...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

Large long period NW swell with seas in excess of 8 ft continues
to prevail over the offshore waters off the Baja California 
peninsula, through the Revillagigedo Islands, to the coast of 
Mexico west of 100W. Reinforcing swell with seas in excess of 12
ft, associated with a cold front moving across the region, will 
impact Baja California Norte and Guadalupe Island Fri, reaching 
to off the norther coast of Baja California Sur by Sat. The swell
will decay to below 8 ft over all but Baja California Norte by 
early next week.

In the Gulf of California, strong west gap winds will follow the
cold front into the northern Gulf late tonight into early Fri.

Looking ahead, the next gap wind event over the Gulf of
Tehuantepec is expected to start next Tuesday, with winds to near
gale force.

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

Elsewhere, the monsoon trough will remain between 08N and 11N 
during the rest of the week. Gentle to moderate winds will
prevail on either side of the trough, with seas in the 5 to 7 ft
range. 

REMAINDER OF THE AREA...

A cold front extends from northern Baja California Norte to 
23N140W. The front will continue southeastward through Baja
California and the Gulf of California, moving east of the area 
late Friday. Large, long period NW swell is impacting the 
forecast waters, with seas greater than 8 ft noted over much of 
the area W of 110W. Seas will peak near 18 ft over the waters N 
of 28N Friday before beginning to subside. Seas will subside 
below 8 ft over much of the forecast waters by early next week. A
new set of NW swell is forecast to move into the far NW waters 
late Mon.
