200 PM HST Sun Aug 18 2024

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

1. Approximately 1300 miles southeast of Hilo, Hawaii (EP90):
A low pressure system located well southeast of the Hawaiian
Islands is producing disorganized showers and thunderstorms. This
disturbance is forecast to interact with the disturbance located to
its east-northeast (mentioned below). If this system becomes the
dominant disturbance, some gradual development is possible, and a
tropical depression could form in the next couple of days as it
moves slowly west. If a depression does form, a
faster west-northwestward motion into the Central Pacific basin is
likely during the latter half of the week.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...60 percent.


2. Approximately 1800 miles southeast of Hilo, Hawaii:
Disorganized showers and thunderstorms continue in association with
a broad trough of low pressure located well southwest of the
southern tip of the Baja California peninsula. This system is
forecast to interact with another disturbance to its west-southwest
(EP90 mentioned above) over the next few days which could limit
additional development. A tropical depression could still form
during the middle part of the week while the system moves generally
west-northwestward before possibly merging with the disturbance
(EP90) currently located further 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.
