Apparently it messed up their TV. Forget the actual threat of a Tsunami, fans were up in arms with the obstructing weather warnings. Of course, the Tsunami happened to coincide with the very special episode of FMA: Brotherhood where Winry strips in front of Edward. Wait, what? I don't remember that episode, but I'm sure it needed the tag "Very special episode," since I'm sure we would have all learned an important lesson of some sort. AND IT WAS RUINED!
Sankaku reports that the weather warnings were varied by locations, but hey, I like to pretend this episode was really just an action packed weather commentary.
