    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.

Weather Forecast

Expect cloudy skies and possible light flurries over the next three days. The freezing level makes a gradual rise towards 2000 m by Saturday, and may peak near 2300 m on Sunday. Winds are light to moderate from the SW to NW.

Avalanche Summary

A skier remotely triggered a size 1.5 wind slab on Tuesday on a SE aspect in the alpine. Otherwise there has been little recent avalanche activity.

Snowpack Summary

North and west winds have created isolated stiff wind slabs 5 to 10cm thick on lee and cross-loaded 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.
