Points saillants

If the sun comes out, solar exposed slopes are likely to experience soft slab releases and sloughing.

    SW winds are creating new wind slabs primarily in the alpine but also in exposed treeline locations. These slabs will be reactive even if they do not have preserved surface hoar beneath them.

  • Persistent Slabs

    Recent natural avalanche activity has declined but this snowpack weakness remains very touchy and easily collapses with skier presence.

  • Storm Slabs

    Strong solar radiation is tightening the recent storm snow on solar aspects. Forecast warm temps with continued solar effect is expected. Ice climbers on solar aspects should expect soft slabs, snowballing and sloughing in the PM.
