Avalanche Summary
No avalanches were reported in this region on Friday. However, we currently have very few observations from within this region. Please post your observations to the Mountain Information Network. (MIN)
Snowpack Summary
We currently have very limited snowpack observations, so it is critical to supplement this information with your own observations.In many areas, other than the highest accessible alpine areas, the entire snowpack may be moist. As temperatures are cooling, the snowpack is beginning to freeze from the surface downwards. Some reports indicate there may be an early season crust near the bottom of the snowpack. There is an average of 70-120 cm of snow in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks.
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.
