Cooling temps will help lock in the snowpack tomorrow. We are expecting a dusting of snow tonight. We'll see if its enough to get good dust on crust skiing.
Weather Forecast
Cooler temps and cloud cover tomorrow, and even a chance of some light snow. The daytime high will be just below 0C with the freezing level at 1800m. A short bit of snow is expected to come through tonight, but only leave 6cm. Alpine winds will be moderate from the SE.
Avalanche Summary
Nothing new today.
Snowpack Summary
Valley bottom snow tends to be refrozen, isothermic snow up to 2300m, all aspects. Above that, the true north aspects have dry snow and crusts on the remaining aspects. Windslabs are still present in north facing alpine terrain.
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.
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
