Avalanche Forecast
Regions: Boundary, East Stikine, Howson, Kitimat, Nass, Ningunsaw, Northwest Coastal, Rupert, Seven Sisters, Shames, Stewart, West Stikine.
Watch for signs of instability. New rider triggerable wind slabs will likely form throughout the day and may overlie facets making them more reactive.
Confidence
Moderate
Snowpack Summary
Up to 25 cm of recent snow accompanied by southerly winds has formed wind slab in exposed terrain at treeline and above. At lower elevations, where  some of this precipitation may have fallen as rain, moist snow or a crust will be present.
A layer of surface hoar may be found about 30 to 40 cm deep in treeline and open below treeline areas sheltered from the wind. A hard crust and associated facetted grains from December is about 60 cm deep at treeline elevations.
The rest of the snowpack is strong and well-settled.

Terrain and Travel Advice

- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Approach steep open slopes at and below treeline cautiously, buried surface hoar may exist.
Avalanche Problems
Wind Slabs
Rider triggerable wind slab will form throughout the day. These slabs will be more reactive where they overlie facets.
