Yes, but only from 1400m, and a thin layer, not 50 cm! In Crans-Montana, there is again 20 cm (1m60 in february...), you can go skiing without problem!
In Switzerland too ( In my village, it's raining, I hope it's snowing in Crans-Montana... I want to go to Crans-Montana tomorrow, if it rain, I think I will stay at home! They predict snow from 1500-1700m (Crans-Montana is 1500m)
