Snowpack Summary
Traces of new snow overnight on a supportive melt freeze crust exists on all aspects, BTL and solar aspects at TL and Alp elevations. Snowpack has yet to have a deep melt freeze cycle and basil weakness is still a looming hazard sensitive to large loads like your mum, and cornices.
Avalanche Summary
No new avalanches observed or reported.
Confidence
Intensity of incoming weather systems is uncertain on Wednesday
Problems
Storm Slabs
Possibility new snow with varied consistency depending on elevation. Slabs may be limited to TL elevations but depends on condition of old surface, which is quite varied across the region.
- Use extra caution on solar slopes, or if the snow is moist or wet.
- If triggered the loose wet sluffs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: All elevations.

Expected Size
Deep Persistent Slabs
This problem will require a large trigger, thin spots, increased loading or rapid day time warming.
- Avoid shallow snowpack areas where triggering is more likely.
- Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.
Aspects: All aspects.
Elevations: All elevations.
