Regions: Babine, East Stikine, Hudson Bay, Kispiox, Microwave-Sinclair, Northwest Inland, Telkwa.

Highly variable snow depths and surfaces due to the recent wind effect. Until we get more snow, the best riding will be in shelter features with a deeper snowpack.

Confidence

High

Avalanche Summary

No other recent avalanche activity has been reported in the region.

Thank you for the MIN reports! They are extremely helpful to us! If you head into the backcountry please submit a MIN report!

Snowpack Summary

In general, the snowpack is highly wind affected resulting in a wide variation in snowpack depths. Depths at treeline range from 50 to 125cm.

Upper Snowpack

10-20 cm of recent low density snow in areas sheltered from the wind. Isolated pockets of wind slab are hard to find but still exist in wind-exposed terrain at higher elevations.

Mid-pack

Generally well settled. A mid-November crust and facet layer is down approximately 60cm from the surface and is reportedly bonding well.

Lower-pack

Weak sugary snow (basal facets).

Weather Summary

Tuesday Night

Mostly cloudy with no precipitation. Generally light northwest winds and temperatures around -10 C in the alpine.

Wednesday

Mainly cloudy, with no precipitation. Alpine temperatures in the -5 to -10 C range. Generally moderate westerly winds with strong gusts in the alpine.

Thursday

Mainly cloudy, with no precipitation. Alpine temperatures in the 0 to -5 C range, with the potential for a slight temperature inversion. Moderate to strong northwesterly alpine winds.

Friday

A mix of sun and cloud, with a chance of flurries. Alpine temperatures range from 0 to -10 C and moderate winds from the northwest.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Wind slabs are most reactive during their formation.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Avalanche Problems

Wind Slabs

In exposed alpine terrain you will find a variety of wind-effected surfaces, including scouring, sastrugi, and hard wind slab. Human-triggering wind slabs on isolated or extreme features are unlikely but not impossible. Despite the lack of loose snow for transport, watch for new wind slab development as we see increasing northwest winds over the coming days.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
