Cornices are weakening and starting to collapse with the wide temperature fluctuations over a day. They are completely unpredictable, so be aware of the overhead exposure.

Weather Forecast

Cool temperatures, moderate wind and broken skies expected for the day on Sunday. Only a small dusting of snow expected but barely enough to get excited about!

Snowpack Summary

A supportive mid pack consisting of rounded and facetted layers is bridging the weak depth hoar/facet layers that make up the lower snowpack. Some wind slabs are developing in sheltered alpine locations.

No new avalanches reported

Avalanche Problems

Wind Slabs

Strong winds are redistributing snow into slabs on sheltered aspects and cross loaded features in the alpine.

Be cautious as you transition into wind affected terrain.Use caution in lee areas. Recent wind loading have created wind slabs.

Aspects: North, North East, East, South East, South, South West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Natural and human triggering is unlikely but it is still a good practice to avoid steep, open, rocky slopes with a shallow snowpack.

Caution around convexities or areas with a thin or variable snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
