Unstable slabs may linger on steep wind-loaded slopes, including the lee sides of ridges and cross-loaded features.
Periods of sun may trigger natural wet loose avalanches on steep slopes.
Several natural and human-triggered storm slabs were reported Wednesday. They were size 1 to 2 and typically 20 to 30 cm thick.
Looking ahead, this storm snow snow will be most concerning on wind-loaded features (north and east aspects) and during times of sun-exposure (south and west aspects).
Tuesday’s storm delivered 15 to 30 cm of new snow at upper elevations with strong south winds. This snow is expected to stabilize quickly, except on wind-loaded and sun-exposed slopes.
This snow fell on a mix of crusts and moist or isothermal snow, depending on aspect and elevation.
The lower snowpack has undergone multiple melt-freeze cycles, forming a mix of crusts and dense rounded snow.
