why don't we say pouring snow?

At the men's Olympic giant slalom hill (which is on live now) there is a lot of snow falling. I'm not listening to the commentators, so I don't know if this is perceived as adding difficulty. Surely people who are at that level train most days, which would include snowy days. I know that precipitation looks more intense through the camera lens, but my first thought was "look at the snow pouring down." I don't think that is what we say.
