In sintesi

Avalanches will be unlikely on Saturday. Weak snow exists in the upper snowpack, especially on northerly facing slopes at the upper elevations. Monitor slopes for signs of unstable snow and consider consequences of avalanches in steep terrain.

    This is a new problem to the forecast. There are multiple layers of weak snow in the upper pack (top 12 - 20") and primarily on northerly facing slopes at the mid and upper elevations.  We are still gathering information on the distribution of this problem. Initiating a persistent slab avalanche is very low likelihood until we get a substantial load of new snow, but something to keep in mind. Use your observation/pit digging skills to investigate where these weak layers may be lurking.

    Extended column test on a NNE slope at 7870'. Propagation occured on a layer of rounding facets down 12". Initiating an avalanche on this layer is unlikely until future storms add more load to the snowpack.
