Kernpunkte

Avalanche danger remains LOW at all elevations on snow covered NW-N-NE-E aspects. Avalanche danger and snow cover are generally nonexistent on SE-S-SW-W aspects.

    While most data indicates that the snowpack can support itself and people recreating on top of it, a few isolated results indicating instability continue to occur. Persistent weak layers like those buried in the current snowpack often produce this kind of variability. Due to the nature of these weak layers and this variability, finding some unstable snow in the form of a small persistent slab on an isolated terrain feature on a NW-N-NE aspect is not impossible even though avalanche activity on a region scale remains unlikely. Continue to evaluate the snowpack before committing to a slope and employ safe backcountry travel practices like traveling one at a time and spotting partners from known safe zones outside of any avalanche path. Numerous rocks, trees, stumps, logs and other obstacles remain exposed and could easily injure people or break equipment.

Avalanche Discussion

Yesterday observations in the Mt. Rose backcountry east of Mt. Rose Meadows resulted in data consistent with other information collected around the forecast area. A shallow snowpack comprised mostly of weak facetted snow exists on the northerly aspects and almost no snow exists on the aspects facing the southern half of the compass. In this area similar to other areas, tests indicated that the snowpack can currently support itself and people recreating on top of it, but an additional snow load could still reactivate the buried weak layers.
