Highlights

The melt freeze crust may be weaker at lower elevations on Sunday due to mild overnight temperatures.

    Spring conditions exist with a strong melt freeze crust that will deteriorate rapidly with warm sunny conditions. Expect loose snow avalanches to size 2 below treeline on steeper slopes by mid-day.

  • Deep Persistent Slabs

    Large triggers such as cornice failure or serac fall can trigger very large avalanches. Recently, ice fall released a large slab avalanche on a steep north facing glacial slope on Mt Andromeda.
