Iona strengthened to a Category 3 hurricane several hundred miles south-southeast of Hawaii, but poses no threat to the islands, the U.S. National Hurricane Center said Tuesday.

Tropical Storm Keli, meanwhile, was located about 795 miles southeast of Honolulu with maximum sustained winds near 40 mph and higher gusts. Keli was moving west at 15 mph and is expected to maintain that general motion over the next couple of days.
