Endless snow ... and nowhere to go because of it

I honestly don't know the English word for it, but because of the snow, we are stuck at home ... We can't go visit my mother as we had planned and our spirits are a little bit low at the moment because of it. On the bright sight, my mother is finally doing better, walking longer distances (with help) and generally is better oriented than she was about a week ago. I called her physiotherapist today and she said that perhaps, if everything went well, my mom could go home sometime around next weekend. That's perhaps an optimistic view of things, but one can always hope.
