...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: Building ridge across the
eastern slopes of the Sierra Madre Mountains in Mexico will
force the next gap wind event in the Gulf of Tehuantepec. Winds
are forecast to increase to 20 to 30 kt, with seas building to 8
ft by Sun night. Then, winds will further increase to gale force
by Mon morning, with seas building to 12 or 13 ft on Mon night.
Gusty winds to near storm force may occur. These marine
conditions are forecast to persist through Tue morning. 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 11N Mon night into Tue.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 08N83W to 06N98W. The ITCZ
stretches from 06N98W to 05N125W to beyond 04N140W. As is
typical for this time of the year, a second ITCZ is located south
of the Equator and runs from 08S87W to beyond 04S140W. Scattered
moderate convection is observed from 01N to 08N and west of
117W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A robust high pressure north of the area supports moderate to
locally fresh northerly winds in the offshore waters of Baja
California, especially north of Cabo San Lazaro. Seas in these
waters are 6-8 ft. Moderate to locally fresh NW winds and seas of
2-5 ft are evident in the Gulf of California. In the remainder
of the Mexican offshore waters, including the Gulf of
Tehuantepec, light to gentle winds and moderate seas in south
swell prevail.
For the forecast, a Gale Warning is in effect for the Gulf of
Tehuantepec. Please, see the Special Features section for more
details. Meanwhile, NW swell producing locally rough seas off
Baja California Norte will diminish tonight. Gentle to moderate
winds and slight seas will prevail in the Gulf of California
tonight through midweek next week. Moderate to locally fresh NW
winds and moderate seas are expected off Baja California through
the forecast period.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
High pressure north of the Caribbean is supporting moderate to
fresh easterly trade winds across the Gulf of Papagayo region.
Seas in these waters are 4-5 ft. Farther east, moderate to
locally fresh northerly winds and moderate seas are present in
the Gulf of Panama. Meanwhile, light to gentle winds and moderate
seas dominate the remainder of the offshore forecast waters.
For the forecast, fresh to strong gap winds are expected during
the nighttime and early morning hours in the Papagayo region and
downwind to about 88W through the forecast period. Moderate to
fresh northerly winds are expected in the Gulf of Panama tonight.
Then, mainly gentle to moderate N winds are expected through the
middle of the next week. Residual southerly swell will maintain
moderate seas between Ecuador and the Galapagos Islands through
this weekend while gradually subsiding.
...REMAINDER OF THE AREA...
The combination of a weak surface trough and strong upper level
winds continue to support abundant cloudiness and possible
showers over the western waters. At the surface, a broad
subtropical ridge forces moderate to fresh easterly winds and
seas of 6-8 ft north of the ITCZ and west of 110W. Elsewhere,
moderate or lighter winds and moderate seas are prevalent.
For the forecast, a ridge will support moderate to locally fresh
easterly winds and moderate to locally rough seas across the
trade wind zone into the middle of next week. A cold front is
forecast to reach 30N140W by Sun night, and extend from 30N137W
to 24N140W by Mon morning. Gentle to moderate winds are forecast
on either side of the front. Seas will briefly build to 9 ft
behind the front Mon night into Tue.
