Kernpunkte

Although it may seem like spring is here, the winter snowpack has not yet gone through a serious melt freeze. Large avalanches and close calls have been reported all week. See photo of West Bowl from today. It is still time to place safe!

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    1–2
    The storm snow from the last few days has been blown into wind slabs and there are very large cornices. These slabs can be easily triggered and may result in an avalanche stepping down to deeper weaknesses.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe

    The Valentines surface hoar layer and the weak basal depth hoar have both been sliding layers for large avalanches over the last three days. Steep unsupported slopes, thin rocky areas and steep solar aspects are the most likely areas to trigger.
