Weather Forecast
Sunday night: Cloudy with clear periods, alpine temperature -11 C, light south wind.
Monday: Cloudy with scattered flurries, up to 6 cm accumulation, alpine temperature -9 C, moderate southwest wind.
Tuesday: Snow, 10-25 cm accumulation, alpine temperature -8 C, moderate southwest wind.
Wednesday: Flurries, 5-15 cm accumulation, alpine temperature -6 C, light west wind with moderate gusts.
Avalanche Summary
Avalanches are decreasing in likelihood, but it still may be possible to trigger wind slabs in isolated pockets in the alpine.
Snowpack Summary
Snowline sits around 1200 m, and snow depths range from 70-140 cm at treeline elevations.
Recent wind affect on surface snow can be found at all elevations, and old, hard windslabs are found in the alpine and around ridgline. These slabs could be more reactive where they overly a weak layer of surface hoar (feathery crystals) that formed on a crust. The last week of cold temperatures has been slowly decreasing the strength of the upper snowpack.
A variety of crusts from late October are buried deeper in the snowpack (down 50-100 cm). Generally, the inactive weather pattern over the past week has improved overall snowpack stability in the short term.
Problems
