...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... 

The latest scatterometer data showed light to gentle winds off 
the coast of Baja California Norte. Mainly gentle to moderate NW
winds prevailed elsewhere across the open forecast waters, 
except off the coast of Cabo San Lucas, where fresh to locally 
strong winds prevailed. Light winds prevailed over the Gulf of
California. Over the open waters off Mexico, seas are mainly in 
the 4-6 ft range, reaching 7-8 ft just west of Guadalupe Island, 
in N swell. Seas over the Gulf of California are 3 ft or less.

High pressure west of Baja California will maintain gentle to 
locally moderate NW winds over the offshore waters through the 
weekend. Winds may briefly pulse to fresh to locally strong off 
Cabo San Lucas each late afternoon and evening for the next 
several days. Seas will subside below 8 ft off the waters west 
of Guadalupe Island tonight.

Northerly gap winds are expected to develop over the Gulf of 
Tehuantepec late Mon as the local pressure gradient tightens.

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

The latest scatterometer data indicated gentle to moderate
southerly flow across the forecast waters S of 06N, with light 
flow N of 06N. Seas are in the 5-8 ft range S of 07N, and 5-6 ft
N of 07N. 

Long period SSW swell over the far southern waters will begin to
slowly subside Sun through Mon.


REMAINDER OF THE AREA... 

High pressure of 1032 mb centered well N of the area near 
42N132W extends a ridge SE to just S of the Revillagigedo 
Islands. Moderate to fresh N to NE winds prevail over the waters 
N of 20N to the W of 125W, and gentle to moderate elsewhere N of
20N. Seas are in the with seas in the 8-10 ft range in northerly
swell N of 25N between 120W and 131W, and 5-7 ft elsewhere N of
20N. Gentle to moderate winds, with seas in the 4-7 ft range in 
mixed swell prevail elsewhere N of the ITCZ, except from 08.5N 
to 11.5N between 132W and 140W where seas are reaching near 8 ft.
The northerly swell will continue to bring seas of 8 ft or 
greater across the waters west of Guadalupe Island between 120W 
and 130W through the remainder of the weekend before subsiding
below 8 ft Mon.

Farther south, southerly swell will continue dominating the 
waters east of 120W through early next week. Latest altimeter 
data revealed 8-9 ft seas reaching as far north as 06.5N between 
91W and 106W. The swell will start to subside tonight, and fall
below 8 ft Sun.
