Lower danger ratings in the alpine should not be seen as
carte blanche for bigger terrain.

Avalanche Summary
No reports of big natural avalanches in the Alpine yesterday. There were a number of skier controlled avalanches to size 1.5. These avalanches were failing as soft slabs in wind exposed terrain.
Snowpack Summary
An average of 150 cm of storm snow fell in the last 10 days across the region. Winds picked up Wednesday/Thursday of this week forming large wind slabs in the Alpine. This generated a limited avalanche cycle to size 3 that persisted through Friday. It sounds like these slabs are settling out but I'm still suspect of them, especially on steep unsupported features. New (relatively) thin wind slabs involving Saturday nights snow may still be an issue Monday. There are some reports of a suncrust down around 100 cm in steep south facing features. The mid-pack is reported to be well settled. I haven't heard of any test results involving the late November surface hoar in the last five days. The early November crust, near the base of the snowpack has also been inactive as of late. It's important to note that professionals are still cautious about these lingering persistent slab problems, but the likelihood of triggering is low. Be wary of steep complex terrain with a shallow snowpack, where triggering a persistent weakness is more likely.
