Tropical Storm Julio could hit Big Island this weekend


Tropical Storm Julio continues to pack 60 mph winds as it moves west across the Eastern Pacific, National Hurricane Center forecasters based in Miami say.

Julio, which is located 1,145 miles southwest of the southern tip of the Baja California peninsula, is packing maximum sustained winds around 60 mph and moving west at 13 mph, according to forecasters. The storm is expected to continue moving west-northwest during the next couple of days. Julio is expected to become a hurricane on Wednesday.

Tropical storm force winds currently extend outward up to 105 miles, according to forecasters.

Forecasters said that the storm could begin affecting the Big Island on Saturday or Sunday.

Forecasters are also keeping an eye on a weak area of low pressure located several hundred miles south-southwest of the Acapulco, Mexico, that is producing disorganized showers and thunderstorms. Upper-level winds are expected to become more conducive for development of the storm over the next few days.

Forecasters gave the storm a 30 percent chance of forming into a tropical cyclone within 48 hours and a 30 percent chance of forming into a tropical cyclone within five days.
