...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure is building over the Pacific waters west of the
Baja California peninsula, freshening winds off the coast of
Baja California Norte. Light winds prevail elsewhere over the
Pacific waters, with light to gentle winds over the Gulf of
California. Seas are 6-8 ft in the Pacific waters north of 28N
near Baja California, 4-6 ft elsewhere over the Pacific waters,
and 2 ft or less in the Gulf of California. High pressure will
build southward over eastern Mexico Thursday, and increase winds
in the Gulf of Tehuantepec, which will reach gale force Thursday
night, and continue through Saturday night. Large long period
northwesterly swell will build seas to 8-12 ft Friday off the
coast of Baja California Norte. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND

6 ft range prevail north of 10N, with 5-7 ft seas south of 10N.
These general conditions will prevail through Saturday.

REMAINDER OF THE AREA...

the ITCZ to 20N west of 120W, with seas 8-10 ft range in this
area. Gentle to moderate winds and 5-8 ft seas prevail elsewhere
