Heavy snowfall combined with strong southwest wind Tuesday night has likely created storm and windslabs slabs at uppermost elevations.
Tuesday night's storm deposited up to 40 cm of new snow at uppermost elevations. As a result storm and wind slabs at upper treeline and in the alpine are the main concern on Thursday.

Wednesday Night: Clear periods, light south wind, treeline high temperature near -1 C, freezing level 1200 m.
Thursday: Mix of sun and cloud, light to moderate southeast wind, treeline high temperature 6 C, freezing level rising to 1500 m.
Friday: Snow or rain, 10-15 cm, moderate south wind, treeline high temperature 3 C freezing level 1300 m.
Saturday: Cloudy with flurries or rain showers, moderate southeast wind, treeline high temperature 4, freezing level 1400 m.
There are no recent avalanches to report, although I would expect an increased likelihood of triggering storm and wind slab avalanches at uppermost elevations as the most recent snow has a chance to settle and bond over the next few days.
Recent storm totals for the last week at upper elevations are upwards of 200 cm. This snow has likely seen extensive wind effect but we have received no alpine observations. Recent snow may contain and/or sit on a crust. At lower elevations, the previously rain soaked mid to lower snowpack will be dense and refrozen, or still wet below 1000 m.
The remainder of the snowpack is well-settled.
