Regions: Sea To Sky.

The deepest riding is in the alpine. Watch out for lingering wind slabs.

Confidence

Low - Due to the number of field observations

Avalanche Summary

No avalanches were reported in the region on Saturday. Small natural and skier-triggered storm slab avalanches were observed out of steep, wind-loaded terrain at alpine elevations on Friday.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!

Snowpack Summary

The deepest snow is found at alpine elevations, with amounts around 60-100 cm. Approximately 30 cm of new snow lies above previous wind slabs that formed with strong southerly winds on Wednesday. Below this lies a thin crust, now buried around 50 cm. A thicker lower crust, that may be associated with weak faceted crystals in some places lies close to the ground. This is most likely to cause problems in glaciated terrain or on high slopes where the summer snow did not melt out.

Avalanche Problems

Wind Slabs

Pockets of wind-loaded snow may exist in exposed areas behind ridges and peaks.
Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Cornices are already large and looming near ridges. Give them a wide berth.
