Weather Forecast

There is a gradual warming trend where highs will reach minus 12C by Sunday and lows will be around -16C. The Arctic high continues to dominate the weather until early next week.

Snowpack Summary

5-10 cm of recent snow sits on the January 30th surface hoar below treeline. In the alpine this recent snow is over a firm wind slab or a thick sun crust on S & W aspects. The basal facet layer is dormant for now in the current weather pattern.  It will become active again once we get more snow and wind.

Avalanche Summary

No new avalanches have been observed or reported.

Confidence

The weather pattern is stable

Avalanche Problems

Deep Persistent Slabs

There has been no avalanches on this layer for two weeks.  It is very unlikely this layer will be triggered while we remain in the Arctic high weather system.  This layer will wake up again with more snow and wind loading.
Be aware of thin areas that may propogate to deeper instabilites.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 1 - 2
