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

The monsoon trough extends from 16N97W to 07N107W. The ITCZ
extends from 07N107W to beyond 04N140W. Scattered moderate

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Latest scatterometer data depicts fresh to locally strong winds
off the coast of the Baja California peninsula, with gentle to
moderate winds prevailing elsewhere off the coast of southwest
Mexico. Winds are light and gentle over the Gulf of California.
Seas are in the 6-7 ft range off the coast of the Baja California
peninsula, 4-6 ft over the remainder of the offshore waters off
southwest Mexico, and 1-3 ft over the Gulf of California. A 
fresh set of northwesterly winds will usher in seas to 9 ft off 
the coast of Baja California Norte later today. Seas over this
area will subside below 8 ft by the weeks end. Elsewhere winds
and seas will remain below advisory criteria. 

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

Gentle to moderate winds prevail over the offshore zones off the
coast of Ecuador while light to gentle winds prevail elsewhere.
Seas over the offshore wavers off the coast of Ecuador are in the
6-8 ft range in southwesterly swell while seas in the 3-5 ft
range prevails elsewhere. The southwesterly swell continue to
propagate and reach the offshore waters of Central America today,
with seas in the 5-7 ft range prevailing through the weekend. 

REMAINDER OF THE AREA... 

High pressure of 1031 mb centered nw of the area near 34N141W 
extends a ridge southeastward to near the Revillagigedo Islands. 
Moderate to fresh trades prevail between the ridge and ITCZ west 
of 120W. Seas in the trade-wind belt are mainly 6 to 8 ft. Winds 
will diminish through weeks end with seas subsiding. By this 
weekend, gentle to moderate winds with seas in the 5-6 ft range 
will prevail.
