New snow and wind are making dangerous avalanche conditions.
Storm slabs built up over the preceding days are likely, especially in wind-loaded terrain.
Up to 100 cm of recent snow has formed widespread storm slabs, with potential for large avalanches. These slabs need to more time to settle and bond.
This MIN post describes recent touchy storm slabs at the Longworth Lookout area.
Additionally, a very large naturally-triggered size 3.5 avalanche was reported just outside the eastern border of the region on Dec 31.
Up to 100 cm of snow has fallen in the region over the last few days and 30 more is expected through the day building deep and reactive storm slabs, with continued potential for large avalanches.
The prominent mid-December crust is buried up to 150 cm deep and extends to 2200 m. Triggering this layer is considered unlikely, except with large loads.
