Replying to Atomos Ninja V + rain and snow

Hey everyone, I just picked up an Atomos Ninja V Kit for my GH5. Im curious if anyone on here has any experience using this in the snow/rain. Aside from using the hood, has anyone on here had any issues/remedies with water getting into the atomos? The main part I am concerned about is the fan vent at the top.

I work primarily in the mountain bike industry, but I have a couple projects this winter i'll be shooting here at Baker where it rains a lot and the snow is super wet. My GH5 is weather sealed so thats never been an issue.
