...SPECIAL FEATURES...

Gulf of Tehuantepec Gale Warning: Strong high pressure anchored=20
by a 1032 mb high centered over southern Texas extends across=20
the Gulf of Mexico. A tight pressure gradient between the high=20
pressure and the equatorial trough in the eastern Pacific is=20
supporting strong gale-force winds with seas to 20 ft. Winds are
expected to drop below gale-force by early Sun afternoon.
However, fresh to strong winds will continue across the
Tehuantepec region through Mon evening when the next gale-force
gap wind event is forecast to begin. These winds will rapidly
reach speeds of 45 kt with seas to 13 ft building to 18 ft on
Tue. Winds for this second gap wind event are forecast to drop
below gale-force by Wed afternoon. Mariners are urged to stay=20
tuned to future forecasts that will highlight details regarding=20
this ongoing event. Please read the latest High Seas Forecast=20

ITCZ continues from 04N97W to 07N108W to 09N120W. There is no
significant convection associated with either the trough/ITCZ.
However, there are two surface troughs west of the ITCZ that are
generating scattered moderated convection from 11N to 18N between
111W and 125W, and from 09N to 17N between 127W and 137W.=20

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Please see the Special Features section above for information on
an ongoing Gulf of Tehuantepec gale-force gap wind event.

Moderate to fresh NW winds are along the Gulf of California with
seas of 3-4 ft. Gentle to moderate northerly winds are noted=20
along the Baja California peninsula offshore waters all the way
to the region of Jalisco with seas to 5 ft. Light to gentle=20
variable winds prevail across the rest of the SW Mexican offshores.

For the forecast, the storm-force winds in the Gulf of=20
Tehuantepec will diminish this evening. Gale-force winds are
expected to persist through Sun afternoon. Meanwhile, the fresh=20
to strong winds across the Gulf of California will end by this=20
evening. Gentle to moderate winds will prevail across the region
tonight into Sun. Moderate to fresh winds can be expected for=20
the Gulf of California and off the coast of Jalisco Mon into Tue.
The next gale force gap winds for the Tehuantepec region is=20
forecast to begin Mon night and continue through Wed morning.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and=20
WITHIN 750 NM OF ECUADOR

Fresh to strong NE gap winds are in the Papagayo region with seas
4-6 ft. Moderate N winds are noted in the Gulf of Panama with=20
seas to 4 ft. Light to gentle winds are elsewhere. Seas of 2-4=20
ft in S to SW swell are noted outside of the Gulfs of Papagayo=20
and Panama. Showers are moving south of a trough extending across
the area, from 02N to 05N between 79W and 84W.=20

For the forecast, fresh to strong NE winds in the Papagayo region=20
are expected to reach near gale-force speeds tonight. Strong
winds will persist across the area through Mon morning, and=20
pulse at night Mon night through Thu. Winds will pulse fresh to
locally strong tonight in the Gulf of Panama, then pulse to=20
fresh speeds at night through Thu. Elsewhere, light to gentle=20
winds will prevail across the Central American and equatorial=20
waters through Wed. Swell generated from an ongoing storm-force=20
gap wind event in the Gulf of Tehuantepec will produce large seas
over the Guatemala and El Salvador offshore waters this weekend.

REMAINDER OF THE AREA

Ridging from a 1037 mb high north of the area extends across the
northern portions of the forecast waters. The pressure gradient
between the high pressure with the lower pressure along the ITCZ
is giving way to fresh to strong winds N of the ITCZ to 26N and=20
W of 123W. Seas are 8-10 ft within N to NE swell. Gentle to=20
moderate winds and seas of 5-6 ft are present elsewhere over the=20
area.=20

For the forecast, the area of high pressure will remain north of
the area the next several days. This will maintain an area of=20
fresh to strong NE trades over the waters from 10N to 25N and=20
west of 120W. The winds will start to diminish slowly by Tue=20
