It’s been another week of great off-piste conditions in the N French Alps. Lucky areas near the French/Italian border received up to 60 cm fresh snow between last Sunday night and Tuesday. These areas stretched from Le Fornet, Val d’Isère in the north, through Bonneval and all the way down into the S French Alps (Montgenèvre and Isola 2000).
The week ahead looks like being mainly dry and sunny in the mountains, with temperatures normal for the time of season.

With little fresh snow expected, and slopes easily accessible from the lifts now tracked out, it will be ‘walkies time’ this week, with touring skis and skins being helpful to find the best off-piste snow.
Current danger rating in the Tarentaise
The avalanche danger rating across virtually all the French Alps is currently a ‘moderate’ 2 out of 5, with the colder north’ish facing slopes most at risk. Things have become a lot more stable with the recent cold, dry conditions (albeit with some temporary instability in areas along the French Italian border, which received fresh snowfall at the beginning of last week). See below for more on this.
Yes, the off-piste snowpack is currently a lot more stable. However, following a succession of cold days and bitterly cold clear nights, there’s now another persistent weak layer ‘lurking’, particularly on high north’ish facing slopes. ‘Sugary’ incohesive snow is starting to reappear deep into the snowpack and even poking into the snow surface. This will only really become a problem when a significant amount of fresh snow falls on the top of it, and will then become something we need to watch out for. We’ll return to this subject next week.
In those areas near the French/Italian border, which received significant amounts of fresh snow last week, quite a lot of skier-triggered avalanche activity took place. Here, for a couple of days, the avalanche risk level rose to a 3 or 4 out of 5 with the fresh snowfall. Predictably, as visibility improved, a ‘powder frenzy’ ensued, with some really irresponsible behaviour from skiers heading out to get the best snow with no regard for others.
In the Grand Vallon area above Le Fornet, Val d’Isère, uphill skiers accidentally triggered an avalanche on top of others on slopes below, in their hurry to reach the best powder. Fortunately, everyone survived with only minor injuries. Many other avalanches triggered by skiers have been taking place too, particularly in those areas which received the bonus snowfall along the French border with Italy.
As I mention in my talks, with the growing popularity in off-piste skiing and ski touring, triggering avalanches on top of others is occurring more and more frequently. There’s no excuse for this type of behaviour. Not only is it incredibly selfish, but it endangers other people’s lives, and can even result in a jail sentence if someone is hurt or killed.
