Weather Forecast

Light snow overnight with moderate SW wind.  Seasonal  temperatures.  Clearing and colder temperatures expected later this weekend.

Snowpack Summary

Continued moderate SW winds building slabs in lee features and cross loaded gullies. Weak layers include; buried surface hoar (Dec 11) in sheltered NE aspects around treeline and the Nov 12 crust approximately 30cm from the ground. Generally, in the Alpine there is only snow in lee areas and the snowpack is faceted and weak. 

Avalanche Summary

Previous avalanche activity up to Sz 2 on N-NE-E slopes below ridgeline and to Sz 3 on a westerly aspect in steep, rocky, cross loaded terrain between 2400-2700m.  No new observations due to poor visibility.
