In sintesi

Daily avalanche bulletins have concluded for the season, but the possibility of avalanches is still present.

The Spring Conditions page offers guidance on mountain travel during this transition period.

Please continue submitting any snow/mountain travel observations on the Mountain Information Network.

    Monitor the quality of the overnight crust refreeze, daytime temperatures, and solar inputs. The likelihood of loose wet avalanches will increase as temperatures rise and even short periods of solar inputs can result in increased avalanche activity.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.
  • We are uncertain about how the timing or intensity of warming will affect the snowpack.

Avalanche Summary

Loose wet avalanches will be the norm as we move through the Spring-time warm-up.

Wind slab and storm slab avalanches are possible in high, North-facing terrain with the passage of storm fronts.

Glide avalanches from steep, unsupported slopes at all elevations are possible as the mountains shed their winter coat.

Cornice collapses will increase in frequency as the temperatures continue to rise.

Snowpack Summary

The snow surface likely consists of a mix of hard melt-freeze crust and dry snow depending on aspect and elevation. Sun-exposed slopes may undergo daily melting and freezing whereas northerly alpine slopes could remain dry with potential slabs.

Crust layers persist in the middle to lower sections of the snowpack. These crusts could provide sliding layers when/if things warm up dramatically.

Terrain and Travel Advice

  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
