Hurricane Effect (2)

Hey everyone,
I need to create a hurricane effect from an aerial view, and be able to zoom in on it. As afr as the shader goes I have all that worked out, I am running into problems creating the movement and overall look of the hurricane. I also thought that fluids may be something I should look into that's why I am posting here. I guess I was just hoping someone on here had done this before and could provide some good insight for me? Any help would be fantastic thanks!
