Snowpack Summary
A trace of new snow fell above 1900m last night. This will overly Sun Crust on steep East through West aspects and Temperature or Rain Crusts as high as 2200m on all aspects. Winds have created thin windslabs over these crusts in open areas Treeline and above.
Avalanche Summary
We are into a predictable pattern of daily heating that produces wet loose avalanches especially as the sun exerts it's effect on Solar Slopes. Several Cornice failures have been observed as a result of this heating as well and these should remain a concern for skiers seeking dry snow on NW to E aspects.
Confidence
Timing or intensity of solar radiation is uncertain
