Avalanche Summary
No new avalanches observed.
Snowpack Summary
10cm of new snow fell overnight, covering various surface conditions. The December 15th surface hoar layer is widespread and is developing as an avalanche problem. It is most reactive at treeline and in sheltered alpine areas. November crusts are found down 60-90cm and are currently bonding well. Snow depths are below average at lower elevations.
Weather Forecast
The ridge of high pressure is finally breaking down. Early morning snow will subside to flurries with mix of sun and cloud and trace accumulation today. Freezing levels rise to 1200m, alpine temps reach -6.0 and light westerly winds will gust to 40km/h at ridge line. Warm fronts bring 10cm on Sunday and up to 30cm on Tuesday to Wednesday.

After a long dry spell, 10cm of new snow has fallen on a crust on solar aspects and widespread surface hoar. The surface hoar layer will be reactive today around treeline where buried crystals are large. Small skier triggered slides are very likely.
