...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Moderate to fresh winds prevail over the Gulf of California, with
slight seas. Moderate or weaker winds, and moderate seas, prevail
over the open waters off Mexico. 

For the forecast, the pressure gradient between high pressure NW
of the area and low pressure over the Colorado River Valley will
support moderate to fresh winds over the northern Gulf of 
California through tonight. Elsewhere, a moderate pressure 
gradient will support mostly gentle to moderate winds across the 
offshore waters of Mexico. Fresh to strong gap winds and building
seas are expected across the Gulf of Tehuantepec toward the end 
of the week. 

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
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 the second 
half of the week. 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 is 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 rough seas in northerly swell will subside
today. Southerly swell will build northward to 03N and west of 
105W starting tonight. Seas may build to 8 ft in the tradewind 
zone in the western waters late this week.
