Points saillants

Cold snow is available for transport, moderate winds will build wind slabs directly lee of ridges and high points at upper elevations.

Don't commit to steep slopes if snow feels dense.

    Cold surface snow is available for transport by forecasted moderate west wind developing small wind slabs. Triggering these winds slabs is more likely directly lee of ridges and high points.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary

No new avalanche activity reported.

Human-triggered avalanche activity has decreased as recent storm slabs continue to settle. However, cold surface snow remains available for transport, and forecasted moderate westerly winds may form small wind slabs in exposed terrain features.

Freezing levels are expected to rise through the day and into Tuesday. As temperatures increase, the likelihood of wet loose avalanche activity will also increase.

Snowpack Summary

Recent storm snow has been redistributed by variable direction, moderate winds at upper elevations and remains unconsolidated in sheltered terrain.

Roughly 120 to 140 cm of settling snow sits on the December 16 crust.

At lower elevations this recent snow overlies bare ground.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
