One person died and four others were injured after a "rogue wave" hit the Viking Polaris cruise ship while it was sailing toward Ushuaia, Argentina, on Tuesday night, officials said. “It is with great sadness that we confirmed a guest passed away following the incident,” Viking said in a statement Thursday. Rogue waves, or extreme storm waves, are uncommon, unpredictable and "greater than twice the size of surrounding waves," according to the National Ocean Service. “Everything was fine until the rogue wave hit, and it was just sudden. The Viking Polaris’ next departure, the Antarctic Explorer cruise scheduled for Dec. 5-17, was canceled due to the incident.
