Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

This last storm left us with up to 10cm of snow in the Spray Valley with locally higher amounts up to 15cm. All of the storm snow came with strong winds, so expect to find wind slabs in the Alpine and into Treeline that overly previous wind slabs. Approach all open areas with caution. If the wind slab is triggered, it is likely to bring the entire snowpack with it as the October crust/facet layer is located 20cm off the ground.

Weather Summary

Thursday: Mostly cloudy with sunny breaks and a high temperature of -7c. Winds are diminishing to moderate from the West.

More details can be found in the Mountain Weather Forecast.
