In addition to the incident in Chandolin, reported by Ise, Pistehors are reporting the death of a mountain guide in the Pyrenees yesterday.

On Snowheads, steilhang notes 3 fatalities from four avalanches...
Three deaths in Austria today in separate incidents. One in Damüls, one in Kleinwalsertal and one which happened yetsreday in Tirol. In the incident in Tirol the rescue teams were only able to get to the victim today!

In the incident in Damüls a 22 year old snowboarder skied into a slope that was closed for avalanche danger. His group had already skied the slope twice, but on the third run the slab released and buried one of them. None of them was wearing a transceiver!

In the incident in Kleinwalsertal a 41 year old skier skied into a popular powder run and released a slab. The avalanche situation was so extreme that the rescue services had to dynamite the slope before attempting to search for the victim! He was found after having been buried for three hours.

Lech had a lucky escape when an avalanche went down over the piste in the Mohnenfluh area, covering the piste over a length of 120 meters. Pure luck that nobody was buried!


Be careful out there! Warm temperatures over the next few days may well increase instability off piste, so take note of local warnings and don't ski closed slopes - they're closed for good reason.

What do you mean by "warm" temps?

Above freezing... ...quite a few areas (mostly West and South Alps) are having a mild couple of days before Xmas (when it gets cold).

Conditions are actually stabilising, the temperature spike isn't helpful but generally risk is a lot lower than a few weeks ago. It's probably a problem with the influx of holidaymakers without sufficient skills, not properly equipped for the slopes they're attempting and ill-informed about the risk.

I was under the impression warmer temps increased stability, allowing the layers to "fuse".. or at least speed up the process.

Yes, that's correct. In this instance, add in, very low temps for a few weeks before, a very dry snowpack which has not bonded, and a swift rise in temperatures (the spike) and the result is plenty of instability. Normally, a gentle rise in temps, cause a bit of percolation in the layers, and they then "fuse" (I think). )

that's true, it depends on the layers already present though, generally it (positive temperatures) will stabilise powder snow but destabilise already saturated layers.
