Central Pacific Tropical Weather Outlook
For the central north Pacific, between 140°W and 180.
1. An area of showers and isolated thunderstorms associated with a weak low pressure system is located about 750 miles southeast of Hilo, Hawaii. Environmental conditions appear more favorable for gradual development with this still disorganized system as it moves west at 10 to 15 mph over the next day or two. There is a medium chance, 30 percent, of this feature becoming a tropical cyclone during the next 48 hours.
Elsewhere, no tropical cyclones are expected through late Friday night.
