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.

Weather Forecast
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.
Avalanche Summary
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.
Snowpack Summary
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.
Terrain and Travel
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Be especially cautious as you transition into wind affected terrain.
Problems
Storm Slabs
Heavy snowfall combined with strong southwest wind Tuesday night has likely created storm and windslabs slabs at uppermost elevations.
Aspects: All aspects.
