In sintesi

We are still in transition from winter to spring. Large deep natural avalanches on steep northerly slopes and skier triggered avalanches in thin areas have been observed nearly every day this week. There a good choices available but use caution.JBW

Problemi valanghivi

    Fresh wind slabs and large cornices have formed in the alpine. Be extra careful in the immediate lees of alpine ridges, and on steep convex rolls and beware of the potential for cornice triggers above you.

    The recent storm snow is sitting on several sun-crusts, which can provide a good sliding interface. Daytime heating & solar affect can increase the hazard on slopes overhead or on steeper terrain where buried crusts exist.

  • Deep Persistent Slabs

    Several large deep avalanches have been observed over the last few days. These are failing near the ground, on glacial ice, or on the Feb 14 surface hoar. These are likely unsurvivable avalanches and do not inspire great confidence in the snowpack.
