    Size
    2–4
    Natural activity is reduced; however, slopes that did not slide during March 6th avalanche cycle should be treated with caution. The buried surface hoar layer remains a concern. Solar effect is a likely trigger in the afternoon.

  • Storm Slabs

    Size
    1–3
    Variable direction moderate alpine winds continue to form slabs on lee aspects. 15cm last night makes for 70cm since march 12th. Triggering the slab has the potential to step down to the buried surface hoar layer 80-120cm down.

  • Loose Wet

    • Alpine

    Surface snow is responding to the strong solar radiation effect that this time of year brings to steep south and west facing slopes. Ice climbers should avoid exposure to overhead hazard during warm, sunny afternoon periods.
