Well truly bombproof tents like the full weight biblers (bibler bombshelter, eldorado, etc. come close - you do still have to keep them dug out to some extent of course. You'll have a lot easier time with something like that than you will something like a shangri la in that kind of weather. Of course the tent is a heck of a lot heavier but hey - that's winter camping!

Would I carry such a thing the rest of the year or somewhere I don't expect to need it? heck no.
