Forecast snow and strong southwest winds Monday night may form wind slabs reactive to human triggers.
Expect the danger to be Considerable in localized areas that receive more than 20 cm of new snow Monday night.
Forecast snow and strong southwest winds Monday night may form small wind slabs reactive to human triggers.
These slabs are most likely to form on lee features at treeline and above.
Cornices may be weak and reactive to human triggers. They create a significant falling hazard, and may produce large slab avalanches as they fall onto the slope below.
Cornice failures are more likely during hot and sunny weather.
Monday night: Snow; 10-15 cm / Strong southwest wind / Low of -9 / Freezing level 900 m.
Tuesday: Mix of sun and cloud / Light southwest wind / High of -1 / Freezing level 1400 m.
Wednesday: Sunny / Light southeast wind / High of 3 / Freezing level 1800 m.
Thursday: Mix of sun and cloud / Light southwest wind / High of 2 / Freezing level 1700 m.
No new avalanches were reported on Sunday.
10-15 cm of new snow and strong southwest winds are forecast for Monday night. This may form small wind slabs reactive to human triggers on lee features at treeline and above.
The recent snow is sitting on a variety of hard snow surfaces, including crusts and wind scoured snow. Below this, there are several crusts in the upper snowpack, but they are unlikely to be a concern in most areas until the next significant warming event.
