    Watch for fresh wind slabs at higher elevations where dry snow can be found. Wind slabs likely sit over a crust, increasing reactivity.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

No new avalanches were reported.

Suspect wind slabs to be forming at upper elevations that may be human triggered.

Snowpack Summary

Recent storm snow is being redistributed by strong southwest winds, forming fresh wind slabs over a crust that developed earlier in the week and can be found up to 2200 m.

A mid-November crust with sugary, faceted snow above it persists in the snowpack but appears to be improving, particularly in areas where a strong surface crust is present.
