When the traffic light turns green, you should still look both ways... It may still be possible to find trouble if you are looking for it. Check out the snowpack discussion for more information on places where problems may still linger.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches have been reported in the region.

Snowpack Summary

The snowpack is generally stable right now, but there is a weak layer of surface hoar (feathery crystals) and sun crust on steeper south facing slopes. This layer is down 30-50 cm. The surface hoar is most prominent at treeline. Recent snowpack tests in the region suggest that this layer is most problematic where the surface hoar is sitting on the sun crust. This combination will most likely be found on steep south facing terrain at treeline.At the base of the snowpack is a crust that formed in late October. Steep, rocky alpine terrain, with a shallow snowpack are the most likely areas to trigger this layer. It would likely take a large load such as a cornice fall to produce an avalanche on this layer.
