Weather Forecast

Moderate SW winds and day time temperatures rising to around freezing. No significant snowfall forecast.

Snowpack Summary

Alpine windward terrain is scoured but lee gullies are wind loaded.  Where there is snow the mid-layer is well settled, but overlies a sleeping dragon as a deep persistent layer at the bottom of the snow pack.

Avalanche Summary

Loose dry avalanches noted on steep terrain.
