For the eastern North Pacific...east of 140 degrees west longitude:

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Seven-E, located well south of the southern tip
of the Baja California peninsula.

1. Well Southeast of the Hawaiian Islands:
Another area of low pressure located well southeast of the Hawaiian
Islands is producing some disorganized showers and thunderstorms on
its western side. This disturbance is forecast to interact with the
disturbance located to its east. If this system becomes the dominant
disturbance, some gradual development is possible, and a tropical
depression could form by the middle part of the week while it
initially moves slowly over the western portion of the East Pacific.
A faster west-northwestward motion into the Central Pacific basin is
likely by the latter portion of the week. Information on this
system's development can also be found in the Tropical Weather
Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...50 percent.

2. Western Portion of the East Pacific:
Disorganized showers and thunderstorms continue in association with
a broad trough of low pressure located well west-southwest of the
southern tip of the Baja California peninsula. This system is
forecast to interact with another disturbance to its west-southwest
over the next few days, which could limit additional development if
this system does not become the dominant disturbance. Regardless, a
tropical depression could still form during the middle part of the
week while the system moves generally west-northwestward before it
possibly merges with the disturbance currently located further west.
Information on this system's development can also be found in the
Tropical Weather Outlook for the Central Pacific basin.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...40 percent.

3. Eastern and Central Portion of the East Pacific:
Yet another area of low pressure could form well to the south of the
southwestern coast of Mexico around the middle of the week.
Environmental conditions appear generally conducive for some slow
development of this system thereafter as it moves slowly
west-northwestward into the central portion of the East Pacific
basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.
