    The new snow may be sitting on a hard layer like an old wind slab or a sun-crust. There may also be a weak layer of surface hoar or facets sandwiched between the new snow and the old surface. Pockets of deep soft new wind slab may also be found.

Confidence

Poor - Due to variable snowpack conditions for the entire period

Avalanche Summary

Loose snow natural and skier controlled avalanches up to size 1.0 were reported from the Kootenay Pass area.

Snowpack Summary

Recent snow fall amounts have been variable across the region. Some areas have about 30 cms that is reacting to light additional loads, and sliding on the weak surface hoar layer that was buried on the 23rd of January. Some other areas only had 10-15 cms with lighter winds, and the new snow has not formed a reactive storm slab. Due to this variability, it is difficult to rate the danger for the entire region.
