800 PM HST Sun Aug 18 2024

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

1. Approximately 1300 miles southeast of Hilo, Hawaii (EP90):
Showers and thunderstorms are showing some signs of organization in
association with a low pressure system located well southeast
of the Hawaiian Islands. This disturbance is forecast to interact
with a disturbance located to its east-northeast. If this system
becomes the dominant disturbance, some gradual development is
possible, and a tropical depression could form in the next couple
of days 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...medium...50 percent.
* Formation chance through 7 days...high...70 percent.


2. Approximately 1700 miles southeast of Hilo, Hawaii:
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.
Regardless, a tropical depression could form during the middle part
of the week while the system moves slowly west-northwestward before
it possibly merges with the disturbance currently located farther
west.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...40 percent.



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