Incoming snow and wind will create fresh wind slabs. Monitor closely how the snowpack adjusts to the change on Monday.
Some new snow (~10CM) and increasing wind from the S-SW will likely produce wind slabs in the alpine by Monday morning.
The November basal facets and depth hoar have been mainly dormant in this region and we have seen few avalanches on this layer. The recent storm was a good test. Thin spots or places exposed to large loads like cornices are the greatest concern.
No new avalanches were observed or reported on Sunday.
Recent storm snow has settled to 20-30 cm above 2300 m. The storm snow sits over buried sun crusts that are present to ridge crests, and faceted layers on shady aspects. Multiple buried crusts are present in the top 50-70 cm on solar aspects. The basal depth hoar is present but is only a concern in thin areas. Low elevations have a temperature crust on all aspects.
Snow will start Sunday evening and up to 10cm could arrive by Monday. Temperatures will decrease Monday with the valley remaining around zero degrees and -10 in the alpine. Wind will pick up into the strong range in the early hours of Monday.
