Highlights

Watch for rapidly changing conditions in the afternoon sun.

Back off sun exposed slopes as they become moist, natural activity is likely.

Avalanche problems

    Expect to find deeper and more reactive deposits around ridgelines, these may remain triggerable by riders for several days.

  • Loose Wet

    Loose snow can be found in wind sheltered areas, and may become a hazard in steep terrain features. Manage your sluff, and always have an exit plan.

    Expect loose wet avalanches on sun affected slopes in the afternoon.

Terrain and Travel Advice

  • Give the new snow time to settle and stabilize before pushing into bigger terrain.
  • Use appropriate sluff management techniques.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Brief periods of sun could quickly initiate natural avalanche activity.
