Lo esencial

The surface hoar under the new storm snow remains touchy. People and solar effect are two likely triggers for new avalanches right now.

Problemas de aludes

  • Wind Slabs

    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño

    Continued Mod-strong NW winds are creating 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

    The recent widespread avalanche cycle was the result of our Feb.14 surface hoar layer failing below the rapid load of new snow. Natural activity has declined partly because so many areas have already avalanched. Areas that have not are suspect!

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