Depending on the area and altitude, there are already some melting crusts within the snow cover that have been created by rain events or warm air intrusions. Weak layers often develop around these. Why is this?

The fog hangs in the valley, the days are getting shorter, the nights cooler, the drinks warmer. Industry magazines report either enthusiastically or critically on the events that take place on every glacier every weekend. It's the most beautiful time of the year. It's fall. But especially for skiers who are more (i.e. exclusively) off-piste, the time before the real start of winter and the first heavy snowfalls harbors a considerable number of dangers that should be taken into account.

"On Sunday (refers to the week before last [5.1.14]) it snowed wet in the south, in some places up to over 2000 m, and after a starry night, dry powder was also to be found much lower down on Monday. (...) I've been thinking about a build-up transformation of the wet fresh snow. Is that conceivable?"
