Avalanche Canada
North winds have arrived and are starting to move the new snow around. These winds are due to swap back to the SW on Sunday. Caution in lee features as these freshly formed windslabs are building on top of the Feb 3rd temp/rain crust. A nice sliding surface.

Avalanche Summary
A natural loose dry off EEOR triggered a small windslab lower down in the bowl.
Otherwise no new reports
Snowpack Summary
The recent storm snow is settling and now averages 10 to 20cm over the Feb 3 crust. With the sunny skies Friday, steep solar aspects now have a thin sun crust on the surface. Deeper down, the Feb 3rd crust is mostly supportive in the valley bottom and extends at least as high as 2500m. The bond at the storm snow - crust interface is mainly good, except on steep northerly aspects in the alpine where some previous sluffing was observed. Very isolated wind slab development has also been observed in the alpine in wind prone areas and on lee features. Ski quality is dust on crust in the alpine.
Weather Summary
Sunday will see flurries (not really accumulating to much) Day time high of -6, 20km/h SW winds and cloudy skies. Freezing levels to hover around 1600m

Terrain and Travel Advice
- In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
- Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
Problems
Wind Slabs
Saturday the wind picked up from the North and we expect to see freshly formed wind slabs in A-typical locations as this is a reverse loading pattern. (Winds form the N-NW)
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
This will still be an issue in areas that escaped the heat, as there is no previous crust to hold the snowpack together.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
