    The recent storm snow has settled quickly. We have limited observations of how this new snow is bonding to the old surface. The main concern for this problem is at upper elevations predominately on Northerly aspects.

    Treeline and below will likely deteriorate by the PM, and higher on solar aspects. This includes breakdown of crusts and/or warming of the 5-15 cm of recent storm snow.

Weather Forecast

Decent refreeze forecasted for Thursday night with a clearing trend into Friday. Slightly warmer temps Friday with freezing levels climbing to 2200m. Upper elevation winds are expected to stay in the light to moderated range from the SW.

Snowpack Summary

Recent storm snow has settled quickly. Where this new snow has not melted away it overlays crusts that exist on all aspects below 2300m and high into the alpine on solar aspects. High N aspects still hold dry powder and some wind effect on lee slopes. Crusts are breaking down and reforming almost daily depending on solar input and freezing levels.

Avalanche Summary

No new avalanches observed or reported today.
