Time period
Until Saturday morning. The refresh comes just in time for all weekend warriors. In the Maritime Alps possibly until the evening.
Areas
From France to Tyrol, but it will be tight with the alarm, so don't be surprised if it hardly gets 30cm even in the alarm area. The core will probably lie between Lower Valais and Glarus in the foothills of the Alps in northern Switzerland, where 20-30cm have already fallen today. In the south, it will probably only be interesting towards the Maritime Alps and Piedmont.
Snowfall limit
Far below. Ergo: Only "the good stuff" is coming.
Wind
Hardly worth mentioning, so powder right up to the top. The problem, however, is that it hardly pushes into the Alps, so that the full amounts can only be reached in the foothills of the Alps and in the northern congestion.
