Weather Forecast

Westerly wind and snowfall amounting to 10-15cms forecasted for Saturday overnight.

Snowpack Summary

35cm of storm snow settling rapidly and beginning to slab up with the warmer temperatures and wind; which was packing a punch in the Ice fields area Saturday. From the top down, snowpack has an upside down feeling to it right now, with the warm heavier snow on top and the cooler below. Lots of snowballing and loose slides seen below tree line.

Avalanche Summary

Snowballing and pinwheels observed at roadside but limited visibility above. Snowline at 1500m, rain below and a highly variable freezing level observed on the parkway today.

Confidence

Intensity of incoming weather systems is uncertain
