Northwest Inland

Recently formed storm slabs and wind slabs will continue to be reactive to human-triggering. Conservative terrain selection remains very important.

Moderate - Timing, track, or intensity of incoming weather system is uncertain on Sunday

Unsettled conditions continue, bringing a trace of new snow Friday night. On Saturday, freezing levels will fall to1000 m with a mix of sun and cloud. Alpine temperatures -4 and ridgetop winds will be moderate from the South. Sunday will be mostly cloudy with a trace of new snow. Alpine temperatures -5 and freezing levels 800m. Ridgetop winds will blow moderate-strong from the south. Monday will bring a mix of sun and cloud with alpine temperatures -7 and moderate-gusting strong winds from the West.

On Thursday no new avalanches were reported. Earlier in the week smaller isolated storm and wind slabs were reported. If the sun comes out, natural avalanches are possible on steep south facing terrain features. In the far north, deeply buried persistent weak layers may still be reactive to large triggers such as a small avalanche stepping down or a cornice failure.

Recent storm snow accumulations are 40-80cm over the past week and overlie a melt freeze crust which extends up to around 2000m elevation. This recent snow is reported to be bonding well to the crust. Moist snow was reported below 1200m on Wednesday and wet snow below 800m. Recent wind has redistributed the surface snow at higher elevations forming wind slabs in leeward features. The early January surface hoar/facet layer is down around 1m+ and remains a concern for commercial operations. This layer seems the most reactive in the north of the region but may still be a concern in the south as well. Shallow snowpack areas in the east and north of the region may have a weak base layer of facetted snow on or just above the ground.
