No new avalanches were reported on Friday.

NOTE: Observations are currently very limited in this region.

Snowpack Summary

Up to 15 cm of recent snow in the alpine and strong variable wind may have formed small wind slabs on a variety of aspects at upper elevations. The recent snow sits on top a crust.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
