In sintesi

Dial back your terrain choices if you're seeing recent avalanches or cracking in the new snow.

Snowfall amounts vary over short distances.

    New snow and strong winds may have formed new wind slabs in lee terrain features. These slabs may not bond well with old snow surfaces. Assess for slabs prior to committing to consequential terrain.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

We haven't received reports of recent avalanches.

Looking forward, riders could trigger new wind slabs at higher elevations.

Please consider submitting a MIN to let us know what you're seeing out there.

Snowpack Summary

Below 1600 m, rain falls on an already wet snowpack. Above 1600 m, about 15 to 30cm of snow accumulated and is being blown around with strong winds. This snow may form wind slabs in lee terrain features near ridgetop, which may not bond well to an underlying crust.

A weak layer of facets above a hard crust is buried 50 to 70 cm deep. This layer hasn't produced avalanches since last week's warm weather.

Facets exist at the base of the snowpack in shallow areas.

The snowpack continues to melt at lower elevations.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Investigate the bond of the recent snow before committing to your line.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
