Fair - Wind effect is extremely variable
Weather Forecast
Apart from some light snow or flurries late on Sunday, the next few days look dry and cool, with mainly moderate northerly winds.
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.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
