Avalanche Summary
Reports are very limited at the moment but the storm slab is sensitive to human triggering and natural avalanches are possible.
Several large (size 2-2.5) storm slab avalanches occurred in the Lizard range near Fernie on Thursday.
Snowpack Summary
Recent snowfall amounts are around 40 to 50 cm in the last three days. The top of the snowpack is generally soft and gets firmer as you go down. A layer of surface hoar that has been reported in open areas at treeline and below is buried 60-70 cm deep.
The bottom of the snowpack has a crust from early November that is just above the ground.
Snowpack depth is 130 - 180 cm at treeline.
