The sun will be out and the freezing level is forecast to be higher than it has been in the past few days. As a result there may be an increase in wet loose avalanche activity on steep terrain facing the sun.
The sun may be out for extended periods so expect to see an increase in thin loose wet avalanche activity on steep terrain facing the sun.
A weak layer of facets exists near the base of the snowpack. The likelihood of human triggering is low given the layer's depth, but large triggers such as cornice failures or smaller avalanches in motion have the potential to produce very large avalanches with surprisingly wide propagation. Suspect terrain for human triggering includes steep, shallow, and rocky terrain where the snowpack transitions from thin to thick.
There was rider triggered size 2 avalanche reported on Saturday in the Hasler area. Check out the MIN report here.
Recent moderate winds from the northeast may redistributed recent new snow and develop small, isolated wind slabs directly lee of ridges. These new wind slabs sit over a crust on solar aspects and on high north-facing terrain possibly over facets and/or surface hoar.
The middle of the snowpack is generally well-settled and strong.
A weak layer of large facets is found near the base of the snowpack. This layer could still be a concern in very shallow snowpack areas.
