...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

...SPECIAL FEATURES...

Gulf of Tehuantepec: High pressure that prevailed north of the 
area has shifted eastward, loosening the pressure gradient. This
has helped for winds to diminish below gale force. Winds over the
SW Gulf will veer today. This will further decrease winds funneling
through the Chivela pass into the Gulf of Tehuantepec. This will 
bring an end to this latest gap wind event, with winds 
diminishing below 20 kt by this evening. Another gap wind event 
may occur across the Gulf of Tehuantepec Thu, though winds are 
expected to remain below gale force. 

A weak pressure pattern will prevail through the middle of this 
week producing mainly gentle to moderate NW-N winds and seas of 4
to 7 ft. 

Gulf of California: Mainly light to gentle winds will prevail 
over much of the gulf the next several days with the excpetion of
gentle to moderate winds over the northern gulf today through 
Tue.

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

Gulf of Papagayo: moderate to fresh NE-E winds will prevail. 

Gulf of Panama: moderate to fresh N-NE winds will prevail. 

Elsewhere, gentle to moderate offshore flow is generally 
expected N of 09N through Tue, while light and variable winds are
forecast S of 09N.

REMAINDER OF THE AREA... 

A weak pressure pattern will prevail over the forecast area. This
will maintain mainly gentle to moderate winds. With winds 
remaining below 20 kt, and no long period swell events expected, 
seas will remain less than 8 ft during this period.
