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 0000 UTC surface analysis and satellite imagery through
0300 UTC.
...TROPICAL WAVES...
The southern portion of a tropical is along 82W N of 04N. It is
moving westward at 10 to 15 kt. No deep convection is presently
occurring with this wave.
A tropical wave has its axis along 107W from 01N to 14N moving
westward near 10 kt. Scattered moderate convection is seen from
04N to 14N between 98W and 114W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough axis extends from 09N82W to 11N98W to 11N114W
to 09N120W to 09N130W to 07N140W. Scattered moderate to isolated
strong convection is within 180 nm south of the trough between
126W-132W, also within 60 nm north of the trough between
118W-120W and between 130W-135W. Scattered moderate convection
is within 60 nm south of the trough between 95W-99W and from 04N
to 09N between 109W-115W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A broad surface ridge extends into the region to just NW of the
Revillagigedo Islands. The pressure gradient between the ridge
and a surface trough along the Gulf of California is producing
moderate to locally NW to N winds across the Baja California
offshore waters. NW swell continues to produce seas to 8 ft over
the waters N of Cabo San Lazaro while merging SW and NW swell is
supporting 7 to 9 ft seas across the offshore waters from Cabo
San Lazaro to Cabo San Lucas. Inside the Gulf of California,
light and variable winds are over the central portion while light
to gentle NW winds are over the southern portion and gentle S to
SW winds are over the northern portion. Seas are 3 ft or less
over the Gulf, except for higher seas of 3 to 5 ft in SE to S
swell over the southern portion. Seas of 6 to 8 ft in SW swell
are at the entrance to the Gulf. Light to gentle winds prevail
elsewhere along with 6 to 8 ft seas in SW swell, including the
Gulf of Tehuantepec.
For the forecast, high pressure will remain centered N of the
region through the week, maintaining moderate to locally fresh NW
winds across Baja California offshore waters. Rough seas for
these waters will subside Mon as NW swell decays. Elsewhere,
mainly tranquil marine conditions will prevail.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Mainly light and variable winds prevail across the Central
American offshore waters along with moderate seas to 7 ft in SW
swell. South of the monsoon trough, and between the Galapagos
Islands and Ecuador winds are gentle, south to southeast in
direction, and seas are 6 to 8 ft in long-period SW swell as
noted in the most recent altimeter satellite data passes over
these waters.
For the forecast, a weak pressure pattern will result in light
to gentle
