The Pacific Ocean is teaming with tropical activity as forecasters track two named systems and a few other disturbances this week.

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.

“Confidence remains high that Iona will stay well south of the Hawaiian Islands,” forecasters report. Hurricane-force winds extend outward up to 15 miles from the center, while tropical-storm-force winds extend outward up to 70 miles from the center. There are no other coastal watches or warnings in effect.
