Avalanche Summary
No recent avalanches have been reported in the region, however there are currently very few field observations.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
Up to 20 cm of new snow with southerly winds will continue to form wind slabs on lee features at upper elevations. This new snow sits over a crust up to 1400 m on all aspects.
Two layers of surface hoar can be found in the top meter of the snowpack at treeline. These layers are generally no longer a concern, the exception being shallow rocky areas at upper treeline.
The current snowpack has considerable variation in structure and depths across the region and is shallow for this time of year.
