Avalanche Summary
No recent avalanches have been observed in this region.
Snowpack Summary
Wind slabs are reported as being widespread and reactive at treeline and alpine elevations. Below treeline, recent snow is likely settling and gaining strength.There are a few deeper weaknesses in the snowpack. Professionals are still tracking a layer around 150 to 200 cm deep, composed of sugary faceted grains, feathery surface hoar, and a sun crust. The base of the snowpack may also still be composed of weak faceted grains in parts of the region. The likelihood of triggering these deep weak layers is low and would most likely be triggered by humans in areas where the snowpack is shallow.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
