Weather Forecast

We received up to 5cm of snow along with a bit of wind on Wednesday. Flurries are to continue with up to another 5cm by Thursday morning. Winds are expected to be moderate from the SW overnight and light westerly for Thursday. Temps will start out around -12c and warm up to -7c in the alpine.

Avalanche Summary

No new avalanches observed. Very limited observations.

Snowpack Summary

Up to 5cm of snow has fallen on Wednesday. The most interesting part was that the top 30cm of the snowpack felt like a soft slab and was widespread from tree line and above. This might of been caused by the recent winds or the warmer temperatures Tuesday night and Wednesday during the day. Either way, it felt slabby and we pulled back from steeper terrain. There are still a couple of buried wind slabs, the November crust and October facets near the base to think about.
