A skiff of forecast snow isn't expected to form much of a new avalanche problem, but it may obscure recent wind loading. Carefully evaluate your line for wind slab hazard before committing to it.

Weather Forecast
Monday night: Cloudy with isolated flurries. Light west winds.
Tuesday: Cloudy with scattered flurries bringing up to 5 cm of new snow, continuing overnight. Light to moderate west winds. Treeline high temperatures around -1 with freezing level remaining near 1200 metres.
Wednesday: Diminishing cloud with isolated flurries. Moderate to strong northwest winds. Treeline high temperatures around +3 with freezing levels rising to 3000 metres.
Thursday: Sunny. Moderate to strong northwest winds. Treeline high temperatures around +5 with freezing levels over 3000 metres.
Avalanche Summary
Numerous wet loose natural and skier triggered avalanches were observed on Friday at lower elevations. At treeline and above several wind slab avalanches to size one were reported on north aspects. Lingering wind slabs like these remain a concern for Tuesday, particularly at higher elevations.
Snowpack Summary
Thin crusts from warm temperatures and sunshine now likely exist on all aspects at treeline and below as well as on solar aspects in the alpine.Â
Beneath the surface, up to 20 cm of moist snow from Friday exists at treeline and below. Above this elevation it fell as dry snow. This overlies a melt freeze crust that likely extends to the top of treeline. Below this crust 20 to 60 cm of dry snow sits above another thick and supportive crust that extends to mountain top. At upper treeline and alpine, facets and surface hoar may be found above this crust.
The middle and base of the snowpack are well settled and strong.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- Be alert to conditions that change with elevation and wind exposure.
Problems
Wind Slabs
Rider triggerable wind slab could be found near ridge crests at treeline and above. Larger avalanches are possible in alpine terrain and upper treeline where facets exist above the late January crust.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
