support moderate to fresh winds, occasionally locally strong, 
over the northern Gulf of California through Tue night. 
Elsewhere, a moderate pressure gradient will support mostly 
gentle to moderate winds across the offshore waters of Mexico. 
Northerly swell NW of Guadalupe Island will subside below 8 ft 
tonight. Fresh to strong gap winds and building seas are expected
across the Gulf of Tehuantepec toward the end of the week.

AND WITHIN 750 NM OF ECUADOR...

Moderate to locally fresh winds and moderate seas prevail over 
and downstream the Gulf of Papagayo. Gentle to moderate winds are
found between the Galapagos Islands and Ecuador. Light to gentle
winds and moderate seas are noted elsewhere. 

For the forecast, moderate to fresh winds will pulse across the 
Papagayo region, with strong winds pulsing at night starting Tue
night. Moderate or weaker winds and moderate seas in SW swell 
are expected across the remainder of the waters through the 
period.  

...REMAINDER OF THE AREA...

Northerly swell has propagated into the northern waters, bringing
rough seas to the waters N of 28N between 120W and 132W. 
Elsewhere over the discussion waters, gentle to moderate winds 
and moderate seas prevail. 

For the forecast, the northerly swell will bring rough seas over
the waters off Baja California Norte north of 27N and east of 
135W through Tue. Southerly swell will build northward to 03N and
west of 105W starting Tue night. Meanwhile, seas may build to 8 
ft in the tradewind zone in the western waters late this week.
