Points saillants

Cool fairly benign weather until Sunday will mean no real change in the snowpack. Low elevation areas are weak with no slab. Deep persistent instabilities are still the major concern and cautious terrain selection is dictated. JBW

Problèmes avalancheux

    1–2
    There are some small fresh wind slabs and ripe cornices that could be triggered on lee features. In some cases the slabs may be enough to trigger the deep basal instability.

    The basal weakness of depth hoar and October crust can still be triggered by light loads in the right location. Steep high consequence slopes should be avoided. Stick to moderate angled terrain with a thicker snowpack.
