...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A northwest to southeast ridge will prevail west of the area. 
This will support mainly gentle to moderate northwest breeze west
of the Baja Peninsula. Seas of 7 to 9 ft will propagate 
southeast across the waters north of 27N Wed through Thu, 
subsiding below 8 ft on Thu night.
   
Gulf of California: A surface trough over the northern Gulf of
California will support moderate locally fresh southwesterly 
winds through Thu morning. Light and variable winds are expected
across the southern gulf until late Thu before increasing to 
moderate to fresh. 

Gulf of Tehuantepec: Winds are expected to be light and variable 
through the upcoming weekend.    
  
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR... 

The monsoon trough will gradually shift southward this week, 
reaching 10N by Fri. Light to gentle southwest to west winds, and
3 to 5 ft seas will prevail S of the trough. Gentle to 
occasionally moderate offshore nocturnal winds will prevail near 
gap areas N of the trough.
  
REMAINDER OF THE AREA...
   
A surface ridge extends across the northern waters. Fresh to 
locally strong trades, and 7 to 10 ft seas, are observed across 
the tropics south of the ridge from 10N to 20N west of 127W. 
These conditions will gradually diminish through Thu. 

Northerly swell, with seas in the 8 to 9 ft range prevails north
of 26N between 124W and 135W. The swell will propagate southward
the next couple of days while subsiding. Seas associated to this
swell will subside below 8 ft Fri.
