The cold temperatures at night have been just enough to keep the higher altitude snowpack locked up. Solar aspects are warming up during the day but not enough to increase the avalanche concerns. A little sunshine or warmer temperatures could change that quickly though.

There is still a layer down 90 cm or so that could be a concern for deep slab instability.  So far this layer hasn't shown any signs of instability but could produce a large avalanche if it fails. I'd recommend testing that layer before skiing or riding in avalanche terrain.

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
