It's like that white powdery stuff you guys have, but ours falls from the sky instead of being smuggled in by rickety boats. And if you snort ours, it just gives you brain freeze 🤪
If you put dielectric grease on your connections at the receiver, it will help. We don't normally run in snow, but I have done it. I fried a servo on my Dromida buggy running in 1/2" of snow one time. It is fun though if you have the right snow and are a bit waterproof.
