Continued northeasterly winds are expected to form reactive wind slabs on lee features at all elevations.
Recently formed wind slabs may remain reactive to human triggers for longer than is typical due to the weak facets (sugary snow) they are sitting on.
20-40 cm of recent snow and strong winds shifting from southwest to northeast have likely created reactive wind slabs on all aspects.

A naturally triggered size 2 wind slab avalanche closed the south Klondike highway early Tuesday morning near the north end of the highway corridor.

20-40 cm of recent snow and strong winds shifting from southwest to northeast have likely created reactive wind slabs on all aspects.
A weak layer of facets (sugary snow) has been reported down 20-50 cm in some areas.
The lower snowpack is made up of weak sugary snow. An avalanche at this interface is most likely to be triggered in shallow areas or with a large impact like a cornice fall or a larger wind slab avalanche that steps-down to these deeply buried weak layers.
