...SPECIAL FEATURES... 

Heavy Rainfall potential in Western Colombia: Heavy rainfall is 
possible along and near the coast of Colombia at times, with 
enhanced precipitation possible through the end of the week. 
Mariners near the coast of Colombia are advised to be aware of 
the possibility of reduced visibility from heavy rain and strong 
thunderstorms. Please refer to forecasts and bulletins issued by 
your National Meteorological Service for more details.

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

A surface trough extends from 07N77W to 04N81W to 02N97W. The 
ITCZ continues from 02N97W to 02N113W to 04N132W to 03N140W. 
Scattered moderate isolated strong convection is noted from 04N 
to 07N between 127W and 138W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Fresh to strong northerly winds will prevail in the Gulf of 
Tehuantepec overnight. After that, light to gentle variable 
winds will prevail across the area through Mon. Offshore seas 
will subside to 4 to 5 ft on Thu. Fresh to strong NW winds 
currently north of Cabo San Lazaro will spread southward to Cabo
Corrientes, including the southern Gulf of California, through 
the weekend. Large NW swell west of Baja California will begin to
decay Thu and Fri, allowing the seas to subside to 8-9 ft, except
in the area of fresh to strong winds.

A decaying cold front will reach Baja California Norte overnight,
with winds in the northern Gulf of California becoming SW-W and 
increasing. Highest winds will be near gaps in the coastal 
terrain, where fresh to strong winds are possible. Winds in the 
southern half of the Gulf of California will become fresh to 
strong Fri through Sun. Gentle to moderate winds will prevail 
elsewhere over the offshore waters west of southern Mexico.

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

See the Special Features section above regarding the potential
for heavy rainfall along and near the coast of Western Colombia.

Fresh to strong NE winds will continue to pulse across the 
Papagayo region through the weekend, with highest winds expected 
at night. Seas associated with these winds will be 7 to 9 ft. 
Fresh north winds in the Gulf of Panama will pulse at night 
through the weekend. Light to gentle winds, with seas in the 3 
to 6 ft range, will prevail elsewhere through Mon.

REMAINDER OF THE AREA...

A cold front stretches from 32N121W to 27N130W to 32N140W. The
cold front will weaken and extend from 32N114W to 23N130W to
24N140W on Thu, then dissipate Thu night. High pressure in the
wake of the cold front will shift eastward through Fri night, and
support fresh to strong trade winds over a large portion of the
forecast area, from roughly 09N to 24N west of 124W, through
early Sat. Seas in this area will remain in the 8-12 ft range. 
The NW swell over the northwest part of the area will gradually 
shift east-southeast through Fri. The swell will mix with wind 
waves in the area of fresh to strong trade winds. A cold front
will reach the NW waters on Sat, and extend from 32N125W to
26N140W on Sun. Large NW swell associated with the front will 
move through the northern waters Sat night through Mon.
