Red Flags Comments: 
Main red flag was the wind.
Avalanche Problem #1
Type: 
Wind Slab
Problem #1 Comments: 

Lots of easily triggered wind slabs along mid-elevation ridgelines. Didn't venture into the upper elevations due to high winds. Wind slabs ranged from 6" to over 2' deep. See separate avalanche observation.

Avalanche Problem #2
Type: 
Persistent Slab
Trend: 
Same
Problem #2 Comments: 

Outside of wind zone, was noticing that there was beginning to be just enough snow to ski cut small pockets that were failing on faceted snow formed around a wind crust last week. In tests, we could not get propagation as there was not quite enough of a slab, but with settlement tomorrow and a bit more snow things may become more connected. See snow profile and photos below.
