Conditions are improving, however a basal instability still exists. Remain vigilant with route selection.
Summary
Weather Forecast
Clear skies and temperatures in the -10 range are expected for the next three days. Little change is expected within the snowpack during this time.
Snowpack Summary
In the alpine a few cm`s of new snow overlies widespread wind slabs created by recent strong SW winds. At treeline and above, mild temperatures have helped strengthened the upper snowpack but the basal rain crust/facets remain weak. Below treeline a rain crust is present and the moist snow is gaining strength rapidly with the cooler temps.
Avalanche Summary
No avalanches were observed or reported in the forecast region today.
Confidence
Due to the quality of field observations
Problems
Deep Persistent Slabs
Natural avalanche activity has tapered off but snowpack tests show that the weak facets at the base of the snowpack continue to be a concern. With a stronger upper snowpack, triggering an avalanche is less likely but the consequences remain serious.
Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of thin areas that may propogate to deeper instabilites.
Aspects: All aspects.
