Club Penguin rain storm

My decision is final. The reason for the thunder storm is because that the new water card Jitsu is coming out. I have proof from two websites. I found one called Just Club Penguin. It had pictures of water card jitsu decks and all! If you want the other website I found proof from then there is a link. I think you can find it in this post!
(If you really can't work it out, even though it is in purple, the word is water and it is right infront of you.)
