Avalanche Canada
Incoming snow will be redistributed by winds and develop slabs. Expect deeper and more sensitive deposits at upper elevations and in lee features, these places are most suspect to human triggers.
Summary
Confidence
Low - Intensity of incoming weather systems is uncertain

Avalanche Summary
On Monday, wind-loaded pockets were reactive to skier traffic, including 2 very small unsupported pockets remotely triggered (from a distance) by skiers.Information from this region is limited. Tell us what you see by posting to the Mountain Information Network! (MIN)
Snowpack Summary
Up to 20 cm recent snow has been redistributed by wind and formed slabs in the alpine and treeline. Deeper and more sensitive wind deposits are likely to be found at higher elevations and in wind-loaded areas. Incoming snow may not bond well this wind-pressed surface.In total, 60-100 cm covers a weak layer of surface hoar (feathery crystals) and facets (sugary snow) that formed during the dry spell in early December. Information about about how well the December snow is bonding to this layer is limited in this region. Deeper in the snowpack, there are several crusts including an early season crust with facets near the bottom of the snowpack.
Problems
Storm Slabs
60-100 cm of recent new snow has been redistributed by strong winds. More snow on the way will form new slabs, and bury and add load to older wind slabs. Expect deeper and more sensitive wind deposits at higher elevations and in wind-loaded terrain.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Minimize exposure during periods of heavy loading from new snow and wind.Be cautious as you transition into wind affected terrain.
Aspects: All aspects.
Elevations: All elevations.
