Summary
Confidence
Poor - Due to the number of field observations
Weather Forecast
Sunday/Monday/ Tuesday: Very cold and dry. Mainly light winds.
Avalanche Summary
We've had no avalanche reports since the weather cooled down. During the previous warm, rainy period, a widespread loose wet and wet slab avalanche cycle to size 2 was observed in the south of the region. We had reports of whumpfing and collapsing at treeline in the north of the region.
Snowpack Summary
Around Kootenay Pass, rain moistened the snowpack to perhaps about 2000m on Thursday. It's expected that the snowpack in this region has now strengthened considerably. This region received 15 cm of storm snow on Friday night, which may have created pockets of wind slab or storm slab at upper elevations. Above about 2000m and in the north of the region, I have the most avalanche concerns. It's these areas which may be harbouring a weak layer (formed during November's dry spell), now buried with this week's accumulated snow. We have very limited field information. If you have been out in the mountains, we'd love to hear from you. Please email us at forecaster@avalanche.ca.
Problems
Storm Slabs
Recent snow and wind may have created slabs on lee (downwind) slopes. In some parts of the region, it's possible that storm slabs overlie a deeper weak layer possible of creating a surprisingly large avalanche.
Be alert to conditions that change with elevation.>Avoid freshly wind loaded features.>Ride slopes one at a time and spot for your partners from safe locations.>Choose regroup spots that are out of avalanche terrain.>
Aspects: All aspects.
