Lo esencial

Wind slabs in the alpine and treeline are the primary concern. Expect the temperature to fall as cold air invades from the north.

    Recent new snow fell with moderate southwest wind, which has promoted wind slab development in lee terrain.

    Around 50-80 cm of snow sits above a weak layer of surface hoar. This layer is most likely found in shaded and sheltered areas between 1700 m and 2000 m.

Confidence

Moderate - Due to the number of field observations

Snowpack Summary

15-30 cm of new snow with moderate southwesterly winds is sitting on a crust on all but northerly aspects, wind-affected surfaces in the alpine, and possibly a mixture of weak feathery surface hoar and/or sugary facets in sheltered terrain at treeline and below.A crust that recently formed right to mountain top on southerly aspects and on all aspects below 1700 m is now buried 50-80 cm deep. Additionally at this depth, feathery surface hoar may be found in shady sheltered areas at treeline. The remainder of the snowpack is generally well-settled and strong.
