    Yesterday's wind created slabs on all eastern aspects. Some isolated natural activity suggests these are easily triggered. Be cautious in steep terrain.

  • Persistent Slabs

    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible

    The windslabs sitting on the crust are a concern on steep, open areas at upper treeline.

  • Deep Persistent Slabs

2 avalanches were noted: A sz2 on a steep E aspect & a sz2.5 on a steep, E asp in the alpine.

Snowpack Summary

Forecasters made it up to 2300m today to inspect the alpine. The snow depth was 165cm's. The Dec 13th crust was there, but weak and decomposing. Stabillity tests showed a weakness down 50-60cm's on this crust. As expected, the winds have created windslabs 2400m and above. At lower elevations, the warm temperatures from yesterday did not have a huge impact. No new crusts formed.
