Points saillants

An additional 10cm is possible tonight, but this will not affect the danger ratings. Another significant input is needed before danger ratings change. Remain vigilant with terrain choices as potential for large avalanches is still possible.

Problèmes avalancheux

    These hard windslabs are between 10 and 25cm deep. Any new snow may hide these windslabs that up until recently have been active. It may still be possible to trigger this layer in select features from a thin edge of the slab.

  • Deep Persistent Slabs

    • Alpin

    Although the forecasted precipitation didn't materialize, deep persistent slabs are still a concern. This condition represents low likelihood but high consequence situation. Be vigilant in terrain choices.
