Off Piste Snow & Weather: 21 - 27 Dec Savoie / N. French Alps

Off Piste Snow Depths – Haute Tarentaise – Meteo France

Off-piste snow depths are exceptionally good for the time of season. We’ve been experiencing some beautiful cold powder snow conditions, particularly on N facing slopes at high altitudes.

With the milder temperatures and sunshine predicted in the week ahead, this will become heavier and tricker to ski. There should still be some great snow on shaded high N facing slopes though. Wind will play a factor, as always, causing exposed surface snow to become hardened and crusted. On sunny S facing slopes below 2000 m, the snow will become quite crusted at the surface.

 

Areas of windslab have been formed by the recent high NE winds. Be especially wary of NW to W to SW facing slopes above 2800 m, that have been very wind-affected. Also beware of areas near ridges, and the windy French/Italian border.

The deeply-buried weak layer of depth hoar (‘sugar snow)’ persists, particularly on high cold N facing slopes. These have been less affected by the stabilising effect of recent warmer temperatures.

We’ve been seeing surprisingly little recent avalanche activity recently, despite Meteo France’s predictions of an avalanche rating 3 or even 4. (See the daily avalanche bulletins on www.meteofrance.com/previsions-meteo-montagne/bulletin-avalanches). Indeed, nothing happens most of the time. But it’s important not to take that as a green light for ‘no danger’. Many people have been skiing very steep high slopes, and ‘getting away with it’. ‘Nothing happens’ doesn’t mean the decision to ski that  slope was a sound one, though.

It’s extremely tempting, and only natural, to see other people’s ski tracks as a reassuring sign. It would be easy to deduct that someone has skied down a slope before, so all will be well.

See Henry’s ‘Facebook Live’ report earlier this week. Henry was having an awesome off-piste morning, in a danger rating of 3. He realised how easy it would be to let down your guard and to stop applying risk assessment and basic risk reduction measures, because there was little evidence of avalanche activity and nothing bad was happening.

There’s a very enlightening account (in French) of an avalanche accident in Courmayeur, Italy, earlier this week. Here, an avalanche was distance triggered from 200 m above, on an off-piste slope. The slope had at least 30 tracks on it. Ski schools were there. Everything seemed pretty stable. The victim was applying good off-piste etiquette. He triggered his airbag but it became punctured on some bushes. His very brave account can be found in French on www.data-avalanche.org,

Tip of the week

Keep it safe and keep applying risk assessment and reduction methods. You can greatly reduce the chances of having an accident (and have more fun) off-piste with our simple downloadable Off-Piste checklist.

See our basic framework of risk assessment and reduction methods in our previous blog: www.henrysavalanchetalk.com/off-piste-quick-reference.

Even if you don’t apply all the methods perfectly, you’re going to be way safer than if you don’t apply them at all!
