10-40 cm the last 36 hours. The next 36 hours another 20-60 cm of freshies. We end 2012 with a bang!
Last weekend was pretty warm, but that was good news. A lot of weak layers in the snowpack are gone, though you can still find some on north faces above 2400 meters. Always read the latest avalanche bulletin and adapt your riding on that! You don't really have to go that high with the snow that's coming. The northwest of the Alps (Isère, Savoie, Haute-Savoie, Wallis, the north side of the Alps, Vorarlberg) all have a very thick snowcover and another 60 cm of snow will be added the next 36 hours.
A new storm is arriving in the night of Wednesday to Thursday and you can ride powder on Thursday afternoon in the forests of the French Alps. It's getting deep on Friday morning. Go for the little areas and family resorts. Less powder stress and less people.
It will still be snowing in the northern Alps on Friday morning, but the sun will come out during the day. It will be warm and sunny everywhere on Saturday. There won't be a föhnwind and the snow will remain fresh till the end of the year on north faces, in the forests and inneralpine valleys. You don't have to expect any significant snowfall till the end of the year.
A big slide? It looks like 2013 will start with a north stau. This is still pretty far way, so until then:
Thursday afternoon: powder in the French northern Alps and the west of Switzerland
Friday: powder in the Isère, Savoie, Haute-Savoie, Wallis, the north side of the Alps, Vorarlberg
Saturday & Sunday: north faces,the forests and inneralpine valleys
