In sintesi

The avalanche danger should remain LOW today on all aspects and elevations. Today's light snow accumulation and light winds should not create significant avalanche harzards unless more snow falls than forecasted. Continue to practice safe travel habits and thoughtful decision making when traveling in the backcountry.

    The 1-2 inches of new snow and the light winds forecasted for today should not create significant slabs on top of the stable snowpack. Without significant slab formation, avalanche activity will remain unlikely. This new snow will fall on top of frozen crusts on all aspects creating "dust on crust" conditions. Some minor sluffing of the new snow may occur on steep slopes, but with only 1 to 2 inches of snow to work with, these sluffs should remain small and isolated. Some small, shallow, and isolated wind drifts may also form in the most wind loaded areas, but these should not pose much threat to backcountry travelers due to meager snow accumulation amounts and light winds. If more snow falls than forecasted and the winds grow stronger than forecasted, some small wind slabs may form in areas that typically experience heavy wind loading.

Avalanche Discussion

Yesterday on Chickadee Ridge in the Mt. Rose backcountry, observations continued to show a stable snowpack capped by frozen crusts on the northerly aspects and melt-freeze conditions on southerly aspects. Some softening occurred on the sun exposed southerly aspects by 11 am, but increasing cloud cover limited the amount of wet snow that formed. Snowpit data on the northerly aspects showed that the snowpack continues to gain strength.
