Watch for storm slabs building throughout the day.
Stick to conservative terrain, very large avalanches have occurred in the region.
A buried crust has produced a recent widespread cycle of natural and human-triggered avalanches in the region. Remote triggering and step-down potential are both a concern with this layer.
Wind and recent snow are forming storm slabs at all elevations.
Avalanches in motion may step down to deeper layers in the snowpack creating larger than expected avalanches.
Jan 2
Explosive control produced a few size 1.5 slabs in steep treeline terrain.
Dec 31
A very large naturally-triggered size 3.5 avalanche failed on the persistent weak layer.
Dec 30
A large (Size 2.5) remotely triggered persistent slab avalanche was reported in the Bullmoose riding area, near Tumbler Ridge. See the MIN for more details
A widespread natural avalanche cycle was reported in the Tumbler Ridge area, with avalanches up to size 2.5 on a variety of aspects.
Recent snowfall has been blown into slabs in leeward alpine and treeline terrain by winds from variable directions.
An additional 5 to 20 cm is forecast for the region by Sunday afternoon, with the highest snow amounts set to fall in the western Kakwa area.
A persistent weak layer formed in mid-December that consists of a prominent crust with weak facets, was the cause of a recent large natural avalanche cycle. This layer is now buried 50 to 170 cm deep, depending on the aspect and wind loading.
In thin snowpack areas, faceted grains or depth hoar may exist at the base of the snowpack.
