Poor - Track of incoming weather is uncertain on Wednesday

Tuesday: 5-10cm snow. Strong westerly winds. Freezing level at valley floor.Wednesday/Thursday: Weather models show very different outcomes. Anything's possible - from dry conditions to moderate (locally heavy) snowfall, with strong westerly winds and a slight rise in temperature. Confidence is poor. Check in tomorrow for an update.

On Saturday, numerous avalanches were triggered by skiers and explosives. A few small, skier-triggered avalanches were reported on Sunday. They all failed in, or at the base of, the storm snow.

Recent dry snow (10-30cm) fell with little wind and has not developed into a slab in most areas. However, this is likely to change quickly as the wind picks up again. Below this, older wind slabs are stubborn to trigger. A buried rain crust extends to about 1800m. Above this elevation, buried old surfaces include sastrugi and wind slab. Buried surface hoar is not a major concern in the upper snowpack as it is spotty in its distribution and may be isolated to a few sheltered drainages. Concern for lower snowpack layers has diminished and remains only in shallow snowpack areas. Facets associated with a crust from mid-December and/or sugary facets at the base of the snowpack may still be a concern in shallow areas. Fragile cornices are still lurking.
