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

1. The area of showers and thunderstorms centered about 500 miles south southeast of Hilo, Hawaii continues to show signs of improved organization. However, the coverage and intensity of the thunderstorms within this area has been fluctuating during the past 12 hours. Gradual development of this feature is possible as it continues moving slowly toward the west northwest at about 10 mph during the next couple of days. There is a high chance, 60 percent, of this system becoming a tropical cyclone during the next 48 hours.

Elsewhere, no tropical cyclones are expected through Thursday evening.
