If triggered, surface wind slabs may step down and involve this layer. Avalanche sizes could be surprisingly large if this happens.

Avalanche Summary
A couple small natural cornices triggered sluffs in steep terrain were observed. No slabs were pulled out.
Snowpack Summary
Recent snow has mostly facetted out providing good skiing. Wind effect has been mostly isolated to immediate lee and col features. We took windslabs out of the problem list as they don't seem to exist at the moment.
The previously mentioned buried windslabs are now conglomerated within the mid pack.
The weak basal facets are still a concern and have a potential to be triggered from thin snowpack areas which are still plentiful at this time. Stability has been improving but we are still avoiding steep thin features where triggering this weakness is still a possibility.
Weather Summary
Tuesday:
A mix of sun and cloud, day time high of -2 with 35km/h West winds at ridge top. Freezing levels will rise to 1700m.
More details can be found in the Mountain Weather Forecast.
Terrain and Travel Advice
- Be mindful that deep instabilities are still present in the snowpack.
