Storm slabs are building at treeline and above over a weak and unstable snowpack below. Below treeline the snowpack is unsupported with weak facets and depth hoar.
Avalanche Summary
With whiteout conditions and steady snow there have been no reported avalanches due to poor visibility. However, the danger and likelihood of natural avalanche is currently high and will remain so until the weather system passes. All avalanche terrain should be considered suspect and avoided as large far running avalanches are expected.
