Avalanche Summary
Numerous storm and wind slab avalanches were reported on Wednesday, during stormy conditions. Avalanches occurred on various elevations and aspects and were a mix of natural and skier-triggered up to size 2.
If you head into the backcountry, please consider submitting a MIN report.
Snowpack Summary
Up to 30 cm of recent, low-density snow has been redistributed by variable alpine winds. Below the new snow are various old surfaces, including firm wind-affected snow, faceted crystals, and surface hoar, all of which may prolong the bonding between new snow and underlying surfaces.
The mid and lower snowpack contains various old crusts and is generally well-settled and stable.
With recent snowfalls, lower elevation areas may now be at the threshold for avalanches.
