    Isolated pockets of wind slab could still be found in the alpine.

Confidence

Moderate - Uncertainty is due to the limited number of field observations.

Avalanche Summary

No recent avalanche activity has been reported. Information is limited at this time of year. Please consider submitting to the Mountain Information Network!

We suspect that small pockets of rider triggerable wind slab could be found in the alpine. As the sun comes out small wet loose avalanches are possible.

Snowpack Summary

Up to 10 cm of recent storm snow has formed pockets of wind slab over old wind effected surfaces. Below this The upper snowpack contains several crusts that extend to mountain top on solar aspects.

The snowpack below treeline is thinning quickly.

Cornices are very large and exposure to slopes beneath them should be minimized, especially if the weather is sunny, warm, or windy. The 

Terrain and Travel

  • Carefully evaluate steep lines for wind slabs.
  • Minimize your exposure time below cornices.
  • Avoid sun exposed slopes, especially if snow surface is moist or wet.
