Expect stiffer and deeper deposits of snow on northeast and southeast facing slopes. Watch for steep convex rollovers, ridgetop entrances, and cross loaded features.
Carefully evaluate steeper terrain for wind slabs, as there is potential for avalanches to step down to deeper weak layers.
Expect stiffer and deeper deposits of snow on northeast and southeast facing slopes. Watch for steep convex rollovers, ridgetop entrances, and cross loaded features.
A widespread crust with facets is buried 50 to 100 cm deep. Wind slabs may step down to this layer, producing large avalanches.
No new avalanche activity has been reported since the weekend.
Several natural and rider-triggered avalanches, up to size 2.5, were reported over the weekend. A number of these reports occurred on the weak layer from early December.
Recent snow has been heavily wind-affected in exposed areas. A crust exists below 1250 m, making for challenging travel conditions.
A weak layer, buried in early December, of facets and a crust is down roughly 50 to 100 cm from the surface.
