There has already been up to 25 cm of fresh snow, which is lying more or less on top of our November snow.
The initial situation:
It looks like the beginning of October, only the build-up is much worse than in October, because in the last few weeks the weather has turned our remaining snow on the north-facing slopes into a nursery full of marbles and the inclined freeskier now wants to run full throttle into the room, hungry for powder (to get away from the ball-bearing metaphor). You can fall flat on your face or, in our case, easily trigger a snow slab. The LLBs in the west see it similarly with level 4.
So before I write anything about the quantities: Read the LLBs even if there is still hardly any snow and only stay where there was no snow before as long as this foundation is not thickly covered or you know the snow cover from before very well.
But it will finally snow more than 30cm for the last FIVE weeks and the question is:
Where?
And as so often in recent years, the answer is: in the west. From the Hautes Alpes to the Lower Valais will probably see the most snow by Tuesday afternoon. A little could also fall from the Bernese Oberland to the Arlberg. Otherwise, it looks rather bleak.
The snow line should hover around 1000m, so you can definitely tackle trees in France and parts of Switzerland with some base from yesterday. Nevertheless, the surface will be scratchy.
As the current is quite strong, everything above the tree line will be pretty blown away anyway. At least the wind will ensure that the whole thing is pushed quite far towards the main Alpine ridge and into Valais.
