Points saillants

Watch out for avalanche activity due to warming, as a temperature inversion will effect upper elevations.

Windslabs exist near ridgelines and in lee features, use caution in wind loaded terrain.

    A temperature inversion may make this problem more prevalent at higher elevations

Confidence

Moderate

  • Uncertainty is due to difficult to forecast freezing levels.

Avalanche Summary

Significant natural wind slab avalanches observed in extreme alpine features over the past week. Dry loose avalanches observed during the previous storm cycle.

Snowpack Summary

Up to 40 cm of new snow has been redistributed by moderate to strong winds. Under which sits a melt freeze crust. Below this crust, lies 50 cm of settling snow. The lower snowpack consists of refrozen rain effected layers, which is still moist at ground in places.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
