THE AREA...

High pressure of 1030 mb is centered north of the area near
33N136W, The pressure gradient between this area of high pressure
and lower pressure in the vicinity of the ITCZ is supporting 
fresh to locally strong winds north of the ITCZ to near 25N and 
west of 120W. Seas in this area are in the 8-11 ft range. NW 
swell covers much of the waters N of 03N and W of 110W. The swell
will slowly subside the next few days. Another cold front will 
reach NW waters on Sat, and extend from 32N130W to 25N140W Sun. 
Large NW swell associated with the front will move through the 
northern waters Sat night through Mon. The front will usher in 
another set of NW swell, which will peak near 13 ft over the NW 
waters Sun.
