The incoming weather will determine the change, if any to the danger rating. Watch for local areas of higher accumulation, especially if there is wind. Other than that possible issue, the skiing is definitely worth heading out for.
Confidence
Moderate - Intensity of incoming weather systems is uncertain on Friday
Weather Forecast
Flurries will bring us almost 10cm's of snow by tomorrow afternoon. How these flurries arrive will be a bit of a question. Watch the timing of these small systems. If they come early and heavy, there may be enough load to change the avalanche hazard. As usual, the winds will pick up as the warm front arrives. The steady, moderate winds SW may amplify the local snow amounts contributing to a slight rise in hazard. From the looks of it, the cold air will fade away, leaving us with an alpine high of -6.
Avalanche Summary
Nothing to speak of, however field observations were limited today.
Snowpack Summary
Not a lot of change in the last 24hrs. Below treeline, the dec 4th surface hoar layer is down 30cm on average and still not producing avalanches of any character. The cold weather pattern is promoting surface faceting, which is keeping the surface snow loose. At treeline, the Dec 4th interface continues to be the layer to watch. We are seeing occasional shears within the top 40cm, but nothing consistent enough to suggest a widespread avalanche problem. The alpine has windslabs present near ridges and crossloaded terrain. Overall, we've seen about 2cm's of snowpack settlement throughout the forecast region.
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.
