Points saillants

Wind slabs are main concern, but with persistent cold temperatures, watch for surface faceting and loose snow chasing you down a run.

Bear in mind that even a minor injury can have serious consequences in the cold. Pack the extra jacket!

    Suspected presence on all aspects in the alpine and in open, exposed tree line features. With cold temperatures, wind slabs are expected to loose its energy and become less reactive.

Snowpack Summary

Cold temperatures promoting surface facetting. HST (25-55cm) bonding well to underlying surfaces (facets, surface hoar and wind affected snow depending on location). Wind slabs in the ALP and exposed TL. A well settled mid-pack, except in areas with a shallow snowpack, can be found throughout the forecast region. Variable HS (90-200cm).

Avalanche Summary

No avalanches observed or reported in the last few days.
