Dangerous avalanche conditions continue due to significant snow accumulation throughout most of the region, and conditions may vary.
Reactive storm slabs continue to form as stormy conditions persist, particularly at higher elevations where wind loading is likely creating larger, more reactive slabs.
While no avalanche activity has been reported, we expect a natural avalanche cycle to be occurring, particularly in regions receiving higher snowfall amounts.
Observations remain very limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network
Over the past week over 100 cm of new snow has accumulated in some areas. This recent snowfall has formed reactive storm slabs at all elevations, contributing to an elevated avalanche hazard.
In the mid-snowpack, a crust formed in early November may still be present, potentially accompanied by surface hoar and/or faceted crystals. This layer could become a source of instability as new snow continues to accumulate, creating a heavier load above.
The lower snowpack is characterized by several old melt-freeze crusts, with depth hoar crystals present at the base in some areas.
At treeline, snowpack depth ranges from 100 to 200 cm.
