For the central north Pacific, between 140°W and 180.

1. An area of low pressure associated with post-tropical cyclone Eight-E is located about 680 miles east of Hilo, Hawaii. The low is generating disorganized showers and thunderstorms as it moves west at 10 to 15 mph. Redevelopment of Eight-E is not expected due to unfavorable upper-level winds over the next couple of days.

* Formation chance through 48 hours, low, near 0 percent.

2. A broad area of low pressure located about 600 miles south-southwest of Hilo, Hawaii continues to generate showers and thunderstorms. Although some slow development cannot be ruled out, upper-level winds and plenty of mid-level dry air north of this feature will likely inhibit further development over the next couple of days as it moves west at 10 to 15 mph.

* Formation chance through 48 hours, low, 10 percent.

3. The National Hurricane Center is issuing advisories on hurricane Guillermo, located about 1600 miles east-southeast of Hilo Hawaii, under AWIPS header tcpep4 and WMO header wtpz34 KNHC. Guillermo is expected to cross into the Central Pacific Hurricane Center area of responsibility on Saturday.

Elsewhere, no tropical cyclones are expected through late Saturday night.
