Forecasted snow (5-8cm) shouldn't be enough to overload persistent weaknesses in the upper snowpack. Due the variable distribution of these layers it would behoove you to keep monitoring the sensitivity of any slope before you commit to riding it!
Weather Forecast
The incoming storms have mostly blown themselves out by the time they get into the forecast area. For Wednesday, expect as much as 5 to 8cm overnight the through the morning Thursday. Alpine High -6C. Ridge wind light to moderate SW, gusting to moderate values.
Snowpack Summary
Windslab continues to build in open areas and sits above 3 weak interfaces in the top 30 to 50cm of the snowpack. The distribution of these surface hoar/facet layers varies with the terrain, but is most predominant in lee features at TL and into the alpine. Field teams continue to monitor the sensitivity of these layers carefully, as should you!
Avalanche Summary
Natural avalanches up to size 1.5 were observed Tuesday in windswept alpine moraine features. Appears to be running on the persistent slab interface dow 30 to 50cm.
Confidence
Forecast snowfall amounts are uncertain on Thursday
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.
