and then turn northward by the weekend.

* Formation chance through 5 days...high...80 percent

2. Showers and thunderstorms associated with a weak area of low
pressure located about 1325 miles  east-southeast of the Big Island

Any additional development of this system is expected to be slow to
occur while it moves slowly westward during the next few days.
