Snowpack Summary
Windslabs forming in alpine and treeline areas starting late Wednesday with drifts up to 30cm deep in the lee. These slabs will continue to build overnight and should be easy to trigger by Thursday. This new snow overlies a weak, facetted base which produces test failures on the Oct 26 melt-freeze crust 30-40 cm above the ground.
Avalanche Summary
No new avalanches reported today. Sunshine Village reported that the windslabs were just starting to become stiff enough to create a soft slab late in the afternoon.
Confidence
Forecast snowfall amounts are uncertain on Thursday
