    Outflow winds 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.

Weather Forecast

The next few days look dry and cool. Winds are moderate to strong from the north quarter (although wind direction will vary locally). Freezing level valley floor by night and rising to around 1000 m by day.

Avalanche Summary

No new avalanches have been reported recently. Small loose wet avalanches are possible on sun-warmed slopes and it may be possible to trigger thin wind slabs.

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.
