Points saillants

Forecasters are still feeling that exposure to large overhead terrain should be avoided.  The lower half of the snowpack is weak.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Up to 30cm of new snow in the last three days. Wind effect was observed in the alpine, on lee features and cross loaded gullies. Moist snow was felt below 1900m and it is settling rapidly with warm temps. Good skiing can be found on shady aspects and sheltered areas. Numerous pits were dug in many areas of our forecast area and the most relevant observation was the weakness of the bottom 100cm of the snowpack (mostly facets and depth hoar).
