Weather Forecast
Light flurries and a mix on sun and cloud are expected for the forecast period. Freezing levels are expected to sit between 1200m and 1400m. Winds should remain generally moderate from the southwest.
Avalanche Summary
I'm sure human wind slab triggering will be possible over the weekend. Check out the blue dot on our Forecast Region Overview Map for details on a recently triggered wind slab avalanche.
Snowpack Summary
New snow has landed on recently formed wind slabs and wind-scoured surfaces. Weaknesses buried in the upper snowpack include hard crusts, surface hoar, and/or surface facets. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Below treeline, the snow appears to be in a spring melt-freeze cycle.
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.
