You rarely hear me say that it's somehow too much, but if the oracle is hiding behind the main Alpine ridge and the SLF considers danger level 5 possible for Monday, then it's probably a bit too much. We are already close to setting all-time snow depth records and it's possible that records from 1999 will be pulverized on Monday. And not at the end of February or beginning of March, when there is usually the most snow, but at the end of January.
Alert period and areas
The entire northern Alpine ridge from France to the Rax. It will probably only be apocalyptic (the core) from the Arlberg to the Hautes Alpes. The alert is valid until Monday evening.
Snowfall limit
Ullr sticks to our motto 17/18 and rides a rollercoaster. Until Sunday in the powder area from Monday in the west rain up to above the tree line...
At the moment, the snow line is dropping everywhere. Tomorrow it will rise to 1200-1300m in the west of Switzerland and France, in the east and inner Alps it will remain lower.
Then it will drop again everywhere and rise again to 1500m in the west on Sunday afternoon. Monday it will rain there up to 2000m. In the south, east and inner alpine in eastern Switzerland there may still be snow from 1400-1700m.
Saturday and Sunday, the snow line will generally be around 200m lower in the east than in the west.
