Avoid avalanche terrain.
Large natural and human triggered avalanches are likely.
New storm and wind slabs will form throughout the day. The largest and most reactive slabs will likely be found on north and east aspects at higher elevations.
One size 1.5 natural wind slab avalanche was observed on a steep north facing alpine feature on Thursday.
Several wet loose avalanches up to size 2 were observed on steep south facing terrain on Thursday as well.
By the end of the day on December 7th up to 50 cm of new snow may have fallen. This new snow will overlie a variety of surfaces including a sun crust on steep south aspects and Surface hoar on northerly aspects.
The mid snowpack is generally well settled, with an early November crust buried 50 to 100 cm deep.
Snow depths at treeline range from 100 to 170 cm and decrease quickly at lower elevations.
