Upper Susa and Chisone Valleys

The new snow and wind slabs of last week are to be evaluated with care and prudence above the tree line.

The new snow and wind slabs of last week are to be evaluated with care and prudence above the tree line.

The wind slabs are to be found in particular above approximately 2300 m. Dry avalanches can over a wide area be released by a single winter sport participant and reach large size in isolated cases. This applies especially on very steep slopes adjacent to ridgelines and in gullies and bowls. As a consequence of warming during the day and the solar radiation, the likelihood of moist avalanches being released will increase a little in particular on rocky slopes at low and intermediate altitudes.

Over a wide area 40 to 80 cm of snow, and even more in some localities, fell in the last seven days. The fresh snow of the last few days as well as the wind slabs formed during the snowfall are poorly bonded with the old snowpack.

The weather conditions will foster a gradual strengthening of the snowpack.
