Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.
Based on 1200 UTC surface analysis and satellite imagery through
1500 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 08N82W to 07N90W to 02N100W TO
03N110W. The ITCZ continues from 03N110W to 05N130W to beyond
04N140W. Convection is limited.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Strong high pressure of 1036 mb located well NW of the area near
38N138W extends a ridge southeastward toward Baja California Sur
and the Revillagigedo Islands. The pressure gradient between
this ridge and a surface trough over NW Mexico is producing
moderate to fresh NW to N winds offshore the Baja California
waters per latest scatterometer data. Seas are 4 to 6 ft within
these winds, except 6 to 9 ft in NW swell across the outer
offshore waters N of Punta Eugenia. Light winds prevail across
the Gulf of California where seas are slight. Elsewhere to the
east, a weak pressure gradient is leading to mainly gentle winds
across the waters, except fresh to strong N winds in the
immediate Gulf of Tehuantepec. Mainly moderate seas prevail
offshore southern and SW Mexico, as well as across the remainder
of the waters.
For the forecast, high pressure well NW of the area will build
modestly over the Baja California waters through early Fri and
will tighten the pressure gradient there, bringing fresh to
strong NW winds during that time. Associated rough seas in
northerly swell will persist off Baja California Norte into the
weekend. Weak low pressure is expected to form just offshore
Baja California Norte Fri through Sat, then shift slowly eastward
into early next week. This will push the strong NW winds
offshore and W of 120W, and will relax the pressure gradient over
the offshore waters of Baja California, leading to improving
marine conditions through the weekend. Gentle to moderate winds
are expected in the Gulf of Tehuantepec through the forecast period.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong NE to E gap winds are across the Papagayo
region, with moderate to locally fresh N gap winds across the
Gulf of Panama. Seas are 5 to 7 ft downwind of Papagayo and 3 to
5 ft downwind of the Gulf of Panama. Elsewhere, winds are light
to gentle with slight to moderate seas of 5 ft or less in SW
swell.
For the forecast, pulsing fresh to strong winds are expected in
the Papagayo region through the weekend and into early next week
as high pressure remains N of the region. Moderate gap winds
across the Gulf of Panama will pulse to locally fresh at night,
otherwise mainly light to gentle winds will prevail elsewhere
through the weekend. Looking ahead, significant cross-equatorial
SW swell is expected to reach the waters offshore Ecuador to the
Galapagos Islands by Mon of next week.
