Avalanche Summary

No new avalanches were reported over the weekend.

Snowpack Summary

Strong outflow winds (mainly from the north) have created areas of wind slab on lee slopes. On other slopes you may find 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.

Avalanche Problems

Wind Slabs

Winds out of the North and Northwest have created small new 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.
Be cautious as you transition into wind affected terrain.>Give cornices a wide berth when travelling on or below ridges.>Use ridges or ribs to avoid pockets of wind loaded snow.>

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