Alert period and areas
The alert goes from the Hautes Alpes to the Dachstein, but east of the Arlberg it will be tight with the amounts. The core goes from the Lower Valais to the Hautes Alpes and as these areas have a bit of a base from the last westerly traffic jam, you can probably even go skiing there over Christmas. The alert goes from Sunday 22/12 to 25/12 as it doesn't really stop snowing.
Wind
Storm, as always with a strong westerly flow. There is almost never much snow and little wind, except in rare counter-currents. However, it pushes a lot towards the main French ridge in the direction of Italy and Valais. The areas further north-east hardly have any real congestion.
