Avalanche Summary
No avalanches were reported in the region on Sunday.
Snowpack Summary
The snow surface has been impacted by warm air temperatures, the sun, and recent strong northwest winds. Above 2000 m, you will likely find a melt-freeze crust on southerly aspects, wind-loaded terrain features on southwesterly aspects, and dry, wind-effected snow on northerly aspects. Below 2000 m, expect to find a crust on all aspects.Beneath this, around 40 to 60 cm of snow sits on a melt-freeze crust on south aspects and a spotty weak layer of surface hoar or sugary faceted grains. There have been no observations of avalanches on this layer and snowpack test results suggest the overlying snow is bonding to the layer. Where this layer exists, it is most likely to be found between 1700 m and 2000 m.The remainder of the snowpack is currently well-settled and strong in most locations.
