    The recent storm snow (up to 35 cm in Kootenay) 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.

    Both the basal facet layer and the Feb 12 surface hoar are still surprising us a with isolated large avalanches, some being triggered by skiers. The terrain of most concern are weak, shallow and rocky snowpack areas.
