...SPECIAL FEATURES....
Gulf of Tehuantepec Gale Warning: Northerly winds are funneling
through the Chivela Pass and supporting gale-force NNE winds in
the Gulf of Tehuantepec region. Gales will continue through this
evening, with seas peaking to 10 ft. Gales will likely resume
again Wed night as strong high pressure builds over Texas just N
of a surface trough over the western Gulf of Mexico. Seas in the
Tehuantepec region during this period will peak at 13 ft, mainly
on Thu night. Winds will quickly diminish below gale-force by
early Fri.
Please refer to the latest NWS High Seas Forecast issued by the
National Hurricane Center at the website:
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml, for more details.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 09N84W to 04N109W. The ITCZ
continues from 04N109W to beyond 06N140W. Scattered moderate
convection is from 03N to 08N between 91W and 95W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please, refer to the Special Features section above for details
on an ongoing Gale Warning for the Gulf of Tehuantepec.
A weak pressure gradient in the region continues to support
moderate to fresh NE winds and moderate seas in NW swell along
the Baja and SW Mexico offshore waters N of 24N. Light to gentle
NE winds prevail elsewhere. High pressure over the Great Basin
of the United States is supporting fresh to strong northerly
winds in the Gulf of California, with seas to 6 ft.
For the forecast, gale-force NNE winds in the Gulf of
Tehuantepec region will continue through this evening, with seas
peaking to 10 ft. Gales will likely resume again Wed night as
strong high pressure builds over Texas just N of a surface trough
over the western Gulf of Mexico. Seas in the Tehuantepec region
during this period will peak at 13 ft, mainly on Thu night. Winds
will quickly diminish below gale-force by early Fri. Fresh to
strong winds in the Gulf of California will continue through
tonight, gradually diminish to gentle to moderate speeds Wed
night, and then prevail mainly over the southern and entrance of
the Gulf through Sat night. Gentle to moderate NE winds are
forecast to develop across Baja California Sur Wed morning
reaching Baja Norte offshores by the weekend. Light to gentle
winds are expected elsewhere.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong NE to E winds and moderate seas to 8 ft are
ongoing in the Gulf of Papagayo. Moderate E winds associated with
this gap wind event extend to the outer offshore waters of
Guatemala and El Salvador where seas are 6 ft in NW swell. In the
Gulf of Panama, winds are moderate to fresh from the NNE and
seas are 3-4 ft. Light to gentle winds and slight to moderate
seas in mixed SW and NW swell are elsewhere between Ecuador and
The Galapagos Islands.
For the forecast, fresh to strong NE to E winds in the Gulf of
Papagayo will continue through Sat, likely increasing to near
gale-force on Wed morning as high pressure ridging builds over
the Caribbean. Rough seas are expected with this gap wind event.
Moderate to fresh easterly winds from the Papagayo gap wind
event will continue to propagate across the outer offshore waters
of Guatemala and El Salvador through Wed night. Pulsing fresh N
winds in the Gulf of Panama will diminish to moderate speeds on
Thu and to light to gentle speeds over the weekend. Otherwise,
light to gentle southerly winds between Ecuador and The Galapagos
Islands will reach moderate speeds Sat night.
...REMAINDER OF THE AREA...
A strong high pressure of 1035 mb located well N of area extends
a ridge across the forecast waters N of the ITCZ and W of 110W.
To the west of the Baja California offshore waters, a 1020 mb low
is analyzed near 28N128W with surface trough from 30N128W to the
low to 22N125W. Moderate to fresh winds and seas to 11 ft are
noted with the low/trough. N of 20N and W of 123W, fresh winds
and seas are 8 to 11 ft in northerly swell, along with.
Elsewhere, winds are gentle to moderate and seas are moderate.
For the forecast, the surface trough to the west of the Baja
California offshore waters will dissipate on Thu and then
surface ridging will dominate the subtropical waters through the
weekend. Northerly swell to the west of the surface trough will
gradually subside before decaying on Thu morning. Otherwise, a
surface trough is forecast to develop over tropical waters near
115W by the end of the week and then propagate westward
enhancing winds to fresh to locally strong speeds, and building
seas to 10 ft through Sat night.
