Avalanche Canada
Avalanche Danger will largely be driven by the wind over the short-term. North winds will deposit any loose snow into new wind slabs through reverse-loading. Look for higher quality riding in sheltered terrain features at lower elevations.

Snowpack Summary
In general, the snowpack is highly wind affected resulting in a wide variation in snowpack depths. Depths at treeline range from 50 to 125cm.
Upper Snowpack
20cm of loose snow will be redistributed by north winds and deposited into wind slabs.
Mid-pack
Generally well settled. A mid-November crust and facet layer is down approximately 60cm from the surface and is reportedly bonding well.
Lower-pack
Weak sugary snow (basal facets).

Terrain and Travel Advice
- Watch for areas of hard wind slab on alpine features.
- Wind slabs are most reactive during their formation.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
Problems
Wind Slabs
A good amount of north wind is forecast for the coming days. This will result in reverse loading and wind slab formation in places we don't normally expect it. Pay attention to the snow beneath you and watch for signs of instability including shooting cracks and stiffer, drum-like snow. This will most likely be found below ridge lines on the side walls of steep gullies.
