...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
High pressure prevails west of the Baja California peninsula
while a trough extends across the western Gulf of California.
Winds are in the fresh to strong range off the coast of Baja 
California Norte, and moderate to locally fresh off the coast of 
Baja California Sur. Light to gentle winds prevail elsewhere. 
Seas are in the 7-8 ft range off the coast of Baja California 
Norte north of 28N, 5-6 ft elsewhere off the coast of Baja 
California, 1-2 ft over the Gulf of California, and 4-5 ft off 
the remainder of the open waters. Winds will pulse to strong off 
the coast of Baja California the next few nights. Northwest swell
will propagate into the offshore waters off the coast of Baja 
California Norte Sun. The swell will propagate southward to near 
25N while subsiding. Seas will fall below 8 ft by midweek. Fresh 
to locally strong SW to W winds are forecast north of 29.5N in 
the Gulf of California tonight through late Sun. Low pressure 
will meander south of Tehuantepec and southwest Mexico the next 
couple of days bringing active weather across these waters as 
well as portions of southern Mexico.

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

Gentle to moderate westerly winds and 4 to 6 ft seas are 
expected north of 07N...and moderate southerly winds with 5 to 7
ft seas forecast south of 07N through Wednesday night.

REMAINDER OF THE AREA...

A stationary front extends across the northwest waters. Weak high
pressure of 1018 mb centered near 25N130W extends a ridge southeast
to near 15N113W. Moderate to locally fresh northeast winds 
prevail north of the stationary front, while gentle to moderate 
winds prevail elsewhere. Seas are in the 4-6 ft range. The front 
will weaken today and dissipate by Sun. High pressure will build 
over the northern waters as the front dissipates. This will 
freshen winds north of the ITCZ early this week with seas 
building to 5-7 ft.
