Weather Forecast

Temperatures to remain cool over the weekend. A warm moist system expected in the region overnight Sunday. Bringing with it warmer temps and potentially up to 30cm of snow.

Snowpack Summary

Generally a strong, and supportive early winter snowpack exists with depths ranging from 30 to 100+ cm depending on aspect and exposure to wind. Wind effect on recent snow isolated to exposed slopes and ridge tops in the alpine. New snow remains well preserved on sheltered aspects.

Avalanche Summary

No new natural activity reported from a field team. Climbers should still remain vigilant as even triggering a small avalanche in a gully feature or above cliffs can have severe consequences.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Sunday
