Avalanche Forecast

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

The next storm has arrived and should produce 5-15 cm of snow by Sunday morning. An additional 5-10 cm is expected during the day and overnight on Sunday. There is a break in the action on Monday with flurries likely not amounting to more than a few cm. Current model runs show the interior back into a storm cycle on Tuesday with another 5-10 cm throughout the day. Snowfall amounts in the Monashees could be higher than forecast. Freezing levels should hover around 1100m and ridgetop winds are expected to remain light to moderate out of the south for the forecast period.

Numerous natural and human triggered avalanches size 1-2 were reported throughout the region on Friday. These avalanches occurred primarily below 1800 m, on all aspects. Of note, was a size 2.5 avalanche that was remotely triggered from 50 m away on Saturday. This speaks to the touchy nature of the buried weak layer. This trend is expected to continue throughout the weekend as the snow load increases.

A 40-60 cm storm slab overlays a variety of surfaces including large surface hoar, sun crusts, and facets. In recent days, the snow above this layer has settled into a cohesive slab and is ripe for human triggers, especially below 1800 m. Expect this slab to be thicker on lee features in the alpine. The mid and lower snowpack are generally well settled and strong.
