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

Hurricane Iona rapidly strengthened overnight into a Category 3 hurricane well south of the Hawaiian Islands and is expected to reach Category 4 intensity later today, forecasters said.

Andrew Austin-Adler, a student meteorologist specializing in tropical cyclones, said on X: "Strongest CPAC hurricane since WALAKA is inbound. Iona is on the fast track to reaching major hurricane strength - official forecast is 120mph which could be conservative."
