Weather Forecast

Overnight cooling with am temps forecast to be -15 to -20. Trace amounts of precip. Generally light sw winds, gusting to moderate values over the day.

Snowpack Summary

Only trace amounts of snow below 1700m. Above 2000m, a generally 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

Minimal natural activity observed today; 1 small slab out of extreme terrain. Climbers should still remain vigilant as even triggering a small avalanche in a gully feature or above cliffs can have severe consequences.

Confidence

Due to the number and quality of field observations
