The National Hurricane Center continues to track a disturbance in the Eastern Pacific. Forecasters said Monday night that the system is located about 1,350 miles east-southeast of the Big Island.
Environmental conditions are expected to be conducive for development. A tropical cyclone will likely form in the next few days while the system moves west-northwest at 15 to 20 miles per hour.
The National Hurricane Center said there’s a 70 percent chance that a tropical cyclone could form in the next 48 hours, but there’s a 90 percent chance that it could develop into a tropical cyclone in the next five days.
