While emergency sirens warned of an impeding tsunami Tuesday, Hurricane Iona slipped by the south of the Hawaiian Islands, continuing on a 20-mph westward track away from the islands. Meanwhile, Tropical Storm Keli was almost directly south of Hawaiʻi Island as of 5 a.m. this morning, also moving west but at 21 mph.

Tropical Storm Iona, formerly Tropical Depression One-C, has become the first named storm of the season in the Central Pacific. Just before 5 p.m., Iona was located about 960 miles southeast of Honolulu, packing maximum sustained winds of 40 mph.

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