...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Fresh to near gale force N to 
NE gap winds in the Gulf of Tehuantepec will pulse through Mon 
night, except for gale-force northerly winds forecast to develop 
Sat through Sun morning, then again briefly Sun night. Seas will
become rough to very rough during the period of gale-force 
winds, peaking around 15 ft by early Sun. Please read the latest 
HIGH SEAS FORECAST issued by the National Hurricane Center at 
website

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

A surface trough extends from 08N78.5W to 04N95W. The ITCZ 
extends from 04N95W to 02N114W to 05N125W to beyond 04N140W. 
Scattered moderate isolated strong convection is noted from 06N
to 09N between 114W and 114W, from 10N to 11.5N between 112W and
114W, and from 05N to 08N between 136W and 140W.

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

Please see SPECIAL FEATURES above for more on an upcoming Gulf of
Tehuantepec gale-force gap wind event. 

Fresh to strong N winds prevail in the Gulf of Tehuantepec, 
along with 4-6 ft seas. Moderate to locally fresh winds are noted
near Punta Eugenia and also near Cabo San Lucas. Elsewhere, 
light to gentle winds, and slight to moderate seas are noted,
except locally rough seas well offshore Baja California Norte.

For the forecast aside from the Gulf of Tehuantepec, moderate to
locally fresh SE-S winds will pulse in the Gulf of California Sun
into Sun night. Elsewhere, light to gentle winds through Wed 
night, pulsing to moderate to fresh near Baja California Norte, 
near Cabo San Lucas, and near Cabo Corrientes at times. Slight to
moderate seas will prevail over the waters away from the Gulf of
Tehuantepec.

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

Fresh to strong NE-E winds prevail over the Papagayo region. In 
the Gulf of Panama, moderate N-NE winds are noted. Elsewhere, 
light to gentle winds and slight to moderate seas prevail.

For the forecast, in the Gulf of Papagayo, fresh to strong NE 
winds will pulse through early Wed reaching downwind to 92W, 
with moderate to locally rough seas. Moderate to fresh winds will
pulse in the Gulf of Panama with moderate seas through Tue 
night. Rough seas will build well offshore western Guatemala by 
early Sun through Sun night due to a developing Gulf of 
Tehuantepec gale-force gap wind event. Gentle breezes and slight 
to moderate seas will prevail elsewhere through the forecast 
period. Looking ahead, large SW swell will build rough seas from
Ecuador offshore to the Galapagos Islands by mid-week.

...REMAINDER OF THE AREA...

A low pressure area is NW of the area. Outer associated fresh to
locally strong E-SE winds and rough seas are near the NW waters 
close to 30N140W. Rough seas in northerly swell are N of 28N
between 118W and 128W. Gentle to moderate winds and moderate 
seas are found over the remainder of the discussion waters. 

For the forecast, fresh to locally strong mainly SE winds will
prevail near 30N140W into tonight until the low NW of the area 
lifts N while weakening. Associated rough swells over the far NW 
and N-central waters will linger through early Sat before 
subsiding. Rough seas from a developing gale-force gap wind event
in the Gulf of Tehuantepec will spread SW and impact the waters 
roughly N of 07N and E of 106W Sun through Mon. Fresh to strong 
winds will pulse across these waters as well extending downwind 
from the Tehuantepec event. Elsewhere, gentle to moderate winds 
will prevail over the open waters. Moderate seas will prevail 
otherwise into early Sun across the open waters. Rough seas in 
southerly swell may impact the waters S of the Equator mid-week.
