New snow and wind continue to stack up, creating dangerous avalanche conditions.
The best and safest riding will exist in lower-angled, sheltered terrain with no overhead hazard.
Snowfall and wind on Sunday will continue to build storm slabs, which will be deepest and most reactive in wind-loaded terrain.
Storm slabs may overlie a weak layer, which could result in wide propagation and remote triggers.
No recent avalanche activity has been reported at this time.
Storm snow has stacked up in the past week, and could be reaching a tipping point for large, reactive slab avalanches. Learn more in our recent conditions update. We expect the likelihood of both natural and human-triggered avalanches to increase in the next few days as snowfall, wind, and warming impact the region.
Please consider posting a MIN if you are heading out in the backcountry!
As much as 60 cm of recent storm snow has accumulated in the past 3 days. This will create a significant new load, with 40 to 80 cm of recent snow now overlying a surface hoar layer in sheltered terrain and a thin sun crust on south-facing slopes, and a generally faceted upper snowpack.
A supportive melt–freeze crust is found 60 to 90 cm below the surface in the mid-snowpack.
Average treeline snow depths range from 90 to 140 cm, tapering off quickly at lower elevations.
