Heavy snowfall and drifting earlier in the week overloaded slopes plagued by very weak, sugary, or faceted snow, elevating the avalanche danger.
- Avalanches of wind-drifted snow are possible in drifted terrain where wind slabs have formed on slopes with poor snow structure. These could be 1 ' to 2' thick and perhaps 30 to 60 feet wide.
- Some soft slab avalanches could step down into faceted snow near the ground.
- Cracking and collapsing or "whumpfs" are red flags indicating unstable snow.
- Although the likelihood diminishes with the stagnant weather, avalanches might still be triggered remotely or from a distance.
