Avalanche Summary

A few size 1 wind slabs have been triggered by skiers this week.

Snowpack Summary

North and west winds have created isolated wind slabs 5 to 10 cm thick on lee slopes. On other slopes you may find tired old wind slabs, a sun crust on all solar aspects, surface hoar, surface facets, and/or up to 5 cm of soft snow over a widespread supportive rain crust in wind sheltered areas. The snowpack is generally strong and well settled. However, large cornices may become weak with daytime warming.

Problems

Wind Slabs

Outflow winds have created small wind slabs on lee and cross-loaded slopes. These can be triggered by the weight of a person. Also, keep an eye out for large unstable cornices that threaten your route.

Use ridges or ribs to avoid pockets of wind loaded snow.>Be cautious as you transition into wind affected terrain.>Give cornices a wide berth when travelling on or below ridges.>

Aspects: North, North East, East, South East, South, South West, West.
