Given the right terrain feature the Dec 2 surface hoar layer may still be reactive to skier triggering below treeline.
Summary
Weather Forecast
The forecast is calling for light winds shifting from SW to NW and continued light precipitation with 5-10cm possible by Monday morning.
Snowpack Summary
The last storm dumped 100cm of snow which is now settling into a slab. The Dec 2nd persistent weak layer resides under the slab and consists of a surface hoar layer at and below TL and suncrust on alpine solar aspects. The weak layer remains reactive to stability tests in the hard range. 15cm recent snow now covers a supportive crust below 1700m.
Avalanche Summary
No new observations in the last 24 hours.
Confidence
Forecast snowfall amounts are uncertain
Problems
Persistent Slabs
80-100cm of storm slab sits on top of the Dec 2 persistent weak layer. This layer is in the form of surface hoar at and below treeline and suncrust on solar aspects in the alpine. The layer is producing hard results on field tests yesterday at 2100m.
Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.
Aspects: All aspects.
