Lo esencial

While the overall danger is low, you'll need to watch for small stubborn pockets of wind-loaded snow, especially around ridge crest and in extreme terrain.

    Thin wind slabs may remain sensitive to human triggering, especially in more extreme terrain.

    Although temperatures remain seasonally cool, the sun packs a lot of punch this time of year. Take care to avoid being on or underneath south facing slopes that are baking in the sun, especially after lunch.

Avalanche Summary

Very little avalanche activity has been reported over the last five days.  

Snowpack Summary

A light dusting of snow rests on 30 cm of settled and bonded storm snow from last weekend. A sun crust is present about 30 cm below the surface on solar aspects.  

A strong mid-pack sits on top of weak facets near the ground.

Cornices are very large and exposure to them should be minimized, especially during warm or windy weather.

Terrain and Travel

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Cornices become weak with daytime heating or solar exposure.
