In sintesi

There are still concerns in wind-loaded areas and thin spots. There is a lot of variability with respect to aspect and elevation right now, so take some time to assess the snow where you are.

    The base of the snowpack remains weak due to the presence of basal depth hoar and facets. Natural activity is tapering off, however human triggering is still likely on this layer.
