In sintesi

Human triggering of slabs remains a possibility, especially at higher elevations. The weak basal facets are cause for concern in larger terrain features. Cautious route selection is advised.

    Wind slabs are found in the Alpine and open areas at Treeline. No recent natural avalanches have been associated with this problem, but human triggering is still possible, especially along ridge crests or in steep and unsupported terrain.

    Avalanches could step down to the basal October crust (or the ground) and involve the entire winters snowpack, especially in shallow snowpack areas. Some whumpfing has been experienced in recent days.
