Areas and period:
This alert is valid until Thursday evening and then alert 18.2 should appear, as it should continue to snow continuously in the south. Only where is not quite clear yet.
The area until Thursday evening goes from the Grand Paradiso massif to the Upper Engadine / Adamello and the core is, as so often, in the Monte Rosa / Simplon / Ticino triangle.
Snow line:
The snow line is likely to be around 1300m in the core with heavy precipitation in some valleys and around 1900m in the peripheral areas with light precipitation on Wednesday.
Fluffy powder with a guarantee will probably only be available above 1800-2000m, as the zero degree line is likely to be around there.
Wind:
Surprisingly tame for the amounts! Even at 3000m there are hardly any strong winds or storms and the wind-protected areas should remain quite fluffy, even at the top. Since the base and the old snow problem in parts of the south (e.g. in Ticino) isn't that scary or hardly exists at all, that's good news for the days to come.
