Avalanche Summary
There are no recent significant observations to report at this time.
Snowpack Summary
20 - 30 cm of low density storm snow rests on a generally strong midpack. Recent west and southwest winds will have redistributed the new snow in alpine and treeline locations, creating windslabs on the surface. Persistent and deep persistent instabilities (surface hoar and an early November crust, respectively) located in the middle and near the bottom of the snowpack may still be a concern but there has been little recent evidence of them being reactive. It is important to know that we have very limited observations for this region. Digging down and making your own observations, especially in thinner snowpack areas, remains a good idea to assist safe slope selection. You're looking for weak layers that "pop or drop" in stability tests. If you are spending anytime in the backcountry, send us your observations. Every bit is greatly appreciated!
