Central Pacific Hurricane Center forecasters are keeping an eye on a tropical wave that is producing disorganized showers and thunderstorms some 1,700 miles east-southeast of the Big Island.
Some gradual development of the system is possible during the next 48 hours as it moves westward into the Central North Pacific Basin, forecasters said Tuesday night. They gave the system a 10 percent chance of forming into a tropical cyclone during the next two days.
Elsewhere, in the basin no tropical cyclones are expected through Thursday evening.
National Hurricane Center forecasters in Miami are also keeping tabs on the system as it moves toward the Central North Pacific Basin, which is located between 140 degrees west longitude and the International Dateline.
Central Pacific Hurricane Center officials predicted four to seven tropical cyclones this year in the Central North Pacific Basin. Overall, they give this season an 80 percent chance for a normal to above average number of tropical storms to form.
The Central Pacific hurricane season began June 1 and ends Nov. 30.
