Cornices hang over ridges and may be triggered by sunshine or people travelling along ridgelines.
Cornice and wet loose avalanches are possible in steep terrain.
Use caution on sun-exposed slopes and always practice good travel habits.
Cornices hang over ridges and may be triggered by sunshine or people travelling along ridgelines.
Periods of sun will likely trigger wet loose avalanches.
Observations since the weekend have been limited to small, explosive-triggered cornices (size 1 to 2) and wet loose avalanches.
Following last week's widespread avalanche cycle, the persistent slab problem is now dormant and would likely require a very large cornice fall on an isolated slope to trigger.
Dry, settled powder may still be found on high north-facing slopes, while elsewhere, a daily melt-freeze cycle is creating a hard crust overnight that softens during the day.
Old persistent weak layers may still exist 1 to 3 m deep on high north-facing slopes, but they are rounding and unreactive under current conditions.
At lower elevations, the rain-saturated snowpack thins rapidly with elevation.
