Southwest winds have formed deposits of reactive wind slab.
Seek out sheltered terrain.
Southwest winds have formed reactive slabs. Watch for corniced ridges, cross-loaded features, and convex rollovers.
These slabs may step down to deeper layers with large loads, producing larger-than-expected avalanches.
A few size 1.5 wind slab avalanches were reported by the Field Team in the Nadahini area on Thursday, failing below corniced ridgeline features.
Skiers triggered reactive wind slab deposits on north- and east-facing slopes near Haines Junction.
If you go into the backcountry, please submit your observations to the Mountain Information Network.
Moderate and strong south winds have redistributed 20 to 25 cm of new snow. Deeper, more reactive deposits exist in leeward terrain. Many windward features are stripped back to the ground.
A weak layer of faceted crystals or surface hoar found 50 to 80 cm deep remains a concern. The midpack is generally facetted to the ground.
The average snowpack depth at the treeline is around 150 cm.
