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.

Two tracker maps from the National Hurricane Center (NHC) and Central Pacific Hurricane Center show how the paths of Hurricane Ione and Tropical Storm Keli are forming. Hurricane Iona formed on Monday after undergoing rapid intensification. Shortly after Iona formed, Tropical Storm Keli also developed.
