Periods of snow expected wednesday with forecasted accumulation of up to 5cm. Temperatures will remain steady with daytime highs at treeline elevation of -5.0. Freezing levels will hover near valley bottom. Light SW wind with moderate gust at treeline and above.

Snowpack Summary

Below 1700m there is no significant snow. Above 2000m an early winter snowpack exists, snow depths range from 30 to 100+ cm depending on aspects and exposure to wind. A series of crusts have develop a supportive snowpack allowing for good ski travel. Wind effect to the recent snow has loaded specific slopes in the alpine, expect this to continue.
