...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge extends across the offshore forecast waters off Baja
California to near the Revillagigedo Islands. Aside from the
gale conditions in the Gulf of Tehuantepec, generally gentle to
moderate winds persist. Gale force winds are currently blowing
across the Gulf of Tehuantepec. Please, see Special Features
section for details.

Long period NW swell will continue to propagate SE across much of
the forecast waters. Seas 8-10 ft associated with this swell
event are affecting the waters W of Baja California, and the
Revillagigedo Islands. Another set of reinforcing NW swell will
enter the waters of Baja California Norte Sunday, with overall
combined seas reaching up to 13 ft. Wave heights will subside as
the swell pushes south, but 8 to 10 ft seas are likely in the
offshore waters west of 100W through early next week.

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

Fresh to locally strong gap winds is likely tonight into early
Sunday morning in the Gulf of Papagayo. Otherwise, light to
gentle winds will prevail over the waters north of 10N, with
moderate to fresh winds south of 10N. Seas of 4-6 ft will
persist across the region into the middle of next week,
eventually with a mix of northwest and southerly swell.

REMAINDER OF THE AREA...

Strong southerly winds will precede a strong cold front that
will pass to the southeast of 30N140W on Monday, but stall and
weaken over the NW waters from 30N132W to 22N140W by Tuesday,
before becoming diffuse through mid week.

Long period northwest swell with seas of 8 to 13 ft dominates the
waters generally north of 10N and west of 125W. This will
overtake the region mainly north of 08N and west of 105W
tonight, with a reinforcing set of long period northwest swell
moving into the area through Sunday. A set of long period
northwest swell will pass 30N140W on Monday with seas up to 20
ft across the NW waters on Tuesday.
