Avalanche Forecast
Regions: Babine, East Stikine, Hudson Bay, Kispiox, Northwest Inland, West Stikine.
Carefully assess terrain for wind slab as you gain elevation. Wind slabs will be more reactive where they overlie facets.
Confidence
Moderate
Avalanche Summary
On Tuesday our field team observed a few recent size one natural avalanches. These avalanches released in steep alpine features on northeast aspects. They also observed a few older size 2 avalanches that released during the storm.
If you are headed out into the backcountry please consider filling out a Mountain information Network report.
Snowpack Summary
Around 20cm of recent snow has been redistributed into wind slab on North and east aspects. In non-wind effected terrain this recent snow sits on a layer of facets formed during the cold snap. Below treeline the upper snowpack became moist on Monday and has now formed a new thin crust below 1000m.
A surface hoar and facet layer from early December, while spoty, can still be found down around 40cm.
In General snowpack depths are highly variable throughout the region.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Closely monitor how the new snow is bonding to the old surface.
- The best and safest riding will be on slopes that have soft snow without any slab properties.
Avalanche Problems
Wind Slabs
winds have been variable meaning that wind slab could be found on all aspects. Wind slab will generally be found in the alpine but may have formed in some upper treeline features.
New wind slabs have likely formed over facets. These slabs will remain reactive a little longer than usual as a result.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
