Hurricane Iona, the first named storm of the Central Pacific season, quickly intensified overnight into a Category 1 hurricane far southeast of the Hawaiian Islands, while a new tropical depression also formed in the basin.

Hurricane Iona was expected to move westward for the next couple of days and stay far south of the Hawaiian Islands, forecasters said.

The National Hurricane Center said Monday, July 28, it is keeping tabs on four systems in the Pacific Ocean, including Tropical Storm Iona.
