Kernpunkte

You could trigger an avalanche today in places where wind drifted snow has or is filling in near ridgetops and into gully features. Move cautiously around areas where visible blowing snow is accumulating. Consider opting for wind protected, forested slopes for less avalanche hazard and increased potential for softer snow surface conditions.

    Expect the location of wind slab to change as the day progresses. Identifying the slopes of concern will require identifying where blowing snow associated with shifting winds has filled in near ridgetop and gully features. Use clues such as visible blowing snow, scoured vs smoother snow surfaces, and snow surface cracking to identify slopes of concern. Exercise caution around slopes that appear to hold newly formed wind slab. While mostly small avalanches are expected today, avalanches large enough to bury or injure a person are possible in isolated areas.

    New snow amounts of 1 to 6 inches over the last 24 hours varied significantly by location rather than by elevation. This will have a direct effect on the presence or absence of unstable wind slabs today for any given location. The shift in wind direction from W to NE will redistribute new snow on the ground today, especially as wind speeds increase out of the NE as the day progresses. This morning, anticipate encountering fresh wind slabs focused mostly on N-NE-E-SE aspects from last night's W winds. Once increasing NE winds are scouring and redistributing snow on the ground, expect the focus of wind slab instability to gradually shift to SW-W-NW-N aspects.

    Either read the snow surface clues today or use wind protected terrain below treeline as a strategy to avoid the avalanche problem.
