Avalanche Summary
We're working with limited observations but there haven't been any reports of recent avalanche activity. However, the avalanche cycle that occurred during and immediately after last weeks storm produced some large natural avalanches.
Snowpack Summary
Total snowfall from Monday's storm should be between 5 and 30 cm which is coming to rest on a wide variety of old surfaces including crust, surface hoar and old settled snow. Moderate to strong SW winds likely continue to form pockets of wind slab on east and northeast aspects. A couple of persistent weak layers exist in our early season snowpack. Where they exist, they are likely to be found buried down 65 to 120 cm. Depending on where you dig, you might also find one or more crusts. It would be wise to test these layers before committing to a slope. Facets can be found at the bottom of the snowpack at higher elevations in the alpine, especially on northerly aspects. Rocks and stumps may be lurking unseen just below the surface.
