Weather Forecast

A ridge of high pressure is bringing the heat for the weekend and into next week. Watch for freezing levels to rise.For the Columbia Icefield Area:Saturday Cloudy with sunny periods.Precipitation: Nil.Treeline temperature: High -4 C.Ridge wind west: 10 km/h.Freezing level: 1800 metres.

Snowpack Summary

Moist surface snow treeline and below and the alpine is heavily wind effected. Deep snowpack areas are relatively strong through most of the region. Shallow areas are weak, and will morph quickly to moist 'spring like' slab conditions from the surface down. With the persistent basal weakness, this could fail with the full depth of the snowpack.

Avalanche Summary

On Friday several loose wet avalanches on steep, solar, rocky below treeline features and a windslab avalanche in the alpine on a cross-loaded south feature at 2500m Tuesday a group of skiers triggered a wind slab in the backcountry behind Marmot Basin. It was on a north alpine aspect with shallow snowpack, scree ground, and severely wind affected.
