New snow and wind are forming fresh, reactive wind slabs.

Seek out sheltered, shaded terrain for the best and safest riding.

    Expect small but reactive wind slabs to form in lee features throughout the day as new snow is redistributed by southerly winds.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

On Sunday, a few natural wind slabs (size 1-2) were observed in alpine terrain, some triggered by large cornice failures. Small (size 1) wet loose avalanches were observed from steep solar aspects with strong sun.

Looking forward to Tuesday, new snow and wind will build fresh wind slabs throughout the day.

Snowpack Summary

Up to 10 cm of new snow will arrive by Tuesday afternoon, accompanied by strong southerly winds. This new snow overlies a melt-freeze crust on solar aspects and lower elevations, wind-affected surfaces at higher elevations, and facetted snow or patchy surface hoar in sheltered, shaded areas.

A crust from early February can be found down 60 to 120 cm and has shown no recent reactivity.

The remaining snowpack appears to be well settled and bonded.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
