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

Avalanche 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.

Likelihood: Possible

Expected Size: 1 - 2

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.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3.5
