Confidence

Poor - Due to the number of field observations

Weather Forecast

Monday/ Tuesday/ Wednesday: Very cold and mainly 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 last 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 [email protected].

Avalanche Problems

Storm Slabs

Recent snow and wind may have created storm slabs or wind slabs. In some parts of the region, it's possible that storm slabs overlie a deeper weak layer possible of creating a surprisingly large avalanche.

Choose regroup spots that are out of avalanche terrain.>Avoid freshly wind loaded features.>Be alert to conditions that change with elevation.>
