...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: High pressure building into 
northeast Mexico in the wake of a cold front will lead to gale-
force gap winds in the Gulf of Tehuantepec tonight into early 
Tue morning. Seas will rapidly build and exceed 12 ft in this 
area late tonight. Conditions will improve Tue night as the high
pressure weakens and moves east.

Hurricane Center at website -

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough axis extends from 06N77W to 02N90W. The ITCZ
extends from 02N90W to 00N140W. Convection previously along the
monsoon trough has dissipated overnight.

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

See Special Features section above for information on a Gale 
Warning for the Gulf of Tehuantepec.

Moderate to fresh N winds are ongoing off Baja California and 
the Gulf of California, extending southward to Cabo Corrientes.
Seas in offshore waters southward to Jalisco and Colima are 8 to
11 ft, with 4 to 7 ft seas in the central and southern Gulf of
California, and 2 to 4 ft seas in the northern Gulf. Gentle 
breezes are noted farther south with 4 to 7 ft primarily in NW 
swell. 

For the forecast, rough seas in NW swell will continue offshore 
Baja California and the Revillagigedo Islands, before decaying 
early the week. Strong winds may pulse near the coasts of Baja 
California, Cabo Corrientes, and in the Gulf of California 
through tonight as another area of high pressure builds southward
from the southwest United States. Looking ahead, more gale force
gap winds may develop in the Gulf of Tehuantepec Thu. 

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

Light to gentle winds and seas of 3 to 5 ft prevail across the 
waters as a weak pressure pattern resides over the waters.
Moderate NW swell to the W and SW of the Galapagos Islands is
causing some 6 to 7 ft seas. 

For the forecast, over most waters gentle winds and slight to 
moderate seas will prevail early this week. Pulsing fresh to 
strong N to E winds will develop in the Gulf of Papagayo and Gulf
of Panama Mon night, then prevail at least through the middle of
the week. Elsewhere, rough seas generated by gale force winds in
the Gulf of Tehunatepec will impact areas well offshore 
Guatemala Mon and Tue. 

...REMAINDER OF THE AREA....

A 1023 mb high is centered near 28N137W, extending ridging 
through the eastern Pacific waters north of 20N. This pattern is 
supporting moderate to fresh trade winds west of 115W S of 20N 
extending to the ITCZ. Light to gentle breezes are noted 
elsewhere. Combined seas are 7 to 11 ft north of the ITCZ and 
west of 115W, primarily in NW swell. Combined seas of 5 to 7 ft 
persist elsewhere.

For the forecast, rough seas in excess of 8 ft will propagate 
southeastward through tonight while gradually decaying below 8 
ft. Moderate to fresh trade winds will prevail between 05N and 
25N west of 115W early this week. A cold front will move across 
the waters north of 20N today through Tue, leading to fresh N to
NE winds and large NW swell.
