...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure of 1033 mb centered north of the area near 36N138W
extends a ridge southeast to the Revillagigedo Islands. Moderate
to fresh winds prevail off the west coast of Baja California 
Norte while gentle to moderate winds prevail off the coast of 
Baja California Sur. Light to gentle winds prevail elsewhere over
the forecast waters. Seas in the 9-11 ft range prevail off the 
west coast of Baja California Norte, 7-8 ft off the coast of Baja
California Sur, 2 ft or less over the Gulf of California, and 
4-7 ft over the remainder of the forecast waters.
 
Seas will subside today and Sunday, decreasing to around 8 ft 
of the west coast of Baja California Norte. Another set of
northwest swell will build to the 10 to 12 ft range over this 
area on Monday, while seas off Baja California Sur will remain 
between 7 and 9 ft through the middle of next week. 

Looking ahead, a cold front will move across the Gulf of Mexico
late next week. High pressure building behind the cold front 
may help induce near gale to gale force winds in the Gulf of 
Tehuantepec area Thursday night into next Friday.

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

Light to gentle winds and seas in the 3-6 ft range will prevail 
over the forecast waters through the middle of next week.

High pressure prevails over the northern waters. The pressure 
gradient between the area of high pressure and the equatorial
trough is generating moderate to fresh winds over the tradewind 
belt. Seas within this area range between 8 and 11 ft as long 
period northwest swell mix with shorter period northeast wind 
waves. 

Another round of large NW swell will reach the NW part of the 
forecast area tonight. this swell will propagate southeastward 
through early next week. Seas associated with this swell event 
will peak near 13 ft over the northern waters Sunday before 
subsiding.
