Points saillants

Light accumulations expected Tuesday night, but not enough to change danger rating. New snow from last night refreshed surface, and improved ski quality.

    10cm very low density snow fell last night. At high elevations a light SW-NW wind has redistributed storm snow into lee areas.

  • Deep Persistent Slabs

    The weak base of depth hoar and facets is now less sensitive to human triggering. We have now entered a period of "low likelihood - high consequence". Shallow and faceted areas are likely trigger points.
