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.
...SPECIAL FEATURES...
Broad low pressure of 1008 mb, centered along the monsoon trough
near 09N125W, well SW of the southern tip of Baja California, is
producing numerous disorganized moderate convection from 08N to
12N between 120W and 130W. Environmental conditions appear
conductive for development, and a tropical depression is expected
to from during the middle part of the week while moving westward
or west-northwestward at around 10 kt across the western portion
of the East Pacific. This low has a medium chance of tropical
cyclone formation within the next 48 hours and a high chance over
the next 7 days.

wwww.hurricanes.gov for more details.
...TROPICAL WAVES...
The southern portion of a tropical wave has an axis along 82W, N
of 05N, moving W at around 10 kt. Scattered moderate convection
has develop N of 05N and E of 87W in association with this wave,
impacting waters near Panama.
A tropical wave has its axis along 108W from 05N to 15N, moving W
at around 5 kt. Scattered moderate to isolated strong convection
is noted from 05N to 12N between 103W and 110W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough axis extends from 09N81W to 1008 mb low
pressure near 10N110W to 1008 mb low pressure near 09N125W to
06N140W. Aside from convection near the trough already depicted
in the Special Features and Tropical Waves section above,
numerous moderate convection is noted within 180 nm S of the
trough between 130W and 133W and from 05N to 08N between
111W-114W. Scattered moderate convection is within 60 nm N of
the trough between 109W-114W.
...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 NW to N winds across the Baja California offshore
waters. NW swell is producing seas to 9 ft over the waters N of
Cabo San Lazaro. Inside the Gulf of California, light winds and
slight seas prevail, except for 3 to 6 ft seas in SW swell near
the entrance. For the remainder of the offshore waters, light to
gentle winds dominate along with 6 to 8 ft seas primarily in
long- period S to 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. NW swell will propagate
through the offshore waters of Baja California Norte through Fri
night, bringing rough seas. Elsewhere, mostly tranquil marine
conditions will prevail through the period.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Mainly light and variable winds are over the Central American
offshore waters under a weak pressure pattern
