Kernpunkte

Lingering, shallow slabs of wind deposited snow remain a concern today. Move carefully around areas where wind drifted snow has filled in, mainly on slopes below or adjacent to cornice features. Small wet loose avalanches could become a concern later today on sun exposed slopes in response to daytime warming.

    New snow combined with mainly SW to W winds over the past 24 hours drifted snow, filling it in along the downwind side of ridgetops and into gully features. Cohesive slabs of wind drifted snow were unstable yesterday and may linger today. These wind slabs are expected at less than 1 foot in thickness, existing mainly on slopes below or adjacent to cornice features.

    Use clues such cornices and locally deeper areas of wind drifted snow to identify the locations where wind slabs exist. Warming conditions today could increase the sensitivity to triggering in some locations. Move around these areas with caution.

    Following a chilly start to the morning, air temperatures are forecast to warm above freezing today and cloud cover is expected to thin. This could allow for some small wet loose avalanches to occur in steeper, sun exposed terrain. Roller balls initiating off of rocks and trees will be the first signs of problematic warming. Exercise caution and consider the consequences of down slope hazards such as rock, trees, and cliffs if choosing to travel in steep terrain where roller balls and/or pinwheels are present.
