@YW mod 105-
I actually was just looking up this issue this past shabbos.
If the snow fell on shabbos, It is muktzah according to most poskim because of nolad.
If before shabbos 1) you should’ve shoveled before shabbos
2) There is still a problem of muktza, R’ Bodner’s muktza book brings down R’ Moshe who says that it is muktza no matter what.
Addtionally there is a problem of boneh and obviously carrying if there is no eruv
@zahavasdad-
There are always going to be some people who don’t shovel. Frum or not. So if the snow is so bad for you that it is a sakana, don’t go to shul!
