In sintesi

The avalanche danger remains LOW for all elevations. Continue to use normal caution while traveling in the backcountry.

    If any rain does fall today, it could help soften some snow surfaces. Otherwise, cloud cover and slightly cooler temperatures should keep most snow surfaces frozen. In the areas that do receive rain, limited precipitation amounts should not be enough to create more than small wet snow instabilities. If light snow falls at upper elevations, some "dust on crust" conditions may result. Variable firm snow surfaces still exist in many places including frozen sun crusts on solar aspects, icy rain crusts on wind-scoured slopes, and uneven firm wind textures on exposed slopes. While avalanche activity remains unlikely, the firm surfaces could make travel challenging and allow for other hazards including long sliding falls.

    Matching backcountry travel plans to the skills of your group can help find enjoyable and safe recreation opportunities. Maintain awareness of the conditions and terrain to help find the best conditions for your crew. Stop and talk to each other to make sure everyone is on the same page and comfortable with the current conditions and terrain selections. 

Avalanche Discussion

* Cloud cover kept most snow surfaces frozen yesterday. On the upper elevations of Stevens Peak and Castle Peak, observations revealed firm surface conditions ranging from frozen sun crusts on sun-exposed slopes to old icy rain crusts and uneven wind-textured surfaces on wind-scoured aspects. Some small patches of soft snow did exist on sheltered and shaded N aspects of Stevens Peak.

* Warm, wet, and sticky snow existed in lower elevation areas on Castle Peak and Stevens Peak yesterday. Ski cuts on steep rollovers on Stevens Peak did cause some small rollerballs and pinwheels.
