Yet another round of snow will keep wintry conditions for Friday.
Be alert to conditions that change with elevation and sun exposure in the afternoon.
Increasing winds and unconsolidated snow will likely develop reactive wind slabs in the immediate lee of alpine features and on cross-loaded areas. As recent wind has varied in direction, watch for wind slabs on all aspects. Be careful on steep, unsupported and/or convex terrain features, where wind slabs are more likely to get triggered.
No new avalanche observations were reported or observed in the last 24 hours

As of Thursday afternoon, light snow is being added to the recent snow (10-15 cm) received at higher elevations since the last weekend. In the alpine and treeline, these accumulations bond well to a solid underlying crust. Winds, light until now, have already picked up and will redistribute the fresh snow onto lee slopes. Below treeline, the mild temperature of the last past days is favouring the rapid settlement of the recent snow. A melt-freeze crust overlies 20 cm of denser snow. This crust is slightly less noticeable in northern aspects. The mid-snowpack is well consolidated, and of increasing density, interspersed with several crusts of refreeze from the last few weeks.
