Avalanche Summary
No recent avalanches have been reported in the region. We suspect that rider triggerable wind slab will be found on Friday.
If you do go into the backcountry, consider submitting a Mountain Information Network report.
Snowpack Summary
Up to 15 cm of new snow accompanied by moderate southwest wind will likely form wind slab throughout the day on north and east aspects.
A crusts can be found down around 50 cm on terrain below 1200 m, except on wind scoured slopes where it could be on the surface.
The snowpack is now above threshold for avalanches on smooth slopes at treeline. The snowpack in general is shallower than usual for this time of year and early season hazards are still a concern.
