Lo esencial

Avalanche danger remains LOW for all elevations and aspects. Normal caution is advised. Expect increased avalanche danger Tuesday/Wednesday as a well advertised storm impacts the region.

    Generally stable snowpack conditions exist across the forecast area. There are no specific avalanche problems requiring specific management for travel in and below avalanche terrain beyond normal caution. Standard backcountry travel practices such as one at a time travel through or below avalanche terrain and avoiding grouping up in avalanche run out zones remains appropriate during LOW danger.

    In areas where the snowpack is 1 to 2+ feet deep, a structure of slab over relatively weaker snow below is often found. The relatively weaker, once faceted snow in most cases is rounding and gaining strength. Spacial variability exists. The degree of slab formation and the amount of rounding/faceting in the snow below the slab varies widely from one location to another.

Avalanche Discussion

Recent observations from the Mount Rose, Carson Pass, and Donner Summit areas indicate improving snowpack stability. Recent snowpit tests performed in areas with a slab over weaker snow structure and in areas of relatively greater faceting or slower rounding have not given indications of a problematic weak layer. A wide spectrum of snow surface conditions exist by aspect, elevation, and wind exposure. Recent warm air temperatures have caused melt in sun exposed areas. Bare ground has reemerged on numerous SE-S-SW aspects. Above treeline, wind scouring has also left behind a very shallow snowpack and areas of bare ground. On the wind protected NW-N-NE-E aspects, mixed conditions are found consisting of melt-freeze snow, breakable crust, and pockets of cold unconsolidated surface snow in the form of poorly developed near surface facets.
