Glacier

Avalanche conditions are improving but a weak layer remains in the snowpack within range of human triggering and should be considered in your terrain decisions.

The snowpack is at record low levels with many hazards above or just below the surface, allow extra time for your decent and exit.

Sunshine and warm temperatures triggered a loose wet avalanche cycle on Saturday up to size 2.5. One loose wet avalanche was observed to step down to the Dec 1st surface hoar triggering a large slab avalanche that ran to the valley bottom.

5cm of new snow sits over a sun crust on solar aspects and wind effect in the alpine and exposed tree line. Sheltered N aspects hold soft snow.

Below 2100 m there is a strong rain crust down 40-60cm (from Dec 5th/6th).

The Dec 1 surface hoar is down 60-100cm, and continues to produce sporadic isolated avalanches.

In shallow areas at upper elevations, the base of the snowpack is faceted and unsupportive.

The ridge of high pressure rebounds on Monday bringing fairly calm weather with a few flurries.

Mon: Cloudy, no snow, light SW winds, high -7 °C, freezing level: 1200m.

Tues: Cloudy with sunny periods, no snow, light SW winds, high -6 °C, freezing level 900m.

Wed: Cloudy with sunny periods, no snow, light SW winds, high -4 °C, freezing level 1100m.
