In sintesi

Keep an eye out for blowing snow. If you observe wind transport wind slabs could become more reactive.

    Isolated wind slab exists on alpine features near ridge crests. Ongoing snowfall and southerly winds could increase the size and likelyhood of wind slab avalanches.

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

If you do go into the backcountry, consider submitting a Mountain Information Network report.

Snowpack Summary

Ongoing snowfall accompanied by southerly winds could add to the wind slab problem.

A crusts can be found down around 50 cm on terrain below 1200 m, except on wind scoured slopes where it could be on the surface.

The snowpack is now above threshold for avalanches on smooth slopes at treeline. The snowpack in general is shallower than usual for this time of year and early season hazards are still a concern.

Check out this MIN from our field team that summarizes conditions at Fraser Chutes.

Terrain and Travel Advice

  • Use ridges or ribs to avoid areas of wind loaded snow.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
