With continued snowfalls, human-triggered slab avalanches will remain a concern, especially on wind-loaded features.
Rider-triggered storm slabs remain possible as new snow and wind form fresh, reactive slabs, particularly on wind-loaded lee slopes where deeper snow deposits are found.
On Friday, a cornice fall triggered a small wind slab avalanche (size 1.5) on a cross-loaded slope near Thar Peak. Several loose wet avalanches were observed on steep southerly slopes in the Coquihalla.
On Thursday, a skier triggered a size 1 avalanche on a northeast aspect at treeline in the Coquihalla. Read full MIN here.
Over the weekend, 15 to 25 cm of new snow will add to 65 cm of recent storm snow. This sits above a crust on all aspects except on high, north-facing alpine terrain. Moderate to strong southwest winds have redistributed storm snow into deeper pockets on lee slopes at ridgeline, forming wind slabs.
A layer of facets and surface hoar that formed in February has been found 90 to 150 cm down, and a layer of facets and surface hoar from late January can be found down to 130 to 190 cm. No recent notable test results have been seen on these layers.
