UPDATED AT 07:45 AM. The snowpack needs time to adjust to the new snow load. Use cautious route-finding and avoid alpine terrain.

Observations during the storm have been limited due to poor visibility. On Wednesday and Thursday our field team observed size 1-2 storm slab avalanches.

On Tuesday, they remotely triggered a large (size 2) storm slab near the Fraser Chutes, which stepped down to the persistent weak layer. Check out their MIN report.

Light snowfall continues to accumulate. Since the start of the week, around 50 cm has fallen. Strong southerly winds have formed deeper deposits on northerly aspects.

The recent snow sits over a 20 to 30 cm thick layer of old faceted snow. Below 1700m, these facets sit over a crust. Recent avalanches have been observed to have failed on this layer.

The rest remainder of the snowpack is well bonded and settled. Snowpack depths range from about 100 to 180 cm.

Thursday Night

Friday

• Travel in alpine terrain is not recommended.
• Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
• Use conservative route selection and resist venturing into complex terrain.
• Storm slabs in motion may step down to deeper layers resulting in large avalanches.
