Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Very Likely
    Size
    1–4
    Sustained westerly winds have encouraged the slab development since yesterday. These will be found sitting on top of the buried hardslab in immediate lee and extending well below ridge lines. Caution on steep lee features.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size
    2–6
    Thin areas near the transition to deeper snow pockets or hidden shallow areas are the trouble spots for this layer. Assess this layer carefully and look at the size of the terrain you are close to. Full depth avalanches are a possibility.

Confidence

Fair - Intensity of incoming weather systems is uncertain

Weather Forecast

Winds decreasing in the next 24hrs, but keeping a westerly flow (at 3000m). Temps will hold steady at the -5 range. Overnight Thursday/Friday will see a mild front pass through with a spike in the winds and 7cm's of new snow. The big news is coming Friday night. A system will arrive bringing strong to extreme winds (1500m & 3000m respectively). Right now almost 30cm's of snow is predicted to arrive with the winds. Good news!
