Weather Forecast

A pulse of snow starting on Sunday (15cm in the Icefields area and 6cm in the Jasper area) will be accompanied by strong Westerly winds and rising temperatures.

Snowpack Summary

The snowpack is highly variable throughout the forecast region. Alpine elevations are very wind effected with some drifting at higher elevations from moderate to strong south westerly winds.

Avalanche Summary

One large avalanche observed running on steep rock slabs on Whistler Mountain which was likely triggered by redistributed blowing snow.

Confidence

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