Weather Forecast

Localized convective storms moving through the Icefields and Wilson regions. Actual amounts will very, from trace to 5 - 7cm overnight Wednesday. Temperatures will remain floating near -5. Light to moderate, gusty SE winds will be moving fresh snow in exposed areas.

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 to the recent snow has loaded northerly exposed slopes and ridge tops in the alpine, expect this to continue.

Avalanche Summary

Observed no new avalanche activity on highway 93N. Climbers should still remain vigilant as even triggering a small avalanche in a gully feature or above cliffs can have severe consequences.
