Reactive storm slabs will build through the day. Northeast aspects will likely see deeper slabs with wind loading.
Dry loose avalanches are likely from steep terrain features.
On Tuesday, a natural wind slab avalanche (size 1.5) was reported from a steep northeast slope at 2000 m.
With new snow and strong wind forecast, natural and human-triggered avalanches are likely on Friday.
Up to 25 cm of snow is forecast by Friday afternoon and will likely have a poor bond to the old snow surfaces. These consist of faceted snow, surface hoar in shaded wind-sheltered areas and a hard melt-freeze crust found on the snow surface on sunny slopes. At high elevations, the new snow buries the widespread wind effect found in wind-exposed terrain.
The mid and lower snowpack is strong.
