Highlights

Strong southwesterly winds combined with new snow on Friday night will contribute to wind slab development.Good skiing can still be found in sheltered areas below tree line.

Avalanche problems

  • Wind Slabs

    Recent snow is available for transport. Wind slabs are likely in lee slopes in lee slopes.

    Persistent slabs sit over different weak layers depending on elevation & aspect. Above 1950m a buried facet layer down 20-40cm is the primary concern. Below 1950m, a faceting crust down 40-70 is presenting a more stubborn version of a similar problem
