...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Building ridging over NE 
Mexico supports strong to gale-force northerly winds and rough 
seas to 13 ft across the Gulf of Tehuantepec. Gale force winds 
will continue through early Tue morning with seas building to 
around 15 ft tonight into early Tue. Gusty winds to near storm 
force may occur. Seas generated from this gap wind event will 
spread well away from the Tehuantepec area, with seas 8 ft or 
greater reaching as far south as 10N and 100W tonight into Tue. 
Winds and seas will quickly diminish Tue. Please read the latest 
High Seas Forecast issued by the National Hurricane Center at 
website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more
details.

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

A surface trough extends from 05.5N80W to 03.5N97W. The ITCZ 
stretches from 03.5N97W to beyond 07N140W. Scattered moderate 
convection is observed from 03N to 06N between 83W and 101W, and
from 02.5N to 14N between 116W and 131W.

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

Please refer to the Special Features section for details on the 
Gulf of Tehuantepec Gale Warning.

Aside from the Gale Warning in the Gulf of Tehuantepec, a weak 
NW to SE ridge extends along the outer offshore waters boundary 
with troughing over central Mexico. This pattern supports 
moderate to locally fresh NW-N winds from Cabo San Lazaro 
northward offshore Baja California. Winds are mainly light to 
gentle across the remainder of the waters away from the Gulf of 
Tehuantepec, including in the Gulf of California. Seas are mainly
5-6 ft away from the Gulf of Tehuantepec in a mix of S and NW 
swells, with seas 3 ft or less in the Gulf of California away 
from the entrance.

For the forecast, other than the Gale Warning in the Gulf of 
Tehuantepec, winds will pulse there to fresh to strong once the
gale ends on Tue. Moderate to locally fresh NW winds and 
moderate seas are expected off Baja California through Thu night.
Winds may pulse to strong N of Punta Eugenia at times through Thu
evening. Moderate to fresh SW winds may develop in the northern 
Gulf of California Fri night ahead of a cold front approaching
Baja California Norte, then to fresh to strong Sat night. Winds 
will be moderate or weaker elsewhere through the next several
days. Little change in seas is forecast through the week.

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

A building ridge over the NW Gulf of America forces moderate 
easterly winds across the Gulf of Papagayo region. Seas in this
region are around 5 ft. Farther east, moderate N-NE winds and 
3-4 ft seas are present in the Gulf of Panama. Light to gentle 
winds and moderate seas dominate the remainder of the offshore 
forecast waters. 

For the forecast, fresh to locally strong gap winds are expected
during the nighttime and early morning hours in the Papagayo 
region and downwind to about 90W through the forecast period. 
Moderate to locally fresh northerly winds are forecast in the 
Gulf of Panama through the week. The ongoing gap wind event in 
the Tehuantepec region will produce seas to 9 ft in the far 
offshore waters of Guatemala tonight through Tue. Light to gentle
winds and moderate seas will prevail elsewhere.

...REMAINDER OF THE AREA...

A deep upper level trough continues to produce abundant 
cloudiness and some showers over the W-central and northern 
waters, extending from S of the Hawaiian Islands northeastward to
Baja California and into the SW United States. Elsewhere at the 
surface, a weak high pressure system over the northern waters 
with 1022 mb high pressure centered near 33N127W dominates the 
remainder of the basin. Moderate to locally fresh easterly winds 
are occurring from roughly 09N to 16N and W of 110W, highest in 
deep convection along the ITCZ which is described more above. 
Seas in these waters remain at 6 to 7 ft. Elsewhere, moderate or
weaker winds and moderate seas are prevalent.

For the forecast, a weak cold front is north of the area. Seas 
will briefly build to 9 ft ahead the front tonight and Tue 
before subsiding. Continuing high pressure will support moderate 
to locally fresh easterly winds and moderate to locally rough 
seas across the trade wind zone into the middle of the week, 
supporting seas to around 7 ft. Seas will build to around 8 ft in
NE swell from a Gulf of Tehuantepec gale force gap wind event to
near 10N100W tonight through Tue night. Moderate to fresh winds 
will accompany those seas. Seas may build to around 8 ft in 
southerly swell near 03.4S by the end of the week.
