Avalanche Summary

No new avalanches have been reported in the region. Please post your observations to the Mountain Information Network.

Snowpack Summary

Below a thin skiff of new snow from Saturday night, a melt freeze cycle has allowed for surface crust formation down to about 1500 metres as of Sunday morning. The snowpack is generally well settled and strong, but basal weaknesses in the far north of the region remain a concern. With that said, the possible triggers for deep weaknesses in this part of the region are likely limited to large cornice falls.

Problems

Cornices

Where cornices exist, they have become unstable should be avoided. The likelihood of cornice falls will increase with daytime warming and solar exposure.

Avoid traveling on slopes that are exposed to cornices overhead.Stay well to the windward side of corniced ridges.Be aware that cornice releases have potential to trigger deep slabs.

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