As Iselle fizzles into a post-tropical storm, all eyes now turn to Hurricane Julio.
The Central Pacific Hurricane Center says Julio is about 500 miles east of Hilo, as of 5 a.m. Saturday.
The storm is moving west-northwest near 16 mph. This general motion is expected to continue through Sunday.
Maximum sustained winds are near 100 mph with higher gusts, which makes it a Category 2 hurricane. Gradual weakening is forecast during the next couple of days, but Julio is forecast to remain a hurricane through Sunday night.
Hurricane force winds extend outward up to 35 miles from the center and tropical storm force winds extend outward up to 165 miles.
Large swells generated by Hurricane Julio are expected to produce building surf along most north and east facing shores of the main Hawaiian islands starting Saturday night and continuing into early next week.
