Avalanche Forecast

Low - Uncertainty is due to the limited number of field observations.

SATURDAY NIGHT: Mostly cloudy with isolated flurries; 0-3 cm / Moderate, southwesterly winds / Low of -14

SUNDAY: Snow; 5-10 cm / Strong, southwesterly winds / High of -11

MONDAY: Mix of sun and cloud / Strong, southerly winds / High of -10

TUESDAY: Cloudy with flurries; 3-5 cm / Strong, southwesterly winds / High of -10

Strong southwesterly winds have formed large wind slabs reactive to human triggers on lee features.

With uncertainty about the snowpack structure, it may also be possible to trigger large avalanches from thin areas on big alpine slopes. Until there is more information about the snowpack we recommend an extra-cautious approach and careful snowpack evaluation, especially in high-consequence terrain.

30+ cm of recent storm snow and strong southwesterly winds have formed thick wind slabs reactive to human triggers.

A persistent weak layer of facets over a crust near the bottom of the snowpack has been reported as being reactive to human triggers near Fraser. See MIN HERE.

• Avoid freshly wind loaded terrain features.
• Use ridges or ribs to avoid areas of wind loaded snow.
• Be aware of the potential for large avalanches due to the presence of a persistent slab.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Avoid shallow snowpack areas, rock outcroppings and steep convex terrain where triggering is most likely.
