...SPECIAL FEATURES...

Significant Swell: Very rough seas in excess of 12 ft extend 
behind a cold front N of a line from 28N115W to 23N125W to 
30N135W, including waters just offshore Baja California Norte. 
Peak seas of 15 to 17 ft are along 30N between 118W and 123W. 
These seas will propagate SE and E today while gradually 
subsiding, and fall below 12 ft this evening. Seas will continue
to diminish below 8 ft from west to east this weekend.

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

The monsoon trough axis extends from 09N84W to 02N104W. The ITCZ
continues from 02N104W to 00N130W, then goes S of the Equator. 
Scattered moderate convection is noted south of 06N and E of 
104W.

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

See the Special Features Section for details on the Significant 
Swell impacting the waters offshore of Baja California.

A cold front extends from 29N112W across Baja California to
23N120W. Gales have ended behind the front, but strong N winds
are still impacting portions of the far northern Gulf of
California. Elsewhere, mainly fresh NW to N winds dominate waters
behind the front. Fresh NE winds are present ahead of the front
southward to the Revillagigedo Islands and Cabo Corrientes. Seas
in these waters are 7 to 10 ft. For the remainder of waters
further south, gentle to moderate winds and seas of 4 to 7 ft
prevail. 

For the forecast, fresh to strong NW winds will occur offshore 
Baja California and in the Gulf of California today. Rough seas 
associated with the aforementioned cold front will propagate 
southeastward through the weekend, reaching offshore of 
southwestern Mexico by early Sat. Looking ahead, gale force 
winds will be possible in the Gulf of Tehuantepec Sun night into 
early next week. 

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

Mainly gentle winds with seas of 3 to 5 ft in SW swell prevail.
Pulses of moderate gap winds are ongoing in the gulfs of Papagayo
and Panama. Convection in the area is associated with the 
monsoon trough and described in the above section.

For the forecast, gentle to moderate winds and slight to 
moderate seas will prevail across the waters through this 
weekend. Pulsing fresh to locally strong winds look to develop 
in the Gulf of Papagayo and Gulf of Panama early next week. 
Elsewhere, rough seas generated by gale force winds in the Gulf 
of Tehunatepec will impact areas well offshore Guatemala early 
next week. 

...REMAINDER OF THE AREA....

See the Special Features Section for details on the Significant 
Swell that is currently impacting the waters north of 24N.

A cold front moving through the NE waters extends from 29N112W 
to 23N120W, with fresh N winds behind the front. Outside the 
significant swell as described above under Special Features, 
rough seas associated with the cold front are progressing 
southeastward, with seas in excess of 8 ft noted NW of a line
from 22N116W to 13N132W. Elsewhere, broad ridging covers much of
the open waters, extending from a 1031 mb high centered near 
28N149W. Fresh NE winds are occurring along the periphery of the
ridge, from north of the ITCZ to 20N, generally west of 115W. 
Seas of 8 to 10 ft are noted in this region, with the highest 
seas occurring near 10N140W. Otherwise, gentle to locally 
moderate winds and seas of 4 to 7 ft prevail across the remainder
of the waters. 

For the forecast, the aforementioned cold front will progress 
southeastward through today, producing fresh NW winds and rough 
seas behind it. Farther south, moderate to fresh trade winds and 
rough seas of 8 to 10 ft will prevail from 05N to 20N and west of
115W into early next week as high pressure drifts eastward. 
Locally strong winds and seas to 11 ft are possible west of 135W 
today. Looking ahead, another cold front will move into NW waters
Sat night into Sun, bringing fresh N to NE winds and very rough
seas behind it N of 25N and W of 125W through Mon.
