Avoid all avalanche terrain.
Weather Forecast
Cold temperatures tonight and on Monday with temperatures near -22 °C with light East winds. A further 15cm is expected by the end of Monday. The sun may shows it's face again on Tuesday, but it won't warm up until later in the week.
Avalanche Summary
Numerous skier remote triggered avalanches up to size 1.0 on all aspects at Treeline and below. Trigger distances ranged from 3 to 40 metres. These avalanches were up to 30cm thick. and occurred on relatively low angle lightly treed slopes. Suspect numerous naturally triggered avalanches ranging from size 2.0 to 3.0 on all aspects. Visibility was very poor, and a few debris piles were directly observed today.
Snowpack Summary
Up to 50cm of new snow in the past 24hrs, with storm snow totals now as much as 80cm at Treeline now overlies the previously formed hard wind slab in most areas. At lower elevations the snowpack has doubled in just 2 days. Minimal wind effect at Treeline so far, but expect more in the Alpine (unconfirmed due to very poor visibility). Very touchy shears within the storm snow down 10 to 30cm, which were easily triggered remotely, from as far away as 40 metres, by the forecasting team today.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
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.
