Avalanche Forecast
Regions: Glacier.
So... cold.
Make sure you have the gear to stay warm if any unexpected delays occur.
Confidence
High
Avalanche Summary
Natural avalanche activity has eased, however human triggering remains possible.
Neighboring operations are still reporting rider & remote triggered avalanches on the Jan 30th layer.
Snowpack Summary
Cold temperatures are faceting out the isolated pockets of wind slab, decreasing the reactivity. Widespread wind effect is still prevent in exposed terrain.
A weak layer of surface hoar, facets and/or suncrust (Jan 30th drought layer) is 30-50cm down from the snow surface.
The Jan 7th layer is down 50-80cm, and is comprised of surface hoar in sheltered areas and/or a thin crust on steep S aspects.
Weather Summary
The arctic ridge is firmly planted. Mainly sunny skies and cold temperatures are forecast into the foreseeable future.
Tonight Clear periods. Alpine low -21°C. Ridge wind NW 15km/hr.
Tues Mix of sun and cloud. Alpine high -16°C. NW wind 10-20km/h.
Wed Mix of sun and cloud. Alpine high -16°C. Wind SW 10-20km/hr.
Thurs Mix of sun and cloud. Alpine high -9°C! Wind SE 10-20km/hr.
Terrain and Travel Advice
- Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
- Keep in mind that human triggering may persist as natural avalanches taper off.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Avalanche Problems
Persistent Slabs
20-40cms of snow overlays a buried persistent weak layer. This weak layer is consists of surface hoar, facets and/ or a suncrust. It will be most reactive where there is a settled, cohesive slab over top. This layer is still producing easy results in snowpack testing.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely
Expected Size: 1 - 2.5
Wind Slabs
Isolated pockets of windslab are faceting with the cold temperatures. Be aware that a surface wind slab could step down to the Jan 30th persistent weak layer.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Unlikely
Expected Size: 1 - 2
