Now, Gandalf isn't always right, so Aiwendil, I would love to see where you found how Saruman stirred the storms, because I could be missing something.

As Encaitare said, I was referring to the change Peter Jackson made. Sorry if I didn't make that clear.

Tuor identified some reasons to think that the snow storm was not caused by Sauron; I agree with these. Of course, it's never made entirely clear. And that contributes somewhat to the realism.
