It's snowing in Trinities, Mt. Shasta and Sierras and further north

I was watching the weather radar for California and it is presently raining as far south as Big Sur and as far north as Roseburg, Oregon. And it is snowing in the Trinity Mountains and on Mt. Shasta and in the Sierras which hopefully will be a good thing and I hope not too many backpackers, campers and 4 wheel drivers etc. aren't snowed in at this point or will be soon that didn't watch the weather reports, (unless they are prepared and want to be snowed in in a cabin somewhere).
