Tropical Weather Outlook
NWS Central Pacific Hurricane Center Honolulu HI
200 AM HST Sun Aug 18 2024

For the central North Pacific...between 140W and 180W:

1. Approximately 1700 miles east-southeast of Hilo, Hawaii:
Disorganized showers and thunderstorms are associated 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 several 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 westward to west-northwestward over the
western portion of the East Pacific basin before it possibly merges
with the disturbance currently located further west.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...50 percent.


2. Approximately 1300 miles southeast of Hilo, Hawaii:
Another area of low pressure located well southeast of the Hawaiian
Islands is currently associated with 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
this 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.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...40 percent.



Elsewhere, no tropical cyclones are expected during the next 7 days.
