Conditions Summary
Yesterday we had observations in the sub-alpine (up to 1900m) on a predominantly SE aspect. There was 5-10 cm of new snow in the trees with some evidence of wind loading (up to 30cm).
There were no observations in the alpine.

Daily Discussion
The storm continues! Approximately 31cm of snow has now fallen so far in this storm; winds have been consistently strong from the NW during this time; and more snow and wind is forecast today!
In the alpine, windslabs are the primary concern from the NW winds. Although there is no direct evidence, due to whiteout/blizzard conditions, we suspect that these windslabs are becoming touchier. Conservative route finding and careful snowpack evaluation are essential.
Also, beware of new cornice development. These cornices may be touchy and pull back further that you expect.
In the sub-alpine, the storm snow is reaching a critical amount and may react as a storm slab particularly in steeper terrain.
It is going to be a stormy day. Be prepared for whiteout navigation and carry an extra layer for the wintery conditions.
Forecast Confidence: STRONG
Avalanche Problems
Primary Problem
Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.
Secondary Problem
Evaluate snow and terrain carefully; identify areas of concern.
We need your eyes too. If you’ve been in the backcountry we’d love to know what you have seen. Every little bit helps.
