Lo esencial

Low danger doesn't mean no danger! Early-season hazards such as rocks, creeks, and alders are abundant.

Be mindful of isolated pockets of wind slab lingering at upper elevations.

    Recent variable winds may have left isolated pockets of wind slab in wind-loaded areas such as cross-loaded slopes, areas of drifted snow behind ribs, gullies, and other terrain breaks.

Avalanche Summary

No recent avalanches have been reported, but observations are limited at this time of year. Please consider posting a MIN if you are heading out in the backcountry!

Isolated pockets of wind slab could exist in exposed areas. Low-density surface snow may sluff and run far in steep terrain features.

Snowpack Summary

Surface snow at treeline and above is variable, with soft snow in sheltered areas and pockets of firm, wind-affected snow in more exposed areas. A thin sun crust exists on steep solar aspects. Last week's 40 to 60 cm of settling storm snow sits above a rain crust buried mid-November up to approximately 2200 m.

The average snow depths at treeline elevation are anywhere from 70 to 100 cm.

Below treeline, the snowpack tapers significantly. Watch out for variable snow conditions and quality—early-season hazards such as open creeks, rocks, and stumps are abundant.

Weather Summary

Saturday Night

Mostly clear skies. 10 km/h west ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be cautious of buried obstacles, especially below treeline.
