If you receive more than 20 cm of new snow in your area, the avalanche danger may be HIGH on Tuesday morning.

Moderate - Intensity of incoming weather systems is uncertain on Tuesday

Tonight: 10-15 cm of new snow combined with strong southwest winds and overnight freezing down to valley bottoms. Tuesday: 3-5 cm of new snow with moderate westerly winds and daytime freezing up to 1500 metres. Wednesday: Chance of flurries with moderate southwest winds and alpine temperatures around -5. Thursday: Chance of flurries with light northeast winds and alpine temperatures around -12.

On Monday, small natural and skier controlled slides continued up to size 1.5. Some explosives controlled avalanches were reported up to size 2.0. On Sunday, reactive storm slabs produced a few size 1.5 naturally triggered avalanches in alpine terrain, several size 1.5 skier triggered avalanches at treeline, and numerous size 2-2.5 explosive triggered avalanches in alpine terrain. Small loose wet avalanches were reported at lower elevations as well. On Monday, storm slabs will likely remain reactive to human triggers at higher elevations.

Forecast snow and strong southwest winds are expected to add to the 30 cm of storm snow that already exists. This slab sits above a thick rain crust below 1900 m and a generally well settled snowpack. Isolated basal weaknesses may still exist in shallow snowpack areas.
