Points saillants

Wind slabs at upper elevations may be reactive to rider triggering.

Rising freezing levels and brief periods of sun could trigger wet loose avalanches.

    Rising freezing levels could initiate natural wet loose and possibly wet slab avalanches.

Avalanche Summary

No new avalanche reports received Tuesday.

Wind slabs may exist and be reactivce to rider triggering on north through east facing slopes just below ridgetop. With rising freezing levels, expect conditions to change rapidly, and natural wet loose avalanches or wet slabs are possible at treeline and below.

Snowpack Summary

Up to 20 cm of new snow may exist above 1600 m. This sits above a supportive crust that overlies wet snow. At elevations below 1500 m, the snowpack is isothermal to ground.

Terrain and Travel Advice

  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Be careful as you transition into wind-affected terrain.
  • Be alert to conditions that change with aspect and elevation.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
