In sintesi

Watch the wind closely; when it picks up, wind slabs are likely to form.

Avalanche Summary

No recent avalanches have been reported.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

10 to 25 cm of soft snow is covering a hard crust. At upper elevations, this newer snow has been blown by variable winds, creating wind slabs on lee slopes.

These slabs should bond quickly within the next few days. If you observe blowing snow, it indicates that new slabs are forming, and areas where the snow is accumulating should be avoided.

The mid and lower snowpack are not concerning at this time, and are made up of various hard layers and crusts.

Terrain and Travel Advice

  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
  • Wind slabs are most reactive during their formation.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
