Features of concern remain: ridgetop transitions with local winds creating surface slabs plus shallow locations where deeper instabilities could be triggered. Despite less natural activity, human triggered avalanches remain possible.
Weather Forecast
Temperatures will trend cooler the next few days with continued unsettled weather. A few centemetres every day this week with continued light winds. Expect winds to be stronger at some local ridgetop locations or higher alpine elevations.
Snowpack Summary
Minimal wind affect observed and 10-15cm of low density surface snow in most areas. Windslabs can be found in the alpine buried under last week's snow and may be developing at exposed ridgetops. Several small whumphs observed in shallow areas. Winds remain calm for the most part.
Avalanche Summary
Several loose natural point releases observed on in steep rocky terrain did not trigger slopes below. No new slab avalanches have been observed for 3 days. Caution is still warranted despite the decrease in natural activity.
Confidence
Wind effect is extremely variable
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.
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
