In sintesi

Weak basal facets underlie a variety of untrustworthy windslabs and crusts. Many exposed areas are blown out and rocky.

    Natural avalanche activity has subsided but snowpack tests show that the weak facets at the basal level continue to be the big issue. The slab that rests on this weak structure may indicate some strength in places but in fact very little has changed.

Weather Forecast

Light snow and continued moderate temps are forecast. This is unlikely to change the danger rating in the short term.

Snowpack Summary

Wind slabs and facets dominate the Alpine snowpack. Treeline presents a variety of crusts, slabs and thin areas overlying large weak facets. Below treeline a rain crust is present and the snowpack is solidly frozen in most areas. Thin windslab is developing in steep lee areas.

Avalanche Summary

No new avalanche activity was noted today.
