Avalanche Summary
We haven't received any recent reports of avalanche activity. Saturday night's storm will change conditions though. Riders could be able to trigger storm and wind slab avalanches in steep terrain at treeline and alpine elevations, particularly for areas that see more than 20 cm of snow accumulation.
Please consider sharing your observations to the Mountain Information Network.
Snowpack Summary
Snow is forecast Saturday night above 1000 m, which will build over a wettened snow surface and hard melt-freeze crust. Storm slabs could build within this new snow. The snow will come with strong southwest wind, potentially forming wind slabs in lee terrain features.
The remainder of the snowpack is strong.
There is insufficient snow to form avalanches for most below treeline locations.
