The Miami-based NHC in its latest advisory says Iona was about 790 miles off Honolulu, with maximum sustained winds near 115 mph.

A major hurricane was churning across the Pacific Ocean but was several hundred miles south-southeast of Hawaii and posed no threat to the islands, forecasters said Tuesday. Hurricane Iona is one of two major weather systems in the central Pacific Ocean.

Hurricane Iona was expected to move westward and does not pose any land threat to the Hawaiian Islands, forecasters said.
