Winds are expected to pick up the next few days which will likely create new wind slabs in lee features. Avalanche and riding conditions will depend largely on what the wind does. Our neighbors to the south have been seeing avalanches on the October crust, so its a good time to stay vigilant.
Be mindful of newly formed windslabs if the wind picks up. Older windslabs are also still present and could be sitting on a crust or facets, which may increase their potential for triggering.
The Oct 18 crust is found just above the ground with weak facets above and below it. There’s uncertainty around its distribution and triggerability. More activity has been observed to the south of JNP, but limited observations make it hard to predict when and where it may be a problem.
