  Strong NW winds over the last 24-hours have created windslab conditions in open areas at higher elevations. With 80cm of recent storm snow available for transport, expect deep slabs in leeward areas.

  The Valentine surface hoar down 75 cm is overlain by a stiff slab and remains very sensitive to triggers. This problem is actively producing large avalanches in many locations and will remain so for the forecast period. Avoid all steep open terrain.

  The deep facets in the Rockies snowpack are awake again, and are responsible for numerous size 3 and 4 avalanches in the last 48-hours. Avalanches starting in the upper snowpack are stepping down into the base of the snowpack.
