Take cover, Hawaii Five-O fans. A tsunami is coming.

On next week's episode of the CBS hit (titled "Kaie'e"), the man in charge of the Tsunami Warning Center goes missing, which poses an especially immediate threat because a storm is headed for the island.

The installment, previewed here, will feature a pair of guest stars: singer JoJo and character actor Joel David Moore, likely best known for his recurring role on Bones.
