Points saillants

MODERATE avalanche danger will exist in near and above treeline areas due to lingering wind slabs.  LOW avalanche danger will be in below treeline areas.  Early season conditions exist with a thin snowpack and numerous exposed and barely covered obstacles.

    Wind slab instability could linger in near and above treeline areas.  Recent heavy snow and strong winds have built out large wind slabs and cornices in wind loaded terrain.  These wind slabs could remain active today and be human triggered.  Look for signs of recent wind slab avalanches, large cornices, wind pillows, and snow surface scouring as clues to where wind slabs may exist.  

Avalanche Discussion

* Natural and human triggered wind slab avalanches along with cornice fall reported from Tamarack Peak (Mt. Rose area).

* Light rain reported up to 8000' on Luther Pass with heavy dense snow.

* Snowpack above 8000' is generally 3 to 4.5' deep of thick dense snow.  Snowpack below 8000' is shallower and varies due to snow levels.
