Points saillants

Avalanche danger is LOW for all elevations and aspects. Normal caution is advised. Long sliding falls on exposed rain crust are possible near and above treeline in wind scoured areas, especially on N-NE-E aspects.

    Avalanche concerns at this time are few. Triggering a small isolated unstable wind slab is unlikely but not impossible today, especially for those pushing the envelope in complex or extreme terrain. A more likely hazard to encounter today in exposed rain crust in wind scoured areas near and above treeline. Travel on or above areas of exposed rain crust opens up the possibility for long sliding falls.

Avalanche Discussion

Observations made yesterday on Silver Peak (Pole Creek area) and on Round Top Peak (Carson Pass area) revealed no evidence of instability. Recently formed wind slabs 6 to 8 inches deep were noted in lee areas, with no associated signs of instability. In wind scoured areas, exposed rain crust exists at the snow surface. In wind protected areas below treeline, a few inches of recent storm snow exist on top of rain crust.
