Avalanche danger ratings are for the Terrace area based on 10-15cm of new snow by Saturday morning. New snow accumulations have been much higher in North of the region where the Avalanche Danger is rated as HIGH.

Avalanche Summary

Although observations were limited on Friday, significant avalanche activity is expected in response to the current weather pattern, particularly in the north of the region where snowfall amounts have been the highest.

Snowpack Summary

As of Friday, variable amounts of new snow (~5-15cm in the south/ ~50cm in the north) were shifted into stiff and significantly deeper wind slabs at higher elevations while rain penetrated snow surfaces at lower elevations. The new snow overlies heavy accumulations from earlier in the week that have most likely gained considerable strength. I would imagine that with the ongoing weather pattern, significant cornice development has also taken place.The mid and lower snowpack layers are generally well settled.
