Weather Forecast

There are two distinct weather systems over our forecast area. To the north, cold temperatures (-16) and light flurries are expected for the next two days. South of the Columbia Icefield  a much milder air mass has produced 30+ cm of snow.

Snowpack Summary

There are a variety of layers in the snowpack that relate to the early season snow, rain and freeze-thaw cycles. These can be consistently found in field tests but the depth of the weaknesses and the type of shears vary from slope to slope.

Avalanche Summary

Several natural avalanches to size 2.5 were observed today. All the slide activity seems to be wind slabs on steep lee and cross loaded slopes in the alpine.

Confidence

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