Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Sun Aug 18 2024

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.
