What the hell are you talking about March is one of the best months in the alps for snow. I made 5 exits in March last season and it went like this:
1st week: several days of snow storm, powder everywhere, stuck to treeruns, and then a sunny day
2nd week: snow storm in Avoriaz (France) with fresh powder even under 1000m, then sunny
3rd week: sunny and no fresh snow at Silvretta Nova (Austria)
4th week: Orage Freeski Open in Laax (Switzerland), a bit slushy
5th week: 50 cm of freshies overnight in Laax (Switzerland), sunny, some sick lines!!
Val Thorens is a terrible reference for powder.
